15. CONTROLS 15.1 Weighing The scale system on standard models includes four weigh-bars. The weigh-bars electronically measure the amount of ration inside of the mixing chamber. When attaching the indicator to the machine, be sure that it is securely fastened. On the A50, the scale indicator is located on the upper mixer drum (near operator). The mounting bracket arm assembly allows the scale indicator to be turned to face every direction. Be sure not to pinch the wire. NOTE - Tighten swivel joint lock nut to the point where there is enough friction to hold the indicator in position but it can still easily be turned by hand. Figure 13 - A50 Scale Mounting Bracket Arm Adjustment 1. Swivel Joint - Used to adjust the direction of the scale indicator face. 2. Scale indicator NOTE - The scale will be programmed to display weight in either kilograms (kg) or pounds (lbs). This is set by the manufacturer and must be ordered to suit. If your scale is not programmed to your preferred units of measurement, or for any other settings, please see your Mini Weighing System User Handbook which has been provided by the scale system manufacturer. Jaylor Operating and Maintenance Manual - 25 - A50 Series Models
15.2 Side Door Discharge On A50 self propelled, trailer and stationary models the side discharge door is controlled manually from the operator s platform. On the A50 truck mounted model, the door is powered by a cylinder and controlled remotely by a switch. On the A50 self propelled, trailer and stationary models, the door can be raised to three possible positions. The most suitable door opening height should be determined by taking into consideration the feed composition and the ground speed of the machine when unloading. 15.3 Speed/Direction Control Pedal (A50 Self Propelled Models) The A50 self propelled model has the ability to be driven by the operator. Speed and direction (forward/reverse) are controlled by a foot pedal on the operator s platform. Forward and reverse are indicated on the platform. The further the pedal is depressed either way, the faster the mixer will travel. When the pedal is released, the mixer will stop traveling. Figure 14 - A50 Self Propelled Speed/Direction Control Pedal 1. Speed/Direction Control Pedal 2. Reverse Arrow Cutout 3. Forward Arrow Cutout 4. Operator s Platform Do not protrude feet outside of platform while traveling. 15.4 Auger On/Off Control All A50 model augers are controlled using either a manual or electronic valve (refer to section 12. Machine Components for control locations). Auger rotational speed can be controlled by altering the engine speed. However, decreasing the engine speed will also decrease the output torque which under heavy loads could cause the engine to stall. Jaylor Operating and Maintenance Manual - 26 - A50 Series Models
15.5 Steering (A50 Self Propelled Models) The A50 self propelled model incorporates a reliable mechanical steering system. Rotation of the steering handle controls the direction of the machine. The machine is capable of turning almost 90 degrees in either direction (see Figure 15 below). NOTE DO NOT attempt to rotate the steering wheel while the mixer is not moving. This applies a tremendous amount of stress on all of the steering and wheel components and could reduce the lifespan of the system. Figure 15 - A50 Self Propelled Steering 1. Steering Handle 2. Steering Tire The hydraulically powered steering tire can be turned nearly 90 degrees either way which allows the mixer to turn almost on the spot if necessary. NOTE Some mixer components in this figure have been removed for clarity. 15.6 Throttle Control All A50 models which are powered by an internal combustion engine will have engine speed control. The A50 trailer and truck mounted throttles will be controlled directly by the engine throttle control lever. Locations are indicated in section 12. Machine Components. The A50 self propelled engine throttle is controlled remotely using a lever on the control console near the steering handle. Jaylor Operating and Maintenance Manual - 27 - A50 Series Models
16. DRIVING The A50 self propelled model is designed to be easily and conveniently maneuvered down narrow alleyways with sharp turns. The following outlines the procedure and possible hazards to be aware of while driving the machine. Think SAFETY! Work SAFELY! 1. Be sure all bystanders are clear of the machine and that there are no riders on the machine. 2. Be sure that the machine has plenty of fuel to reach its destination. 3. Start the machine as outlined in section 19. General Field Operation. 4. Stand securely on the operator s platform facing forward. Use one hand to securely hold the steering handle. 5. Check to make sure the steering tire is facing forward before driving. 6. Be well aware of your surroundings before driving. Do not drive if you feel the terrain or the situation deems it unsafe to do so. 7. When you are ready to proceed, make note of the cutout arrows on the platform as they will inform you which side of the speed/direction control pedal to press depending on which direction you want to travel. 8. Gradually depress the pedal downward until a comfortable and safe speed is reached. 9. Rotate the steering handle as needed to maneuver across the terrain. 10. Make sure you are always aware not only of the area in front of the mixer, but also behind and on both sides of the mixer. 