Introduction
WARNING:
Unless specifically required, DO
NOT have engine running when servicing or
making adjustments to unit. Place transmission
handle in the neutral position, disengage blade
engage lever, place thumb lock levers in the park
brake position, and remove ignition switch key.
Repairs or maintenance requiring engine power
should be performed by trained personnel only.
To prevent carbon monoxide poisoning, be sure
proper ventilation is available when engine must
be operated in an enclosed area. Read and
observe safety warnings in front of manual.
Your TrimStar was adjusted before it left the factory and
was checked during predelivery setup. However, after start-
up and continued use, a certain amount of break-in wear
will cause some adjustments to change.
Remain alert for unusual noises, they could be signaling
a problem. 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.
WARNING:
Keep your machine clean and
remove heavy deposits of trash and clippings,
they can cause engine fires as well as excessive
belt wear.
Clear away heavy build-up of grease, oil and dirt,
especially in the area of engine oil and engine combustion
air; minute dust particle are abrasive to close-tolerance
engine assemblies.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled
personnel. Consult your Hustler service center when
assistance is needed.
