Engine Oil Change
Always change the oil at the intervals outlined in the Periodic Maintenance Chart beginning
on page 97. Perform the initial break-in oil change after the first three hours of operation.
Always change both oil filters and clean the oil screens whenever changing oil.
NOTE: Change the oil more frequently on vehicles subjected to severe use.
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. Do not allow the vehicle to be without oil and filter overnight.
Always replace the oil and filters within a few hours of draining the oil.
