and maintenance of forklift. It is used for any other purpose, which are not in conformity with
the provisions operation behavior, can lead to injuries and fork lift truck or other property
damage. The most important thing is to prevent the load is overweight or swaying caused by
overload. Must abide by the the biggest load limit in equipment nameplate or Load graphic
Drawing can’t use the fork lift truck in a fire and explosion hazard area, cannot use in easy to
cause corrosion rust and dust area.
Obligations and responsibilities of equipment user：“equipment user”Refers to
natural person or legal person who is direct use or appointed entrust others use the forklift in
this operation manual. In the rental, lease and other special circumstances, “equipment user”
represent the contract terms between equipment ower and user. Equipment user must ensure
that the forklift only is used to specified use, and promptly eliminate all may endanger the risk
of life and health to user himself or a third party. In addition, the equipment use party must
strictly abide by the accident prevention regulations, other safety technical regulations, and
equipment operation, maintenance and maintenance philosophy. Equipment user must ensure
that all operations staff carefully read and fully understand the content of the operating
instructions.
If you don't follow the operating instructions, the company's quality assurance to be
automatic failure. If the customer and/or the third party to make the equipment non-standard
without any allowable from out customer service department.，we will not undertake any any

Ⅱ．Forklift introduction
1. Range of application
20EDPR series electric pallet truck is powered by storage battery, and driven by motor. This kind
of truck travels by means of gear transmission. The fork is lifted by means of DC motor and
hydraulic actuation, which motivate hydraulic cylinder up and down to lift fork and goods
together.
Rated load datails on the forklift nameplate.
2. Service environment
a. Height above sea level shall not be over 1000m；
b. Ambient temperature shall not be higher than +40℃and no lower than -25℃；
c. When the ambient temperature reaches +40℃, the relative humidity should not exceed
50%; at a lower temperature, higher relative humidity is allowed；
d. Hard and flat ground.
e. It is prohibited to use the truck in a flammable, explosive or corrosive environment with
acid and alkali.
f. Because the vehicle itself without lighting equipment,so the truck should use in light
brightly.

（i）Instrument:
This instrument is a combination of battery
capacity indicator and LCD hour meter, with the
battery indicator of ten segments of colorful LED
display (5 red segments, 3 yellow segments and 2
red LED).When battery discharges by 70% capacity,
one red flicker lamp shows “energy storage” alarm.
When the battery discharges by 80%, two red
flicker lamps show “energy exhaust”. After the
external power supply is cut off, the internal battery
can generally keep storage memory of 10 years.
The life service time for monitoring of this
instrument is 99999.9 hours recorded on LCD
displays. Hour meter resets automatically and
continue to time and display. Only if it is
connected to battery, LCD hour meter will start
working. This instrument possesses high
reliability under extremely bad environment.
（2）Steering system:
The steering system mainly composes of operation handle, steering device shaft, and floating
No.

support bearings. The system is used to control travel direction of the truck.
（3）Braking:
The brake of this truck is electromagnetic. When the accelerator pedal is released, the
electromagnetic arrester will be out of power and braked. When the accelerator is released
during the traveling of the truck, the controller will carry out electric brake at first. This kind of
brake is regenerative braking and can turn the dynamic energy to electric energy which can be
recharged to battery. When the truck is stopped, the electromagnetic arrester will be out of
power and braked again. This electromagnetic brake type not only prolongs the service time of
storage battery and arrester but also reduces the wearing of the brake plate.
（4）Operation control
1．Lift button of support leg 2.Accelerator knob 3.Emergency reverse button 4.Horn
5.Slow button 6.Lift button of fork
①Lifting and lowering operation: Press the lowering button of the forks, the forks will lower.
While the lifting button is pressed, the fork will lift. Press the lowering button of the support leg,
it lowers, Press the lifting button of the support leg, it lifts. Lift the forks when stacking and lift
the support leg when carring.
②Accelerator knob: It is used to control the travel direction and speed of the electric truck.
Before operation of the truck, firstly turn the operation handle to area B shown as above. When
the handle is placed in area A or C, the truck will be powered-off and braked. At this time, the
truck can not drive. When the operation handle is placed in area B and the acceleration knob is
turned in one direction, the truck will travel in that direction. Meanwhile the truck will be
accelerated with the increasing of rotation amplitude of the knob. When the accelerator knob is
turned in another direction, the truck will travel in another direction. Likewise, the truck will
speed up with the increasing of rotation amplitude of the knob.
③Horn button：Horn of the truck will be turned on if you press the button.
Emergency reverse button: when the operation handle is placed in area B and the emergency
reverse button is pressed, the truck will travel in an opposite direction away from the operator
immediately. This is a safety switch which can avoid the operator from being squeezed under

unexpected condition.
④Slow button: When this button is pressed, the truck will travel at an extremely slow speed.
This button is applicable for operation on especially narrow field or on the condition that the
truck needs to be accurately located.
（5）Electric lock：It is used to control switching-on and switching-off of main power supply of
the truck. Key of the electric lock shall be kept by the truck driver or personnel who have been
specially assigned. Be sure to cut off the main power supply when you leave the truck, and take
the key of electric lock, for fear occurrence of accident due to operation carried out by others.
（6）Battery main switch ：to control the emergency power off,put down the mushroom head
is power dump.,pull out the mushroom head is power-on，when your truck is out of control,
please press the mushroom head to cut off power to avoid the accident.
（7）Pedal and guardrail: The operation mode of this truck is stand driving. Under normal
conditions, the standing pedal and guardrail should be open before driving the truck. During
operation of the truck, the driver should stand on the pedal. When the working area is relatively
narrow, the standing pedal and guardrail can be put away. Then, the maximum traveling speed
should not be over 4km/h.
