BATTERY - FIG. 12
Check and maintain level of electrolyte every 20
hours of operation, or once each month. Fill slightly
above plates with distilled water. Don't overfill.
Keep battery posts and cable ends clean and lightly
coated with petroleum jelly. Maintain boot on
positive post.
AIR CLEANER — FIG. 20
IMPORTANT: If air cleaner becomes too dirty,
engine will not receive sufficient air to run
properly. Symptoms: Loss of power, flooding,
hard to start and overheating.
The air cleaner has a paper element. It must be
kept clean for proper engine operation and long life.
Clean paper element at least every 50 hours by tapping
it lightly on a flat surface. Replace after every 100
to 200 hours of operation. Clean or replace more
frequently under severe conditions. Hold a light bulb
inside ring to check element. Never wash or oil
paper element. If it becomes plugged and cannot be
cleaned by tapping, it should be replaced.
IMPORTANT: Never run engine with air clean¬
er removed. Dirt will enter engine and score
cylinder.
TIRES AND WHEELS
Keep treads free of debris and tires inflated to
correct pressures. Tires which are overinflated or
underinflated will wear more rapidly. Proper pres¬
sures for various tire sizes are as follows:

Rear View — Seat Raised
1. Transmission Cooling Fan
FRONT
16 x 6.50-8 .8-10 psi
REAR
23x 10.50-12 .6-8 psi
Periodically check front wheel bolts for 30 ft.-
Ibs. torque. Rear wheel hub bolts (10) should be
tightened to 50-60 ft.-lbs. torque. Rear wheel lug
bolts (2) should be tightened to 40 ft.-lbs. torque.
FUEL FILTER - FIG. 20
Fuel filter is an in-line filter. If excessively dirty,
as viewed through transparent case, shut off fuel
valve, remove and replace filter.
Inspect fuel tank at start of each operating season.
If water or dirt is present, clean tank and fuel line.
COOLING SYSTEM
Inspect engine cooling fins frequently and re¬
move any accumulation of debris.
Inspect rotary screen at rear of engine daily for
debris plugging screen. To clean, wipe chaff off rotary
screen on engine.
NOTE: If air pressure is available, blowing air
in reverse direction into fins will dislodge
grass or dirt accumulations.
IMPORTANT: A dirty screen or fins can cause
overheating and damage to engine. Clean them
frequently.
Frequently check transmission fan, Fig. 21, to
see if it is running free and is clean.
A
CAUTION: To prevent a fire hazard,
keep engine fins and surrounding
area free of grass, leaves and ex¬
cessive grease.
