TROUBLESHOOTING
PROBLEM CAUSE SOLUTION
Drill will not start Power not being supplied.
Check to make certain that both hoses are
connectd.
Turn hydraulic circuit control valve ON.
Defective quick-disconnect.
Check each disconnect separately. Re-
place as neccessary.
Jammed motor and/or parts.
Separate modules and inspect. See
Service Instructions. Do not force parts
together.
Flow reversed through hoses.
Correct the power source control valve
position. Prevent reverse fl ow by using
only one port from the valve for pressure,
the return tool hose to the cooler and the
fi lter line. Correct the quick-disconnect
male/female routing per instructions and
arrows on the fi ttings.
Low hammer impact or drilling torque. Incorrect hydraulic fl ow.
Check that the hydraulic power source is
producing 4-9 gpm / 15-34 lpm at 750-
2000 psi / 53-140 bar.
Defective quick-disconnect. Check each disconnect separately.
Worn impact mechanism.
Separate modules and repair or replace
impact mechanism. See Service Instruc-
tions.
Incorrect grease.
Metabo (forward module) mechanism is
full of fl uid or contaminants or is improp-
erly greased. “Clean out, re-lubricate,
and/or repair per Matabo instructions. See
instructions for separating the rear module
to supply Metabo portion to the dealer for
service”.
Reversing spool incorrectly installed.
Reversing spool upside down. Do not
separate modules. See Service Instruc-
tions.
Hydraulic circuit relilef set too low, hoses
too restrictive or the hydraulic fl uid is too
thick.
Set relief valve at 2100 psi / 145 bar. See
Service Instructions.
Fluid restriction in hose or valve. Excess
back pressure.
Locate and remove restriction.
Use correct fl uid.
Fluid not warmed-up. Preheat system.
Hoses too long for hose ID. Use shorter
hose.
Priority fl ow control valve or reverse check
valve is malfunctioning. Do not separate modules. See Service
Instructions.
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 hammer drill,
always check that the hydraulic power source is supply-
ing the correct hydraulic fl ow and a pressure to the tool as
listed in the table. Use a fl owmeter known to be accurate.
Check the fl ow with the hydraulic fl uid temperature at least
80
