3 1.0 INTRODUCTION 1.1 General Information This manual presents removal, operation, and maintenance information for PortaCo s model LR lock remover. The lock remover is designed to remove the safe lock clips from the rail. This tool will help eliminate the use of other methods that increase the likely hood of injury. When properly used this tool will help reduce back strain and also reduce operator fatigue. PortaCo, Inc. reserves the right to make changes at anytime without notice and without incurring any obligation. 1.2 Features The main features of the PortaCo lock remover are as follows. Standard unit: Length in/31.1 cm Width in/25.4 cm Height in/92.0 cm Weight (Dry) 38-lbs/17.2 kg With optional wheel kit: Length in/40.6 cm Width in/38.7 cm Height in/92.0 cm Weight (Dry) 46-lbs/20.8 kg The lock remover is operated from a T style handle. On the T style handle there is a trigger that is used to operate the lock remover. When the trigger is drawn to the handle the trigger link then pushes down on an on/off valve. The on/off valve activates the cylinder that the end ram is attached to. When the end ram moves forward it pulls the grippers along the gripper frame, which will then cause the grippers to clamp around the safe lock clip and pull it off the anchor. After the cylinder has completely extended, release the trigger. When the trigger is released the cylinder retracts causing the grippers to open up, and releases the safe lock clip. Simply lift the lock remover vertically off the rail and the safe lock clip will be sitting on the tie. This tool is designed to remove the safe lock clips from the rail. This tool will help eliminate other methods, which may cause back strain or fatigue. 1.3 Options The lock remover may be equipped with the following options after base model purchase K Wheel Kit 1.4 Safety Summary Tool operators and maintenance personnel must always comply with the safety precautions given in this manual and on the stickers and tags attached to the tool and hoses.

Read and understand this manual and any stickers attached to the power unit before operating. Failure to do so could result in personal injury or equipment damage. Check the rules and regulations at your location. The rules may include an employer s work safety program. Regulations may identify hazards such as working around utility supply lines or hazardous slopes. Read and understand any manuals for additional or optional equipment, which maybe shipped with the tool. 1.6 Warning and Caution Statements Warning and Caution statements have been strategically placed throughout the text prior to operating or maintenance procedures, practices, or conditions considered essential for the protection of personnel, equipment, and property. WARNING: HIGHLIGHTS A, ESSENTIAL OPERATING, OR MAINTENANCE PROCEDURE, PRACTICE, CONDITION STATEMENT, ETC WHICH IF NOT STRICTLY OBSERVED, COULD RESULT IN INJURY TO, OR DEATH OF, PERSONNEL OR LONG TERM HEALTH HAZARDS. CAUTION: HIGHLIGHTS AN ESSENTIAL OPERATING OR MAINTENANCE PROCEDURE, PRACTICE, CONDITION STATEMENT, ETC. WHICH IF NOT STRICTLY OBSERVED, COULD RESULT IN DAMAGE TO, OR DESTRUCTION OF, EQUIPMENT OR LOSS OF MISSION EFFECTIVENESS. 1.7 Training Requirements Operator training for the lock remover should consist of information found in this manual. In addition the operator must receive instructions, both verbally and through demonstrations for applications in which the tool is going to be used. The new operator must start in an area without bystanders and use the tool until able to fully operate the tool under the conditions for the work area. 2.0 INSTALLATION INSTRUCTIONS 2.1 Unpacking Instructions Upon receiving your lock remover promptly remove it from the shipping container. Always keep top side of container up. Inspect unit for damage which may have incurred during shipping and report it to carrier for claim. 2.2 Tool Preparations 4

5 The PortaCo G-18D55-53-W power unit is recommended for hydraulic supply. This unit is equipped with two 5-gpm/20 lpm circuits that can be combined for on 10 gpm/40 lpm circuits. If the tool is used in cold weather, preheat the hydraulic fluid by running power source at low engine speed. Fluid temperature should be at or above 50 F/10 C (400-ssu/82 centistroke) before use, when using recommended fluids. Using too thick of fluid may result in tool damage. 2.3 Testing WARNING: NEVER STICK FOREIGN OBJECTS, FINGERS, OR OTHER EXTRMIIES INTO MOVING MECHANISMS. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY LEAD TO SEVERE PERSONAL INJURY OR TOOL DAMAGE. Before operating the lock remover it is important to inspect the gripper for obstructions or damage. The grippers remove the safe lock clip from the anchor, so it is very important that these are working properly. Follow all safety precautions and procedures when inspecting tool. Place lock remover on a flat surface and tilt it backwards 90. After you have done this locate the grippers which are located at the base of the tool. Once you have located the grippers operate the tool while monitoring the grippers movement. When monitoring the grippers you should watch for the following. -When the trigger is draw the end ram extends forward causing the grippers to move along the gripper frame. Be sure that the end ram is moving the grippers along the gripper frame free and easily. Once the cylinder has completely extended release the trigger. -When the trigger is released the cylinder will then retract bringing the end ram backward with the grippers following along gripper frame. What the operator should look for is that the end ram is retracting the grippers easily with no hesitation. CAUTION: WHEN TESTING THE LOCK REMOVER, BE SURE TO FOLLOW ALL SAFETY GUIDELINES. 2.4 Hose Requirements It is not often necessary or advisable to use long hoses. All hoses must have an oil resistant inner surface and an abrasion resistant outer surface. Each hose must have male pipe ends for most application. Longer hoses can be used when necessary, but can affect the operation of the engine due to resistance in the hose. If small diameter or long hoses are used, or if restrictive fittings are connected to the supply and return ports, the pressure required to push the fluid through the system and back to the tank will be higher. This will reduce tool power. 5

