NOTICE IMPORTANT Operating Instructions For TimberPro Machines 1. TO ACTIVATE THE HYDRAULICS, close door and push the ARM SYSTEM switch on the Main Control panel. (if the charge heater is turned on the machine will not function.) 2. DO NOT ENGAGE THE AXLE DIFFERENTIAL LOCK WHILE THE MACHINE IS IN MOTION OR THE WHEELS ARE SPINNING. This is a positive locking system and major damage will be done if the differential lock is engaged while the wheels are turning. 3. Ground speed, Engine RPM, Hydraulic Drive Pressure, Hydraulic Oil Temperature, and the Time and date can be viewed by activating the UP/DOWN buttons on the MDM monitor. 4. To change direction of travel, Push the forward / reverse drive button. Activating the REVERSE STEER switch on the dash panel coordinates the movement of the joystick with the direction of steer. 5. To change from one gear to another, activate the GEAR BOX SHIFT switch on the dash panel. The machine will not shift until it comes to a complete stop. Even when stopped the machine may not shift because the gears are not lined up. Simply activate the steer slightly which will turn the gears enough to mesh. The MDM monitor will tell you if the machine is in HIGH or LOW gear and also if the gears are not meshed properly. YOU WILL NOT BE ABLE TO DRIVE UNTIL HIGH OR LOW GEAR HAS BEEN ACHIEVED. (only on machines equipt with a two speed gearbox) 6. There are 3 positions on the MOTOR SHIFT switch controlling speed and power, a green backlit "TURTLE" position, a middle "RABBIT" position, and a "DOWNHILL" position. In the "TURTLE" position the machine has maximum power but a slow max speed. This positon is best used in severe conditions or for loading machines on trailers. The middle "RABBIT" position will give you the fasted speed but could cause the machine to overspeed and destroy drivetrain components in a steep down hill condition. This mainly used for roading the machine in a empty condtion. The "DOWNHILL" position must be used in downhill conditions where an over-running load can damage the hydraulic system. This will give you a midrange speed. WHEN GOING DOWN A SLOPE, DO NOT LET THE MACHINE REACH MAXIMUM SPEED THEN HIT THE BRAKES OR RELEASE THE DRIVE PEDAL ABRUPTLY WHICH CAN CAUSE THE ENGINE TO OVER-SPEED. This could cause the wheel drive motors to exceed the maximum RPM or an abrupt braking could cause damage to the gearbox or hydraulics. USE THE "DOWNHILL" POSITION FOR SEVERE DOWNHILL CONDITIONS. 7. Grease all pins and the articulation joint daily. See Training and Maintance manual for lubrication points and recomended grease to be used. 8. Check wheel lug nut torque after the first 50 hours of operation. A loose wheel can cause extensive damage to the axle planetary and wheel hub. Torque wheel lug nuts 600 ft.lbs. 9. Grease all driveshaft universal joints every 50 hours of operation. Also check all fluid levels. Very wet or muddy conditions require greasing and fluid inspection more frequently. 10. Check articulation joint bolts, axel mounting bolts, swing bearing and tapered hub bolt torques after the first 50 hours of operation. 11. It is very important to read the Operator Training & Maintenance manual so that the operation and maintenance of the machine is fully understood. The TimberPro T620 Series machines are a good product, but they are only as good as those who operate and maintain them. PN# 51358 Form T044 4.1.3 Machine Operation - General

