Maintenance

Checking the Tire Pressure

Service Interval: Before each use or daily
Check the tire pressure every 8 hours or daily to ensure
proper levels. Fill the tires to 124 kPa (18 psi). Also, check
the tires for wear or damage.

Inspecting the Wheels/Tires

Service Interval: 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.
Torque the front lug nuts to 75 to 102 N-m (55 to 75 ft-lb)
and the rear lug nuts to 95 to 122 N-m (75 to 90 ft-lb).
Operating accidents, such as hitting curbs, can damage a
tire or rim and also disrupt wheel alignment, so inspect tire
condition after an accident.