6 *Important Oil should always flow from the male coupler through the female coupler. NOTE: The pressure increase in uncoupled hoses left in the sun may make them difficult to connect. When possible after use, connect the free ends of the operating hoses together. HOSE TYPES Hydraulic hose types authorized for use by PortaCo, Inc. is as follows: 1. Labeled and certified nonconductive 2. Wire braided (conductive) 3. Fabric braided (not certified or labeled non-conductive) Hose 1: Listed above is the only hose authorized for use near electrical conductors. Hoses 2 and 3: Listed above are conductive and must never be used near electrical conductors. HOSE PRESSURE RATING The rated working pressure of the hydraulic hose must be at least 175 bar (2500 psi).

10 At the base of this unit there are four pinch area decals. The base of the tool is where all the moving mechanisms are located, and needs to be approached with caution. (Diagram 3.2B) Diagram 3.2B WARNING: ALWAYS KEEP FOREIGN OBJECTS, FINGERS, AND OTHER EXTREMITIES AWAY FROM THIS AREA. On the inside of the handle next to the manifold is a serial # decal. This decal has the serial number as well as the model number of the unit. Each unit has it s own unique serial number. It is important to keep this decal protected and kept legible. The serial number is needed when ordering replacement parts. (Diagram 3.2C) Diagram 3.2C 3.2C There is an orange strip decal located on the end cap of the cylinder. This orange decal shows the operator where the front of the machine is located. Always keep the orange decal pointing towards the rail when operating. (Diagram 3.2D) Diagram 3.2D 3.3 Connecting Hoses Wipe quick couplers with a clean lint free cloth before connecting them. 1. Connect hoses from power source to the tool. It is recommended that you connect the return hoses first and disconnect last to minimize or avoid trapping pressure within the tool. 3.2D 2. When connecting the quick couplers, the flow should run from male coupler to the female coupler. The female coupler on the tool is the inlet. Quick couplers are marked with a flow direction arrow. WARNING: PRESSURIZED FLUID ESCAPING FROM A DAMAGED HOSE CAN PENETRATE THE SKIN AND BE INJECTED IN THE BODY CAUSING INJURY OR DEATH. CAUTION: DO NOT PULL ON HOSES TO DRAG POWER UNIT. NOTE: When possible, connect the free ends of uncoupled hoses to prevent build up in the hoses. The sun can also increase pressure in the hoses and make connecting them difficult. 3.4 Safe Lock Removal 3.2D NOTE: Remove any obstructions on or around anchor pad, or anything that is lodged under the safe lock clip itself, before attempting to remove the safe lock clip. 10

11 1. Place the lock remover squarely over safe lock clip. Be sure the orange decal located at the front of the machine is facing towards the rail. Once you have the lock remover in place, grip the handle firmly with both hands, and draw the trigger to the handle. 2. By drawing the trigger to the handle the jaws will then grab the safe lock and remove it. 3. Once the safe lock clip has been removed release the trigger and lift remover horizontally off the rail. 4. If the jaws do not get a good enough hold of the safe lock the machine will not be able to remove it. The operator should then release the trigger and reposition the lock remover on the safe lock, and try operation again. If the lock remover is still not removing the safe lock clip there is something else wrong. Look to trouble shooting chart on page Wheel Kit 1. The lock remover may be equipped with an optional wheel kit. The wheel kit allows you to move from safe lock clip to safe lock clip without picking the lock remover up off the rail. This will help reduce back strain. CAUTION: BE SURE THE OPERATORS ALWAYS KEEP A FIRM GRIP ON THE HANDLE NO MATTER WHAT THE OPERATION IS. 2. After removing safe lock clip tilt the lock remover forward. By tilting it forward the wheels on the wheel kit will catch onto the rail. This allows the operator to roll the lock remover to the next safe lock clip quickly and easily. NOTE: Be sure to keep the machine tilted forward enough so that the base of the machine clears the safe lock clip. 3. When moving to get to the next safe lock clip, position the lock remover over the safe lock clip. Then tilt the lock remover towards the operator. The lock remover will easily come off the rail onto the next safe lock clip. 3.6 Disconnecting Hoses: 1. Stop the hydraulic power source. 2. Depressurize the system 3. Allow system and hydraulic fluid to cool. 4. Disconnect the supply (pressure) hose to the power source (pressure port) from the tool ( IN port). 5. Disconnect the return (tank) hose to the hydraulic power source (return port) from the tool ( OUT port). 6. To prevent contamination, always install dust caps over the hydraulic ports of the tool when disconnected. 11
