Checking the Rear Wheel
Alignment
Service Interval: Every 500 hours
To prevent excessive tire wear and ensure safe machine
operation, align the rear wheels to 3 to 8 mm (0.12 to 0.31
inch).
1. Set the rear wheels in the straight ahead position.
2. Measure and compare the distance between the front
sidewalls and the rear sidewalls at the wheel center
height. The distance between the front sidewalls must
be set 3 to 8 mm (0.12 to 0.31 inches) less than the
distance between the rear sidewalls.

Cooling System Safety

•
Swallowing engine coolant can cause poisoning;
keep out of reach from children and pets.
•
Discharge of hot, pressurized coolant or touching a hot
radiator and surrounding parts can cause severe burns.
– Always allow the engine to cool at least 15 minutes
before removing the radiator cap.
– Use a rag when opening the radiator cap, and open
the cap slowly to allow steam to escape.

and, if necessary, clean any debris off these parts. However,
it will be necessary to check and clean it more frequently in
extremely dusty and dirty conditions.
1. Park the machine on a level surface, shut off the engine,
engage the parking brake, and remove the key from
the ignition switch.
2. Clean the radiator screen.
