Safe Servicing Practices

Refer to the Safety Precautions section of this manual for
more service safety information.

Service Introduction

Regular maintenance is the best prevention for costly
downtime or expensive, premature repair. The following
pages contain suggested maintenance information and
schedules which the operator should follow on a routine
basis. For more detailed information order the correct Parts
Manual and General Service Manual for your unit. Refer to
the Product Literature section of this manual for more infor-
mation.
Remain alert for unusual noises, which could signal a prob-
lem. Visually inspect the machine for any abnormal wear or
damage. A good time to detect potential problems is while
performing scheduled maintenance service. Correcting the
problem as quickly as possible is the best insurance.
Clear away heavy build-up of grease, oil and dirt, especially
in the engine and hydraulic component areas; minute dust
particles are abrasive to close-tolerance engine and hydrau-
lic assemblies.
Inspect mower daily for grass clippings and wire or string
tangles. The underside of the mower deck will collect a build-
up of grass clippings and dirt, especially when grass is wet or
has high moisture content. This build-up will harden, restrict-
ing blade and air movement which will probably result in a
poorer quality of cutting. Therefore it should be removed rou-
tinely. To do this it will be necessary to raise and block the
deck using jack stands or blocks in the full up position.
Scrape the build-up off from underneath.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled person-
nel. Consult your Hustler service center when assistance is
®
needed.

Torque Values

Particular attention must be given to tightening the
drive wheel lug nuts and blade spindle bolts. Failure
to correctly torque these items may result in the loss
of a wheel or blade, which can cause serious dam-
age or personal injury.
IMPORTANT: Any maintenance operation that requires
the removal of safety covers must be performed by a trained
service technician.

To lubricate these points:
1. Wipe away all old grease and dirt from the lubrication
fittings to prevent dirt or foreign material from enter-
ing as new grease is applied.
2. Use a high pressure grease gun to force in the new
grease. Apply pressure until clean grease oozes from
each lubrication point.
3. Wipe away any excess grease.
