Before Initial Use
Read, understand and follow the safety label on the instrument panel. Be sure you understand how
to operate the vehicle, its equipment and how to use it safely. Maintaining good performance
depends to a large extent on the operator.
New Vehicle Inspection
Before a new vehicle is put into operation, the items shown below must be performed.
1| Check status of each spare part, especially the screw and nut on the steering wheel and brake.
2| Check for any leakage problems with the steering system , turning system and transaxle.
3| Check the electrolyte level of the battery.
4| Check if tire inflation is correct. Low pressure will lead to difficulty turning and bumpy riding.
5| Check if there is any damage between the wiring and other locations where pieces rub against
each other.
Maintenance
Turn off the electricity, take out the key and engage the parking brake.
When working underneath vehicles, please use jack and triangle wood to fix the front and rear
wheels, in order to avoid accidents.
Keep the maintenance area clean and safe.
Please perform vehicle maintenance according to safety guidance.
No smoking in the working sites. The facility of extinguishing fire should exist in the working sites.
Don’t use fire to check the height and leakage of the electrolytes in the reserve battery. Don’t use
the flammable liquids to wash off parts.

13
Maintain the ventilation of working sites.
Check and maintain under safe working conditions. Check and maintain the braking, steering, speed
direction control system, emergency facilities, head/rear lights, controller, and safety equipment.
Check the battery cover as per the right methods.
Battery Maintenance
The batteries for this vehicle have high current, high capacity, and a long lifetime. To keep the
vehicle in good performance, it is very important to maintain it in the correct procedure.
The connectors on the batteries are the output connectors. Keep the area clean and dry, with no
foreign matter or dust on it, or the leakage or short-circuit. This will shorten the battery life or
possibly burn it out.
WARNING: Don’t let tap water enter the battery.
Check the height of the electrolyte periodically. Check it once per week in summer and once every
two weeks the rest of the year. Standard height level is 10-15mm (½“) higher than the battery
plate. If is too low, please add the recommended distilled water or liquid.
Keep the wiring well-connected. After using the vehicle initially for 2-3 days, the completed
inspection for all connectors should be carried out. Inspect the vehicle once a week following. Any
loose or rusty connectors should be fixed. Loose or rusty connectors can cause high temperature,
damage, or possible sparking.
NOTE:Don’t over-tighten terminals.
Charge the battery immediately after discharge, or it will affect the battery life.
Keep the filling-water container clean, so no impurities will be put into the battery.
When the environment temperature is under -40° F, the density of the electrolyte after charging is
1.28 - 1.29 g/cm3. If it is more than 1.30 g/cm3, the battery can be damaged badly. Add water
immediately to keep the electrolyte value to normal. If the battery discharges by 80% (the
electrolyte is between the range 1.13 - 1.15 g/cm3), charge it immediately. At this range the vehicle
can only last 2 - 3 mi. Don’t discharge any longer, or it will damage the battery.
Charge the battery fully before storage. Charge it at least once a month for 24 hours.

14
Battery Replacement
Replace the batteries immediately when it approaching to the battery life, as the capacity will
decrease quite fast and can’t meet the range requirement. The detailed replacement way can be
consulted with the supplier.
Remove battery hold downs and cables. Lift out batteries with a commercially available lifting
device.
If the batteries have been cleaned and any acid in the battery rack area neutralized as
recommended, no corrosion to the battery racks or surrounding area should be present. Any
corrosion found should be immediately removed with a putty knife and a wire brush. The area
should be washed with a solution of sodium bicarbonate (baking soda) and water and thoroughly
dried before priming and painting with a corrosion resistant paint.
The batteries should be placed into the battery racks and the battery hold downs tightened to 45 -
55 in. lbs. (5 - 6 Nm) torque, to prevent movement but not tight enough to cause distortion of the
battery cases.
Inspect all wires and terminals. Clean any corrosion from the battery terminals or the wire
terminals with a solution of sodium bicarbonate (baking soda) and brush clean.
WARNING: To prevent battery explosion that could result in severe personal injury or
death, extreme care must be used with aerosol containers of battery terminal protectant.
Insulate the metal container to prevent the metal can from contacting battery terminals
which could result in an explosion.
Use care to connect the battery wires as shown. Tighten the battery post hardware to 50 70 in. lbs.
(6 -8 Nm) torque. Protect the battery terminals and battery wire terminals with a commercially
available protective coating.
Battery Connections

15
Charging the Battery group
In order to guarantee battery life, please use the recommended charger to charge the cart.
Keep the key switch on OFF position during charging.
Keep the battery in cool, dry location. Don’t use the charger in rain or hot weather.
Don’t overcharge the battery, or it the electrolyte will expel from the battery which can damage the
vehicle and the storage performance of the battery.
Ensure that the AC power is consistent with the input power. After connected, the green light
indicates the vehicle is charging. The red light indicates that charging is complete. At this time the
power will be cut off automatically to avoid overcharging.
Charging should be monitored.
NOTE: Don’t remove the plug connected to the vehicle prior to disconnecting from the AC
power source.
Brake System Maintenance
Adjust the gap between the brake drum and brake shoes.
Dial up the adjusting ratchet wheel of the brake drum until the
wheel cannot turn freely, then dial down the ratchet wheel 7 - 8
teeth.
Steering System Maintenance
Check if there is any damage to the dust cover of the tie-rod. A broken dust cover will let water in
and damage the tie-rod, and the steering system will not be flexible. Replace a new one immediately
once a worn one is found. Make sure the front wheel toe-in is between 3 - 5 mm (1/8 – 3/16”). If it
exceeds this value, adjust the tie-rod screw stem.

16
Motor Maintenance
Keep the motor surface clean at all times. Clean the surface with a dry cloth. Avoid any water
entering into the motor.
Lubrication maintenance
Check the brake once a month. Fill it full if the oil is low.
The gear oil should be changed once a year. User can choose gear oil according to the climate.
•Summer: GL-4 90
•Winter: GL-80W/90
Replace the grease for the rear axle once a year, using recommended oil type GL-5 90 and GL-5
80W/90. Fill the level to 1.2 liters (40 oz).
When changing, first twist down the oil plug to discharge the gear oil. Clean the oil plug and replace
it, then inject the new gear oil.
