Section 4: Maintenance
It is highly recommended to practice regular check-ups and maintenance in accordance with the usage
frequency to keep your tool in better condition and reduces total running costs.
Troubleshooting Guide
If symptoms of poor performance develop, the following chart can be used as a guide to correct the
problem. When diagnosing faults in operation, always check that the hydraulic power source is supplying
the correct hydraulic flow and pressure to the tool as listed in the following table. Use a flow meter known
to be accurate. Check the flow with the hydraulic fluid temperature at least 80
o
F/27
o
C.
Symptom
Cause
Solution
Tie tamper does not run.
Power unit not functioning.
Check power source for proper flow and
pressure, 4-6 GPM/14-23 LPM, 1500-
2000 psi/106-140 bar. TT46233 Model, 7-
10 GPM/26-38 LPM.
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 of piston or
automatic valve.
Disassemble tamper and inspect for
damaged parts.
Tie tamper does not run
effectively.
Power unit not functioning.
Check power source for proper flow and
pressure, 4-6 GPM/14-23 LPM, 1500-
2000 psi/106-140 bar. TT46233 Model, 7-
10 GPM/26-38 LPM.
Couplers or hoses blocked.
Remove restriction.
Low accumulator charge (pressure
hoses will pulse more than normal).
Recharge accumulator. Replace
diaphragm if charge loss continues.
Oil too hot (above 140°F/60°C).
Provide cooler to maintain proper oil
temperature (140°F/60°C).
Tie tamper operates slow.
Low GPM supply from power unit.
Check power source for proper flow and
pressure, 4-6 GPM/14-23 LPM, 1500-
2000 psi/106-140 bar. TT46233 Model, 7-
10 GPM/26-38 LPM.
High back-pressure.
Check hydraulic system for excessive
back-pressure (over 200 psi/14 bar).
