cC
Do not shift gears without releasing the
throttle. Damage to the engine or drive train
may occur.
When slowing down or stopping, release the
throttle and apply the brakes smoothly and
evenly. As you slow down, shift to a lower gear.
Be sure that the engine has sufficiently slowed
before engaging a lower gear. Improper use of
the brakes or shifting can cause the tires to lose
traction, reducing control and increasing the
possibility of an accident.
w
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a
lower gear when the engine speed is too
high could cause the wheels to stop rotating.

RIDING DOWNHILL
When riding your ATV downhill, shift your weight
as far to the rear and uphill side of the ATV as
possible. Move back on the seat and sit with
your arms straight. Choose a low gear which will
allow the engine compression to do most of the
braking for you. Improper braking may cause a
loss of traction.
Use caution while descending a hill with loose or
slippery surfaces. Braking ability and traction
may be adversely affected by these surfaces.
Improper braking may also cause a loss of trac-
tion.
Whenever possible, ride your ATV straight
downhill. Avoid sharp angles which could allow
the ATV to tip or roll over. Carefully choose your
path and ride no faster than you will be able to
react to obstacles which may appear.

PERIODIC MAINTENANCE AND
ADJUSTMENT
Periodic inspection, adjustment and lubrication
will keep your machine in the safest and most
efficient condition possible. Safety is an obliga-
tion of the machine owner. The most important
points of machine inspection, adjustment and
lubrication are explained on the following pages.
w
Never service an engine while it is running.
Moving parts can catch clothing or parts of
the body, causing injury. Electrical compo-
nents can cause shocks or can start fires.
Turn off the engine when performing mainte-
nance unless otherwise specified. Have a
Yamaha dealer perform service if you are not
familiar with machine service.

Transmission oil measurement
1. Place the machine on a level surface.
2. Warm up the engine for several minutes,
and then stop it.
3. Remove the oil filler cap and wipe off the
dipstick with a clean rag. Insert the dipstick
in the filler hole without screwing it in.
NOTE:
Wait a few minutes until the oil level settles
before checking.
4. Remove the dipstick and inspect the oil
level.
5. The oil level should be between the maxi-
mum and minimum marks. If the level is
low, add oil to raise it to the proper level.
6. Install the oil filler cap.

8In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do not
use oils with a diesel specification of “CD”
or oils of a higher quality than specified. In
addition, do not use oils labeled “ENERGY
CONSERVING
II” or higher.
8Make sure that no foreign material enters
the crankcase.

Cooling system
1. Check the coolant level in the coolant
reservoir when the engine is cold as the

ature. The coolant level should be
between the maximum and minimum
marks.
