Lubrication
Greasing the Bearings and
Bushings
T he mac hine has g rease fittings that m ust be
lubricated regularly with No . 2 General Pur pose
Lithium Base Grease . If the mac hine is operated
under nor mal conditions , lubricate all bearings
and bushings after ev er y 50 hours of operation or
immediately after ev er y w ashing .
Bearings rarely fail from defects in materials or
w orkmanship . T he most common reason for
failure is moisture and contamination w orking
its w a y past the protecti v e seals . Bearings that
are g reased will rely upon regular maintenance to
purg e har mful debris from the bearing area. Sealed
bearings , suc h as the castor wheel bearings , rely on
an initial fill of special g rease and a robust integ ral
seal to k ee p contaminants and moisture out of the
rolling elements .
T he sealed bearings require no lubrication or shor t
ter m maintenance . T his minimizes routine ser vice
required and reduces the potential of turf damag e
due to g rease contamination. T hese sealed bearing
pac kag es will pro vide g ood perfor mance and life
under nor mal use , but periodic inspections of
bearing condition and seal integ rity should be
conducted to a v oid do wntime . T hese bearings
should be inspected seasonally and re placed
