MAINTENANCE / SERVICE
Form # 131126 Issue 11/07 36
Wheel Bolts
Check and tighten wheel bolts after the first 10
hours of operation and every 100 hours thereafter.
Whenever a wheel is removed and re-installed,
check torque after one hour of operation.
Maintain torque of 80 to 90 ft.lbs. (110 to 120 N
⋅m)
Follow the proper bolt tightening sequence shown.
NOTE: When installing wheel, be sure valve stem
(C) points away from wheel support.
Tire Inflation
Check tire pressure daily. Maintain 100 psi (690 kPa)
on cutterbar tire and 70 psi (480kPa) on L/H and R/H
tires.
WARNING: Service tires safely. A tire
can explode during inflation and cause
serious injury or death. Never increase
air pressure beyond 35 psi (241 kPa) to
seat the bead on the rim. Replace the tire if it has
a defect. Replace a wheel rim, which has cracks,
wear or severe rust. Never weld a wheel rim. Make
sure all the air is removed from a tire before
removing the tire from a 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 is 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.
(A) - Use a safety cage if available.
(B) - Do not stand over tire. Use a clip-on chuck and
extension hose.
