Troubleshooting - Stanley TA54 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 tool, always make sure the hydraulic power source is supplying the
correct hydraulic flow and pressure as listed in the table. Use a flow meter known to be accurate. Check the flow
with the hydraulic fluid temperature at least 80 °F/27 °C.
SYMPTOM
Tool does not run.
Tool does not compact effectively. Power unit not functioning.
Tool operates slow.
Tamper gets hot.

TROUBLESHOOTING

CAUSE
Power unit not functioning.
Couplers or hoses blocked.
Pressure and return line hoses
reversed at ports.
Mechanical failure.
Back-pressure too high.
Couplers or hoses blocked.
Back-pressure too high.
Fluid too hot (above 140 °F/60 °C)
Fluid too cold (below
60 °F/15.5 °C).
Tamper shoe too large for soil
conditions.
Low oil flow from power unit.
High back-pressure.
Couplers or hoses blocked.
Fluid too hot (above 140 °F/60 °C)
Fluid too cold (below
60 °F/15.5 °C).
Hot oil going through tool.
SOLUTION
Check power unit for proper flow
and pressure (3–9 gpm/11–34 lpm at
1000–2000 psi/70–140 bar).
Remove restriction.
Be sure hoses are connected to their
proper ports.
Have inspected and repaired by an
authorized STANLEY dealer.
Check hydraulic system for excessive
back-pressure over 250 psi/17
bar measure at the end of the tool
operating hose.
Check power unit for proper flow
and pressure (3–9 gpm/11–34 lpm at
1000–2000 psi/70–140 bar).
Remove restriction.
Check hydraulic system for excessive
back-pressure over 250 psi/17
bar measure at the end of the tool
operating hose.
Provide cooler to maintain proper oil
temperature. Bypass cooler to warm
up oil or provide cooler to maintain
proper temperature.
Use smaller shoe for back-filling
operations (P/N 01849).
Check power source for proper flow.
Check hydraulic system for excessive
back-pressure and correct as required.
Remove restrictions.
Provide cooler to maintain proper oil
temperature. Bypass cooler to warm
up oil or provide cooler to maintain
proper temperature.
Check power unit. Be sure flow 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 flow control devices. Do not
exceed recommended flow.
