Dinli DMX 450 Owner's Manual
1
Dear Dinli Quad Users:
Before the delivery of each new vehicle from Dinli factory, the fuel in carburetor is drained off to ensure the
excellent performance and safety of the vehicle. Therefore, when first starting a new vehicle, it is normal to take
20~30 seconds. The quality of each Dinli Quad is guaranteed. Study this manual thoroughly and enjoy your riding
Dinli Quad.
I. PREFACE
WARNING
STOP! If you have the impression that four wheels give you the stability of a car, you are wrong. If you
have the impression that a quad is simple to drive and similar to those other vehicles, that you are
wrong. The risks involved are at least equal to those faced when riding a motorcycle.

● A QUAD IS NOT A TOY AND CAN BE HAZARDOUS TO OPERATE.
● A quad handles differently from other vehicles including motorcycles and cars. A collision or rollover can occur
quickly, even during routine maneuvers such as turning and driving on hills or over obstacles, if you fail to take
proper precautions.
● Severe injury or Death can result if you do not follow these instructions:
01. Read this manual and all labels carefully and follow the operating procedures described.
02. Never operate a quad without proper instruction. Take a training course. Beginners should receive training from
a certified instructor. Contact an authorized quad dealer to find out about the training courses nearest you.
03. Always follow the age recommendation: A child under 16 years old should never operate a quad with engine size
greater than 90cc.
04. Never allow a child under age 16 to operate a quad without adult supervision, and never allow continued use of a
quad by a child if he or she does not have the abilities to operate it safely.
06. Never operate a quad without wearing an approved helmet that fits properly. You should also wear eye
protection (goggles or face shield), gloves, boots, long-sleeved shirt or jacket, and long pants.
07. Never consume alcohol or drugs before or while operating this quad.
08. Never operate at excessive speeds. Always go at a speed that is proper for the terrain, visibility, operating
conditions, and your experience.

10. Always inspect your quad each time you use it to make sure it is in safe operating condition. Always follow the
inspection and maintenance procedures and schedules described in this manual.

13. Never operate on excessively rough, slippery or loose terrain until you have learned and practiced the skills
necessary to control the quad on such terrain. Always be especially cautious on these kinds of terrain.
14. Always follow proper procedures for turning at low speeds before attempting to turn at faster speeds. Do not turn
at excessive speed.
15. Never operate the quad on hill too steep for the quad or for your abilities. Practice on smaller hills before
attempting larger hills.
16. Always follow proper procedures for climbing hills as described in this manual. Check the terrain carefully before
you start up any hill. Never climb hills with excessively slippery or loose surfaces. Shift your weight forward.
Never open the throttle suddenly or make sudden gear changes. Never go over the top of any hill at high speed.
17. Always follow proper procedures for going down hills and for braking on hills as described in this manual. Check
the terrain carefully before you start down any hill. Shift your weight backward. Never go down a hill at high
speed. Avoid going down a hill at an angle that would cause the vehicle to lean sharply to one side. Go straight
down the hill where possible
18. Always follow proper procedures for crossing the side of a hill as described in this manual. Avoid hills with
excessively slippery or loose surfaces. Shift your weight to the uphill side of the quad. Never attempt to turn the
quad around in any hill until you have mastered the turning technique described in this manual on level ground.
Avoid crossing the side of a steep hill if possible.
19. Always use proper procedures if you stall or roll backwards when climbing a hill. To avoid stalling, use the proper
gear and maintain a steady speed when climbing a hill. If you stall or roll backwards, follow the special procedure
for braking described in this manual.
20. Always check for obstacles before operating in a new area. Never attempt to operate over large obstacles, follow
proper procedures when operating over obstacles as described in this manual.
21. Always be careful when skidding or sliding. Learn to safely control skidding or sliding by practicing at low speeds
and on level, smooth terrain. On extremely slippery surfaces, such as ice, go slowly and be very cautious in
order to reduce the chance of skidding out of control.

22. Never operate a quad in fast flowing water or in water deeper than that specified in this manual. Remember that
