Replacing the Fuel Filter
Service Interval: Every 800 hours (Sooner if the fuel flow
is restricted)
An in-line filter is incorporated into the fuel line between the
fuel tank and carburetor
(Figure
DANGER
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or explosion
from gasoline can burn you and others and can
damage property.
• Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open area.
Wipe up any gasoline that spills.
• Never smoke when draining gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
1. Close the fuel-shutoff valve, loosen the hose clamp on
the carburetor side of filter, and remove the fuel line
from the filter

Electrical System
Maintenance
Servicing the Battery
Properly maintain the battery electrolyte and keep the top of
the battery clean. Store the machine in a cool place to prevent
the battery from running down.
Check the electrolyte level every 50 operating hours or, if
machine is in storage, every 30 days.
DANGER
Battery electrolyte contains sulfuric acid which is a
deadly poison and causes severe burns.
• Do not drink electrolyte and avoid contact with
skin, eyes, or clothing. Wear safety glasses to
shield your eyes and rubber gloves to protect
your hands.
• Fill the battery where clean water is available for
flushing the skin.
Maintain the cell level with distilled or demineralized water.
Do not fill the cells above the bottom of the split ring inside
each cell.
Keep the top of the battery clean by washing it periodically
with a brush dipped in ammonia or bicarbonate of soda
solution. Flush the top surface with water after cleaning it.
Do not remove the fill caps while cleaning the battery.
Ensure that the battery cables are tight on the terminals to
provide good electrical contact.
WARNING
Incorrect battery cable routing could damage the
machine and cables causing sparks. Sparks can
cause the battery gasses to explode, resulting in
personal injury.
• Always disconnect the negative (black) battery
cable before disconnecting the positive (red)
cable.
• Always connect the positive (red) battery cable
before connecting the negative (black) cable.
If corrosion occurs at the terminals, disconnect the cables,
negative (-) cable first, and scrape the clamps and terminals
separately. Reconnect the cables, positive (+) cable first, and
coat the terminals with petroleum jelly.
