- Always perform the routine checks described in this manual before
using the QUAD, to make sure it is in perfect operating condition,
- Riding a QUAD is not like driving any other vehicle, especially
when cornering. Practise on flat, open ground free from obstacles
and other vehicles.
Read the recommendations made by this manual in the section "Use
of the QUAD".
- The same applies to steep climbs or descents. Start practicing with
minimum slopes and raise the difficulty little by little. Advice about
this is also included in the section mentioned above.
- In case the engine stalls, follow the procedure described in this
manual. If the engine stalls and the vehicle starts rolling backwards,
follow the special braking procedure described in this manual. Get
off the vehicle to the higher on the slope than the vehicle. Remember
that your safety comes before that of the machine, and it is important
to keep this priority in mind.
- When traversing a slope, move your weight to the uphill side; read
the manual regarding this. Avoid excessively slippery slopes or loose
surfaces.
- Never try to overcome big obstacles, like rocks or trunks. This
vehicle has not been designed for this purpose; you may damage
the vehicle and/or cause injury to yourself.
- Do not try to make the vehicle slide sideways if you don't master
this technique; this is a particularly dangerous manoeuvre. Like in
the cases described above, do some testing on flat, wide, obstacle-
free ground beforehand and follow the advice given in this manual.
You must never lose control of the vehicle.
SAFETY INFORMATION
The QUAD is not a toy: driving it can be dangerous.
The QUAD is driven differently form from other vehicles such as
cars and motorbikes. Even during routine manoeuvres like turns,
driving on slopes or over obstacles, collisions or tumbles can occur
if the correct precautions are not taken.
WARNING
If these instructions are not heeded, you may suffer serious injury
or even loss of life.
- Do not drive the QUAD before reading the following sections:
"Safety information", "Use of the QUAD", and "Main parts of the
vehicle". Even if you are an experienced QUAD driver, not all makes
and models are equal and it is necessary to know the machine in
depth before starting on your first outing.
- You are not allowed to carry a passenger, and the vehicle is not
equipped for that purpose.
- Sit correctly with both hands on the handlebars, your feet on the
footrests and your back straight up.
- Always control your speed according to your skills, the weather
and ground conditions.
- Pay attention to surface changes and control your speed when
you are not familiar with these conditions.

-9-
- This vehicle has been designed to go through water no deeper
than 35 cm. Do not use the vehicle in fast moving water; carefully
read the instructions regarding this type of terrain. Take into account
that braking efficiency is diminished when the brakes are wet. When
coming out of the water, brake several times so that they dry more
quickly by friction.
- Always use the tyre size and type described in this manual.
WARNING
- Always stop the engine before and during refuelling.
- While refuelling, do not smoke, fuel is highly flammable and may
explode under certain conditions. Keep the engine off at all times.
Make sure the area is well ventilated and free from any source of
flame or sparks; this includes any appliance with a pilot light. The
fuel might catch fire causing burns. Avoid spilling fuel over the engine,
exhaust or silencer.
- When transporting a quad with a trailer, ensure it is always vertical.
- Fuel is poisonous. In case of accidental ingestion, abundant vapour
inhalation or contact with eyes, seek medical help immediately. If
fuel comes in contact with your skin, wash it with soap and water.
If fuel is spilled on clothes then change them.
- Always ride your QUAD in well-ventilated areas. Do not start the
engine or keep it running in enclosed areas. The exhaust vapour is
poisonous and may lead to loss of consciousness or even death in
a short time.

THROTTLE GRIP
Before starting the engine, check that the throttle works smoothly
(I). Make sure it slides smoothly back to idle when the grip is released.
The grip has a return spring that puts the engine to idle and slows
the QUAD down when the control is released.
WARNING
If the throttle is not working properly, it may be difficult to accelerate
or decelerate as desired. This could result in an accident. Check
the correct operation of the throttle before starting the engine. If the
throttle does not work smoothly then find the cause. Solve the
problem before using the machine, or go to a specialised workshop.
CLUTCH LEVER

BATTERY
This battery is maintenance free and checking the fluid level is not
required. It is advisable to check the charge of the battery periodically
The operating instructions for the battery are as follows:
1.  Check the battery tension in open circuit status (disconnected).
2.  In case the battery's tension is below 12.60 V, or if the storage
period has exceeded 6 months, the battery has to be recharged
following the instructions in paragraph 3.2.
If the battery voltage is above 12.60 V, the battery can be installed on 
the vehicle without having to recharge it.
3.1. Constant voltage charge mode.
- Constant voltage = 14.40 – 14.7 V
(A)

-18-
CAUTION
Not using the standard manner of charging may seriously shorten
the battery life.
Never exceed the standard charge.
CAUTION
Inverting the polarity of the battery terminals may cause battery charge
problems and cause damage to the battery system.
The red terminal is positive (+) and the black terminal is negative (-).
- Initial charge current = 0.1 – 0.5 Cn
- Charge duration = 6 hours minimum / 24 hours maximum.
3.2. Constant power charge mode.
- Maximum charge current = 0.1 Cn
- Recommended charge time = 5 - 8 hours.
- The product (charge current) X (charge duration) must be within the 
range: 0.5 – 0.8 Cn
NOTE
In the case that a different mode of charging is used to those
established here, never exceed the maximum allowed currents
nor the maximum charge duration of 24 hours.
FRONT GUARD
The front guard juts out from the QUAD assembly. In case of a frontal
collision, the protection, attached directly to the frame, will absorb
the impact and protect the steering and the rest of the vehicle from
significant damage.
REAR GUARD
Likewise, the rear guard (D) also protrudes from the vehicle. This
guard prevents the QUAD from falling over backwards, which might
result in serious injuries.

-19-

Check that the brake pedal height is correct. If not, have it adjusted
at a specialised workshop.
Check the operation of the lever and pedal. They must move smoothly
and must feel firm when the brakes are applied. Otherwise, have a
specialised workshop inspect the vehicle.
Brake liquid level
Check the brake liquid level. Add liquid if necessary. (See the
Maintenance section of the manual)
Recommended fluid D.O.T 3 or D.O.T 4
NOTE
The fluid issued at the manufacturers is D.O.T.4.
Brake liquid leaks
Check for brake fluid leaks in the brake line joints or fluid reservoirs.
Apply the brakes firmly for about one minute. In case of a leaking,
have a specialised workshop inspect the vehicle.
VERIFICATIONS TO BE MADE BEFORE STARTING THE
VEHICLE
WARNING
Always inspect the QUAD before use, to ensure it is safe to operate
without any danger.
Always follow the inspection and maintenance procedures and
programs described in this manual. Failure to inspect the machine
increases the risk of accident or breakdown.
FRONT AND REAR BRAKES
WARNING
Before driving, always check the brakes. Do not drive the QUAD
there is any braking problem or if a loss in braking capacity is
possible, this could result in an accident. If there is any problem that
cannot be solved using the procedures described in this manual, go
to a specialised workshop to have the QUAD checked.
Disc and disc pad wear is automatically compensated for and has
no effect on the brake lever or pedal action. So there are no parts
that require adjustment on the brakes except brake lever play and
the brake pedal position and play.
Brake lever and pedal
Ensure that there is no play in the front brake lever (1). If so, check
the condition of the brake pads and consult the “Adjustments and
maintenance” section.
Check there is no free play in the front brake lever (2).
