OPERATION AND SERVICE INFORMATION
3-20
Read all of manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notes, Cautions and Warnings
turer’s recommendation when seating a bead. Protect face
and eyes from escaping air when removing valve core.
To reduce the possibility of severe injury caused by a bro-
ken socket when removing wheels, use only sockets
designed for impact wrench use.
Use caution when inflating tires. Overinflation could cause
the tire to separate from the wheel or cause the tire to
explode, either of which could cause severe injury.
Use caution when inflating tires. Due to the low volume of the small
tires, overinflation can occur in seconds. Overinflation could cause the
tire to separate from the wheel or cause the tire to explode.
Tire inflation will depend on the type of tires fitted but under no condition
should inflation pressure be higher than recommended on the tire side-
wall. Standard and optional tires should be inflated to pressure desig-
nated in GENERAL SPECIFICATIONS on page 4-1. If pressure is
not designated in GENERAL SPECIFICATIONS, inflate to pressure
designated on tire sidewall.
All four tires should have the same pres-
sure for optimum handling characteristics. Be sure to install the valve
dust cap after checking or inflating.
The vehicle is fitted with low pressure tubeless tires mounted on one
piece rims. When removing wheels with an impact wrench, use
only impact sockets. Regular sockets are not designed for
impact pressures exerted by power tools.
Generally, the most cost effective way to repair a puncture in the tread
is to use a commercial tire plug.
Tire plug tools and plugs are available at most auto-
motive parts outlets and have the advantage of not
requiring the tire be removed from the wheel.
If the tire is flat, raise vehicle and remove wheel. Refer to ‘Lifting the
Vehicle’ for proper lifting procedure and safety information. Inflate tire to
maximum recommended pressure. Immerse the tire in water to locate
the leak and mark with chalk. Insert tire plug in accordance with manu-
facturer’s specifications.
To reduce the possibility of severe
injury, be sure mounting/demount-
ing machine is anchored to floor.
Wear OSHA approved safety equipment when mounting/
demounting tires.
If the tire is to be removed or mounted, the tire changing machine man-
ufacturer’s recommendations must be followed in order to reduce pos-
sibility of severe injury. Be sure to position tire on wheel correctly. Arrow
on tire indicates rotation when moving forward.
Wheel Installation
T o r e d u c e t h e p o s s i b i l i t y o f
component damage, do not tighten
lug nuts to more than 85 ft. lbs. (115 Nm) torque.
It is important to follow the ‘cross sequence’ pattern
when installing lug nuts. This will assure even seat-
ing of the wheel against the hub.
With the valve stem to the outside, mount the wheel onto the hub with
lug nuts. Be sure to position the wheel on hub correctly with arrow indi-
cating direction of rotation when moving forward. Finger tighten lug nuts
in a ‘cross sequence’ pattern (Ref Fig. 17 on page 3-21). Tighten lug
nuts to 50 - 85 ft. lbs. (70 - 115 Nm) torque in 20 ft. lbs. (30 Nm) incre-
ments following the ‘cross sequence’ pattern.
