General Maintenance
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline,
petroleum-based products, penetrating lubricants,
etc., come in contact with plastic parts. Chemi-
cals can damage, weaken or destroy plastic which
could result in serious personal injury.

Checking the Fuel Cap, Tank, and Lines
WARNING:
Check for fuel leaks. A leaking fuel cap, tank,

immediately. If you find any leaks, correct the
