CleaningtheEngineAndDeck
Any fuel or oil spilled on the machine should be wiped
off promptly. Do NOT allow debris to accumulate
around the cooling fins of the engine or on any other
part of the machine, especially the belts, pulleys and
other moving parts. Clean the underside of the deck
with a wisk broom, scraper or forced air after each
mowing.
IMPORTANT:The use of a pressure washer or garden
hose to clean your tractor is NOT recommended. It may
cause damage to electrical components, spindles,
pulleys, bearings or the engine. The use of water will
result in a shortened life of the tractor and reduce its
serviceability.
Lubrication
WARNING: Before lubricating, repairing, or
inspecting, always disengage PTO, move
speed control lever into neutral position, set
parking brake, stop engine and remove key to
prevent unintended starting.

Briggs & Stratton Operator/Owner Manual (or
Tecumseh engine's Owner's Manual) packed with your
unit.

purpose grease after every 25 hours of operation or
once a season. See Figure 23.

heater, furnace, clothes dryer or other gas
appliances
The battery is sealed and is maintenance-free. Acid
levels cannot be checked.
Always keep the battery cables and terminals clean
and free of corrosive build-up.
After cleaning the battery and terminals, apply a
light coat of petroleum jelly or grease to both
terminals
Always keep the rubber boot positioned over the
positive terminal to prevent shorting.
IMPORTANT:If removing the battery for any reason,
disconnect the NEGATIVE (Black) wire from it's
terminal first, followed by the POSITIVE (Red) wire.
When re-installing the battery, always connect the
POSITIVE (Red) wire its terminal first, followed by the
NEGATIVE (Black) wire. Be certain that the wires are
connected to the correct terminals; reversing them
could damage to your engine's alternating system.
