Chapter IV Operation Methods and Precautions
I. Precautions for Safe Driving
1. Please follow the traffic rules and ensure safe driving. The speed is recommended to be controlled
within the safe range (note that the safe speed shall be controlled within 20Km/h).
2. Before driving, be familiar with the content of the Specification, and then find an empty field for
exercise. Please be sure to fully learn the driving essential and be familiar with the structure and
performance of the electric bike, this is the foundation of safe driving.
3. Don’t lend the electric bike to the person unfamiliar with it and the person can’t drive for use.
Single hand driving or handlebar release or drunk driving is verydangerous.
4. Please pay special attention to safety in case of driving in rainy and snowy days: Rainy and snowy
days will bring danger due to the damp ground! Therefore, it is necessary to avoid high speed driving
and be cautious during turning. Please remember to brake the electric bike in advance in rainy and
snowy days to prevent accidents!
5. Correct use of helmet: Put a helmet on the head and fasten straps during driving.
6. Correct dressing: Don’t wear tights, and ensure that the whole body can move freely. Ensure that
clothes are with closed cuffs and shoes are with low heels. Attention: In order to facilitate maintenance,
repair and service, our automobiles will have frame number and motor number to help the distribution
unit provide better service. The frame number is marked on the base plate of the automobile and the
motor number is marked on the motor shell cover.

7. The cargo can’t be too heavy: The maximum carrying capacity of the electric bike is 100Kg. The
handlebar will have different control feelings during load and noload, and too high load will make the
handlebar easy to vibrate and become dangerous. The stable load of the electric bike is 1 person, and it
will be very dangerous if its front pedal is used to carry cargo and person.
II. Correct Operation Method
1. Driving method
①You can have a free driving if keeping a natural posture.
②Driving with sitting posture: Please sit in the middle of the seat cushion to avoid dangers due to the
front wheel load reduction and, handlebar vibration.
③Driving with standing posture: It is necessary to slowly turn the rolling handle during acceleration
to avoid dangers due to the driver’s gravity center instability owing to suddenacceleration.
④Please drive the electric bike slowly on the damaged road or the road paved with crushed stones.
⑤The pavement will be wet and easy to slide in rainy and snowy weathers, please focus on driving
slowly. When the battery box below the pedal is submerged in accumulated water on the pavement,
please don’t ride the electric bike to avoid burning electric appliances due to short circuit. In such case,
the brake performance will be reduced and the accident will easy occur.
2. Parking method
①When parking, please pay attention to vehicles and pedestrians around and slowly park the electric
bike at the right side of the flat pavement, which can’t be parked on the ramp.

8
②After the electric bike is stably parked, turn the power lock rightwards and remove it, and then will
lock the electric bike with locks.
3. Operation method of the electric quantity indication: Switch on the lock and the voltage indicator
lamp will be on. In case of full charging, the green, blue and yellow lamps will be on. If the green
lamp is off, it means that the electric quantity is only 60% of the rated capacity; if the blue lamp is off,
it means that the electric quantity is only 40% of the rated capacity; if the yellow lamp is off, it means
that the battery runs out. Therefore, when you find out that the blue lamp is off, you shall immediately
charge the battery.
4. Operation method of the power lock: Rotate the power lock key clockwise by one gear, it can be
switched on and the motor can be started. During driving, the key can’t be removed and the power
supply can’t be turned off. In addition, it is also not allowed to rotate the power lock counterclockwise
to switch it off or turn off the power motor to stop rotation. After parking, the power lock shall be
rotated counterclockwise to turn off the power supply and remove the key.
5. Rolling handle (speed regulation handle):
The electric bike will be accelerated if the handle is rotated towards the driver’s direction; otherwise,
the electric bike will be decelerated. After reset, power supply to the motor will be stopped.
6. Operation method and precautions for the disc brake
(1) Operation method of the disc brake
①Brake clearance adjustment: Rotate the adjusting screw by 2mm internal hexagonal wrench
(between the brake handle and the handlebar tube) and adjust the gap between the brake pad and the
brake disc, until you have a comfortable hand feeling.

9
②After the brake pad is used for every six months, or its wear is larger than 1mm or the brake pad
adjusting screw on the brake handle can’t be adjusted, it shall be replaced. When replacing the brake
pad, press in one brake pad with a clean slotted screwdriver to empty the space to take another piece.
After replacement of the new brake pad, the brake pad adjusting screw on the brake handle shall be
returned to the proper position (the position where you have a comfortable hand feeling).
③Running-in period: The running-in of the disc brake surface needs a certain time; after complete
running-in, the brake force will be increased obviously. In the first week, the new brake is in the
running-in period, it is not allowed to forcibly apply the brake; otherwise, the brake pad and the brake
will be irreversibly damaged. The correct operation method is to slightly engage the brake for normal
driving and keep a proper friction between the brake pad and the disc brake disc.
④Oil change: The disc brake is applied with mineral oil. When feeling the brake handle fatigue, oil
shall be changed (usually 2~3 years) by means of suction with the injector suction pipe.
(2) Precautions
①Don’t apply lubricating oil to the disc brake disc, brake pad and places near calipers. Do not touch
the disc brake disc and brake pad surface directly by hand; otherwise, the brake performance will be
significantly reduced.
②The new brake shall not be sprayed with water to avoid polluting the brake pad by a small amount
of lubricating oil in the assembly gap.
③The oil pressure disc brake has strong brake force, so you need more exercises in a safe place, so
as to adapt to its difference with common brake. Avoid forcibly applying the brake, which will cause
injury due to uncontrolled wheel owing to locking.
