Good maintenance practices will keep the tool on the
job and increase its service life.
A very important maintenance practice is to keep the
hydraulic fluid clean at all times. Contaminated hydrau-
lic fluid causes rapid wear and/or failure of internal
parts.
Follow the procedures contained in the HYDRAULIC
SYSTEM REQUIREMENTS section of this manual to
ensure peak performance from the tool. Never disas-
semble the tool unless proper troubleshooting proce-
dures have isolated the problem to an internal part.
Then, only disassemble it to the extent necessary to
replace the defective part.
KEEP CONTAMINANTS SUCH AS DIRT AND GRIT AWAY
FROM INTERNAL PARTS AT ALL TIMES.
DO NOT ATTEMPT TO SERVICE THIS TOOL IF YOU
ARE NOT THOROUGHLY TRAINED IN THE PROPER
DISASSEMBLY AND ASSEMBLY OF THIS TOOL.
IMPROPER DISASSEMBLY OR ASSEMBLY MAY
RESULT IN BODILY INJURY AND DAMAGE TO THE
TOOL. ALWAYS REFER ALL MAINTENANCE TO A
QUALIFIED AND TRAINED TECHNICIAN.
Always determine and correct the cause of the problem
prior to reassembly. Further wear and tool failure can
result if the original cause is not corrected.
PRIOR TO DISASSEMBLY
•
Clean the exterior of the tool.
•
Obtain a seal kit to replace all seals exposed during
disassembly. Note the orientation of seals before
removing them. Install new seals in the same
position as original seals.

SERVICE INSTRUCTIONS
2. Swing the latch (61) away from the motor plate (68).
Install the latch removal tool over the retaining ring
(62), spring back-up (63).
3. Use 2 "C" clamps or bar clamps to squeeze the latch
removal tool against the spring so that the spring
back-up and spring are depressed enough to expose
the retaining ring. Pry the retaining ring out.
4. Slowly release the clamps and remove them.
Remove the spring back-up, spring, latch washer
(65), and latch.
LATCH RE-ASSEMBLY
1. Install the latch, latch washer, spring and spring
back-up onto the motor plate with orientation as
shown in the parts drawing.
2. Place the retaining ring in the groove in the latch
removal tool. Install the latch installation tool into
the recessed bore of the latch removal tool. The
retaining ring should now be between the latch
removal tool and the latch installation tool. Place
this assembly over the spring back-up with the
protuding end of the latch installation tool inserted
into the bore of the motor plate.
3. Using a large mallet, strike the face of the latch
removal tool with one swift blow. This should push
the retaining ring into place.
THROTTLE VALVE SERVICE
The throttle valve can be serviced without disassembling
the entire tool. Follow the instructions below.
1. Remove the valve lever (8) by unscrewing the
locknut (7). Lift out the key (47).