Operator s Cab The TimberPro operator s cab is one of the strongest cabs in the industry. TimberPro has a great concern for operator safety. TimberPro cabs are destructive tested to ensure they meet or exceed the guidelines set forth for safe operation. TimberPro cabs are certified for ROPS, OPS, & FOPS by the governing boards of SAE (Society of Automotive Engineers) and WCB (Canadian Workers Compensation Board). ROPS - Roll Over Protection System OPS - Operator Protection System FOPS - Falling Object Protection System Three Cab Escape Routes Three escape routes from the cab are provided. See Figure 1. These escape routes are as follows: 1) Cab door - This is the normal exit. 2) Kick-out front window - The complete front window and be removed by loosening six star knobs. 3) Removable rear window - The complete rear window and its frame can be removed by removing four star knobs from either inside or outside the cab. The front and rear cab window exits require a check for proper operation at least once a week. See Section 3.1 of Operation & Maintenance Manual. In addition, the operator should be sure all interior star knobs are not too tight and that he/she is able to remove them prior to beginning the working shift. 3) Rear Cab Window Escape Hatch Note: The rear window escape hatch opens inward 2) Front Cab Window Escape Hatch 1) Cab Door 00867 Figure 1: Operator Cab Emergency Escape Routes Machine Operation - General 4.1.4 Form T044

Automatic Reversing Engine Fan All TimberPro machines are equipped with an automatic reversing engine fan to help keep the radiator and hydraulic oil cooler fins clean. The operation of the automatic reversing engine fan (purge cycle) is controlled by a timer located in a control box mounted behind the cab. (See Figure 2) The timer is factory set to reverse every 32 minutes for 5 seconds. This setting can be changed. (See instructions below) The Fan can also be activated by pressing the reversing fan switch located on the dash panel inside the operators cab. Automatic Reversing Fan Timer Adjustment To adjust the cycle time on the reversing fan timer the Timer Remote Module (#51262) is required.

System Monitoring Gauges The machine is equipped with several gauges to help protect vital systems from damage. All system monitoring gauges (except the voltmeter and wheel drive pump pressure output) are connected to the warning alarm. If a system monitoring gauge reaches its preset warning condition, its red indicator light will blink and the warning alarm will sound to alert the operator. The following is a review of all system monitoring gauges starting from the top of the dash panel. See Figure 1 for each item s location. Disc Saw Pressure Gauge (Optional)(Reference #1, Figure 1) Avoid fast increases in engine throttle when the disc saw is activated. Increase engine throttle slowly so the disc saw pump and motor can keep up with the engine. Too great an increase can cause the disc saw motor to shift into low gear and take longer to reach full speed. The disc saw pressure gauge is used only when a high speed disc saw attachment is installed. The gauge monitors the required pressure output from the machine s dedicated disc saw pump to rotate the cutting disc at a set RPM (See attachment manufacturer s specifications). When the disc saw circuit is first activated the gauge will read about 3600 psig (24,83 Mpa) which is the relief setting of the disc saw pump. At start up the disc saw pump is at full stroke and maximum pressure output to start spinning the cutting disc. As the disc gains speed it builds momentum. Less pressure is required to keep the disc spinning under momentum so the gauge reading will begin to drop. Most disc saws have 2-speed motors. When the motor shifts into high gear the gauge reading will suddenly increase. In high gear the motor s displacement is greater and it takes more pressure to maintain the cutting disc s speed until it can regain momentum. Once the cutting disc reaches full RPM with full momentum, the pressure requirement will drop and the gauge will read normal operating pressure. The whole process from cold start to full RPM takes about 25-30 seconds. When a cut is made it is normal to see a sudden pressure rise as the cutting disc contacts the tree and completes the cut. This means that the disc saw pump is at full stroke to regain cutting disc speed after momentum was lost cutting the tree. Only when the cutting disc is pinned to prevent any rotation will the gauge read a constant 3600 psig (24,83 Mpa). Normal operation:...... 1600-2200 psig.................. (11,03-15,17 Mpa) Warning alarm @:.............. None Gauge readings are affected by anything that is a resistance to the rotation of the cutting disc, such as working RPM, hydraulic oil temperature, cutting disc bearing lubrication, etc. For example; cold hydraulic oil will produce a higher gauge reading which then drops as the oil warms... or a new cutting disc bearing with fresh grease may produce a lower gauge reading that will begin to rise as the grease ages and breaks down. Form T045 4.2.3 Machine Operation - Operator s Dash Panel

