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.
Engine Maintenance
Note: Determine the left and right sides of the
machine from the normal operating position.
General Air Cleaner
Maintenance
• Check the air cleaner body for damage which
could possibly cause an air leak. Replace a
damaged air cleaner body. Check the whole
intake system for leaks, damage, or loose hose
clamps.
• Service the air cleaner filter when the air
cleaner indicator (Figure 43) shows red or
every 450 hours (more frequently in extremely
dusty or dirty conditions). Do not over service
the air filter.

• Be sure the cover is seated correctly and seals
with the air cleaner body.
Servicing the Air Cleaner
1. Pull the latch outward and rotate the air cleaner
cover counter-clockwise (Figure 44).

2. Remove the cover from the air cleaner body
(Figure 44).
3. Before removing the filter, use low pressure
air (40 psi, clean and dry) to help remove
large accumulations of debris packed between
outside of primary filter and the canister.
This cleaning process prevents debris from
migrating into the intake when the primary
filter is removed.
