NOTE:_ Although the total number of clicks of a damping
force adjusting mechanism may not exactly match
the above specifications due to small differences
in production, the actual number of clicks always
represents the entire adjusting range. To obtain a
precise adjustment, it would be advisable to check
the number of clicks of each damping force adjust-
ing mechanism and to modify the specifications as
necessary. _
WARNING
_
Suspension components become hot dur-
ing operation. Never touch the compres-
sion damping force adjusting screw, the
rebound damping force adjusting screw or
the oil reservoir with your bare hand or
skin until suspension components have
cooled.
Always adjust the shock absorbers on the
left and right side to the same setting.

Recommended brake fluid: DOT4
Brake fluid replacement:
When disassembling the master cylinders or calipers, replace the brake fluid. Normally check the
brake fluid level and add fluid as required.
On the inner parts of the master cylinders and calipers, replace the oil seals every two years.
Replace the brake hoses every four years, or if cracked or damaged.

Engine oil and oil filter element
The engine oil level should be checked before
each ride. In addition, the oil must be changed and
the oil filter element replaced at the intervals spec-
ified in the periodic maintenance and lubrication
chart.
To check the engine oil level
1. Place the ATV on a level surface.
2. Start the engine, warm it up until the engine
oil has reached a normal temperature of
40°C, let it continue to idle for ten seconds or
more, and then turn the engine off.NOTE:_ To achieve the proper engine oil temperature for
an accurate oil level reading, the engine must
have first completely cooled down, and then
warmed up again for several minutes to normal
operating temperature. _

3. Remove the engine oil tank filler cap, wipe
the dipstick clean with a clean rag, insert it
back 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 minimum
and maximum level marks. _4. If the engine oil is below the minimum level
mark, add sufficient oil of the recommended
type through the engine oil tank filler hole to
raise it to the correct level.NOTE:_ When adding oil, be careful not to overfill the en-
gine oil tank; the oil level rises faster starting from
the half-level-portion on the dipstick. _5. Insert the dipstick into the engine oil tank filler
hole, and then tighten the engine oil tank filler
cap.
