PROBLEM CAUSE REMEDY
Tool does not run. Power unit not functioning. Check power source for proper ow
and pressure (7–9 gpm/ 26–34 lpm,
2000 psi/ 140 bar) or 5–6 gpm /18–22
lpm at 1500–2000 psi /105–140 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 of piston or
automatic valve.
Disassemble breaker and inspect for
damaged parts.
Tool does not hit effectively. Power unit not functioning. Check power source for proper ow
and pressure (7–9 gpm/ 26–34 lpm,
2000 psi/ 140 bar) or 5–6 gpm /18–22
lpm at 1500–2000 psi /105–140 bar.
Couplers or hoses blocked. Remove restriction.
Low accumulator charge (pressure
hose will pulse more than normal).
Recharge accumulator. Replace
diaphragm if charge loss continues.
Fluid too hot (above 140 °F/60 °C). Provide cooler to maintain proper uid
temperature (130 °F/55 °C).
Tool operates slow. Low gpm supply from power unit. Check power source for proper ow
and pressure (7–9 gpm/ 26–34 lpm,
2000 psi/ 140 bar) or 5–6 gpm /18–22
lpm at 1500–2000 psi /105–140 bar.
High back-pressure. Check hydraulic system for excessive
back-pressure (over 200 psi/14 bar).
Couplers or hoses blocked. Remove restriction.
Orice plug blocked. Remove restriction.
Fluid too hot (above 140 °F/60 °C) or
too cold (below 60 °F/16 °C).
Check power unit for proper uid
temperature. Bypass cooler to warm
the uid or provide cooler to maintain
proper temperature.
Relief valve set too low. Adjust relief valve to 2100–2250
psi/145–155 bar.
Collar support not sliding freely in the
foot bore (Easi-Ride™).
Remove, clean and replace as required.
Tool gets hot. Hot uid going through tool. Check power unit. Be sure ow rate
is not too high causing part of the
uid to go through the relief valve.
Provide cooler to maintain proper uid
temperature (140 °F/60 °C max). Check
the relief valve setting. Eliminate ow
control devices.
Fluid leakage on tool bit. Lower piston seal failure. Replace seal.
Fluid leakage around
trigger.
Valve spool seal failure. Replace seals.
