ASSEMBLY
REPLACING PACKING LUBRICANT
The ATV engine is shipped with packing lubricant in it. This
lubricant must be drained and replaced with new engine
lubricant before attempting to operate the ATV. Do not start
the engine while it still contains the packing lubricant.
Always use a 4-stroke motor lubricant that meets or exceeds
the requirements for API service classification SJ.

CHANGING/ADDING ENGINE LUBRICANT
To change engine lubricant:
Lubricant should be changed while the engine lubricant is still
warm, but not hot. This allows the lubricant to drain quickly
and completely.

Park vehicle on level ground.

Remove oil cap/dipstick.

Place a container underneath the oil drainage bolt to col-
lect used lubricant as it drains.

Unscrew the oil drainage bolt and remove the bolt, spring,
and oil strainer.

Allow lubricant to drain completely.

Remove oil filter cap and oil filter.

Using a non-flammable solvent, clean the oil strainer and
oil filter.

Inspect rubber o-ring on filter cap and replace if dam -
aged.
CAUTION:
Attempting to operate the ATV with a damaged or missing
o-ring will result in engine failure.

Reinstall oil filter, o-ring if removed, and filter cap.

Reinstall oil strainer, spring, and oil drainage bolt. Torque
oil drainage bolt to 18 ft.lbs. (24 Nm).

Fill crankcase with specified lubricant as described at the
beginning of this section.
NOTE: Used lubricant should be disposed of at an approved
disposal site. See your local oil retailer for more informa-
tion.
To check lubricant level:

Park vehicle on level ground.

Unscrew the oil cap/dipstick and remove.

Wipe dipstick clean and re-seat in hole, but do not re-
thread.

Remove the dipstick and inspect the lubricant level. Level
should be between the minimum and maximum marks on
the dipstick.

If lubricant is below minimum mark on dipstick, add lu-
bricant until level falls between minimum and maximum
marks on the dipstick.
CAUTION:
Attempting to start the engine before it has been properly
filled with lubricant will result in equipment failure.
