Service
Unless specifically required, DO NOT have engine run-
ning when servicing or making adjustments to tractor.
Park the machine on level ground. Place steering control
levers in the park brake position, disengage deck clutch,
lower deck, remove ignition switch key and disconnect
negative battery cable before doing any maintenance.
Wait for all movement to stop before adjusting, cleaning
or repairing. Repairs or maintenance requiring engine
power should be performed by trained maintenance per-
sonnel 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.
Before working on or under the deck, make certain
engine cannot be accidentally started. Shut engine off,
remove ignition switch key and disconnect negative bat-
tery cable for maximum safety. Repairs or maintenance
requiring engine power should be performed by trained
maintenance personnel only.
Except when changing or checking belt, always keep belt
covers on mower deck for safety as well as cleanliness.
Use a stick or similar instrument to clean under the
mower making sure that no part of the body, especially
arms and hands are under mower.
Keep your machine clean and remove any deposits of
trash and clippings, which can cause engine fires and
hydraulic overheating as well as excessive belt wear.
Clean up oil or fuel spillage. Allow machine to cool
before storing.
Clean flammable material from machine. Prevent
fires by keeping engine compartment, top of deck,
exhaust area, battery, hydraulic lines, fuel line, fuel
tank and operator's station clean of accumulated
trash, grass clippings, and other debris. Always clean
up spilled fuel and oil.
Always wear adequate eye protection when servicing the
hydraulic system and battery, or when grinding mower
blades and removing accumulated debris.
Use extra caution when handling gasoline and other
fuels. They are flammable and vapors are explosive.
Never attempt to start engine when there is a strong odor
of gasoline fumes present. Locate and correct cause.
Never remove the fuel cap or refuel tractor while engine
is running; never refuel near an open flame or near
devices which can create a spark. Refuel outdoors. Never
refuel or drain the fuel from the machine indoors.
Never run the engine in an enclosed area unless exhaust
is vented to the outside. Exhaust gases contain carbon
monoxide which is odorless and deadly poison.
Never attempt to make any adjustments or repairs to the
tractor drive system, mower deck or any attachment
