Notice:
Dismantling and slinging the component shall not be performed without the
approval of our company. Under special circumstances, the appointed sling
position should be used. The balance weight, fork and mast of the forklift
truck all have their appointed sling position.The above weights are for
reference only and may be adjusted due to different counterweights or
technical optimization.
2.2 Parking of forklifts
（1）The mast is lowered to the lowest position.
（ 2 ） Turn left the key switch and press the emergency stop switch, place all control
levers in the empty position, and unplug the power plug.
（3）Tighten the handbrake lever.
（4）Chock the front and rear tires.
（ 5 ） When the forklift is out of service for a long time, the wheels should be overhead.
Before long-term storage, confirm that the power of the battery system is not less than 50% and
not more than 80%, and charge and maintain it every two months. After storage for more than
two months, please confirm whether the power battery system has a fault alarm before reuse).
（ 6 ） Forklifts shall be stored in a dry and ventilated environment away from heat sources as
far as possible after long-term shutdown.
2.3 Preparation before use
（ 1）Check whether all instruments are normal.
（2）Check tire wear.
（3）Check all handles and pedals.
（ 4 ） (Before using the vehicle for the first time, it needs to be charged to 100% before
use. After the vehicle is powered on, confirm that there is no battery system alarm message on
the instrument panel. Please check the remaining power before use. It is recommended that the
SOC be used between 50% and 100%. If the SOC is less than 15%, it is not recommended to
continue to use. Please charge as soon as possible.).
(5)Check whether the battery and vehicle power line connectors and signal line connectors
are reliable.
7

（6）Check the hydraulic oil and brake fluid for leakage.
（7）Check the tightness of the main fasteners.
（8）Check whether the lighting and signal are normal.
（9）Release the parking brake.
（ 10 ） Carry out the trial operation of mast lifting, forward and backward tilting, forklift
steering and braking.
（11）The contamination degree of hydraulic oil is not greater than Grade 12.
2.4 Precautions for safe operation
（ 1 ） Forklift belongs to special equipment. Only drivers who have passed the training
and examination and hold the driving license can drive; The maintenance of the forklift should
also be carried out by trained and qualified personnel to ensure the normal use of the forklift.
（2）Wear the safety guards, such as clothing, shoes, helmet and gloves while
operating the truck.
（ 3 ） When the center of gravity of the goods is 600mm from the front wall of the vertical
section of the fork, the maximum load is the rated lifting weight, and the load should not
exceed the specified value during handling. If the center of gravity of the goods is more than
600mm from the front wall of the vertical section of the fork, the lifting capacity shall be
reduced according to the value specified in the load curve, and overloading is strictly
prohibited.
（ 4）Operate your forklift truck on hard ground. Operate on other ground, the lift
capacity and travel speed must be decreased. Wipe off the oil and grease from the floor.
（ 5 ） Daily maintenance should be done before or after using the truck. Anytime you find
that the truck is not functioning normally, operation of the truck should be halted and checked
or repaired at once.
（6）When operating one lever, pay attention not to shift another lever. Don’t operate
the lever at any position out of the driver’s seat.
（7）Don’t handle unfixed or loose goods. Be careful to handle bulky goods. To
prevent the collapse of stacked goods, tighten them. Forbid loading loose or little
volume goods without pallets.
（ 8 ） Forklifts with accessories specially ordered by users can make their use more
extensive. However, the forklift with attachments will reduce the payload and stability of the
forklift. Do not use the accessories and special devices for other purposes. Please read the
8

additional instructions we provide for you and use them strictly according to the requirements.
Users are not allowed to modify without permission.
（ 9 ） Do not use a fork to pull the embedded object (if necessary, the pulling force shall
be calculated first).
（ 10 ） When loading goods, the distance between forks shall be adjusted according to the
size of the goods, and the weight of the goods shall be equally shared by the two forks, so as to
prevent the goods from slipping to one side during eccentric loading or driving; It is prohibited
to pick up goods with a single fork.
（ 11 ） When carrying large volume goods, the goods block the driver's sight, and the
forklift should be driven in reverse.
（ 12 ） When loading goods, put the fork to the bottom. After the fork is inserted into the
cargo pile, the front wall of the vertical section of the fork should be in contact with the goods,
and then the gantry should be tilted back to the limit position, and the fork should be lifted 200
mm - 300 mm from the ground before driving
（ 13 ） When lifting or lowering goods, no one is allowed under the lifting frame; It is
forbidden to lift people with a fork.
（14）When loading and unloading goods, keep the mast vertical and the truck is in
braking state.
（15）Because the forklift truck turns by the rear wheels, the end counterweight may
swing widely when turning. Use care in narrow aisles and other workplaces.
（ 16 ） During operation, pay attention to the performance and condition of the system of
machinery, hydraulic, electric and speed-adjuster etc.
（ 17 ） Turn on the power, step on the brake, press the one-button start switch, select the
position of the direction switch, turn the steering wheel to see if the vehicle turns normally, and
slowly step on the accelerator pedal to maintain the proper starting acceleration.
（ 18 ） Pay attention to observe the SOC. When the forklift is working, if the SOC power
is lower than 15%, it is recommended to stop the operation as soon as possible, charge the
lithium battery or replace the lithium battery with sufficient power. If the SOC power is lower
than 10%, the forklift will be forced to operate with reduced power for the protection of the
battery. At this time, it is necessary to go to the charger immediately for charging.
（ 19) The speed of cargo lifting or lowering can be controlled by the number of
movements of the operating handle of the multi way directional valve. The initial speed of
9

