Troubleshooting - Stanley SD67 User Manual

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 driver, 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
accurate. Check the flow with the hydraulic oil temperature at least 80 °F/27 °C.
Problem
Spike driver does not run.
Spike driver does not hit
effectively.
Spike driver operates slow.
