Grease / Oil Build-Up - Remove

ACCUMULATED GREASE AND OIL ON A MACHINE
IS A FIRE HAZARD. REMOVE SUCH DEBRIS WITH
STEAM CLEAN ING OR HIGH PRESSURE WATER.
SEE THE NOTE BELOW FOR DETAILS.
NOTICE
Shoot grease in slowly, and carefully prevent
damage to the bearing seals. Use extra caution
when using a high pressure or high volume
grease gun.
Wipe all fittings, caps, and plugs before servicing.
Keep a close watch for leaks. If leaking is observed, find the
source, and correct the leak.
Check the fluid levels more frequently than the recom mend-
ed periods if leaking is suspected or ob served, until the
problem is corrected.

Jackshaft Bearings - Lubricate the Fittings

Lubricate the two fittings (2) (one on each jackshaft bearing)
3-4 pumps. Note: cover can be removed to ensure bearings
are adequately greased.
Wheel Hub Bearings - Inspect & Grease
The wheel bearings on the ma chine are sealed and generally
do not require service. They are, however, greasable. Locate
the zerk on the inside of the wheel assembly. Apply 3-4
pumps of grease.
If abnormal wear or other damage seems present, replace
bearings immediately. Worn or frozen bearings can damage
the drive components
