TROUBLESHOOTING

If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem.

When diagnosing faults in operation of the spike puller, always check that the hydraulic power source is supplying the correct hydraulic flow and pressure to the spike driver as listed in the table. Use a flowmeter known to be ac- curate. Check the flow with the hydraulic oil temperature at least 80 °F/27 °C.

NOTICE

In addition to the Safety Precautions found in this manual, observe the following for equipment protection and care.

Always store an idle tool in a clean dry space, safe from damage or pilferage.

Do not exceed the rated limits or use the tool for ap- plications beyond its design capacity.

Always keep critical tool markings, such as labels and warning stickers legible.

Always replace hoses, couplings and other parts with replacement parts recommended by Stanley Hydraulic Tools. Supply hoses must have a mini- mum working pressure rating of 2500 psi/175 bar.

Permit only experienced personnel to perform tool repair.

Be sure to wipe all couplers clean before con­necting. Use only lint-free cloths.

The hydraulic circuit control valve must be in the OFF position when coupling or uncoupling the tool. Failure to do so may result in damage to the quick couplers and cause overheating of the hydraulic system.

Check fastener tightness often and before each use daily.
