Inspecting the Wheels and
Tires
Service Interval: Before each use or daily—Check
the tire pressure.
After the first 8 hours—Torque the wheel-lug
nuts.
Every 100 hours—Torque the wheel-lug nuts.
Every 100 hours—Inspect the condition and
wear of the tires.
Check the tire pressure every 8 hours or daily to
ensure proper levels. Fill the tires to 138 kPa (20 psi).
Also, check the tires for wear or damage.
Check the wheels to ensure that they are mounted
securely after the first 8 operating hours and then
every 100 hours thereafter. Torque the front and rear
lug nuts to 102 to 108 N∙m (75 to 80 ft-lb).
Check the tire condition at least every 100 hours
of operation. Operating accidents, such as hitting
curbs, can damage a tire or rim and also disrupt
wheel alignment, so inspect the tire condition after
an accident.
