- Always carry out routine inspections as described in this manual
before going out on the quad bike, to ensure that it is in safe working
condition.
- Driving a quad bike is unlike driving any other vehicle, and you will
particularly notice this when turning. Practice turning first on flat open
ground without any other vehicles in the area.
Read the advice given in the manual in the section -Use of your
QUAD.
- Similarly for steep hills whether you are going up or coming down.
Start by trying gentle slopes and increase the level of difficulty
gradually. Advice is given concerning this aspect in the same section
as mentioned above.
- Follow the procedures described in this manual if the engine stalls.If
the engine stalls and the vehicle begins to roll backwards, follow the
special braking procedure described in this manual
Get off the quad on the up-side of the slope. Remember that your
safety comes first and then that of the machine, it is important to
clearly understand this.
- To cross a slope move your weight towards the rising section, read
the advice in the manual concerning this. Avoid
slopes which are too slippery or with a loose surface.
- Never try to go over large obstacles such as rocks or tree trunks,
the machine is not prepared to do this and you may damage either
you or the machine.
- Do not deliberately skid if you do not know how to do so correctly,as
it could be dangerous. As for the above, first practice on flat open
terrain, without obstacles and follow the advice given in this manual.
You must never lose control of the machine.

SAFETY INFORMATION
THE QUAD is not a toy: its use may be dangerous.
THE QUAD is driven in a different manner to other vehicles, such
as cars or motorcycles. A collision or overturning can happen very
fast, even during routine manoeuvres such as turning, driving on
slopes or over obstacles, unless
the necessary precautions are 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:
"Information concerning your safety", "Use of the QUAD"
and “Principal parts of the QUAD”. Even if you are an experienced
quad bike driver, not all makes and models are the same and it is
imperative to understand the machine well before commencing the
first trip.
- It is forbidden to carry passengers, nor is the bike adapted for this.
- Sit correctly with both hands holding the handle bar, both feet on
the foot rests and your back straight.
- Reduce your speed according to your skill, experience, weather
conditions, or ground conditions.
- Drive with caution over changing ground and reduce speed when
not familiar with the terrain.

- This quad bike is designed to be driven in water with a maximum
depth of 35 cm. Do not use the machine in rapids, read the instructions
about this type of terrain carefully. Remember that when the brakes
get wet, they lose braking capacity. On exiting the water, pump the
brakes several times to dry them more quickly.
- Always use tyres of the size and type described in this manual.
WARNING
- Always switch off the engine when refuelling.
- Do not smoke while refuelling, petrol is highly inflammable and
may be explosive in certain conditions. Always switch off the engine.
Keep the area ventilated and free from naked flames or sparks; this
includes spot light appliances. The petrol could catch fire and cause
burns. Take care not to spill petrol on the engine, exhaust pipe or
silencer.
- When transporting the quad with a trailer, make sure that the quad
is kept in an upright position.
- Petrol is toxic. In the event that petrol is swallowed, excess fumes
are inhaled, or should fuel splash in eyes, seek medical attention
immediately. If petrol spills onto the skin, wash off with soap and
water. If petrol spills onto clothes, change your clothes.
- Always drive the machine in a well ventilated area. Do not start or
run the engine in a closed space. The exhaust fumes are toxic and
can cause loss of consciousness or even death in a very short time.

use of these lights.
THROTTLE TWIST-GRIP
Before starting the engine, check that the throttle spins round smoothly
(I). Ensure that it returns to idle position when the handle is released.
There is a return spring fitted inside the handle which reduces speed
and brings the engine back to idle speed when the throttle handle
is released.
WARNING
If the throttle does not work correctly, it may be difficult to increase
or reduce the speed of the vehicle as desired. This could cause
accidents. Check the throttle is working correctly before starting the
engine. If the throttle does not work smoothly, find out why. Solve
the problem before using the machine, or go to a specialist workshop.
CLUTCH LEVER
The clutch lever is located on the left of the handle bar.
Use the lever to engage and release the clutch (J).
For the clutch to work smoothly, the lever should be tightened quickly
and released slowly.

End (C) is attached to the vehicle and end (D) is securely
attached to the rider.
It consists of an elasticised cable, one end of which is attached to
the vehicle and the other to the rider, in such a way that the end of
the cable which is attached to the vehicle detects any brusque
movement and detaches.
On becoming detached, the engine stops automatically.
NOTE
Make sure that the parking brake has been released before
using the throttle.
We recommend attaching the cable to a resistant point as it is
important that this part of the cable never becomes detached.
(E.g. The cable could be tied to trousers, a jacket, around the
wrist...but always to a resistant point).
WARNING
It is forbidden to use the quad bike before attaching the emergency
stop system. The non-observance of this warning could have serious
consequences.
