WARNING: Explosive separation of tire and
rim parts is possible when they are serviced
incorrectly. Do not stand in front or over tire
assembly when inflating.
The recommended operating tire pressure is approxi-
mately 5-7 psi for all tires. Overinflating above
recommended tire pressure can reduce the life of the
tire. Check tire pressure before driving the vehicle.
NOTE: For high loads 8-10 psi is recommended for the
center and rear tires. The recommended tire pressure
while using the snow plow option is 8-12 psi in the front
tires.

WARNING: Do not rely on a lifting device
alone to support machine while servicing.
Always use jack stands or wooden blocks to
support vehicle while work is being performed
with machine raised.
NOTE: Drive chain is set taught at the factory, so it will
not reach normal stretch limits until vehicle has
experienced reasonable hours of operation (50 hrs).

tight, a1/2 link will need to be removed.
• If chain is still loose after the 1/2 link is already
removed, the chain should be replaced using a 98
