Lubrication Recommendations
Oil and Filter Change - ATP 330 4x4
1. Obtain the correct oil filter and an adequate supply of oil so the oil
and filter change can be completed without interruption.
2. Position the vehicle on a level surface.
3. Clean the area around the drain plug on the bottom of the engine
crankcase.
4. Run the engine for two to three minutes until warm. Stop the
engine.
5. Place a drain pan beneath the engine crankcase and remove the
drain plug.
6. Allow the oil to drain completely.
7. Install a new sealing washer on the drain plug. NOTE: The
sealing surfaces on the drain plug and crankcase should be clean
and free of burrs, nicks or scratches.
CAUTION
If the ATV is left without oil in the system for extended periods, the
oil pump may lose its prime, which could result in engine damage.
Always replace the oil and filter within a few hours of draining the
oil. Do not allow the vehicle to be without oil overnight.
Contact with hot oil may result in serious burns. Do not allow hot
oil to come into contact with skin.
