PRE-OPERATION CHECKS
EBU19220
Pre-operation check list
Before operating this ATV, be sure to check the items listed in the following table.
NOTE:
The maintenance of some items in the table has to be performed by a Yamaha dealer. Refer to the “Periodic
maintenance and lubrication chart” on page 8-3 to determine which service should be performed by a
Yamaha dealer.
ITEM ROUTINE PAGE
Fuel
Check fuel level in fuel tank, and add recommended fuel if neces-
sary.
Check fuel line for leakage. Correct if necessary.4-8, 5-4
Transmission oil
Check oil level in transmission case, and add recommended oil to
specified level if necessary.
Check ATV for oil leakage. Correct if necessary.5-4, 8-9
Coolant
Check coolant level in reservoir, and add recommended coolant to
specified level if necessary.
Check cooling system for leakage. Correct if necessary.5-4, 8-11
Front brake
Check operation. If soft or spongy, have Yamaha dealer bleed
hydraulic system.
Check brake pads for wear, and replace if necessary.
Check brake fluid level in reservoir, and add recommended brake
fluid to specified level if necessary.
Check hydraulic system for leakage. Correct if necessary.5-4, 8-31, 8-32, 8-33

Coolant
The coolant level should be checked before each
ride. In addition, the coolant must be changed at
the intervals specified in the periodic maintenance
and lubrication chart.
EBU23501
To check the coolant level
1. Place the ATV on a level surface.
NOTE:
The coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture.
2. Check the coolant level in the coolant reser-
voir.
NOTE:
The coolant should be between the minimum and
maximum level marks.3. If the coolant is at or below the minimum level
mark, remove the seat. (See page 4-11.)
4. Open the coolant reservoir cover.

5. Remove the reservoir cap, add coolant or dis-
tilled water to the maximum level mark, and
then install the reservoir cap.
CAUTION:
ECB00401
If coolant is not available, use distilled water
or soft tap water instead. Do not use hard wa-ter or salt water since it is harmful to the en-
gine.
If water has been used instead of coolant, re-
place it with coolant as soon as possible,
otherwise the cooling system will not be pro-
tected against frost and corrosion.
If water has been added to the coolant, have
a Yamaha dealer check the antifreeze con-
tent of the coolant as soon as possible, oth-
erwise the effectiveness of the coolant will
be reduced.
6. Close the coolant reservoir cover.
7. Install the seat.
NOTE:
If the engine overheats, see page 8-51 for further
instructions.
EBU23521
To change the coolant
WARNING
EWB01890
Wait for the engine and radiator to cool before
removing the radiator cap. You could be
burned by hot fluid and steam blown out under
pressure. Always place a thick rag over the cap

7. After draining the coolant, thoroughly flush the
cooling system with clean tap water.
8. Replace the coolant drain bolt washers if they
are damaged, and then tighten the coolant
drain bolts to the specified torque.
9. Connect the coolant reservoir hose.
10. Pour the recommended coolant into the reser-voir to the maximum level mark, and then in-
stall the reservoir cap.
11. Pour the recommended coolant into the radia-
tor until it is full.

Engine overheating
WARNING
EWB02290
Wait for the engine and radiator to cool before removing the radiator cap. You could be burned by
hot fluid and steam blown out under pressure. Always put a thick rag over the cap when opening.
Allow any remaining pressure to escape before completely removing the cap.
NOTE:
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the rec-
ommended coolant as soon as possible.
Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer check
and repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again, have a
Yamaha dealer check and repair the cooling system.
There is
leakage.
There is
no leakage.