Return Filter Back Pressure Gauge (Reference #2, Figure 1) Return filter bypass will allow unfiltered oil into the main tank where it begins contaminating the rest of the hydraulic system. Prevent return filter bypass. Dirty return filters lead to return filter bypass and hydraulic system contamination. Change return filters according to preventative maintenance guidelines, or sooner if required. Incorrect cold weather operating procedures can force return filter bypass. Follow the Machine Warm-Up Procedure as outlined in Section 4.3 of the Operation & Maintenance Manual. The return filter back pressure gauge monitors return oil back pressure above the three in-tank return filters. Normal operation:............ 5-15 PSI....................... (35-105 kpa) Warning alarm @:............. 20 PSI........................... (140 kpa) Return oil back pressure is dependent on hydraulic oil temperature. The return filters will go into bypass when back pressure reaches 29 PSI (200 kpa). Preventing return filter bypass is extremely important. Unfiltered oil bypassing the return filters will enter the main tank and begin to contaminate the entire hydraulic system. Excessive return oil back pressure is the result of dirty return filters or cold oil being forced through the filters. Change return filters according to the preventive maintenance schedule in this manual and always after a major component failure. During cold starts, always allow the machine to reach normal operating temperature before running at full throttle. Following These simple rules will help prevent costly down-time and increase the life of your equipment. Voltmeter (Reference #3, Figure 1) The voltmeter monitors the condition of the machine s electrical charging system. Normal operation:........ In green zone Warning alarm @:.............. None If a low battery charge is indicated, have the batteries and the engine s alternator belts checked. The machine can operate with a low battery charge, but any use of auxiliary electrical equipment, such as the exterior lights, will rapidly drain the batteries. Hydraulic Oil Temperature Gauge (Reference #4, Figure 1) The hydraulic oil temperature gauge monitors the temperature of the hydraulic oil in the tank. Normal operation:........ +100 o F (38 o C).. above ambient (outside air) temperature Warning alarm @:. Varies with ISO rating ISO 32.................. 170 o F (77 o C) ISO 46.................. 190 o F (88 o C) ISO 68.................. 210 o F (99 o C) The gauge is factory set for the ISO rating of the oil shipped in the machine. When changing oil, be sure the gauge is set correctly for the new ISO rating (available from your oil distributor). To adjust the gauge, use a 1/16 hex tool to turn the screw in the center of the gauge face. If high hydraulic oil temperature is a re-occurring problem, check the radiator/oil cooler fins for debris or look for a possible pump or valve relief set too low that is allowing oil to dump over it and creating excessive heat.

Engine Oil Pressure Gauge (Referencce #5, Figure 1) Operating the machine with low engine oil pressure will cause severe damage to the engine. The engine oil pressure gauge monitors engine lubricating oil pressure. Normal operation:............. Varies @ Cold idle............... 70-80 PSI...................... (480-550 kpa) @ Hot idle................ 35-40 PSI...................... (210-275 kpa) @ Hot full throttle.......... 60-70 PSI...................... (415-480 kpa) Engine Water Temperature Gauge (Reference #6 Figure 1) The engine water temperature gauge monitors the engine s cooling system temperature. Normal operation:......... 160 o - 210 o F......................... (70 o - 99 o C) Warning alarm @:............. 210 o F............................. (99 o C) If the engine water temperature gauge sounds an alert, return the engine to an idle until it cools down. If engine overheating is a re-occurring problem, check the radiator/oil cooler fins for debris. Keep the area in front of the radiator/oil cooler clean for maximum cooling air flow. Warning alarm @:............. 20 PSI.......................... (140 kpa) Normal gauge readings will vary with engine temperature. Shut down engine immediately if engine oil pressure drops. Have machine inspected and get the problem corrected before re-starting the engine. Form T045 4.2.5 Machine Operation - Operator s Dash Panel

