MAINTENANCE AND LUBRICATION
Engine Oil
Oil and Filter Change
In order for the engine to function properly, maintain the engine oil at
the proper level, and change the oil and oil filter in accordance with the
Periodic Maintenance Schedule. Not only do dirt and metal particles
collect in the oil, but the oil itself loses its lubricative quality if used
too long.
The recommended oil change interval is 100 hours or every six
months, whichever comes first. Suggested break in oil change is at 25
hours or one month, whichever comes first. Severe use operation
requires more frequent service. Severe use includes continuous duty in
dusty or wet conditions, and cold weather operation. NOTE: Severe
use cold weather operation is all operating below 10° F, and operating
between 10° F and 30°F when most trips are slow speed and less than 5
miles. Be sure to change the oil filter whenever changing oil (Polaris
PN 3084963).
1. Place vehicle on a level surface.
2. Clean area around drain plug at the bottom of the oil tank.
3. Run engine for two to three minutes until warm. Shut engine off.
4. Place a drain pan beneath the oil tank and remove the drain plug.
5. Allow oil to drain completely.
6. Install a new sealing washer (PN 5850135) on oil drain plug.
NOTE: The sealing surfaces on the drain plug and the oil tank
should be clean and free of burrs, nicks or scratches.
7. Reinstall drain plug and torque to 14-17 ft. lbs. (1.93-2.35 kg/m)
CAUTION
Oil may be hot. Do not allow hot oil to come into contact with skin
as serious burns may result.
