Maintenance

Replacing the Fuel Filter

Service Interval: Every 800 hours (Replace sooner if
the fuel flow is restricted.)
An in-line filter is incorporated into the fuel line between
the fuel tank and carburetor (Figure 47). Be sure the
arrow on the filter is pointing away from the fuel tank.
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 shut off valve, loosen the hose clamp
on the carburetor side of filter, and remove the fuel
line from the filter (Figure 47).

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 always
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.
The battery cables must be tight on the terminals to
provide good electrical contact.
WARNING
Incorrect battery cable routing could damage the
tractor 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.