System Warning Lights Low Hydraulic Oil Level (Reference #7, Figure 1) Low hydraulic oil level can expose suction filters to air and cause catastrophic damage to the pumps. Keep hydraulic oil level in the green zone of the sight gauge at operating temperature. The machine is equipped with a sensor which monitors hydraulic oil level in the tank. The low hydraulic oil level sensor is designed to protect the machine in the event of a hose failure or rapid oil loss. Shut down machine immediately if the low hydraulic oil level warning light signals an alarm. The warning light is RED colored. It is very important that a safe level of oil is maintained in the tank at all times. The operator will be alerted if the oil level in the tank drops below a safe level. Always use the hydraulic oil level sight gauge mounted on the tank to determine a safe oil level. Parking Brake ON (Reference #8, Figure 1) The parking brake ON warning light alerts the operator whenever the parking brake is set. The warning light is RED colored. Charge Oil FIlter Bypass (Reference #9, Figure 1) Preventing charge oil filter bypass is very important. Unfiltered oil bypassing the charge filter will enter the hydrostatic wheel drive circuit and begin to contaminate the loop. Excessive charge oil back pressure is the result of a dirty filter or cold oil being forced through the filter. Change filter according to the preventive maintenance schedule in this manual and always after a major component failure. During cold starts, always allow the machine to reach normal operating temperature before running at full throttle. Following These simple rules will help prevent costly down-time and increase the life of your equipment. The warning light is YELLOW colored. Axle Differential Lock ON (Reference #10, Figure 1) The parking brake ON warning light alerts the operator whenever the parking brake is set. The warning light is YELLOW colored. 00056 Figure 2: Hydraulic Oil Sight Gauge The sight gauge can be seen from the operator s seat. See Figure 2. It is always a good policy for the operator to check oil level frequently throughout the working shift. Machine Operation - Operator s Dash Panel 4.2.6 Form T045

Ignition Key Switch (Reference #23, Figure 1) Engine Throttle Control Fast Slow Throttle Zones 00395 00395 Figure 5: Ignition Key Switch Figure 6: Engine Throttle Control (Reference #24, Figure 1) Keep the ignition key in the RUN position while the engine is running. Do not turn the ignition key to the START position while the engine is running. Damage to the engine could result. OFF - Turn the ignition key the the OFF position to shut down the engine. Insert and remove the ignition key from this position only. See Figure 5. START - Turn the ignition key all the way to the right to crank engine. Release the key when the engine starts. Do not crank the engine for more than 30 seconds. If the engine doesn t start, return the ignition key to the OFF position and wait about 2 minutes before trying again. RUN - The ignition key will automatically return to this position when it is released after the engine starts. Operating the engine above an idle when cold can damage the piston rings and increase wear on all engine parts. Allow the engine to warm-up before operating above an idle. SLOW - Idle position. See Figure 6. Always allow the engine to reach operating temperature before going to work. Return the throttle to this position and let the engine idle for a few moments before shut down. FAST - Full throttle. See Figure 6. After the engine has reached operating temperature, move throttle forward to operate the loader and travel hydraulics. There are two throttle zones; LOADER and TRAVEL. LOADER ZONE - Advance the throttle into the LOADER zone to operate the loader hydraulics. The loader does not require the full horspower output of the engine. Only operate the loader at a maximum of 3/4 throttle. Advancing the throttle further will only waste horsepower and fuel and result in unnecessary engine wear. TRAVEL ZONE - Advance the throttle into the TRAVEL zone when operating the travel hydraulics. Always operate the travel hydraulics in the TRAVEL zone to get maximum horsepower and travel pump output. Form T045 4.2.9 Machine Operation - Operator s Dash Panel

Warning Alarm (Reference #25, Figure 1) The warning alarm is an audible alert for the operator of a potential system problem monitored by gauges and warning indicator lights on the dash panel. Hourmeter (Reference #26, Figure 1) The hourmeter records the actual hours the machine has been operated. Do not disconnect the hourmeter for any reason. All recommended preventive maintenance procedures are based on the hourmeter reading. Reversing Engine Fan Override (Reference #27, Figure 1) Activates the reversing engine fan to blow debris out of the radiator/oil cooler fins. Normally, the reversing engine fan is set to automatically actuate at timed intervals. See section 4.1 in this book for fan timer adjustment and settings.

