Rules for Safe Operation

The driver should have a good knowledge of the operation system of the vehicle 
and its features, and follow the rules for safe operation as stated below:

•  WARNING:

 Drive the vehicle off road unless it is allowed.

• 

The vehicle cannot be over-loaded, otherwise the motor will be damaged, 
the vehicle will lose control and its life will be shortened.

• 

Unqualified persons are prohibited to drive the vehicle.

• 

Make sure this vehicle run in its rated climbing ability.

• 

Don’t overtake other vehicles at crossroad, in blind area or in other dan-
gerous zone.

4: Maintenance

Battery Maintenance

1.  The exterior of the battery, the connection wires and bolts should always 

be kept clean and dry. If there is any electrolyte, it should be wiped off with 
clean cotton cloth, then it should be rinsed by clean water and made dry. 

WARNING:

 During this process, water is prohibited to enter the battery, 

otherwise, the battery will be damaged.

2.  The battery must be kept in good connection. The tightening nuts for the 

wiring connection should be checked frequently to see if any nuts have 
become loose; loose nuts will result in sparks or burnt terminals.

3.  Never connect the positive pole to the negative pole directly. Otherwise, it 

will result in short circuit, and damage the battery.

4.  After discharging (despite of the time it has run and the mileage it has run), 

the battery must be recharged on the same day. Never postpone recharg-
ing more than 24 hours, otherwise the life of the battery will be impacted.

5.  During the use of the battery, the liquid density will increase and the liq-

uid volume decreases due to the evaporation and electrolysis of water in 
the electrolyte (especially in summer). Therefore, the battery should be 
checked periodically and the electrolyte should be added. At the end of 
recharging, adjust the density of electrolyte to a density of 1.280 ± 0.005 
(25 

°

C) by distilled water or dilute sulphuric acid with a density of 1.400 

special for lead-acid battery; in this case, the added liquid cannot exceed
