Troubleshooting - Stanley CS11 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 saw, always make sure the hydraulic power source is supplying the correct
hydraulic flow and pressure to the saw as listed in the table. Use a flow meter know to be accurate. Check the flow
with the hydraulic fluid temperature at least 80 °F/27 °C.
PROBLEM
Cuts slow.
Bar turns color.
Tool does not run.
Tool runs backwards.
On/Off trigger is hard to press.
Oil leakage around drive
sprocket.
Oil leakage between rear gear
housing and valve handle
assembly.
Chain continues to move after
valve is shut off.

TROUBLESHOOTING

CAUSE
Insufficient fluid flow or low relief
valve setting.
Chain dull.
Backpressure too high.
Insufficient oiler flow.
Power unit not functioning.
Coupler or hoses blocked.
Mechanical failure.
Pressure and return reversed.
Pressure and return reversed.
Backpressure too high.
Motor shaft seal failure.
Motor face seal failure.
Chain is too loose.
Input flow too high.
REMEDY
Adjust fluid flow to proper gpm. For
optimum performance adjust relief valve to
2250 psi/155 psi.
Sharpen per instructions or replace.
Should not exceed 250 psi/17 bar at 14
gpm/53 lpm measured at the end of the
tool operating hoses.
Use manual oiler during heavy cuts.
Adjust oiler per service instructions.
Check power unit for proper flow and
pressure (10 gpm/38 lpm at 1500 psi/104
bar minimum).
Remove obstruction.
Disassemble tool and inspect for damage.
Connect for proper flow direction. Motor
shaft rotates clockwise.
Correct for proper flow direction.
Should not exceed 250 psi/17 bar at 14
gpm/53 lpm measured at the end of the
tool operating hoses.
Replace as required. Make sure that oil
present is not the result of excess oiler
flow.
Replace as required.
Tighten chain.
Decrease flow.
