III. Operation Procedures for New Car
1. Notes before using the new car
For a new car, large friction force occurs among running components as car traveling. As running-in of the
components, the friction force will gradually reduce. The following notes are proposed for traveling under 3000km
and with the use of these notes, better operational capacity and economy will be gained after the car running-in.
(1) The traveling speed shall not exceed 40km/h.
(2) It is prohibited to driving the car with over-speed and overload.
(3) The transmission oil must be replaced after traveling 2,000 km.
(4) Emergency braking shall be avoided especially during the first 300Km traveling except for emergency
conditions.
2. Actuation switch: there are three positions for the key in the hole:
Lock (lockin position)
The key can be extracted from or inserted into the lock cylinder, and if the key cannot rotate in the cylinder, please
try to slowly revolve from left to right.
When the car is traveling, the key cannot be rotated to the “LOCK” position, or the steering wheel will be locked
and accidents may be resulted from this condition.
Three rotation positions of the key
ACC (accessory position)
When the ignition switch is at "ACC" position, only the assistant power supply for radio etc will be controlled. At
that time, even the motor is closed; the user can enjoy the radio.
ON (startin position)
When the key is at this position, the turn control, radio and motor are all switched on, and the users can enjoy radio
and open the hazard signal switch.
The features not controlled by the key, such as headlight, horn, interior lights and width indicator can be directly used without key. Inspect whether the

ROMET 4E Electric Vehicle Instruction Manual

voltmeter and electricity meter are ample or not.
The key shall not be left in the car with no one or only kids.
3. Start-up operation of Electric Vehicle
The Electric Vehicles can be divided into two pursuant to high and low speeds: one is Electric
Vehicle with low-gear transmission; the other is Electric Vehicle with high-low gear
transmission (option).
As the key is at the start-up position, open the master switch and inspect the road condition in
front and manual braking condition, the user can drive the car only after confirmation for the
above.
① There are three positions for Electric Vehicles with low-gear transmission: Neutral, drive and reverse positions. The control lever is between the two front seats
and the operation procedures are as follows:
(1) When the lever is vertical at the medium position, (2) The leveler is pushed forward to the drive (3) The lever is pushed backward to “R” position.

it is neutral position. At this time, even slowly
engaging the accelerator, this car cannot travel.
position, and the car will travel after engaging the
accelerator under proper conditions.
And this gear can realize reversing the car (the
reversing red indicator will light up).
Operation procedures of the Electric Vehicle:
For the Electric Vehicles with low-gear transmission, the start-up procedures are as follows: 1. rotate the key to the start-up position; 2.
push the control lever to the forward position; and 3. slowly engage the accelerator pedal. Then you can drive the car.
For the Electric Vehicles with high-low gear transmission, the start-up procedures are as follows: 1. rotate the key to the start-up position;
2. press the forward button of the power switch; 3. push the control lever to the low-gear position; and 4. slowly engage the accelerator
pedal. Then you can drive the car.
① No shifting during engaging the accelerator pedal! Slowly engaging the accelerator pedal during start-up can extend the traveling mileage!
② If the front wheel can not rotate during acceleration, the user shall not drive the car, while the possible reason is that the wheel has been immersed in the
deep sandpit or muddy ground, or it may be blocked by something hard. At this time, if the car is forced to travel, the differential may be damaged. Likewise,
when the car is traveling uphill, the braking shall not only depend on braking pedal to prevent reversing, or the transmission case may be damaged. At that time,
the car shall be stopped on the slope with parking brake!
4. arking brake
For parking braking, lift the manual braking handle (1) with your right hand to brake the car. The user shall first
slightly pull the handle up and use the thumb to press the locking button (2) on the handle top in order to release
the braking handle. ut down the handle (3) and the parking will be released.
If the parking brake is not fully engaged, it is very dangerous to leave the car behind, and your car may
voluntarily move due to environmental factors. If the engine is still running, then the car may suddenly
travel resulting in personal injuries. Thus, you shall ensure your car cannot move and inspect the parking
brake is fully engaged.

Do not shift into high gear or low gear during accelerating. The transmission will be damaged unless you move your foot away from the accelerator pedal before
change gear.
Forwarding and reversing of the car are subject to the switch of “forward” and “reverse”. Move your foot away from the accelerator pedal during switching forward
gear and reverse gear! Otherwise an accident will take place. Be careful!
1. Do not shift into reverse gear as the car is forwarding, the reverse gear is available only when the car is under the condition of shutting down.
2. The car can be forwarding, only when switched on, and the operating arm is shifted into low gear.
3. The ranges of the car can be reduced as a result of using top gear. Suggest using low gear, or the ranges of the car may be shortened.
