• Do not attempt to mount a tire without the proper
equipment and experience to perform the job.
• Do not inflate the tires above the recommended
pressure.

when inflating. Use a clip-on chuck and extension
hose long enough to allow you to stand to one side.

when the unit is warm from operation. Water can seep into
bearings and damage them.
Perform scheduled engine maintenance. Refer to engine
manual for detailed instructions.
