safety devices. If the safety devices are
damaged, consult your local dealer for
replacement.Always use seat belts.
①Roll-over protective structure；
②Seat belts；
4. Do not wear loose articles of clothing during

parts on the vehicle and could cause a severe
injury to occur.
You should always wear protective equipment,
such as helmet, boots, eye protection, ear
protection, and gloves etc.
5. Only a qualified driver should operate this UTV.

（2）Check brakes, throttle, brake pedal
and other mechanical parts for proper
operation. If you discover any
irregularities, replace related parts as
necessary. Periodically check the
fittings and fasteners.
（3）Check engine oil level and engine
coolant level.
（4）Check that the UTV is equipped to
handle the surroundings.
（5）Check and keep vehicle clean. Sludge,
grease and debris can cause a fire

and cause injury.

SAFE OPERATION 1-2
2) This UTV is designed and manufactured for
off-road use only so never drive on paved
roadways.
2. Operation
1. Start the engine only in an open ventilated
area. Carbon monoxide is colorless, odorless
and is emitted from the engine and can cause
death in areas with poor ventilation.
2. Never start the vehicle or operate the gear
selector unless seated in the driver’s seat.
3. Never start the engine until the gear select
lever is placed in “N” position and the brake is
in the brake position.

engine, especially driving on rough terrain as
this can cause injury or death. Press the
accelerator pedal slowly.
8. Drive at slow speeds before braking.
9. With the differential unlocked (DIFF.LOCK is
off) when pressing the accelerator, the
front/rear wheels can turn at different speeds
to assist in the stability of the vehicle.
10. Never drive over terrain such as a ditch, a hole,
dams, excessive mud, or the vehicle can get
stuck because of the vehicles weight.
11. Always pay close attention to your
surroundings, and check for streets, trail
intersections or other obstacles.

Turn off the engine and remove the key when
children are in the operating area. Never carry
children in the cargo area. This is very dangerous

slope, you should use the parking brake and then
remove the key.

SAFE OPERATION 1-3
4. Driving on a slope
Be cautious when riding on a slope, as this is the
main reason for loss of control, and overturn,
leading to severe injury or even death.
1. Drive in a straight line on a slope at a
low-speed.
2. Reduce weight when ride on a slope or rough
terrain.
3. Avoid sudden application of the brakes when
you go uphill or downhill. Be more careful
when vehicle turns on a slope.
4. If you start to lose momentum or need to park
when climbing, use the hand lever brake to
come to a stop. Release the brake and begin
to coast down the hill.
5. If do not believe you can operate the UTV
safely in reverse do not attempt to ascend the
slope any further.
6. Riding in mud, a ditch, and on slopes will
increase the risk of an overturn. Be more
cautious when operating in 4WD, vehicle
traction will increase and it is easy to misjudge
for vehicle’s ability to climb a grade.
7. Drive gradually and slowly when climbing.
Avoid suddenly changes of vehicle speed or
direction.
5. Driving in harsh conditions
1. Vehicle can be operated during the day or
under good light conditions.
2. Under all conditions, both operator and

water.（water depth should not exceed axle
height）
6. Driving at high speed
1. Check for front/rear wheel condition.
2. Slow down when turning. Turning at high
speed may result in overturn or even death.
3. Turn on your headlights at high speeds.
4. Drive only when the vehicle speed can be
controlled.
5. Do not use DIFF.LOCK when driving at high
speeds. This may cause loss of control of the
vehicle.
6. When driving at high speeds, sudden turning
of the steering wheel will reduce vehicle
stability. Never sharply turn the steering wheel
at high speeds.
7. Instructions for carrier
1. Never carry a passenger in the cargo area.
2. Evenly distribute the cargo to maintain proper
stability. Avoid overloading the carrier. Cargo
should be securely attached.
3. Reduce loaded weight when driving on poor
road conditions or on steep inclines.
4. Only the driver should be in the seat when
operating the hydraulic dump mechanism (if
applicable). Once lowered, lock the cargo bed
in place before operating the vehicle.
5. Do not put your hands or your body under the
cargo bed when the carrier is lifted (if
applicable). Avoid driving before securing and
locking the cargo bed.

9. Transportation
1. Avoid dragging the vehicle behind another
vehicle. Use a trailer or truck to transport the
vehicle.
2. When loading or unloading, pay attention to
your surroundings and others in the area.
8. Maintenance
Stop the vehicle and park it on level ground. Pull
the parking brake and remove all cargo. Then
place shift lever on “N” position, stop the engine
and remove the key.
1. When working next to the engine, exhaust, or
radiator, work only after it has cooled down.
2. Wait for the engine to stop running and cool
down before checking the coolant level.
Otherwise, you could be burned by hot fluid or
steam.
3. No smoking when adding electrolyte or
refueling. The fuel tank and battery should be
kept away from sparks. The Battery produces
hydrogen and oxygen during charging and this
could accelerate the risk of explosion.
4. Read and follow the instructions before
replacing the battery.
5. During maintenance, first aid kits and fire
extinguishers should be placed at your
fingertips.
6. During maintenance, you should disconnect
the battery cables.
①Battery
7. Do not open the radiator cap before the
coolant has cooled down. When the coolant is
cold, open slowly and let the coolant pressure
reduce, and then open radiator cap. Check for
the coolant level in the coolant reservoir. If
necessary, add coolant.
8. Tires should be mounted on rims with special
equipment, only by professionals.
9. Keep the specified tire pressure to ensure
