SYMPTOM CAUSE SOLUTION
Tool does not run. Power unit not functioning. Check power unit for proper ow
and pressure (3–9 gpm/11–34 lpm at
1000–2000 psi/70–140 bar).
Couplers or hoses blocked. Remove restriction.
Pressure and return line hoses
reversed at ports.
Be sure hoses are connected to their
proper ports.
Mechanical failure. Have inspected and repaired by an
authorized Stanley dealer.
Back-pressure too high. Check hydraulic system for excessive
back-pressure over 250 psi/17
bar measure at the end of the tool
operating hose.
Tool does not compact effectively. Power unit not functioning. Check power unit for proper ow
and pressure (3–9 gpm/11–34 lpm at
1000–2000 psi/70–140 bar).
Couplers or hoses blocked. Remove restriction.
Back-pressure too high. Check hydraulic system for excessive
back-pressure over 250 psi/17
bar measure at the end of the tool
operating hose.
Fluid too hot (above 140 °F/60 °C)
Fluid too cold (below
60 °F/15.5 °C)
Provide cooler to maintain proper oil
temperature. Bypass cooler to warm
up oil or provide cooler to maintain
proper temperature.
Tamper shoe too large for soil
conditions.
Use smaller shoe for back-lling
operations (P/N 01849).
Tool operates slow. Low oil ow from power unit. Check power source for proper ow.
High back-pressure. Check hydraulic system for excessive
back-pressure and correct as required.
Couplers or hoses blocked. Remove restrictions.
Fluid too hot (above 140 °F/60 °C)
Fluid too cold (below
60 °F/15.5 °C)
Provide cooler to maintain proper oil
temperature. Bypass cooler to warm
up oil or provide cooler to maintain
proper temperature.
Tamper gets hot. Hot oil going through tool. Check power unit. Be sure ow rate is
not too high causing excess oil to go
through the relief valve. Provide cooler
to maintain proper oil temperature.
Bypass cooler to warm up oil or
provide cooler to maintain proper
temperature (100–130 °F/38–54 °C).
Eliminate ow control devices. Do not
exceed recommended ow.
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 tool, always make sure the hydraulic power source is supplying the cor-
rect hydraulic ow and pressure as listed in the table. Use a owmeter known to be accurate. Check the ow with
the hydraulic uid temperature at least 80 °F/27 °C.
