EXHAUST SYSTEM
GMX Motorbikes advise that the exhaust on the machine can become very hot during and following operation. To prevent
burns, avoid touching the exhaust system. Park the machine in a place where Pedestrians or children are not likely to come
in contact.
FUEL HANDLING
Precautions should be taken when handling any type of petrochemicals. Gasoline can catch re, and is toxic to life and the
environment. GMX motorbikes recommend the following safety tips to avoid accidents, injury/death:
- Always turn o the engine when re-fuelling. Do not refuel right after the engine has been running and is still very hot.
- Do not spill gasoline on the engine or exhaust pipe/muer when refuelling.
- Never refuel in any proximity to any sources of ignition such as smokers, open ames or embers etc.
- When transporting the machine in another vehicle, be sure it is kept upright and that the fuel cock is in the “OFF” position.
Otherwise, fuel may leak out of the carburettor or fuel tank.
- Gasoline is poisonous and can cause injuries, in the case of swallowing gasoline, inhaling gasoline vapours or contact with
eyes, see your doctor immediately.
- In the case of gasoline contact on your skin, wash with soap and water. If gasoline spills on your clothing, change your clothes.

FILLING THE TANK
The fuel tank capacity is 3.0Ltr in total (including the reserve). Open the fuel cap by unscrewing it, and carefully ll the tank
within a viewable level.
PRECAUTION: Do not overow the fuel tank, lling should be accomplished using a fuel funnel to avoid spills
(please refer to the safety and precautions section of your manual)
Operating the Fuel Tap
The fuel tap is designed as a safety feature to be able to isolate the supply of fuel to the system.
ON: When the fuel lock is in the “ON” position, the fuel circuit is open and in full supply.
OFF: When the fuel lock is in the “OFF” position, the fuel circuit is closed. This is recommended when the bike is not in use.
STARTING THE ENGINE
Warning: Never operate this engine or any engine in an enclosed space. Failure to operate combustion engines
with correct ventilation can result in Carbon monoxide poisoning and even death by suocation.
Set the key into the ignition and turn clockwise.
Set the Kill switch in the “ON” position.
Ensure the vehicle has an appropriate amount of fuel
Set the fuel tap into the “ON” position.
When cold ensure the kill switch on the left handle grip is in the “ON” position.
Open the choke by moving the choke handle up
Rotate the throttle 1/8 for extra fuel injection.

Kick down hard on the kick start, releasing immediately (failure to remove your foot from the kick start can damage the starting
mechanism). Where the model has an electric start, push the starter button until the engine has started (do not hold down the
button for more than 5 seconds at a time as this may damage the battery).
Twist the throttle to keep the revs of the engine up whilst the engine reaches optimum operating temperature.
Once the engine is at running temperature, turn the choke handle all the way down (closed position)
PLEASE NOTE: Warm up the engine for 3-5mins prior to each usage. Over revving the engine is harmful to the engine, especially
when cold. The running in of the engine is considered to be for the rst 500km, during this time avoid steep inclines and high
speeds. Avoid over revving the engine at all times.
Turning o the engine
In a stand still position, in neutral gear, remove your grip on the throttle
Turn the kill switch into the “OFF” position, followed by the key ignition.
Set the fuel tap into the “OFF” position.
PLEASE NOTE: In an emergency release the throttle, hold in the clutch and turn “OFF”the kill switch. Slow down as quickly as is
safe to do so.

GMX Motorbikes promote safety as paramount. As such, it is advised that before each and every use of your OFF ROAD VEHICLE
that you actively walk around your vehicle and check that everything appears in order. Maintenance should be undertaken
regularly and servicing should be carried out by the appropriate persons. GMX recommend any work being carried out on any
of our range of OFF ROAD VEHICLE’S should be done by an approved mechanic.
The following list has been provided for you by GMX Motorbikes as an advisory process before each ride. This should be
completed at the discretion of the rider and any faults discovered during the checklist should be FULLY resolved before
riding the OFF ROAD VEHICLE.
FRONT AND REAR BREAKS
When checking the breaks, ensure all cables are in place and there are no leaks. Check the breaking mechanism works
manually before riding. Some brakes are adjustable for performance reasons; brake adjustments are sensitive and in the
interest of safety should only be carried out by a skilled mechanic.

FUEL LINE AND TANK
It is important to check for any fuel leaks around the tanks and along fuel lines. OFF ROAD VEHICLE engines become hot
during use and therefore pose a re risk.
OIL LEVELS
Oil Levels Should be checked prior to each usage, the“dipstick”can be found on the right cover of the crack case, much like a car
this is used to check the oil levels, if the engine is low on oil top up to a suitable level. The dipstick should always be replaced
rmly and securely. The oil supplied with the vehicle is transport oil that should be changed after the rst 4 hours of usage.
Replacing the oil
- Remove the“sump plug”
- Drain the oil from the engine
- Replace the sump plug
- Rell the engine with a high quality oil suitable for the engine
PLEASE NOTE: Never maintain the engine when it is hot as this can cause injury, leaks of petrochemicals can cause res,
explosions and even death.

