8Make sure the brakes operate smoothly
and that the free play is correct.
8Make sure the brakes do not drag.
8Make sure the brakes are not spongy. All
air must be bled from the brake system.
Replacement of brake components requires
professional knowledge. These procedures

EBU00805Lubricating the drive chain
The drive chain must be cleaned and lubricated
at the intervals specified in the periodic mainte-
nance and lubrication chart, otherwise it will
quickly wear out, especially when riding in dusty
or wet areas. Service the drive chain as follows.cCThe drive chain must be lubricated after
washing the ATV or riding in the rain.
1. Clean the drive chain with kerosene and a
small soft brush.
cCTo prevent damaging the O-rings, do not
clean the drive chain with steam cleaners,
high-pressure washers or inappropriate sol-
vents.
2. Wipe the drive chain dry.

EBU00413Troubleshooting
Although Yamaha machines receive a rigid
inspection before shipment from the factory,
trouble may occur during operation.
Any problem in the fuel, compression, or ignition
systems can cause poor starting and loss of
power. The troubleshooting chart describes a
quick, easy procedure for making checks. If your
machine requires any repair, take it to a Yama-
ha dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to
properly service your machine. Use only gen-
uine Yamaha parts on your machine. Imitation
parts may look like Yamaha parts, but they are
often inferior. Consequently, they have a shorter
service life and can lead to expensive repair
bills.

cCBe sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor
oils (often labeled “Energy Conserving”)
contain anti-friction additives which will
cause clutch and/or starter clutch slippage,
resulting in reduced component life and poor
engine performance.

fFVeiller à ce que l’huile de moteur utilisée ne
contienne pas d’additifs antifriction. Les huiles
pour voitures (portant souvant la désignation
“ENERGY CONSERVING”) contiennent des
additifs antifriction qui vont faire patiner
l’embrayage et/ou l’embrayage de démarreur,
ce qui va provoquer une réduction de la dura-
bilité des organes et une baisse de rendement.
