To prevent injury caused by a
broken socket, use only sockets
designed for impact wrench use.
Never use a conventional socket.
Tire condition should be inspected per the Periodic Ser-
vice Schedule (See SERVICE SCHEDULE on page 4).
Inflation pressures should be checked when the tires are
cool. When removing wheels with an impact wrench, use
only impact sockets. Regular sockets are not designed
for impact pressures exerted by power tools.
A tire explosion can cause severe
injury or death. Never exceed the
inflation pressure rating on the tire
sidewall.
To prevent tire explosion, pressurize the tire
with small amount of air applied
intermittently to seat beads. Never exceed
the tire manufacturer’s recommendation
when seating a bead. Face and eyes should
be protected from escaping air when
removing valve core.
Use caution when inflating tires. Due to the
low volume of these small tires, over-
inflation can occur in a matter of seconds.
Over-inflation could cause the tire to
separate from the wheel or cause the tire to
explode, either of which could cause
personal injury.
Do not use low inflation pressure tires on any
vehicle. Do not use any tire which has a
recommended inflation pressure less than the
inflation pressure recommended in Owner’s Manual
Use caution when inflating tires. Due to the low volume of
these small tires, over-inflation can occur in a matter of
seconds. Over-inflation could cause the tire to separate
from the rim or cause the tire to explode, either of which
could cause personal injury.
Tire inflation should be determined by the condition of the
terrain. See
GENERAL SPECIFICATIONS
section for
recommended tire inflation pressure (See GENERAL
SPECIFICATIONS on page 155). For outdoor applica-
tions with major use on grassy areas, the following
should be considered. On hard turf, it is desirable to have
a
slightly
higher inflation pressure. On very soft turf, a
lower pressure prevents tires from cutting into the turf.
For vehicles being used on paved or hard surfaces, tire
inflation pressure should be in the higher allowable
range, but under no condition should inflation pressure
be higher than recommended on tire sidewall.
All four
tires
should have the same pressure for optimum han-
dling characteristics. Be careful not to over inflate. Due to
the low volume of these small tires, over inflation can
occur in a matter of seconds. Be sure to install the valve
dust cap after checking or inflating.
Tire Repair
The vehicle is fitted with low pressure tubeless tires
mounted on one piece rims.
Generally, the most cost effective way to repair a flat tire
resulting from a puncture in the tread portion of the tire is
to use a commercial tire plug.
NOTICE: Tire plug tools and plugs are available at
most automotive parts outlets and have the advan-
tage of not requiring the tire be removed from the
wheel.
If the tire is flat, remove the wheel and inflate the tire to
the maximum recommended pressure for the tire.
Immerse the tire in water to locate the leak and mark with
chalk. Insert tire plug in accordance with manufacturer’s
specifications.
If the tire is to be removed or mounted, the tire changing
machine manufacturer’s recommendations must be fol-
lowed in order to minimize the possibility of personal
injury.
To prevent injury, be
sure mounting/
demounting machine
is anchored to floor. Always wear
OSHA approved safety equipment
when mounting/demounting tires.
Wheel Installation
Do not tighten lug nuts to more
than 85 ft. lbs. (115 Nm) torque.
NOTICE: It is important to follow the ‘cross
sequence’ pattern when installing lug nuts. This will
assure even seating of the wheel against the hub.
With the valve stem to the outside, mount the wheel onto
the hub with lug nuts. Finger tighten lug nuts as shown.
Then, tighten lug nuts to the torque values below in 20 ft.
lbs. (30 Nm) increments following the same pattern.
