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 supply-
ing the correct hydraulic flow and pressure to the spike
Rod driver does not run.
Rod driver does not hit
effectively.
Rod driver operates slow.
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.
Power unit not functioning.
Couplers or hoses blocked.
Presssure and return line hoses
reversed at ports.
Mechanical failure of piston or
automatic valve.
Power unit not functioning.
Couplers or hose blocked.
Low accumulator charge
(pressure hose will pulse more
than normal).
Fluid too hot
(above 140° F / 60° C).

Provide cooler to maintain proper
fluid temperature.
Remove, clean and replace as
required.
