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 followed, serious injury or even death
may result.
- 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 the conditions.
- 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.
- Follow the procedures described in this manual if the engine stalls.
If the engine stalls and the vehicle starts rolling backwards, follow
the special braking procedure described in this manual. Get off the
quad on the uphill of the slope. 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. As stated
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.

-9-
- This vehicle has been designed to go through water deeper than
of 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 switch off the engine when 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
petrol could catch fire and cause burns. Avoid spilling fuel over the
engine, exhaust or silencer.
- When transporting the QUAD using a trailer, make sure it is upright
and that the fuel tap is in the OFF position (closed). Fuel leaks might
occur in the carburettor or in the fuel tank otherwise.
- Petrol is toxic. 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 drive the machine in a well-ventilated area.
Do not start or run the engine in a closed space. The exhaust vapour
is poisonous and may lead to loss of consciousness or even death
in a short time.

IMPORTANT INFORMATION
The vehicle leaves the factory with some elements not fitted, in order
to make transportation easier. The dealer will make sure each
element is correctly fitted and you will receive the QUAD ready for
use. Thus, this paragraph is purely for your information.
A carburettor-adjustment kit is included; the adjustments must be
performed by an expert and only when necessary. The carburettor
is already tuned, so setting changes are not initially required.
A tool is also enclosed to adjust the chain and to centre the swing
shaft. Do not lose it; it will be extremely useful.

2 - Swing arm guard. 3 - Footrest assembly.
4 - Foot protectors.
5 - Chain and swing arm
adjustment tool.
6 - Idle jet.

Indicators (F) are located in the lower part of the same left hand side
grip. Note that pushing the switch to the right turns on the right
indicator, and to the left to operate the left indicator.
The button for the horn is located in the same area (G).
HAZARD LIGHTS
The hazard lights are operated by a button (H), located on the front
part of the QUAD, in front of the handlebars. This also works when
the ignition is switched off. When on, a light inside the button will
also flash.
NOTE
Regarding the use of this lights, follow the legal conditions of
each country.
THROTTLE CONTROL
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.
OIL RESERVE INDICATOR
The indicator (J) will light when the oil level is low, that is, when the
reserve level is reached. At this point, there is about 0.75 litres of
oil remaining.
(I)
(H)

EMERGENCY STOP
The QUAD is fitted with an emergency stop system. This prevents
the vehicle from continuing out of control in case the rider should fall
off.
One end (C) is attached to the vehicle and the other end (D) is
secured to the rider.
The cable is elastic. One end is joined to the rider and the other to
the vehicle so that the end of the cable attached to the vehicle is
sensitive to sudden movements and will release.
On becoming detached, the engine stops automatically.
NOTE
Make sure you release the parking brake before operating the
throttle.
FRONT BRAKE LEVER
The front brake lever (A) is located on the right side of the handlebars.
Use the lever to apply the front wheel brakes.
REAR BRAKE PEDAL
The rear brake pedal (B) is located on the right hand side of the
lower chassis. Operate it to apply the brake to the rear wheels.
(A)
(B)
(D)
(C)

-17-
We recommend that the cable is attached to a strong point, so that
it is not accidentally released. (E.g. The cable may be attached to
trousers, jacket, ... to a wrist... but always to a strong support).
WARNING
The use of the QUAD is prohibited without attaching the emergency
stop system. Disregard for this may result in serious consequences.
CHOKE
The choke mechanism (F) is a mechanism that opens the throttle
a fixed amount in case the engine is cold so that there is no need
to operate the throttle grip. The engine will reach its optimal
temperature, in low time and without causing damage.
To use this, pull on the lever (F) upwards, and without operating the
throttle control, start the engine. Note that the engine will start after
a certain number of revolutions.
After just a few seconds, the engine will be at a correct operation
temperature. To release the choke, rotate the throttle control to the
limit and release quickly.
NOTE
If the engine is flooded then start with the throttle fully open.
FUEL TANK CAP
To open the fuel tank, turn the key anti-clockwise.
FUEL CUTOFF
This tap supplies fuel to the carburettor and is located on the right
hand side under the fuel tank. The cut-off has three positions.
(F)

-18-
When the lever (A) is in the centre position (open) then fuel flows
to the carburettor. The machine is normally used with the cut-off in
this position.
C: Closed. With the lever (A) in this position, there is no fuel flow.
Always turn the cut-off (A) to this position when the machine is not
in use.
R: Reserve. This indicates that the fuel reserve is being used. If the
machine runs out of fuel in the ON position then turn the cut-off to
this position.
CAUTION
If the reserve must be used then fill the tank as soon as possible!
Following refuelling put the lever of the cut-off (A) back into the
centre position (open).
SEAT
To remove the seat, use the same key as for the petrol-tank cap
(B).
Insert the key into the lock located on the right hand side of the
QUAD.
(B)
(C)
Turn the key clockwise, and then insert your hand between the seat
and the chassis at the rear of the seat. The seat will lift easily.
NOTE
When putting the seat back in the normal position, ensure it is
secured.
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.
