PRE-OPERATION CHECKS
EBU19220Pre-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 aYamaha dealer.
ITEM ROUTINE PAGE
FuelCheck fuel level in fuel tank, and add recommended fuel if neces-
sary.
Check fuel line for leakage. Correct if necessary.4-16, 5-3
Engine oilCheck oil level in engine, and add recommended oil to specified lev-
el if necessary.
Check ATV for oil leakage. Correct if necessary.5-3, 8-22
Final gear oilCheck ATV for oil leakage. Correct if necessary. 5-3, 8-26
Differential gear oilCheck ATV for oil leakage. Correct if necessary. 5-3, 8-28
CoolantCheck coolant level in reservoir, and add recommended coolant to
specified level if necessary.
Check cooling system for leakage. Correct if necessary.5-3, 8-30
Front brakeCheck operation. If soft or spongy, have Yamaha dealer bleed hy-
draulic 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, 8-44, 8-46, 8-48

8 5. Add the recommended differential gear oil to
the brim of the filler hole as shown.
CAUTION:ECB00410Be sure no foreign material enters the differen-tial gear case.
6. Install the oil filler bolt, and then tighten it to the
specified torque.
7. Check the differential gear case for oil leak-
age. If oil is leaking, check for the cause.EBU23470Coolant 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.EBU27122To check the coolant level
1. Place the ATV on a level surface. Tightening torque:
Differential gear oil drain bolt:
10 Nm (1.0 m·kgf, 7.2 ft·lbf)
1. Differential gear oil
2. Differential gear oil filler bolt
3. Correct oil levelRecommended differential gear oil:
See page 10-1.
Tightening torque:
Differential gear oil filler bolt:
23 Nm (2.3 m·kgf, 17 ft·lbf)

8 8. After draining the coolant, thoroughly flush the
cooling system with clean tap water.
9. Replace the coolant drain bolt washer if it is
damaged, install the coolant drain bolt, and
then tighten it to the specified torque.
10. Connect the coolant reservoir hose.
11. Pour the recommended coolant into the radia-
tor until it is full.12. Pour the recommended coolant into the reser-
voir to the maximum level mark, and then in-
stall the reservoir cap.
CAUTION:ECB00401If 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.

8 18. When coolant begins to flow out of the bolt
hole, tighten the cylinder head air bleed bolt to
the specified torque.
19. Start the engine and let it idle for ten minutes.
20. Rev the engine five times.
21. Pour the recommended coolant into the radia-
tor until it is full.22. Stop the engine and allow it to cool. If the cool-
ant level has dropped after the engine has
cooled, add sufficient coolant until it reaches
the top of the radiator, and then install the ra-
diator cap.
23. Start the engine, and then check for coolant
leakage.
NOTE:If any leakage is found, have a Yamaha dealercheck the cooling system.
24. Install the V-belt cooling duct, and then tighten
the clamp screw.
25. Install the panels.EBU27800Cleaning the air filter element The air filter element should be cleaned at the in-
tervals specified in the periodic maintenance and
lubrication chart. Clean the air filter element more
frequently if you are riding in unusually wet or dusty
areas.NOTE:There are two check hoses at the bottom of the air
filter case, which are located behind panels D and
E. (See page 8-8 for an explanation on removing
