CHANGING/ADDING ENGINE LUBRICANT
Engine lubricant has a major influence on engine perfor-
mance and service life. Engine lubricant level should be
checked before each use of the ATV.
For best engine performance, change the lubricant every 20
to 40 hours of operation. In dirty and dusty areas, the lubricant
should be changed more often.
Reference the chart below for the appropriate engine lubricant
to use based on the temperature range in your area.
NOTE: In very cold weather [below 5°F (15°C)], use
SAE10W-50 for good starting and smooth operation.

Always use a 4-stroke motor lubricant that meets or exceeds
the requirements for API service classification SJ. Check
lubricant level before each use.
NOTE: Non-detergent or 2-stroke engine lubricants will dam-
age the engine and should not be used.
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.
MAINTENANCE
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 and
washer.
 Allow lubricant to drain completely.
 Remove oil strainer cap and oil strainer.
SAE 10W-30
SAE 20W-40
SAE 10W-50
SAE 15W-40
 Using a non-flammable solvent, clean the oil strainer.
 Inspect rubber o-ring on strainer cap and replace if dam-
aged.
CAUTION:
Attempting to operate the ATV with a damaged or missing
o-ring will result in engine failure.
