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 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
Figure 36
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 if
damaged or worn. Bearings should operate smoothly
with no detrimental characteristics such as high heat,
noise, looseness or indications of corrosion (rust).
Due to the operating conditions these bearing/seal
packages are subject to (i.e. sand, turf chemicals, water,
impacts, etc.) they are considered normal wear items.
Bearings that fail due to causes other than defects in
materials or workmanship are typically not covered
under warranty.
Note: Bearing life can be negatively affected by
improper wash down procedures. Do not wash down the
unit when it is still hot and avoid directing high-pressure
or high volume spray at the bearings.
