3. Before riding
4. Safe riding
This manual describes the correct usage of the SYMBA including: inspection and safe riding techniques.
For a safe and enjoyable ride, please read this manual carefully.
For your benefit, please ask your SYM dealer for the operating manual and carefully read the
following:
Correct use of the SYMBA.
Pre-delivery inspection and maintenance.
Thank you very much for your patronage
In order to maximize your SYMBA’s performance, periodical inspection and maintenance should be
completely carried out.
We recommend that after riding your new SYMBA for the first 200 miles, you should take your SYMBA
to the original dealer for an initial inspection, and to have your SYMBA inspected periodically every 620
miles thereafter.
In case the SYMBA’s specifications and construction are modified and different from the photos and
diagrams on the owner’s manual / catalogues, the specifications and construction of the actual SYMBA
shall prevail.
4. SAFE RIDING
It is very important to be relaxed and clothed properly when driving, observe traffic regulations, do not rush,
always drive carefully and relaxed. Relax and have FUN!!
Usually, most people would ride their newly bought SYMBA very carefully, but after they became familiar
with their SYMBA, they tended to become reckless which may result in an accident.
To remind you:
Please wear a safety helmet, and properly tighten the chin strap when riding your SYMBA.
Clothes with open or loose cuffs may be blown by the wind and cause the cuffs to get caught on
the handlebar and thus affects riding safety.
Hold the handlebar with both hands when riding. Never ride with only one hand.
Observe the speed limit.
Wear suitable low-heel shoes.
Perform periodical maintenance and inspection in accordance with the schedule. (Page 23)
WARNING!!
Only one operator is allowed, no passenger.
After running, the exhaust pipe is very hot, be careful not to get burned when conducting an
inspection or maintenance.
After running, the exhaust pipe is very hot; select a suitable location to park your scooter to avoid
others getting burned by the exhaust pipe.
WARNING:
Modifying the scooter will affect its structure or performance, and cause poor engine operation or
exhaust noise, which will result in shortening the scooter’s service life.
Besides, modification is illegal and does not conform to the original design and specifications.
A modified scooter will not be covered by the warranty; therefore, do not modify your scooter at will.

5. Driving
6. Use genuine spare parts
Keep the related parts of your body (arms, palms, lumbar, and toes) relaxed and ride with the most
comfortable posture in order to be able to react quickly whenever it is necessary.
Rider’s posture will greatly affect riding safety. Always keep your body’s weight in the center of the
saddle, if your body’s weight is on the rear part of saddle, the front wheel load will be reduced, and this
will cause the handlebar to shake.
It will be much easier to make a turn if rider leans his body inward when turning.
The SYMBA is hard to control on bumpy, unlevel, or unpaved roads. Try to know the road conditions in
advance. Slow down and use your shoulder’s force to control the handlebar.
Suggestion: Do not load objects on the front pedals unnecessarily to avoid affecting the ride safety and
the operation of the handlebars.
WARNING:
The rider’s control on the handlebar is slightly different with a load or without a load.
Overload may cause the handlebar to swing and affects riding safety.
Therefore, do not overload your scooter.
WARNING:
Do not place flammable materials such as rags between the body side cover and engine to avoid
components damaged by fire.
Do not load objects on areas not specified for loading to avoid damage.
SUGGESTION
To maximize the scooter’s performance and prolong its service life:
The first month or first 620 miles is the break- in period for the engine and components.
Avoid rapid acceleration, and keep the speed below 40mph.
6. USE GENUINE SPARE PARTS
In order to maintain the SYMBA’s best performance, each part’s quality, material, and machined precision
must conform to the design requirements. “SYM Genuine Spare Parts” were made from the same high
quality materials used for the original scooter. No parts are sold in the market until they meet the
designed specifications through sophisticated engineering and stringent quality control. Therefore, it is
necessary to purchase “SYM Genuine Spare Parts” from “SYM Authorized Dealers or Franchised
Dealers” when replacing spare parts. If you buy cheap or fake substitute parts from the market, no
guarantee can be provided either for the quality or durability. Also, it may result in unexpected troubles
and lower the SYMBA’s performance.
●Always use SYM Genuine Spare Parts to keep your scooters pure blood and to ensure its long service
life.
