OPERATION
CHECK HYDRAULIC POWER
SOURCE
1.Using a calibrated flowmeter and pressure gauge, check that the hydraulic power source develops a flow of
2.Make certain the hydraulic power source is equipped with a relief valve set to a max of 2500 psi/172 bar.
3.Check that the hydraulic circuit matches the tool for opencenter (OC) operation.
CHECK TOOL
1.Make sure all tool accessories are correctly installed. Failure to install tool accessories properly can result in damage to the tool or personal injury.
2.There should be no signs of leaks.
3.The tool should be clean, with all fittings and fasteners tight.
CHECK TRIGGER MECHANISM
1.Check that the trigger operates smoothly and is free to travel between the "ON" and "OFF" positions.
CONNECT HOSES
1.Wipe all hose couplers with a clean
2.Connect the hoses from the hydraulic power source to the hose couplers on the Spike Puller. It is a good prac- tice to connect the return hose first and disconnect it last to minimize or avoid trapped pressure within the system.
3.Observe flow indicators stamped on hose couplers to be sure that oil will flow in the proper direction. The fe- male coupler is the inlet coupler.
NOTE:
The pressure increase in uncoupled hoses left in the sun may result in making them difficult to connect. When possible, connect the free ends of operating hoses together.
OPERATING PROCEDURES
1.Observe all safety precautions.
2.Move the hydraulic circuit control valve to the ON position.
3.Place the spike puller firmly over the spike to be pulled making sure the end of the chute is in full contact with the spike plate.
SPL31A
1.The SPL31A has an automatic pull cycle that engages the spike and sets the tool to the rail at a slow speed; then fully removes the spike at a higher speed, the cycle is automatic, and operates by fully depressing the trigger.
2.At the top of the stroke release the trigger and the spike will automatically be ejected from the puller.
COLD WEATHER OPERATION
If the spike puller is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the nor- mally recommended fluids, fluid temperature should be at or above 50° F/ 10° C (400 ssu/82 centistokes) before use.
