Checking the Sealed
Bearings
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 rely upon
regular maintenance to purge harmful debris from the
bearing area. Sealed 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 if they are
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 the warranty.
Note:
Bearing life can be negatively affected by
improper wash-down procedures. Do not wash down
the machine when it is still hot and avoid directing
high-pressure or high-volume spray at the bearings.

Engine Maintenance

Engine Safety

•
Shut off the engine before checking the oil or
adding oil to the crankcase.
•
Do not change the governor speed or overspeed
the engine.

Servicing the Air Cleaner

Service Interval: Every 200 hours (more frequently in
extreme dusty or dirty conditions).
•
Check the air cleaner body for damage which
could cause an air leak. Replace it if it is damaged.
Check the whole intake system for leaks, damage,
or loose hose clamps.
•
Service the air cleaner at the recommended
service interval or earlier if engine performance
suffers due to extremely dusty, dirty conditions.
Changing the air filter before it is necessary only
increases the chance of dirt entering the engine
when the filter is removed.
•
Ensure that the cover is seated correctly and seals
with the air-cleaner body.
1. Release the latches that secure the air-cleaner
cover to the air-cleaner body

2. Remove the cover from the air-cleaner body.
3. Before removing the filter, use low-pressure
air—276 kPa (40 psi), clean and dry—to help
remove large accumulations of debris packed
between the outside of primary filter and the
canister. Avoid using high-pressure air which
could force dirt through the filter into the intake
tract. This cleaning process prevents debris
from migrating into the intake when you remove
the primary filter.
