CHECKING/INFLATING
1. Using an air pressure gauge, measure the air pressure
in each tire. Adjust the air pressure as necessary to
meet the recommended inflation pressure.
2. Inspect the tires for damage, wear, or punctures.
NOTE: If repair is needed, follow the instructions
found on the tire repair kit or remove the wheel and
have it repaired professionally.
NOTE: Be sure all tires are the specified size and
have identical tread pattern.
3. Check the front wheel toe-in and toe-out and adjust
as necessary (see Steering/Frame/Controls - Measur-
ing/Adjusting Toe-Out).
4. Test drive the ATV on a dry, level surface and note
any pulling to the left or right during acceleration,
deceleration, and braking.
NOTE: If pulling is noted, measure the circumfer-
ence of the front and rear tires on the pulling side.
Compare the measurements with the tires on the
opposite side. If pulling is noted during braking only,
check and adjust the brakes as necessary and
recheck
operation
(see
Periodic
Maintenance
-
Hydraulic Brake Systems).
5. Increase the air pressure in the tires with the smallest
circumference measurement until all tires are equal
in circumference.
6. Repeat steps 4-5 as necessary to ensure proper han-
dling.
