Caster Wheels
7.14.2.1 Tire Inflation
a. Visually check daily that tires have not lost
pressure.
Under-inflation of drive tires can
cause side wall cracks.
DANGER
To avoid severe personal injury or death
caused by machine runaway, shut off engine
and remove key before performing any of the
following checks and/or adjustments.
b. Measure tire pressure annually with a gauge.
Maintain the pressure at 10 psi (69 kPa).
If caster wheels shimmy a possible cause
is over-inflation:
DANGER
•
Never install a tube in a cracked wheel rim.
•
Never weld a wheel rim.
•
Make sure all the air is removed from a tire
before removing the tire from the rim.
•
Never use force on an inflated or partially
inflated tire. Make sure the tire is correctly
seated before inflating to operating pressure.
•
Do not remove, install or make repairs to a
tire on a rim unless you have the proper
equipment and experience to perform the
job. Take the tire and rim to a qualified tire
repair shop.
•
If the tire is not in correct position on the rim,
or if too full of air, the tire bead can loosen
on one side, causing air to leak at high speed
and with great force. An air leak of this
nature can thrust the tire in any direction,
endangering anyone in the area.
