FOR YOUR SAFETY – PRE-OPERATION CHECKS
EAU15596
Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always follow the inspection
and maintenance procedures and schedules described in the Owner’s Manual.
WARNING
EWA11151
Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equipment damage.
Do not operate the vehicle if you find any problem. If a problem cannot be corrected by the procedures provided in
this manual, have the vehicle inspected by a Yamaha dealer.
Before using this vehicle, check the following points:
ITEM CHECKS PAGE
Fuel
●
Check fuel level in fuel tank.
●
Refuel if necessary.
●
Check fuel line for leakage.3-14
Engine oil
●
Check oil level in engine.
●
If necessary, add recommended oil to specified level.
●
Check vehicle for oil leakage.6-8
Coolant
●
Check coolant level in reservoir.
●
If necessary, add recommended coolant to specified level.
●
Check cooling system for leakage.6-11
Front brake
●
Check operation.
●
If soft or spongy, have Yamaha dealer bleed hydraulic system.
●
Check brake pads for wear.
●
Replace if necessary.
●
Check fluid level in reservoir.
●
If necessary, add recommended brake fluid to specified level.
●
Check hydraulic system for leakage.6-19, 6-20

10. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking, im-
mediately turn the engine off and
check for the cause.
11. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU20070
Coolant
The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU38583
To check the coolant level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.
TIP
●
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
●
Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.
TIP
The coolant should be between the
minimum and maximum level marks.
For TDM900
For TDM900A
3. If the coolant is at or below the
1. “CD” specification
2. “ENERGY CONSERVING II”

minimum level mark, remove pan-
el B for TDM900 or panel A for
TDM900A (See page 6-6.), re-
move the reservoir cap, add cool-
ant to the maximum level mark,
and then install the reservoir cap
and the panel.
WARNING! Re-
move only the coolant reservoir
cap. Never attempt to remove
the radiator cap when the en-
gine is hot.
[EWA15161]
NOTICE:
If
coolant is not available, use dis-
tilled water or soft tap water in-
stead. Do not use hard water or
salt water since it is harmful to
the engine. If water has been
used instead of coolant, replace
it with coolant as soon as possi-
ble, otherwise the cooling sys-
tem will not be protected
against frost and corrosion. 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 effectiveness of
the coolant will be re-
duced.

Replacing the air filter element
The air filter element should be re-
placed at the intervals specified in the
periodic maintenance and lubrication
chart. Replace the air filter element
more frequently if you are riding in un-
usually wet or dusty areas.
1. Remove the seat. (See
page 3-16.)
2. Remove cowlings A and B as well
as panels A and B. (See
page 6-6.)
3. Remove the fuel tank bolts.
TIP
For TDM900, skip steps 4 and 12.

WARNING
EWA10400
●
Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
●
After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hissing
sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.
TIP
If coolant is not available, tap water can be temporarily used instead, 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
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See TIP.)
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.
