Stanley Black & Decker TA54 User Manual

Tool does not run.

Power unit not functioning.

Check power unit for proper flow 

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 flow 

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-filling 

operations (P/N 01849).

Tool operates slow.

Low oil flow from power unit.

Check power source for proper flow.

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 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.

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 flow and pressure as listed in the table. Use a flowmeter known to be accurate. Check the flow with 

the hydraulic fluid temperature at least 80 °F/27 °C.