11. Plan the route to your destination and make sure you are familiar with it. Always take the safest, most direct route. Avoid driving if visibility is poor. 12. When parking the mixer, place on a flat, level surface, put controls in neutral, apply parking brake if equipped (if not, block wheels), stop engine, remove ignition key, and wait for all moving parts to stop. The following is a list of feasibly dangerous situations that the operator may be faced with at some point. Please follow the recommendations given to reduce the risk of accidents and injury or death: If you are planning on driving the machine on a local highway, be sure to follow all local highway and transport laws and regulations. This may include, but is not necessarily limited to, making sure the SMV (Slow Moving Vehicle) emblem and all the lights and reflectors that are required by the local highway and transport authorities are in place, are clean, and can be seen by all overtaking and oncoming traffic. This machine has three wheeled drive and is designed to handle most farmyard conditions, including driving up or down steep inclines. Please ensure that when driving up or down inclines, the machine faces straight up or down, and not across the incline (as turnover could occur). Be especially careful when traveling up and down inclines with a full load. When traveling up an incline with a full load, it is recommended that the operator disengage the auger to avoid the possibility of engine stalling and loss of control. Likewise, never park the machine on a hill or slope. Only park on flat, level surfaces with blocks applied (or parking brake engaged if equipped). Before driving into an area with low headroom, make sure that you the operator, and the machine fit comfortably. Do not enter if it is not comfortable. When entering into a new area blindly (i.e. from daylight into a dark barn or around a blind corner), decrease to a very slow speed and be prepared to stop suddenly if necessary. Never assume that others are aware of your presence. Jaylor Operating and Maintenance Manual - 28 - A50 Series Models
Warning: Warning: Warning: Do not allow an incompetent person or a person under the age of 16 to operate this machine as they could be injured or killed. The forward and reverse pedals are very reactive. Depressing, releasing or changing direction rapidly may cause loss of control and damage of the machine, and/or injury or death of the operator and/or bystanders. Do not spin tires, especially when driving up and down hills, as control of the machine maybe lost, and/or the operator and/or bystanders could be injured or killed. Warning: A loaded machine (machine and payload) may weigh as much as 2,500 lbs (1134 kg). An operator must use his own discretion when negotiating rough and uneven terrain. Improper operation of the loaded machine can cause loss of control, severe injury, or death. 17. TRANSPORTING The A50 TRAILER MODEL is designed to be easily and conveniently moved from one location to another. The following outlines the procedure for securing and transporting this model. Think SAFETY! Work SAFELY! 1. Always comply with the rules and regulations governing the transporting of agricultural equipment on highways before starting. 2. Make sure all bystanders are clear of the machine and that there are no riders on the machine. 3. Be sure that the towing vehicle is rated to haul the trailer at full load. Remember, the loaded trailer can weigh as much as 2500 lbs (1134 kg). 4. Make sure that the unit is hitched properly to the towing vehicle. This mixer uses a standard 2 inch ball coupler to secure the trailer to the towing vehicle. To couple, move the lever to the opened/unsecured position as shown in Figure 16 below. With the mixer drum empty, drop the trailer coupler over the towing vehicle ball making sure that the coupler slides completely down over the ball. Next, move the lever to the closed/secured position as shown in Figure 16 below. Insert a pin or pad lock completely through the lever in the location shown in Figure 16. If using a pad lock, make sure it is locked and secure. If using a pin, be sure that it is of the type that cannot slip out during transportation (i.e. cotter pin). Check that the trailer coupler and towing vehicle ball are secured by pulling up on the coupler. If it is possible to pull the trailer coupler up, off the towing vehicle ball (with mixer drum empty), then the coupler and ball are not secured. If this is the case, please repeat the steps, making sure that the towing vehicle ball and the trailer coupler are secured. If the connection is either too tight or too loose, see the Trailer Coupler Maintenance section in this manual. NOTE - Some jurisdictions may require a safety chain for this size of machine (not included). Please follow all local highway and transport laws and regulations. Warning: Always be sure that the trailer coupler and towing vehicle ball are of the same size and specification. Failure to do this may cause injury or death to the operator and serious damage to the mixer and/or towing vehicle. Jaylor Operating and Maintenance Manual - 29 - A50 Series Models

