85. If the engine oil is at or below the minimum
level mark, add sufficient oil of the recom-
mended type to raise it to the correct level.
NOTICE: Be sure the engine oil is at the
correct level, otherwise engine damage
may result.

6. Insert the dipstick into the oil filler hole, and then tighten the engine oil filler cap. To change the engine oil (with or without oil fil-
ter element cleaning)
1. Place the ATV on a level surface.
2. Start the engine, warm it up for several min- utes, and then turn it off.
3. Place an oil pan under the engine to collect the used oil.
4. Remove the engine oil filler cap, and then re- move the engine oil drain bolt to drain the oil
from the crankcase. NOTICE: When remov-
ing the engine oil drain bolt, the compres-
sion spring, oil strainer and O-ring will fall
out. Take care not to lose these parts.

WARNING
EWB02720Improper maintenance can result in loss of
braking ability. Observe these precautions:Insufficient brake fluid may allow air to enter
the brake system, reducing braking perfor-
mance.Clean the filler cap before removing. Use
only DOT 4 brake fluid from a sealed contain-
er.Use only the specified brake fluid; otherwise,
the rubber seals may deteriorate, causing
leakage.Refill with the same type of brake fluid. Add-
ing a brake fluid other than DOT 4 may result
in a harmful chemical reaction.Be careful that water does not enter the
brake fluid reservoir when refilling. Water
will significantly lower the boiling point of
the fluid and may result in vapor lock.
