Lubrication

Greasing the Bearings and
Bushings
The machine has grease fittings that must be
lubricated regularly with No. 2 General Purpose
Lithium Base Grease. If the machine is operated
under normal conditions, lubricate all bearings
and bushings after every 50 hours of operation or
immediately after every washing.
Bearings rarely fail from defects in materials or
workmanship. The most common reason for
failure is moisture and contamination working
its way past the protective seals. Bearings that
Figure 33
are greased will rely upon regular maintenance to
purge harmful debris from the bearing area. Sealed
bearings, such as the castor wheel bearings, rely on
an initial fill of special grease and a robust integral
seal to keep contaminants and moisture out of the
rolling elements.
The sealed bearings require no lubrication or short
term maintenance. This minimizes routine service
required and reduces the potential of turf damage
due to grease contamination. These sealed bearing
packages will provide good performance and life
under normal use, but periodic inspections of
bearing condition and seal integrity should be
conducted to avoid downtime. These bearings
should be inspected seasonally and replaced
