EBU19540Fuel Make sure that there is sufficient fuel in the tank.
(See page 4-15.)
WARNING
EWB00520
Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is overfilled,
fuel could spill out due to heat from the en-
gine or the sun.
Be careful not to spill fuel, especially on the
engine or exhaust pipe which can cause a
fire and severe injury. Wipe up any spilled
fuel immediately.
Do not refuel right after the engine has been
running and is still very hot.
Be sure the fuel tank cap is closed securely.EBU19560Engine oil Make sure that the engine oil is at the specified lev-
el. Add oil as necessary. (See page 8-17.)EBU19590Final gear oil Make sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 8-21.)
EBU19600Differential gear oil Make sure that the differential gear oil is at the
specified level. Add oil as necessary. (See page
8-22.)EBU19630Coolant Make sure that the coolant is at the specified level.
Add coolant as necessary. (See page 8-24.)NOTE:The coolant level must be checked on a cold en-
gine since the level varies with engine tempera-ture.
WARNING
EWB00510Wait for the engine and radiator to cool before
removing the radiator cap. You could be
burned by hot fluid and steam blown out under
pressure. Always put a thick rag over the cap
when opening. Allow any remaining pressureto escape before completely removing the cap.

NOTE:If a torque wrench is not available when installing
a spark plug, a good estimate of the correct torque
is 1/4–1/2 turn past finger tight. However, the spark
plug should be tightened to the specified torque assoon as possible.
4. Install the spark plug cap.
5. Install the panel.EBU23321Engine oil and oil filter cartridge The engine oil level should be checked before
each ride. In addition, the oil must be changed and
the oil filter cartridge replaced at the intervals spec-
ified in the periodic maintenance and lubrication
chart.
To check the engine oil level
1. Remove panel F. (See page 8-8.)
2. Place the ATV on a level surface.
3. Start the engine, warm it up for several min-
utes, and then turn it off.
4. Wait a few minutes until the oil settles before
checking.
5. Remove the engine oil filler cap, and then
wipe the dipstick off with a clean rag.6. Insert the dipstick into the filler hole (without
screwing it in), and then remove it again to
check the oil level.

NOTE:The engine oil should be between the minimumand maximum level marks.
7. 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.
8. Insert the dipstick into the oil filler hole, and
then tighten the engine oil filler cap.
9. Install the panel.To change the engine oil (with or without oil fil-
ter cartridge replacement)
1. Remove panel F. (See page 8-8.)