cargo lifting or lowering should not be too fast.
（ 20 ） Before tilting the mast forward and backward, the forklift shall be braked, and
shall tilt slowly when tilting forward to prevent the goods from slipping out suddenly.
（ 21 ） Tilt the mast of the high lift forklift truck as backward as possible when operating
the truck. Use minimum forward and backward tilt when loading and unloading. It is dangerous
to travel or turn when lifting the goods at high levels.
（22） It is noted that the goods will fall down when the forks of the truck with lifting
height more than 3m lift, take the protection measures if necessary.
（ 23 ） The overhead guard is the main part which is strong enough to meet safety
standards, and protect the operator from falling materials. It’s very dangerous to dismantle or
rebuild the overhead guard, because these conditions could lead to an accident.
（24） The shelf is a safety part. When the goods are stacked high on the fork and the
gantry is tilted backward, the goods shall be prevented from sliding backward to avoid personal
injury to the driver.
（25） The height of loading and unloading shall be limited to the height of the shelf. If
the height of the goods exceeds the shelf, it is easy to cause the goods to slide to the operator,
which will lead to serious accidents.
（ 26 ） During outdoor operation, the wind has a great impact on the stability of the
forklift, so please pay special attention.
（27）When driving on the wharf or temporary planking, be careful and drive slowly.
（ 28 ） When carrying goods, do not tilt the mast forward, do not load or unload, and do
not brake to prevent the goods from slipping out.
（ 29 ） Forklifts should drive into the cargo pile at a low speed, and pay attention to
whether there are protruding hard objects near the cargo to avoid puncturing the tires.
（ 30 ） When driving, pay attention to pedestrians, obstacles and potholes, and pay
attention to the clearance above the forklift.
（ 31 ） When the forklift is running, the handle, foot and other parts of the body are not
allowed to extend out of the cab, and the vehicle is not allowed to carry people.
（ 32 ） Drive carefully on the ramp, and do not turn, drive laterally or diagonally,
otherwise the forklift may roll over; When carrying goods on a large ramp, drive forward when
going uphill and backward when going downhill; Please use foot brake when going downhill
and drive carefully; When driving on the ramp, it is prohibited to slide in neutral gear and use
the emergency stop button carefully.
10

（ 33 ） Start, turn, drive, brake and stop carefully, especially when turning on wet or
smooth roads.
（ 34 ） It is forbidden to suddenly start, accelerate, stop and turn the forklift. Improper
operation may cause the forklift to roll over. If this happens, the driver should keep calm and
avoid jumping. He should hold the steering wheel with both hands and lean to the opposite
direction of the forklift.
（35）Forklifts with attachments shall be operated as loaded forklifts when empty.
（ 36 ） During the use of the chain, it should be checked regularly to ensure that there are
good lubrication conditions between the chain links, and the tightness of the left and right
chains is consistent; If the chain is worn during use, and the change value of the chain pitch
exceeds 2% of the standard value, the chain must be replaced to ensure safe loading.
（ 37 ） Before the forklift is safely decelerated and stopped, the reverse gear cannot be
engaged to ensure the driver's safety.
（38）When the forklift is running with load, emergency braking shall be avoided.
（ 39 ） When leaving the vehicle, lower the fork to the ground, place the shift handle in
neutral, and disconnect the power supply. When parking on the ramp, pull the parking brake or
step down the parking brake. If the parking time is long, chock the wheels.
（ 40 ） When the mast is tilted forward or backward to the limit position or the fork is
lifted to the maximum height, the handle must quickly return to the middle position.
（ 41 ） The pressure of the multi way valve and safety valve of the forklift has been
adjusted before leaving the factory. Users should not adjust them randomly during use to avoid
damage to the entire hydraulic system and hydraulic components due to excessive pressure
adjustment.
（ 42 ） During the operation of the forklift, additional noise values may be added due to
different operations and the impact of the external environment, which may lead to higher or
lower noise values.
（ 43 ） The driver will feel the vibration of the forklift when operating and driving. The
total vibration value of the double arms transmitted by the forklift to the operator shall not
exceed 1.3m/s2, but the vibration frequency characteristics of the human body depend on the
working conditions (such as road conditions, operation methods, etc.), so the actual vibration
frequency characteristics are determined by the site conditions when necessary.
（ 44 ） In order to handle super wide goods, users can choose "lengthened fork", but it is
worth noting that the bearing capacity of the lengthened fork should work strictly according to
11