The A50 TRUCK MOUNTED MODEL is designed to be mounted easily on a flatbed truck for transportation. Think SAFETY! Work SAFELY! 1. Be sure all bystanders are clear of the machine and that there are no riders on the machine. 2. Lift the mixer onto the truck s flat bed using a forklift with sufficient capacity for the job. Open the forks so that they are just inside the wood skids to maintain stability when lifting. Be sure to run the forks under the mixer frame from the door side (see Figure 18). The mixer should be placed near the driver side edge of the flatbed to insure that the feed will discharge onto the ground beside the truck. NOTE - The loaded mixer can weigh up to 2500 lbs (1134 kg). Be sure that the truck has sufficient capacity to carry this load on the bed safely with the load off center. 3. Secure the tie-down brackets (see Figure 18) to the truck frame or bed using a tie-down chain or strap with sufficient capacity for the job. 4. Be sure that the control pendant and cable is secured. 5. Never transport faster than the road or terrain conditions will allow you to do safely. Figure 18 - A50 Truck Mounted Model Tie-Down Bracket Locations 1. Tie-Down Brackets Secure tightly all four brackets to the truck frame or bed. Jaylor Operating and Maintenance Manual - 31 - A50 Series Models
18. CUTTING AND MIXING The operation of the Jaylor mixer will differ greatly with the various feeds and climatic conditions. In most instances, trial and error is the best method of setting the machine up for a particular commodity to obtain maximum performance. However, as a general rule the lightest commodities should be added first followed by the next lightest commodity and so on. When loading, have the auger turning and try to distribute the commodities evenly within the mixing drum. Once the hays/straws are partially cut and broken apart, other commodities can be added. Remember, additional cutting will take place during mixing, so be careful not to over cut. In some case, where the hays/straws are very long, it has been found beneficial to first add some heavier commodities to eliminate the possibility of the hays/straws wrapping around the auger. Also, when adding hays and straws be careful to only add bales or partial bales that are small enough to fit between the auger periphery and the drum wall. Failure to do so can cause plugging or decreased cutting ability. The type of mix required varies from one operation to another. Therefore, mixing times and procedures will vary as well. Typically, a total mixed ration is achieved in 3 to 5 minutes beginning after the last ingredient is added. When adding ingredients, watch the numbers on the scale indicator to monitor the weight of each ingredient as it is added. We highly recommend the use of a feed nutritionist when planning the rations as well as the regular use of a particle separator to ensure accuracy of mix. For your convenience, a Jaylor Particle Separator, based on the Penn State Particle Separator, is available from Jaylor. Upon completion, the ideal mix will be light, fluffy and uniform. Hays/straws will be cut cleanly at short lengths and no clumping of feed will be visible. Danger: Danger: Danger: Warning: Warning: Never enter the mixing chamber unless the mixer is parked on a flat, level surface, all controls are in neutral, parking brake is applied if equipped (if not, block wheels), engine is stopped, ignition key is removed, and all moving parts have stopped. Also, disconnect the spark plug lead and ground it to ensure the engine does not start unexpectedly. Failure to follow these safety precautions can result in serious injury or death. Never stand on the mixer platform while the drum is being loaded. Stay out of reach of the loading equipment. Never park or load the mixer in a location where you or any person could fall into the mixing chamber as severe injury or death could result. While loading the machine, be certain that no bucket or loading device comes into contact with the rotating auger inside the mixing chamber. This may cause injury or death to the operator and serious damage to the mixer and/or loader. Never load an unhitched machine (A50 trailer model). The machine is designed to be loaded only when properly hitched. Improper loading can cause loss of control, severe injury, or death. Jaylor Operating and Maintenance Manual - 32 - A50 Series Models
Caution: Caution: It is recommended that commodities are added to the mixing chamber while the auger is turning for maximum mix efficiency. Starting the augers from a standstill with a full load in the mixing chamber places additional stress on the machine and may decrease mix quality. Never load anything into the mixing chamber that could cause damage to the machine (i.e. lumber, stones, tires, etc.). The following are some problems that the operator may be faced with at some point during cutting and mixing. Please follow the recommendations given to remedy the problem. Think SAFETY! Work SAFELY! 1. Unplugging: Although plugging or clogging of material can occur in several ways, the main way that plugging or clogging usually occurs is at the unloading door. Always park the mixer on a flat, level surface, put controls in neutral, apply parking brake if equipped (if not, block wheels), stop engine, remove ignition key, wait for all moving parts to stop, (disconnect the spark plug lead and ground it to ensure the engine does not start unexpectedly) before unplugging. Open discharge door and clean out the clogged area. 2. Entangled Material: Twine, string, and wrapping material that is not removed from bales can get tangled in the auger or under the auger. If this material is not removed from the auger, it can cause damage to mixer components as well as decreased mixing and cutting ability. Always park the mixer on a flat, level surface, put controls in neutral, apply parking brake if equipped (if not, block wheels), stop engine, remove ignition key, wait for all moving parts to stop, disconnect the spark plug lead and ground it (to ensure the engine does not start unexpectedly) before removing entangled material. Open the discharge door and remove the entangled material. Jaylor Operating and Maintenance Manual - 33 - A50 Series Models
