Changing Tires/Wheels
FOAM FILLED TIRES ARE EXTREMELY HEAVY. CARE MUST BE TAKEN TO AVOID
PERSONAL INJURY.
Always block the wheels before raising the machine.
When a tire change is necessary, follow these tips:
1. While the machine is on the ground, loosen but
do not remove
lug nuts.
NOTE: Wheels may spin when attempting to loosen lug nuts without the weight
of the machine on the wheels. Loosen lug nuts enough to break free,
but leave them tight for safety.
2. Raise and support the machine (see
Raising the Machine
).
3. Remove lug nuts and pull the wheel off.
4. Install the replacement wheel and tighten the lug nuts.
5. Lower the machine to the ground.
6. Torque lug nuts to 75 to 85 ft.-lbs. (102 to 115 Nm).