SPARK PLUG
- Remove the coil/lead from the spark plug
- Remove the spark plug with the correct tool
- Clean around the contactors (where the spark is emitted from) or replace the unit
- Ensure the Gap at the contactors is 0.6-0.7mm
PLEASE NOTE: If you do not feel competent to full ANY
maintenance tasks, please consult a qualied mechanic.
AIR FILTER
Check the air lter after each usage of the vehicle. Where applicable
remove the air lter for cleaning
Wash the lter or soak it with an air lter cleaner or machine oil, if the lter is in any way damaged, please source a
replacement lter appropriate for tting to the Carburettor.
CAUTION: Make sure the air lter is correctly tted to the bike; failure to t the lter will result in contaminants entering the
engine and cause fatal damage to the engine components
THROTTLE
The throttle of your vehicle directly aects the speed of your OFF ROAD VEHICLE it should be in perfect working order
before each time you ride your OFF ROAD VEHICLE . Check and ensure that the cable and all mechanical parts included in the
throttle system are moving freely.

The carburettor is also considered part of the throttle system and may also require adjustment. It is not advised to make
adjustments whilst the engine is running. Repeat adjustments whilst the engine id o and test each adjustment afterwards.
To adjust the carburettor:
- Support the vehicle by means of the side stand
- Adjust the idling speed using the adjustment screw (recommended r/min are aprox. 1500 r/min)
PLEASE NOTE: Do not make adjustments to a cold engine as this is the most changeable state of the engines running.
Adjustments should not be made by unqualied persons, if in doubt please consult a qualied mechanic.
CHAIN
It is advisable to visually check the chain of your OFF ROAD VEHICLE before each use. Its general condition is important, there
should be no obstructions to the chain, it should be well lubricated and under the correct tension
LIGHTS

check intermittently Tires can be damaged by rough terrain
In the event of any discrepancies or faults discovered during your safety checks, please contact an approved mechanic.

GENERAL CLEANLINESS
The cleaning of your vehicle can prolong the life of many component parts such as, plastics brakes and frame etc. Jet washing can
cause damage to certain components.
PLEASE NOTE: Some cleaning chemicals can remove oils and lubricants that are vital to the running condition of the OFF ROAD
VEHICLE . It is highly recommended that all lubricated areas are treated with the correct lubricants. Do not use corrosive
detergents for the cleaning of the vehicle. Brakes can be rendered ineective if wet or contaminated with detergents, please
allow for drying time prior to reusing the vehicle after cleaning.
GMX Motorbikes promote the use of safety equipment during the use of your OFF ROAD VEHICLE; the following list is an
advisory guideline of the equipment that should be obtained before using your OFF ROAD VEHICLE for the rst time, and to be
used for every ride regardless of experience and skill level.
HELMET
A helmet is the most important piece of protective equipment and should be worn at all times the vehicle is being ridden.
– Select a helmet that complies with Australian Standards
– Ensure the helmet ts the operator snugly, is securely fastened and provides good,
all-round visibility. A poorly-tting or loose helmet can become dislodged in an incident and then oer no protection at all.
– Operators should not share helmets but instead use personal helmets for size and hygiene reasons.
EYE PROTECTION
Eye protection is recommended to prevent eye injuries and prevent branches, bugs, dust or sand hitting your face and
distracting you. Sunglasses are unlikely to provide adequate physical protection.

GLOVES
Gloves are recommended to provide protection from abrasions and help to keep your hands from getting sore, tired or cold.
Note that rigger’s gloves may become slippery when wet and are not advisable for use with quad bikes.
FOOTWEAR
• Sturdy footwear is recommended (preferably boots that come up past your ankle with strong uppers for
gear changes.)
• Heels will prevent your feet from slipping off the foot decks.
CLOTHING
• Arms and legs should be covered to reduce abrasions to the body, even in hot weather.
• Trousers should be close-tting and in good condition
If you do not intend to use the Vehicle for extended periods of time, it is important to prepare the vehicle correctly for storage
and check the vehicle very carefully prior to putting the OFF ROAD VEHICLE back into service.
PLEASE NOTE: Incorrect storage can cause damage to the working components of the OFF ROAD VEHICLE and in turn
the engine.
- Change the engine oil (Dirty oil can cause damaging sediments to be left in the engine)
- Drain the fuel system entirely and treat the components with a machine oil or anti rust agent (Stale fuel can cause
damage to the carburettor, please refer to the safety precautions for handling petro chemicals)
- Remove the spark plug and inject 20ml of clean engine oil into the cylinder, kick the kick start several times to
distribute engine oil around the top end of the engine. Replace the spark plug ATTENTION: Ensure the ignition is
“OFF”so that the engine cannot re and the spark plug cannot spark)
- Make sure the vehicle is clean, dry and lubricated
- Check tyre pressure and inate where necessary, “Chock”the wheels to avoid misshaping the tyres/tubes.
