Engine Oil and Screen/Filter
Change the engine oil and clean the oil screen/fi lter at the scheduled
intervals. The engine should always be warm when the oil is
changed so the oil will drain easily and completely.
1. Park the ATV on level ground.
When the cap is removed, a compression spring, screen/fi lter, and
an O-ring will fall into the drain pan. Take care to account for these
components.
8. Turn the engine off. Check the oil level in the oil level inspection
window. The oil level should be between the low and high marks.
9. Inspect the area around the screen/fi lter cap for leaks.
2. Loosen the oil fi ll plug. Be
careful not to allow
contaminates to enter the
opening.
3. Remove the screen/fi lter cap
from the bottom of the crank-
case. Drain the oil into a drain
pan.
! CAUTION
4. Using a brush and parts
cleaning solvent, clean the
screen/fi lter; then clean the cap
and inspect the O-ring.
5. Install the O-ring, screen/fi lter,
compression spring, and the
O-ring; then secure with the
screen/fi lter cap. Tighten cap
to 1.5 kg-m (11 ft-lb).
6. Remove the oil fi ll plug; then
pour recommended oil into the
crankcase. Install fi ll plug.
7. Start the engine (while the ATV
is outside on level ground) and
allow it to idle for a few minutes.
