SAFETY INFORMATION
THE SAFETY IS FRIST. Severe injury or death can result if you do not follow
these instructions。Read this manual and all labels carefully and follow the operating
procedures described:
1. This vehicle is designed to carry the driver and one passenger. Never carry
passengers in the cargo bed.
2. Always be sure the driver and passenger are wearing seat belts.
3. Never give a ride to a passenger who is too small to reach and hold the handgrip
on the enclosure.
4. Always avoid operating the vehicle on any paved surfaces, including sidewalks,
driveways, parking lots, and streets.
5. Never operate this vehicle on any public street, road, or highway, even a dirt or
gravel one.
6. Never operate this vehicle without wearing an approved motorcycle helmet that
fits properly. You should also wear eye protection (goggles or a face shield), gloves,
over-the-ankle boots, long-sleeved shirt or jacket, and long pants.
7. Never consume alcohol or drugs before or while operating this vehicle.
8. Never operate at speeds too fast for your skills or the conditions. Always go at a
speed that is proper for the terrain, visibility, operating conditions, and your
experience.
9. Never attempt jumps or other stunts.
10. Always inspect your vehicle each time you use it to be sure it is in safe
operating condition. Always follow the inspection and maintenance procedures and

20
schedules described in this manual.
11. Always keep both hands, arms, feet, and legs inside the vehicle at all times
during operation. Keep your feet on the floorboard. Never hold onto the enclosure
except when using the handgrip inside the enclosure. Otherwise, your hand could be
injured if it is caught between the enclosure and an obstacle outside the vehicle.
12. Always keep both hands on the steering wheel when driving.
13. Never wrap your thumbs and fingers around the steering wheel. This is
particularly important when driving in rough terrain. The front wheels will move right
and left as they respond to the terrain, and this movement will be felt in the steering
wheel. A sudden jolt could wrench the steering wheel around, and your thumbs or
fingers could be injured if they are in the way of the steering wheel spokes.
14.Always go slowly and be extra careful when operating on unfamiliar terrain.
Always be alert to changing terrain conditions when driving the vehicle.
15. Never operate on excessively rough, slippery, or loose terrain until you have
learned and practiced the skills necessary to control the vehicle on such terrain.
Always be especially cautious on these kinds of terrain.
16. Never turn at excessive speed. Practice turning at slow speeds before attempting
to turn at faster speeds. Do not attempt turns on steep inclines.
17. Never operate the vehicle on hills that are too steep for it or for your abilities.
Go straight up and down hills where possible. Maximum slope angle: 15º .
18. Never operate on hills that are slippery or ones where you will not be able to
see far enough ahead of you. Never go over the top of a hill at speed if you cannot see
what is on the other side.
19. Always follow proper procedures for going uphill. If you lose momentum and
cannot continue up a hill, back down the hill with the engine in reverse gear. Use
engine braking to help you go slowly. If necessary, use the brakes gradually to help
you go slowly.
20. Always check terrain carefully before going down hills. Go as slowly as
possible. Never go down a hill at high speed.
21. Always check for obstacles before operating in a new area.
22. Never operate the vehicle in fast flowing water or water deeper than the
floorboards on this model. Remember that wet brakes may have reduced stopping
ability. Test your brakes after leaving water. If necessary, apply them several times to
let friction dry out the linings.
23. Always be sure there are no obstacles or people behind you when you operate in
reverse. When it is safe to proceed in reverse, go slowly. Do not brake abruptly when
carrying loads in the cargo bed.
24. Always use the size and type of tires specified in this manual.
25. Always maintain proper tire pressure as described in this manual.
26. Never exceed the stated load capacity. Cargo should be as far forward in the bed
as possible, and distributed evenly from side to side. Be sure cargo is secured so that it
cannot move around during operation. Reduce speed and follow instructions in this
manual for carrying cargo or pulling a trailer. Allow greater distance for braking.