19. GENERAL FIELD OPERATION The following is a procedure for the general field operation of the A50 mixer.

Be sure that all controls are in neutral and that wheels are blocked (or parking brake is engaged if equipped). 6. Remove wheel blocks or disengage parking brake if equipped. 7. Transport the machine to the feed loading area following guidelines as described in sections 16. Driving and 17. Transporting. 8. Turn auger on as outlined in section 15. Controls. 9. Proceed with loading and mixing of the ration as outlined in section 18. Cutting and Mixing. Danger: Danger: Never stand on the mixer platform while the drum is being loaded. Stay out of reach of the loading equipment. Never enter the mixing chamber unless the mixer is parked on a flat, level surface, all controls are in neutral, parking brake is applied if equipped (if not, block wheels), engine is stopped, ignition key is removed, all moving parts have stopped, and the spark plug lead has been disconnected and grounded (to ensure the engine does not start unexpectedly). Failure to follow these safety precautions can result in serious injury or death. Figure 19 - Total Mix Ration (TMR) Achieved in Mixing Chamber Jaylor Operating and Maintenance Manual - 34 - A50 Series Models
10. Transport the machine to the feeding area. NOTE - It is not recommended that the unit be transported for long distances when the mixing chamber is fully loaded. Transporting will compact the mixture and can make startup difficult. 11. Use a combination of the opening of the unloading door and ground speed to distribute the feed mixture to the desired areas. Follow this order: - Raise the unloading door; - If not already done, start auger rotation; - Begin driving along feeding area to unload the feed. 12. Monitor scale indicator readings to evaluate ration distribution to unloading areas. 13. Continue unloading until mixing chamber is empty or desired amount of mixed ration has been unloaded. Important: It may be necessary, in order to completely empty the mixer of all commodities, to turn the auger on and off rapidly. This will dislodge the feed that is resting on the auger flighting, and allow the auger to unload the feed. 14. Stopping: a. Stop forward motion. b. Close unloading door. c. Slow engine to low idle. d. Turn auger off as outlined in section 15. Controls. e. Stop engine if required. 15. Emergency Stopping: If an emergency should arise, turn auger off, stop forward motion and stop engine immediately. Jaylor Operating and Maintenance Manual - 35 - A50 Series Models

30. HYDRAULIC SYSTEM MAINTENANCE Refer to section 28. Fluids and Lubricants for the recommended oil to use in the hydraulic system your A50 model. Use section 36. Maintenance and Service Record to keep a record of all scheduled servicing. All A50 models are equipped with a hydraulic system with reservoir. Check the reservoir oil level daily. Check for oil leaks every 8 hours or whenever the oil level drops rapidly. Inspect the oil condition for cloudiness and/or impurities. To maintain the hydraulic system, use the following procedures: 1. Clear the area of bystanders, especially small children. 2. Park the mixer on a flat, level surface, put controls in neutral, apply parking brake if equipped (if not, block wheels), stop engine, remove ignition key, and wait for all moving parts to stop. Also, be sure to let engine and hydraulic system cool to a safe temperature before servicing, adjusting or repairing any of these components. Disconnect the spark plug lead and ground it to ensure the engine does not start unexpectedly. 30.1 Checking Level in Hydraulic Oil Reservoir Each hydraulic system is equipped with an oil reservoir and breather/filter cap mounted on the end of the mixer under frame. The oil level must be checked daily when the oil is cool and machine is level. Add oil through the vented cap as required to maintain the oil level between the grooves as identified on the reservoir dipstick (see Figure 29). Figure 29 Hydraulic System Oil Reservoir 1. Breather Cap and Dipstick 2. Maximum Level Groove - Indicates the maximum hydraulic oil level in the reservoir. 3. Minimum Level Groove - Indicates the minimum hydraulic oil level in the reservoir. 4. Hydraulic Oil Reservoir Jaylor Operating and Maintenance Manual - 47 - A50 Series Models
