BATTERY
Open the seat with the key to reach the battery.
The terminal block should be checked, together with the actual ter-
minals themselves.
If any oxide is observed on the terminal block or the ends of the
terminals, this should be cleaned off with a metal bristle brush,
sandpaper or similar. Once the cleaning operation has been com-
pleted, the terminals should be connected again and grease
applied to their ends and the terminal block.
Correct connection must be verified, otherwise the battery could
be damaged.
Special attention should be applied to battery handling, since this
contains sulphuric acid and you may run the risk of burning your
skin, eyes and clothing. It should also be kept away from flames, sparks and cigarettes.
If it should ever become necessary to replace the battery, then the same battery type should be fitted.
FUSE
L'installazione ha un fusibile, per aderire a questi è dovuta per rimuovere la sella e per smontare il piat-
to laterale di sinistra. Il fusibile è di 15 ampèri. Se il fusibile salta, spenga il motore e sostituiscalo con
uno degli stessi ampèri.

PETROL TANK
To access the petrol tank, open the filling cap and to turn the key
in an anticlockwise direction.
Only oil-free petrol should be used.
The fuel tank capacity is 6,3 liters.
REMEMBER: unleaded petrol must always be used.
12
CHOKE CONTROL
The choke control is over the clutch lever. When the engine is cold,
the lever should be driven and once the engine is running, it should
be to wait for seconds before loosen to its original position (he is
possible to circulate several minutes with control to starter action).
Prolonged use of the choke once the engine is running
could lead to poor engine performance.

PETROL TAP
The petrol tap is on the left, under the fuel tank.
It has three positions:
OFF: Fuel supply is cut-off in this position. The control should be
set to this position when the engine is not running.
ON: Fuel is supplied to the carburettor in this position. Normal
driving is performed with the lever in this position.
RES: This is the RESERVE position. If you run out of fuel with the
lever in the ON position, then it should be moved to this position.
The tank should be refilled as soon as possible, remembering to
return this control to the “ON” position.

CHECKS TO BE CARRIED OUT BEFORE OPERATING
The following should be checked before using your motorbike:
Items to check Checks
Lights and indicators Check for correct operation
Front and rear brakes Check both free-play and operation
Accelerator grip Check free-play, adjust and lubricate as necessary
Petrol tank Check level and refill as required
Tyres Check pressure, wear and general condition
Indicator lights Check for correct operation
Clutch Check both free-play and operation.
Transmission chain Check tension and condition
Battery Check its operation Charge where necessary
These checks before use should be carried out each time the motorbike is used.
A complete check-out requires no more than a few minutes.
If any problems are detected during the checks, these must be corrected before the motorbike is used.

ROUTINE CHECKS
FRONT BRAKE
The front brake consists of a 260 mm dia-
meter disc brake, which is operated by
means of a double-piston radial clip and
hydraulic pump.
The braking surface should be free from
both grease and dirt to ensure perfect ope-
ration. The following procedure should be
followed if you find it necessary to empty
and the refill the brake fluid circuit.
Remove the pump cover and fill almost
completely with brake fluid.
The loosen the bleeding nit and fit a piece
of tubing (for petrol) to this same nnut.
It is recommended that this tube is inserted into some form of container so that there is no spilled fluid.
With the liquid in the pump and the bleeding nut loose, slowly operate the lever until the liquid drops and
exits the tube without any air bubbles. At this point, close the bleeding nut and refill the tank with brake
liquid to the halfway mark. Close the cover and operate until perfect braking is achieved. Check the brake
liquid level through the view-port on the brake pump. Refill if necessary.

Manual TANGO 250-ING Feb09.qxp 09/06/2009 9:22 Página 15

REAR BRAKE
Check the oil level on a regular basis. It should never be allo-
wed to drop below the lower mark on the tank which is located
above the brake pump and underneath the right-hand side num-
ber plate. Only hydraulic oil for brakes should be employed to
fill this tank.
When the brake travel is made empty, the system should be pur-
ged at one of our service centres.
BRAKE PUMP AND PADS
Verify the brake fluid level, if it is not correct, the tank should be
refilled to the correct mark. If the hydraulic clip brake pads are
worn, they must be replaced.
The minimum thickness of the Ferodo pads is 2 mm.
16
Please remember that these operations should be carried out by an official RIEJU ser-
vice centre.

ACCELERATOR GRIP
Check for correct operation by rotating the grip
and verifying correct free-play.
The grip should firmly return when the accelerator
is released.
LIGHTS AND INDICATORS
Check that all headlights, road lights, indicator
lights, rear lights and indicator lamps operate
correctly.
TYRES
Tyre pressure has a direct influence on machine stability and comfort with respect to braking, and above
all on user safety, therefore tyre pressure should be regularly checked and maintained. Check that the rim
is centred and also inspect for tyre wear. Do not overload the motorbike as this will lead to a loss of sta-
bility and excessive tyre wear.
WARNING: If tyre pressure is
very high, they lose their shock-
absorbing capabilities and all the
effects of uneven roads will be
directly transmitted to the chas-
sis, with negative consequences
on both safety and comfort.

ENGINE STARTING AND OPERATION
It is very important that you have full knowledge of your motorbike and how it works.
WARNING: The engine should never be left running in an enclosed space because the toxic exhaust
fumes could have serious consequences on your health.
STARTING THE ENGINE
Open the petrol tap.
If the engine is cold, use the choke, which is located next the carburettor over the clutch lever.
Turn the ignition key in a clockwise direction, check that the engine is in neutral, fully close the accelera-
tor grip and press the electrical start push-button.
Remember that the electrical starter motor must not be engaged for more than five seconds at a time.
A few seconds after the engine starts up the choke should be returned to its original position.
Then press the clutch lever and engage first gear, progressively releasing the clutch lever as the accele-
rator is smoothly operated.
Do not fully accelerate or operate the engine at a high rev count until it is sufficiently heated-up.
WARNING: Before actually moving off, you should always allow sufficient time for the
engine to heat up and should never strongly accelerate with the engine cold. This will
guarantee longer engine life.
