Throttle lever
Once the engine is running, movement of the
throttle lever will increase the engine speed.
Regulate the speed of the machine by varying
the throttle position. Because the throttle is
spring-loaded, the machine will decelerate,
and the engine will return to an idle any time
the hand is removed from the throttle lever.
Before starting the engine, check the throttle to
be sure it is operating smoothly. Make sure it
returns to the idle position as soon as the lever
is released.
WARNING

Malfunction of the throttle could make it diffi-
cult to speed up or slow down when you need
to. This could cause an accident. Check the op-
eration of the throttle lever before you start
the engine. If the throttle does not work
smoothly, check for the cause. Correct the
problem before riding the ATV or consult a
Yamaha dealer.

PRE-OPERATION CHECKS
Before using this machine, check the following points:
ITEM ROUTINE PAGE
Brake
• Check operation, free play, fluid level and fluid leakage.
• Fill with DOT 4 (or DOT 3) brake fluid if necessary.5-5 ~ 5-7,
8-39 ~ 8-49
Clutch
• Check operation, condition and lever free play. 8-55
Parking brake
• Check operation, condition and cable slack. 8-51 ~ 8-53
Fuel
• Check fuel level.
• Fill with fuel if necessary.5-9 ~ 5-11
Engine oil
• Check oil level.
• Fill with oil if necessary.5-13 ~ 5-15,
8-15 ~ 8-23
Drive chain
• Check chain slack and condition.
• Adjust if necessary.5-15, 8-57 ~ 8-61
Throttle
• Check for proper throttle cable operation. 5-17, 8-37
Wheels and tires
• Check tire pressure, wear and damage.5-19 ~ 5-25,
8-69 ~ 8-71
Fittings and Fasteners
• Check all fittings and fasteners. 5-17
Lights
• Check for proper operation. 5-17, 8-83 ~ 8-89

CAUTION:

Be sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor
oils (often labeled “Energy Conserving”) con-
tain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting
in reduced component life and poor engine
performance.
EBU00498
Chain
Check the general condition of the chain and
check the chain slack before every ride. Lubri-
cate and adjust the chain as necessary. (See
pages 8-57 ~ 8-61 for details.)Oil quantity:
Total amount:
3.2 L
Periodic oil change:
2.4 L
With oil filter replacement:
2.5 L

Throttle lever
Check to see that the throttle lever operates
correctly. It must open smoothly and spring
back to idle position when released. Repair as
necessary for proper operation.
EBU00152
Fittings and Fasteners
Always check the tightness of chassis fittings
and fasteners before a ride. Take the machine
to a Yamaha dealer or refer to the Service Man-
ual for correct tightening torque.
EBU00153
Lights
Check the headlight and taillight to make sure
they are in working condition. Repair as neces-
sary for proper operation.
EBU00155
Switches
Check the operation of the headlight switch,
engine stop switch and any other switches. Re-
pair as necessary for proper operation.

Starting a warm engine
To start a warm engine, refer to the “Starting a
cold engine” section. The starter (choke)
should not be used. The throttle should be
opened slightly.
EBU00538
Warming up
To get maximum engine life, always warm up
the engine before starting off. Never accelerate
hard with a cold engine! To see whether or not
the engine is warm, check if it responds to the
throttle normally with the starter (choke)
turned off.NOTE:

When the parking brake is used, engine speed
is limited to 2,300 r/min. Be sure the parking
brake is released before moving the throttle le-
ver. Otherwise, the engine will misfire, pre-
venting normal operation.

Engine oil
Engine oil level measurement
1. Place the ATV on a level surface.
2. Warm up the engine for several minutes,
and then stop it.
3. Remove the dipstick, and then wipe it off
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 be-
fore checking.
4. Remove the dipstick, and then check 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.