Important: If it is necessary to add oil frequently to maintain the required oil level, there is a leak in the system. Determine the source of the leak and correct before continuing to operate the machine. Contact your Jaylor Dealer or Distributor should you require assistance. 30.2 Replacing Hydraulic Oil and Hydraulic Oil Filter The hydraulic oil must be replaced YEARLY (or sooner if the oil quality has degraded). At this time, the hydraulic oil filter should also be changed. To complete this procedure, follow these steps: a. To drain the majority of the oil from the reservoir, the suction line will have to be disconnected from the reservoir suction fitting (see Figure 30). If it is too difficult to complete this task with the mixer on the ground, it will have to be set higher on stands or blocks (with sufficient stability and capacity to hold the mixer safely). Be sure to use a lifting or jacking apparatus with sufficient capacity for the job to raise the mixer off the ground. b. Place a large oil pan or pail beneath the suction fitting. Remember, the reservoir holds approximately 8.5 US gallons (32 liters) so a container of sufficient size should be used. Remove the suction line and begin draining the reservoir oil. c. Once the oil stops draining from the port, reconnect the suction line to the oil reservoir. Figure 30 Hydraulic Oil Reservoir Hose and Fitting Locations for Drain and Refill 1. Suction Hose 2. Band Clamp 3. Hydraulic Oil Reservoir 4. Breather/Filter Cap and Dipstick NOTE Some hydraulic fittings and hoses in this figure have been removed for clarity. Jaylor Operating and Maintenance Manual - 48 - A50 Series Models
d. Dispose of the used oil in an environmentally safe manner. e. Clean and remove the breather/filter cap as outlined in section 30.3 Maintaining the Breather/Filter Assembly. f. Fill the reservoir with qualified oil. Be sure to fill to the height specified in Figure 29. Remember, the reservoir holds approximately 8.5 US gallons (32 liters). NOTE If your mixer is equipped with a ball valve on the suction line, drain the oil reservoir through the ball valve. Figure 31 Hydraulic Oil Filter Location on A50 Self Propelled Models 1.

30.3 Maintaining Breather/Filter Assembly Each A50 hydraulic oil reservoir is designed with a breather/filter cap on the top to vent the internal system pressure to atmosphere. It must be kept clean and free of contaminants and debris to function properly. Remove any debris that falls on or near the breather to make sure it can still vent. Remove and clean every 200 HOURS of operation, TWICE YEARLY, or if the hydraulic system develops a leak. To maintain the breather, follow this procedure: a. Visually check the breather every day. Remove any material that falls on top of the breather cap and hydraulic oil reservoir. Keep clean and clear to allow for free flow of air for venting the internal system pressure to atmosphere. Important: Oil is added to the hydraulic system through the breather cap port. Always clean around the breather cap prior to removing it and adding oil. b. Clean the breather every 200 hours of operation, twice annually, or whenever the hydraulic system develops a leak. i. Clean the top of the hydraulic oil reservoir. ii. iii. iv. Remove breather cap. Remove any buildup in the breather passages (on the underside of the cap) and clean using a mild detergent and water. Allow breather passages to dry before reinstalling. v. Reassemble and install in reservoir. Important: When spraying water to clean the mixer, protect the breather and reservoir to avoid contamination. 31. ENGINE OR ELECTRIC MOTOR MAINTENANCE All A50 models are supplied with an onboard power source (internal combustion engine or electric motor). Please see the maintenance manual supplied by the power equipment manufacturer for maintenance information and schedules. Jaylor Operating and Maintenance Manual - 51 - A50 Series Models
32. AUGER MAINTENANCE Every Jaylor mixer is designed with a vertical auger that is equipped with knives for cutting material. 32.1 Knife Maintenance To maintain knives, follow this procedure: 1. Clear the area of bystanders, especially small children. 2. Park mixer on a flat, level surface, put controls in neutral, apply parking brake if equipped (if not, block wheels), stop engine, remove ignition key, and wait for all moving parts to stop before servicing, adjusting, repairing or unplugging. Disconnect the spark plug lead and ground it to ensure the engine does not start unexpectedly. 3. Install new knives and tighten mounting bolts to their specified torque. Important: Ensure that no extra hardware and/or tools are left inside the mixing chamber after servicing. 4. Keep knives in good condition. Replace if chipped, dull, or damaged in any way. 5. Knife sharpening is not recommended. Each knife has hardened surfaces on the upper side that keep it sharp. Operating Hint: Below is the recommended initial knife setup for the A50 auger. This setup has proven to work well for a variety of feed rations. The reasoning is as follows: if the knives are setup with too much aggression, feed will have a tendency to move in a circular motion around the drum and jamming will occur. If the knives are setup with too little aggression, then cutting speed will be too slow. Please note that due to the wide variety of feeds and climatic conditions, this setup may not be ideal for some operators. Because of this, some trial and error may be necessary when determining the ideal aggression of the knives. Jaylor Operating and Maintenance Manual - 52 - A50 Series Models