the requirements of the load curve. Within the specified load center, its bearing capacity is the
same as that of the standard fork. When the load center moves forward, the load must be
lowered; It is strictly forbidden to lift or hit the goods with the fork tip. Pay special attention to
safety when driving or turning.
（ 45 ） Be familiar with and pay attention to the functions of various signs on the forklift,
and timely subsidize if lost.
（ 46 ） Forklifts are generally used in an environment below 1000m above sea level, with
a temperature of 5℉-104℉ ( - 15 ℃ - 40 ℃) and a relative humidity of 95%; Use with
caution in other harsh environments.
（ 47 ） In order to prevent fire, accident or other unpredictable events, fire extinguishers
shall be set in advance and operated according to the use requirements of fire extinguishers.
（ 48 ） Without the written approval of our company, it is not allowed to modify the
forklift or add any working device, otherwise the rated load or safe operation may be affected.
（49）Pay special attention to safety during high maintenance.
2.5 Maintenance of lithium battery forklift
In the process of using the forklift, careful operation, reasonable use, regular inspection
and maintenance must be carried out to keep the forklift in good working condition for a long
time.
2.5.1 New forklift maintenance
The performance and service life of the forklift are closely related to the maintenance of
the new car in the running period. During the running in period, special attention shall be paid
to:
The gear oil in the differential or reducer shall be replaced after the first 1000 hours of
operation of the new forklift, and all fasteners shall be re-tightened after replacement.
2.5.2 Starting essentials
（ 1 ） Oil volume of hydraulic oil: the oil level shall be in the middle of the oil level gauge
scale.
（ 2 ）Check the pipes, joints, pumps and valves for leaks and damage.
（ 3 ） Check the service brake: the idle stroke of the brake pedal shall be 5mm. When the

mode, and the whole vehicle has three working modes: E, S and H. E is the energy-saving
mode, in which the battery life is the longest; S is the standard mode, with moderate power
consumption and endurance; H High performance mode, in which the power is strong.
2.6.3 Maintenance of control system
During the use of lithium battery forklift, the control system shall be regularly maintained
as follows:;
（ 1 ） Check the contact wear of the contactor and whether the contactor moves freely.
The contacts shall be checked every three months.
（ 2 ） Check the foot pedal or handle the microswitch. Use a multimeter to measure the
voltage drop between contacts and ensure that there is no resistance between contacts. The
sound of microswitch opening and closing should be clear and crisp. The microswitch shall be
inspected every three months.
（ 3 ） Check the connecting wires of the main circuit to ensure that the cables of the
lithium battery, controller and motor are well insulated and firmly connected.
17

Cables shall be checked every three months.
（ 4 ） Check the spring of the pedal or handle. Ensure that the spring can deform normally
and return to its original position. Check every three months.
（ 5 ） Check the movement of the contactor. The contact of the contactor should move
freely to ensure that the contact is not bonded. Check every three months.
Note:
Please do not open the controller by yourself, otherwise the controller will be damaged
and the warranty will be invalid. Keep the controller clean and dry, and regularly check and
eliminate the diagnostic history files. It is strictly forbidden to start the electric control for
vehicles with incorrect installation.
Regular maintenance should be carried out by trained professionals. If damaged parts need to
be replaced, please use the original accessories provided by our company to ensure quality.
If any condition that may cause damage or endanger the safety is found during the inspection,
the dealer shall be informed immediately, and the dealer shall decide the operation safety of the
vehicle.
2.6.4 Special reminder
（1）As a special vehicle, the lithium battery forklift needs to be operated and maintained
by qualified professionals, and attention should be paid to its use characteristics and working
environment in order to avoid unnecessary failures of the electrical system (including
instruments).
（ 2 ） As the vehicle power source, lithium batteries are different from traditional energy
sources. Its actual capacity is directly related to the working condition and its own aging
condition, and is somewhat different from the rated capacity. According to the general use of
lithium batteries, when the power drops to 20% (1 grid), the lithium battery must be charged,
which will help to extend the life of the lithium battery.
（ 3 ） Using a PC or handheld device to connect with the controller, users can access the
powerful software setting interface within certain permission, so as to more intuitively detect
and understand the working conditions of the whole vehicle, such as the working current and
speed of (AC) drive motors, and improve a series of system parameters such as the working
current, speed, service time, fault list, etc. of the motor.
