Air Filter Maintenance Guideline
Air filter maintenance should be adjusted according to riding conditions.
Air filter maintenance must be increased in frequency when riding on snow, dry
sand, dirt, gravel or similar conditions which have a high dust or particle
dispersion.
Riding in a group in these conditions will require increasing the air filter
maintenance frequency further.
NOTE:
Accessory filters and pre-filter are available for such conditions. Contact an
authorized dealer for details.
Severe Duty Use
If your vehicle is used in the following conditions, refer to the Severe Duty section
of the maintenance schedule.
– Repeated hauling of loads at more than 75% the maximum capacity.
– The increase workload applied to the drive system accelerates the differentials,
gearbox/transmission, and engine oil life. This reduces internal component
longevity if not replaced more frequently.
– Driving at excessive speeds for prolonged amount of time.
Higher than the average utility or commercial use requires more frequent fluid
and wear component replacement than trail, recreational, or occasional utility
purposes.
Extreme Cold Condition
An engine that is frequently operated at or below an ambient temperature of -25 °
C (-13 °F) will require an increase in service and maintenance schedule.
Any combustion engine operated at these low ambient temperature will collect
an increased amount of condensation at every startup/warm-up.
Since the engine is not reaching operating temperatures for extended periods of
time, the oil is starting to be strongly diluted with water and gas residue (more
water content).
An engine needs to reach operating temperature, in order to be able to evaporate