Figure 33 - A50 Recommended Auger Knife Setup 1. Lowest Flat Cutting Knife - This knife should be setup slightly more aggressively than the rest of the flat knives. As shown above, the back tooth should sit 1-1/2 inches (38 mm) out from the edge of the auger flight. The knife is slotted to allow for inward and outward adjustment. 2. Remaining Flat Cutting Knives - These nine knives should not be setup as aggressively as the lowest flat knife. As shown above, the back tooth on all six knives should sit 1-1/4 inches (32 mm) out from the edge of the auger flight. The knives are slotted to allow for inward and outward adjustment. 3. Cutting Angling Blade This blade has the dual purpose of cutting material and pulling feed in towards the center of the auger. Four screws hold this knife in place and there is no adjustment for this knife. Jaylor Operating and Maintenance Manual - 53 - A50 Series Models
32.2 Auger Height Adjustment The auger height is controlled by rotating a bolt under the auger cap (see Figure 34). It is important that the leading edge of the auger does not come into contact with the drum floor during operation. However, it is also important that the leading edge is not too far above the floor. The height will be set at the factory but should be checked occasionally. When measuring this height, rotate the auger one full revolution and find the location where the drum floor and the auger leading edge are closest. At this location, the drum floor and the auger leading edge should be spaced between 1/8 inches (3 mm) and 1/4 inches (6 mm) vertically. Figure 34 A50 Auger Height Adjustment 1. Auger Height Adjustment Bolt Rotate the bolt clockwise to raise the height of the auger and counterclockwise to lower it. 2. Auger Cap 3. Auger Cap Hardware 33. TIRE AIR PRESSURE Inflate tires on all Jaylor A50 models to the manufacturer s recommended pressure. The inflation pressure will be on the tire. Ensure all tires are at the recommended pressure.

34. STEERING CHAIN MAINTENANCE (A50 SELF PROPELLED MODELS) It may be necessary to occasionally tighten the steering chain if it becomes too loose. To tighten the chain, see Figure 35 below. Figure 35 A50 Self Propelled Steering Chain Adjustment 1. Steering Handle Bolts These bolts must be loosened before the chain can be tightened. Once the chain has been tightened, these bolts should be retightened to their original torque. 2. Steering Handle and Column Once the bolts are loosened push the steering column in the direction indicated above until chain is tight. Hold the steering column in place and retighten the bolts. 3. Steering Chain NOTE After retightening the chain multiple times, it may be necessary to shorten the chain. If this is the case, remove the chain, take out the connecting link and cut out the required number of chain links. Then, reinstall the connecting link and mount the chain back in place. Follow the steps above to tighten the chain. Jaylor Operating and Maintenance Manual - 55 - A50 Series Models
35. TRAILER COUPLER MAINTENANCE (A50 TRAILER MODELS) When connecting your trailer to the towing vehicle, it is important that the hitch coupler is adjusted with the correct amount of tension for both smooth and safe trailer performance. A loose connection may cause the coupler to disconnect or to rattle. Likewise, an over-tight lever coupler will make it difficult to connect and disconnect. This can also transmit unnecessary vibration to the towing vehicle. If it is necessary to adjust the trailer coupler so that it mounts securely to the towing vehicle hitch ball, please follow the steps below (also use Figure 36 as a reference): 1. Release the hitch coupler locking lever (to its straight up position). 2. Locate the adjustment nut on the bottom of the hitch coupler. 3. Rotate the nut on the threaded shaft clockwise to increase tightness and counter clockwise to decrease tightness. 4. Remount the trailer coupler on the hitch ball. 5. Push down the hitch coupler-locking lever to its horizontal locking position. 6. Repeat steps 1 through 5 until a snug fit is obtained. Figure 36 A50 Trailer Coupler Maintenance 1.
