H8508 Hydraulic Impact Wrench
Maintenance Schedule
The service life of the tool will be maximized by proper
care and maintenance. The maintenance schedule
below is recommended.
H8508 Impact Wrench
Daily:
1.
Wipe all tool surfaces clean of grease, dirt and
foreign material.
2.
Inspect the hydraulic system hoses and fittings for
signs of leaks, cracks, wear, or damage. Replace if
necessary.
3.
To prevent contamination, always install dust caps
over the hydraulic ports when disconnected.
Monthly:
•
Perform a detailed inspection of the system hoses
and fittings as stated in Appendix A - S.A.E. Stan-
dard J1273, May 1986. Replace the hoses and/or
fittings if necessary.
Quarterly:
•
Remove the hammer case cap, anvil, impact
mechanism assembly, spacer, washers and thrust
bearing. Clean the grease from the inside of the
handle cavity and all impact components. Apply a
coat of grease (Mobile Grease HP) to thrust
washers (48319), thrust bearing (48318), hammers
(48345), hammer pins (48346) and anvil (48347) or
(48397). Pack the hammer frame center space
before pushing the anvil into the grease pocket.
Reassemble components and tighten hammer case
cap (48516) securely. If wrench is used under
severe operating conditions or hard-duty cycle,
mechanism may need to be greased more often.
Semi-Annually:
•
Drain the hydraulic system fluid. Flush out the
hydraulic system and fill with new, clean fluid.
However, if the fluid turns dark or becomes milky
colored, it should be changed as soon as possible.
Inspect hydraulic hoses and couplings every operat-
ing day. Repair or replace if leakage, cracking, wear
or damage is evident. Damaged hoses or couplings
can fail resulting in injury or property damage.
Note: Keep all decals clean and legible. Replace
decals when necessary with new decals listed
in the Parts List of this manual.