See Section 2.2 of this manual for additional information. o Understand the importance of keeping the hydraulic oil level in the tank at the correct level. See Section 2.2 of this manual for additional information. o Keep the ignition key in the RUN position while the engine is running. Do not turn the ignition key to the START position while the engine is running. Damage to the engine could result. o Operating the engine above an idle when cold can damage the piston rings and increase wear on all engine parts. Allow the engine to warm-up before operating above an idle. o Keep the throttle control in the LOADER zone when operating the loader. Full engine RPM is not required to run the loader. Operating the loader at full throttle wastes fuel. o Use the pump destroke feature in cold weather to reduce the load on the engine at start-up and to save battery life. o If your fuel consumption is too high, be sure the throttle is kept in the LOADER zone while operating the loader. Operating the loader at full RPM is not necessary and wastes fuel. o If the steering controls are crossed. Check the position of the reverse steer switch. o If the swing function feels spongy or drifts too much during normal loader operation, first check that the swing detent feature is not activated. Only use swing detent when traveling in reverse with the grapple clamped to the rear frame. o If the machine loses top speed, be sure the hydraulic motor shift ON/OFF switch is not activated and locking the travel motors into high displacement, low speed. o If the machine turns hard or the rear bogies try to bounce or chatter through the turn, be sure the axle differential lock is not engaged. o If the engine turns hard or is hard to start in cold weather, use the pump destroke feature to take the load of turning the pumps off the engine. o If the machine is starting hard and is equipped with a Caterpillar enigne, be sure and use the engine air intake heater during engine start-up. o Do not engage the axle differential lock if the wheels are spinning. Damage to the axle could result. Only keep the axle differential lock engaged to negotiate a bad spot on the skid trail. Be sure to disengage the axle differential lock when not needed.

This unit monitors the system and allows the operator to select from four different operational modes, adjust individual function settings and perform basic troubleshooting procedures. See the Basic IQAN Training Manual shipped with the machine for complete MDM operation instructions. Figure 1: MDM (Multiple Display Module) Panel Layout MDM Panel Rocker Switches The MDM panel is equipped with several rocker switches and indicator/warning lights. The following is a review of the rocker switch controls found on the MDM panel. Machine Operation - MDM Panel 4.4.2 Form T061

Forward and Reverse Travel Direction Lights (Optional) (Reference 2&3, Figure 1) The forward and reverse direction lights represent the machine travel direction that is currently chosen. When the drive pedal is depressed the machine will travel in what ever direction is currently illuminated on the travel direction lights. This can be changed by depressing the travel direction switch located next to the drive pedal. Arm System ON (Reference 4, Figure 1) The arm system switch is a momentary switch that signals a relay to supply power to the IQAN digital control system. The system arm switch is part of the safety door interlock circuit so power to the IQAN digital control system is terminated if the cab door is opened or the engine is shut down. When the IQAN system is powered up, a GREEN indicator light in the switch will illuminate. Engine Diagnostics Switch (Reference 5, Figure 1) The engine diagnostics switch is used when there is a suspected problem with the electronic engine. When this switch is turned on it will signal the engine to then start flashing out an error code using the engine warning and engine stop lights also located on this panel. Auto Throttle Switch (Reference 6, Figure 1) The auto throttle switch is used mainly on TS and TF style machines. With this switch in the Auto position when the drive pedal is depressed the engine will automatically speed the engine RPM up to full throttle. When the drive pedal is released the engine RPM will then slowly return to the current throttle joystick setting. When the Auto Throttle switch is placed in the Manual position this feature is disabled. Throttle Direct Switch (Reference 7, Figure 1) The Throttle direct switch is only used for troubleshooting by a certified engine mechanic. When in the switch is in the Manual position the Throttle Joystick signal is fed direct to the engine (this will disable Auto throttle). This switch should be in the IQAN Throttle position at all times. Reverse Steer ON/OFF (Reference 8, Figure 1) Always be aware of the present configuration of the steering controls before moving the machine. Serious personal injury or death could result if the machine makes an unexpected movement because of reversed control settings. RED colored switch used to swap or reverse the steering control inputs when operating the machine in reverse travel. Reverse travel is with the operator facing the clam bunk or floating bunk. See Figure 2. This allows the actual operator steering control inputs to remain the same regardless of machine travel direction. Push down on the left side of switch to move it to the ON position and reverse the steering controls for reverse machine travel. Push down on the right side of switch to move it to the OFF position and return the steering controls to normal for forward machine travel. When Reverse Steer Feature is activated, steering control will be crossed when traveling in the normal forward direction. Form T061 4.4.3 Machine Operation - MDM Panel

