TIPThe radiator fan automatically switches on
or off according to the temperature of the
coolant in the radiator.
If the engine overheats, see page 8-67 for
instructions. EBU32400Axle bootsCheck the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.
EBU35121Checking the spark plugsThe spark plug is an important engine com-
ponent which should be periodically
checked, preferably by a Yamaha dealer.
Since heat and deposits will cause any spark
plug to slowly erode, the spark plugs should
be removed and checked in accordance with
the periodic maintenance chart for the emis-
sion control system. In addition, the condition
of the spark plugs can reveal the condition of
the engine.

NOTICEECB00641To prevent accidental short-circuiting,
turn off the main switch when checking or
replacing a fuse. 2. Remove panel A. (See page 8-10.)
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.
TIPIf it is difficult to get the recommended coolant, tap water can be used temporarily, provided that
it is changed to the recommended coolant as soon as possible. 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.UB577AE0.book Page 6 Wednesday, June 8, 2016 9:35 AM
