SERVICE & MAINTENANCE
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE,
DISENGAGE THE HYDRAULICS, AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
WARNING
5.6 LUBRICATION
Figure 5.6, One zerk is on the discharge chute base.
Lubricate the machine periodically with a lithium-based
grease. Extreme working conditions will require more
frequent greasing.
Grease the following points every 50-100 hours of
operating time:
Do not over grease bearings. Overfilling can lead to
excessive heat and/or unseating of the seals. Add
grease slowly and under light pressure. Whenever
possible, rotate bearing slowly while lubricating.
NOTE
Polyurea and lithium-based greases are not compatible.
Mixing the two grease types may lead to premature failure.
IMPORTANT
5.7 CHANGING HYDRAULIC OIL FILTER
Figure 5.7, Turn filter as directed to remove
Change the hydraulic oil filter after the first 50 hours of
operation and every 200 hours thereafter.
To change the hydraulic oil filter:
1. Using an oil filter wrench, turn the filter
counterclockwise.
2. Once the filter becomes loose, turn it out the rest of the
way with your hand.
3. Properly discard old filter.
4. Lube the rubber seal on the new filter (PN 16922) with
clean hydraulic oil.
5. Install the filter onto the threaded pipe. Turn with your
hand until the filter is finger tight.
6. Using an oil filter wrench, tighten the filter another ½
turn.
7. Check hydraulic oil level and fill if necessary.
