Tire And Wheel Maintenance (continued)
WARNING! The types of wheels and tires usually
found on this equipment require special care when
servicing to prevent death or serious injury.
Do not infl ate the tires above the recommended
pressure. Be sure to replace tire ballast if equipped. See
manufacturer’s specifi cations for ballast requirements.
Keep wheel lug nuts tightened to manufacturer’s
recommendations.
A rise in tire pressure during operation is normal, and
should NOT be reduced.
Never reinfl ate a tire that has been run fl at or seriously
underinfl ated without removing the tire from the wheel.
Have the tire and wheel closely inspected for damage
before remounting.
When adding air to a tire, do so from a distance. Use
a long hose with self-attaching chuck. Always stand
behind tread when adjusting tire pressure.
Do not infl ate tires with fl ammable gases or from
systems using an alcohol injector.
Never cut or weld on a wheel with an infl ated
tire mounted on it. This could cause explosive
decompression.
Check that the tire size and wheel are correctly matched.
When replacing the tires, ensure the tires are of the
appropriate rating specifi ed by the manufacturer.
Tires should not be operated at speeds higher than their
rated speed. Most agricultural tires are rated for 20mph
maximum speed.
