The loading capacity Graph shows a given load center c [Inch] and a car with
horizontal load ,the maximum load capacity Q [LBS] In the corresponding lifting height of
the truck H [Inch]
8.3Lifting up/Lowering down
Pls don’t overload, The related capacity is 1000KG/1600KG/2000KG .Only increase
the load capacity allowed by the load capacity graph
Please lower the fork completely on the leg during driving .Then press lift up

8.4Traveling
Only drive on the slope when the cargo is facing up
Don’t drive on the slope in excess the specified specifications .
Only can driving when the fork falls to the lifting point (<300mm)
⚫Turn the inserted key to the “open”position(Figure 8),Then pull up the
emergency stop switch (Figure 7.4), to start the truck.
⚫Move the handle to the operating area（‘F’figure 13）.Turn the accelerator
button
！

to the forward direction‘Fw”or backward direction‘Bw’(Figure 11)
⚫Control the driving speed by carefully moving the button (fig.7.2)until reach your
desired speed .If you move the accelerator button back to the middle position,
the controller will slow down the truck until it stops. If the truck stops, the
parking brake starts to work.
⚫Drive the car carefully to the destination, Observe the road situation and adjust
the speed with the travel switch button
8.5Steering
The car with EPS steering system, Be careful when operating.
Steering the car by turning the handle to the left or the right
8.6Braking
Braking performance depends on road conditions and the loading conditions of car
The brake function can be activated in the following ways :
⚫By moving the accelerator (figure 7.2) to the “0)position or release the button,
Regenerative braking is activated and the truck brakes until it stops .
⚫By moving the accelerator (figure 7.2) directly from the drive direction to the
opposite direction., the truck regenerates braking until it starts driving in the
opposite direction
⚫The truck brakes if the handle moves up and down to the braking zone（‘B’）.If
release the handle, it will automatically moves to the upper braking zone（‘B’）
and the car brakes until it stops
Emergency reverse button(figure 7.3)prevents the operator from being squeezed.
And if this button is activated ,the car slows down /or begins to travel backwards
（‘Bw’）and then stops. If the handle is in the operating area and the truck is
not moving .consider that this button still works for this situation
8.7Brake structure &Brake Schematic
！

20
Braking principle：as figure12 shows including ：Brake by
magnetic yoke assembly 6、Magnet exciting coil 7、Spring 2、
brake disc 5、Armature 1、Geared sleeve 4、Mounting screw
3 .The brake is mounted on the end cap of the motor ,and the
mounting screw is adjusted to the specified air gap value. The
gear sleeve is fixed on the shaft .The external teeth cooperate
with the internal teeth of the brake disc. And the torque is
transmitted during operation. Then the brake disc can move
axially on the gear sleeve .
When Magnet exciting coil 7 of brake is energized .the coil
produces a magnetic field that caused the armature 1 draw toward the magnetic yoke
assembly 6.Armature 1 detached from the brake disc 5(Release).Then the motor drive
shaft with brake disc 5 start and operate normally. When Magnet exciting coil 7 is de-
energized., The magnetic flux disappears .Armature 1 is released .and spring 2 process
armature 1,then the friction plate on the brake disc is pressed to generate frictional force
for braking purposes
8.8Trouble
If there is any error or the car is not operate,Stop using and press the emergency stop
switch(Figure 1.7).Parking the car in safe area if possible .Turn the key counterclockwise
and remove the key(figure 8).Notify the manager or contact your after-sales service staff
immediately .Use a special towing equipment /lifting equipment to pull the truck out of
the operating area if necessary .
8.9Emergency situations
Keep a safe distance in an emergency situation or the car is turned over. Press the
emergency stop switch(Figure 1.7) and all electrical functions will stop.
