Performing scheduled maintenance will promote safe, reliable operation of your attachment. In-
spect and grease components every eight hours of operation, as indicated on the following check-
list. Use maintenance procedures described in this manual. If you are not able to safely and com-
petently perform these procedures, have a Genesis dealer perform them.
After the first
80 hours
of operation, check all bolts, including slewing ring bolts.
Change gearbox lube after first
50 hours
of operation.
MAINTENANCE SCHEDULE
Operating the attachment with excessively worn blades or main bearings could lead to premature
cylinder failure. Excessive deflection of the upper jaw from these conditions will transfer side load
-
ing forces to the cylinder piston and barrel, which causes undue pressure on the wear bands of
the piston, potentially resulting in cylinder failure.
Pounding the upper jaw lever arm or cylinder clevis on the ground or a hard object to clear a
material jam can cause high pressure hydraulic spikes to the attachment and excavator which can
damage the hydraulic system components. These spikes can damage the cylinder piston seals,
which will allow oil to bypass and wash out the piston wear bands, resulting in premature and pos-
sibly catastrophic system failures.
Scheduled Maintenance
3
Replace slewing ring bolts every 2000 hours.
3
Reseal cylinder annually or between 2000 and 3000 hours.*
3
Reseal swivel every 2 years or at the time of cylinder resealing.
* Note:
If used more than (1) 8 hour shift per day, reseal at 2000 hours. If the cylinder has
been previously resealed, reseal at 1000 - 1500 hours.
Extreme operating conditions may require shortened
maintenance intervals.
