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.

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 check the oil
level.
5. The oil level should be between the mini-
mum and maximum level marks. If the
level is low, add oil to raise it to the proper
level.

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.
Recommended oil:
See page 10-2.

between the maximum and minimum
marks.

To change the coolant
w
Wait for the engine and radiator to cool
