low, “LO” will be displayed. When the coolant
temperature rises, the coolant temperature
display will begin to flash. If the coolant tem-
perature continues to rise, the message “HI”
will flash.TIPThe coolant temperature display can be set
to “°C” or “°F”. To switch the temperature
units, turn the key to “ ” (off), then hold
the “RESET” button pushed and turn the
key to “ ” (on).
 The radiator fans turn on and off automati-
cally according to the coolant temperature.
Fuel gauge
The fuel gauge indicates the amount of fuel in
the fuel tank. The display segments of the fuel
gauge disappear from “F” (full) towards “E”
(empty) as the fuel level decreases. When the
last segment on the left flashes, refuel as
soon as possible.1. Fuel gauge

4. Install the differential gear oil drain boltand its new gasket, and then tighten the
bolt to the specified torque.
5. Refill the differential gear case with the recommended oil.
6. Check the oil filler bolt gasket for dam- age, and replace it if necessary. 7. Install the differential gear oil filler bolt
and its gasket, and then tighten the bolt
to the specified torque.
8. Check for oil leakage. If oil leakage is found, check for the cause.

it with coolant as soon as possible,
otherwise the cooling system will not
be protected against frost and corro-
sion. If water has been added to the
coolant, have a Yamaha dealer check
the antifreeze content of the coolant
as soon as possible, otherwise the ef-
fectiveness of the coolant will be re-
duced.

6. Install the panel when finished servicing
the vehicle. To change the coolant
The coolant must be changed at the intervals
specified in the periodic maintenance chart.
Have a Yamaha dealer change the coolant.
WARNING! Never attempt to remove the
radiator cap when the engine is hot.

NOTICEECB00641To prevent accidental short-circuiting,
turn off the main switch when checking or
replacing a fuse. 2. Remove panel A. (See page 9-10.)
3. Remove the blown fuse, and then install anew fuse of the specified amperage.
WARNING! Always use a fuse of the specified amperage. Never use any
material in place of the proper fuse.
Using an improper fuse can cause
damage to the electrical system and
may lead to a fire.

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIP Tap water can be used in an emergency. Ch ange to the recommended coolant as soon as
possible.
 The engine will tend to overheat if the radiator is caked with mud, or if air was not properly bled
from the cooling system. Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.

The figures quoted are emission levels and
are not necessarily safe working levels. Whilst
there is a correlation between the emission
and exposure levels, this cannot be used reli-
ably to determine whether or not further pre-
cautions are required. Factors that influence
the actual level of exposure of work-force in-
clude the characteristics of the work room,
the other sources of noise, etc. i.e. the num- ber of machines and other adjacent process-
es, and the length of time for which an
operator is exposed to the noise. Also the
permissible exposure level can vary from
country. This information, however, will en-
able the user of the machine to make a better
evaluation of the hazard and risk.UB5J7CE0.book Page 6 Thursday, November 26, 2020 1:37 PM
