WARNING
Except when checking or changing components, always keep
protective shields on for safety as well as for cleanliness.

WARNING
Keep engine clean of oil, grease, trash and debris which can
cause engine overheating, fires and belt wear. Clean only after
engine has completely cooled. Wear gloves to protect hands
from cuts, puncture wounds and burns.

WARNING
DO NOT have engine running when servicing or making
adjustments to the vehicle. Shut engine off, place transmission
in park and remove ignition switch key for maximum safety.

DANGER
Repairs or maintenance specifically requiring engine power
should be performed by trained personnel only. Transmission
gear should be set in neutral with tires properly chocked or with
drive tires properly supported off the floor. Enclosed areas
should be properly ventilated to prevent carbon monoxide
poisoning.

DANGER
Exercise extreme caution when working with and around the
belt drive. Make certain the engine cannot be accidentally
started. Shut engine off and remove ignition switch key for
maximum safety. Repairs or maintenance requiring engine

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.
Remain alert for unusual noises; they could be signaling
a problem. Visually inspect vehicle 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.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled
personnel. Consult your Land Pride dealer when
assistance is needed.
