Tire inflation
DANGER
Explosion hazard!
Welding to a wheel can create an explosive air
and gas mixture. Removing air from the tire or
loosening the tire on the wheel (breaking the
bead) will NOT eliminate the hazard. ALWAYS
remove the tire completely from the wheel be-
fore welding.
Failure to comply will result in death or serious
injury.
WARNING
Explosion hazard!
When inflating tires, use a clip-on air chuck
with a gauge, remote valve, and hose long
enough to allow you to stand to one side and
NOT in front of or over the wheel assembly.
Keep others out of the DANGER AREA. Never
inflate a tire beyond the maximum allowable
pressure printed on the tire.
Failure to comply could result in death or se-
rious injury.
WARNING
Explosion hazard!
Do not remove, install, or make repairs to a tire
on a wheel rim. Take the tire and rim to a tire
shop where persons with special training and
special safety tools are available.
Failure to comply could result in death or se-
rious injury.
Upon receiving your tractor, check the air pressure in the
tires and recheck every 50 hours or weekly. Refer below
table for tire pressure for normal operation.
Operation Front
Field 220 kPa (32 psi)
Haulage
220 kPa (32 psi)
Industrial
310.3 kPa (45.0 psi) 165.0 kPa (23.9 psi)
See the tables for tire pressure and permissible load for
more details.
When checking tire pressures, inspect the tires for dam-
aged tread and side walls. Incorrect pressure will lead to
premature tire failure.
Do not exceed the load for the pressures listed. Do not
over-inflate or under-inflate the tire.
