Inspect Tires: Check for fissures or any
other damage. Use a tire gauge to check
the tire pressure. Adjust the tire pressure
per the image above.
Always turn off engine and allow the machine to cool down completely before accessing the engine, muffler, radiator or other hot components
Coolant: Check the coolant level of the reservoir
tank (B). It should be between the upper and lower
limits marked on it when the engine is warm. If the
engine is cold, the coolant level must be at the low
line on the reserve tank. When necessary, add a
pre-diluted coolant with an antifreeze to water ratio
that suits the local climate*.

Release the three latch hooks on the air cleaner
canister cover and remove the cover. Never wash
the filter or attempt to clean the filter by tapping
the filter against another object. Apply
compressed air from inside of the element to
blow away the dust. Clean every 100 hours or if
necessary, replace every 1 year or if necessary.

Alternator / Fan Belt
Using the thumb, gently apply pressure to the
midpoint (A) of the alternator/fan belt between
the pulleys. Check whether the alternator/fan
belt deflects inward by approximately 0.4 to 0.6
in. (10 to 15 mm). If the deflection is not as
specified, adjust the tension of the alternator/fan
belt. Adjust every 50 hours, replace if necessary.