Charge Oil Heater ON/OFF (Reference 9, Figure 1) A track drive charge oil heater block is available as an option for helping to speed-up hydraulic system warming in colder climates. It is very important that a safe level of oil is maintained in the tank at all times. The operator will be alerted if the oil level in the tank drops below a safe level. Always use the hydraulic oil level sight gauge mounted on the tank to determine a safe oil level. Push down on the left side of switch to move it to the ON position and actuate the charge oil heater. Push down on the right side of switch to move it to the OFF position and deactivate the charge oil heater. The switch is YELLOW colored. NOTE: The IQAN digital control system is equipped with an interlock to prevent operation of the machine while the charge oil heater is ON. This must be done to prevent damage from system overheating. MDM Panel Indicator Lights The MDM panel is also equipped with several indicator/warning lights. The following is a review of the lights found on the MDM panel. System Armed (Reference 10,Figure 1) This indicator light will be illuminated only when the IQAN system is properly armed. This requires the Ignition to be on, the Door shut and the Arm System switch depressed. Low Hydraulic Oil Level (Reference 11, Figure 1) low hydraulic oil level can expose suction filters to air and cause catastrophic damage to the pumps keep hydraulic oil level in the green zone of the sight gauge at operating temperature. Water In Fuel (Reference 12, Figure 1) This warning light is illuminated when the electronic engine senses that water is present in the fuel filter located on the side of the electronic engine. Wait to Start Figure 3: Hydraulic Oil Sight Gauge (Reference 13, Figure 1) 00056 This indicator light is used only when starting the machine. The electronic engine goes through a series of startup adjustments to prepare the engine for the startup process. The operator need to wait until this light goes off before cranking of the engine can begin. When the outside air temp drops below 30 degrees fahrenheit this light will go off for a second and then will come back on. This is telling you that the intake grid heater is being used and cranking should not begin until the light has again gone out. The machine is equipped with a sensor which monitors hydraulic oil level in the tank. The low hydraulic oil level sensor is designed to protect the machine in the event of a hose failure or rapid oil loss. Shut down machine immediately if the low hydraulic oil level warning light signals an alarm. The warning light is RED colored. Machine Operation - MDM Panel 4.4.4 Form T061

Engine Warning Light (Reference 14, Figure 1) This warning light is used for warning of possible problems with the electronic engine. If this light is illuminated then you should get to a safe place and then shut the machine down. When the machine is shut down, turn the ignition key to the ignition position, turn on the engine diagnostics switch. If there is still a problem the warning and stop engine lights will now start to flash out a three digit engine error code. There will be a brief pause between each digit. When the engine is done flashing out the error code there will be a longer pause. If there is more than one code it will then start flashing out the second code or if just one code is present it will be repeated. Write down the error code and contact a certified engine dealer and they will be able to help you. Stop Engine Light (Reference 15, Figure 1) The Stop engine light is used to warn of a serious problem with your electronic engine. When the stop engine light is illuminated shut down the engine as soon as it is safe to do so. Then follow the procedure for getting the error code as listed under the previous section for the engine warning light. Water in fuel, wait to start,engine warning and engine stop lights should be illuminated for a few seconds prier to starting of electronic engine to insure that the warning bulbs and engine warning system are working properly.
