Troubleshooting
Using Troubleshooting Chart
If you are experiencing a problem that is not listed in this chart, see your
authorized dealer for service.
When you have checked all the possible causes listed and you are still
experiencing the problem, see your authorized dealer.
CAUTION: Avoid injury! Explosive separation of tire and rim
parts is possible when they are serviced incorrectly:
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.
Do not weld or heat a wheel and tire assembly. Heat can
cause an increase in air pressure resulting in an
explosion. Welding can structurally weaken or deform the
wheel.
Do not stand in front or over the tire assembly when
inflating. Use a clip-on chuck and extension hose long
enough to allow you to stand to one side.
Tire Size Pressure
Front: 11 x 4 - 5 138–173 kPa (20-25 psi)
Rear: 18 x 8.5 - 8 69–97 kPa (10–14 psi)
IMPORTANT: Avoid Damage! Improper care of machine plastic
surfaces can damage that surface:
Do not wipe plastic surfaces when they are dry. Dry wiping will
result in minor surface scratches.
Use a soft, clean cloth (bath towel, diaper, automotive mitt).
Do not use abrasive materials, such as polishing compounds, on
plastic surfaces.
Do not spray insect repellent near machine.
IMPORTANT: Avoid damage! Do not use rubbing compound on
painted surfaces.
