Inflating the Tires
NOTE:The 6”rear tires are inflated when shipped, but they invariably lose some pressure
between the point of manufacturing and your purchase. Always inflate the tires to the correct
PSI before first time use.
Please read the specification sheet to get the information of tire pressure.
Using a bicycle-style tire pump to inflate the tire to the PSI indicated on the sidewall of the tire.
Note: The pressurized air supplies found at gasoline stations are designed to inflate
high-volume automobile tires. If you decide to use such an air supply to inflate your tires, first
make sure the pressure gauge is working, then use very
short bursts to inflate to the correct PSI. If you inadvertently over-inflate the tire, release the
excess pressure immediately.
Important information of use guider for tire
Note: Tire is the only contact between the vehicle to the road, the safety of various driving
activity depends on the small area of tire where contact with the road. Therefore, it is very
important to keep the tire in good condition any time and use the correct size and standard tire
to replace the old ones.
Guide:
Tire assembly and disassembly
It is strongly recommended that the tire assembly and disassembly should be done by an
authorized technician with necessary skills.
Tire inflating pressure
It is very important to keep the tire in proper pressure and check the tire pressure before use.
The inflating should be done while the tire is cold.
Tire maintenance
Tire tread depth should be checked regularly.( Shallower tread means less grip of tire). You
must stop to use the vehicle if the tire is pierced, disassemble the tire and check it carefully.
Tire maintenance should be done by an authorized technician. Tire should be replaced
immediately when it is distorted or damaged.
Tire replacement
It is important to use the correct size and standard tire as per our specification (see details in
technical specification sheet)
Don’t use the used tire if you are not sure its previous service condition.
Tire aging
Tire aging is unavoidable even the tire is not ever used or just used a few times. Tire aging is
mainly reflected in the cracked section on side of tire and tire tread, sometimes the tire is
distorted as well. The used and aged tire should be checked and confirmed if it is ok to use
again by an authorized technician

BEFORE RIDING
Charging the Battery
Your electric mini ATV may not have a fully charged battery; therefore it is a good idea to
charge the battery prior to use.
· Initial charge time: 12 hours
· Run time: up to 45minutes
· Average battery life: 120 charge/discharge cycles
· Recharge time: Always remember to turn the power switch off and recharge for at least 10
hours after each use. When vehicle is not in regular use, recharge battery at least once a
month until normal use is resumed. If you have left the power switch on or your product has not
been charged for a long period of time the battery may reach a stage at which it will no longer
hold a charge.
WARNING:
Always disconnect your electric mini ATV from the charger before cleaning with liquid.
The charger has a small window with two LEDs to indicate the charge status. Red LED means
the battery is in charging and Green LED means the battery is full charged. Chargers have
built-in over-charge protection to prevent battery from being over-charged.
Be sure to properly align the groove on the charger input port with the corresponding
socket on the Mini Quad and tighten threads; otherwise, no charging action will occur.
Warning: Failure to recharge the battery at least once a month may result in a battery that
will no longer hold a charge.

How to charge the battery and change the fuse.
The fuse is pre-fitted by the factory into your battery pack. Before you use the vehicle for the
first time you will need to connect the power lead to the battery pack. Once you have
connected, connect your charger to the charge point on the removable battery pack and
Charge the quad for 10 hours before the first use. Ensure the keys are removed from the
vehilce whenever you charge, if you leave the key turned on while charging ,it will never
charge the quad fully. For the first initial charge, leave you vehicle on charge even if the
charger turns to green which will help to boost your batteries and increase overall battery life
and range per charge. After the initial 10 hours,disconnect your charger once the led on the
charger has turned to green. Never leave on charge unsupervised!
1) Connect the power lead to the battery pack.
2) Connect the charger to the charge point.
3) Ensure the ignition key is removed and charge for 10 hours.
Replacing the fuse guidance
1) Remove your battery pack from the vehicle.
2) Using a cross head screwdriver undo the 6 bolts that secure the top of the battery
casing.

- 17 -
3) Once you have removed the 6 screw,please carefully remove the top of the battery
casing (Please be aware there are electrical cables connecting the top section of
the case to the batteries in the lower section)
4) Locate the fuse holder within the battery pack. This is normally glued to the underside
of the battery pack lid.

- 18 -
5) Open the fuse holder and remove the fuse and replace with your spare fuse. Reverse
the procedure to refit the battery pack.
PRE-RIDE CHECKLIST
❑Loose Parts
Check and secure all fasteners before every ride. Make sure steering stem clamp bolts are
locked properly in place. There should not be any unusual rattles or sounds from loose parts or
broken components. If you are not sure, ask an experienced mechanic to check.
❑Brake
Check the brake for proper function. When you squeeze the lever, the brake should provide
positive braking action. When you apply the brake with the speed control on, the brake cut-off
switch will stop the motor.
❑Frame, Fork and Handlebars
Check for cracks or broken connections. Although broken frames are rare, it is possible for an
aggressive driver to bash into a curb or wall and wreck and bend or break a frame. Get in the
habit of inspecting yours regularly.
❑Tire Inflation
Periodically inspect the tires for excess wear, and regularly check the tire pressure and
re-inflate as necessary. If you get a flat tire, the inner tube can be patched or a new tube can
be purchased from Razor or an authorized repair center.
❑Safety Gear
Always wear proper protective equipment such as an approved safety helmet, elbow pads and
kneepads. Always wear shoes (lace-up shoes with rubber soles), never drive barefooted or in
sandals, and keep shoelaces tied and out
of the way of the wheels, motor and drive system
REPAIR AND MAINTENANCE
Turn power switch off before conducting any maintenance procedures.
❑Adjusting the Brake
The mini quad is with 2 front brake and 1 rear brake.
WARNING: The brake is capable of causing the electric mini quad to skid the tire throwing an
unsuspecting rider. Practice in an open area free from obstacles until you are familiar with the
brake function. Avoid skidding to a stop as this can cause you to lose control or damage the
rear tire.

- 19 -
REPAIR AND MAINTENANCE
❑Adjusting the chain
1. loosen the 4pcs nut (B)
2. loosen the screw (A) and press the
plastic buckle to remove the chain
cover.
3. loosen the chain adjuster nut (C),
adjust the chain properly ( refer to the
standard: chain can move freely up
and down about 4mm), then fasten the
nut (C) and (B)

- 20 -
❑Chain and Sprocket
The chain will typically have a “loose spot” and “tight spot” corresponding with a particular
sprocket rotational position. This is normal and common to all chain-driven vehicles due to
run-out tolerances of the freewheel and sprocket. Proper chain alignment must be maintained.
If the chain is noisy or rough running, check the lubrication, tension and alignment of the
sprockets, in that order. The tensioner arms must be aligned and free from binding and the
tensioner spring(s) must be operating correctly.
Warning:
To avoid a pinch or injury, keep fingers away from moving sprockets and chain
❑Battery Care and Disposal
Do not store the battery in temperatures above 75° F or below -10° F.
CONTAINS SEALED LEAD BATTERY. BATTERY MUST BE RECYCLED.

in an environmentally sound manner. Do not dispose of a lead-acid battery in a fire. The
battery may explode or leak. Do not dispose of a lead-acid battery in your regular household
trash. The incineration, land filling
or mixing of sealed lead-acid batteries with household trash is prohibited by law in most areas.
Return exhausted batteries to a federal or state approved lead-acid battery recycler or a local
seller of automotive batteries.
Warning:
