the electrical system, such as open circuit, short circuit, or active button, if you stamp the pedal switch,
speed control device is not in the neutral position, and the truck cannot be operated and a fault code
appears, only when the fault from electrical system is solved, the truck can be operated normally.
d. Steering
The truck equips with an electric steering system. Take care by operating a truck with this kind of system.
Steer the truck by turning the steering wheel clockwise and counterclockwise.
Turn the steering wheel to make the drive wheel move straightly forward, truck will reach full speed. Turn
the steering wheel a certain angle to turn the drive wheel to achieve steering. During steering, when the
turning angle is larger than ±10°, comparing with straight driving, the steering speed is different, the
larger the turning angle, the slower the speed, which ensures the smooth steering and safe operation.
e. Braking
The braking performance depends on the track conditions and the load conditions of the truck.
●When driving the truck, if the right foot releases the accelerator pedal, the truck begins to decelerate.
If you need a shorter braking distance, please directly step on the brake pedal until the truck stops;
●Release the safety pedal switch (6), the braking is activated and the truck will be stopped.
●Press the emergency button (1), the braking function is activated and the truck will be stopped..
Attention: if there is load on the fork, the brake should be activated slowly. Do not use emergency
braking, otherwise the load may drop from the fork.
f. Residual lift diagram
The residual lift diagram indicates the maximum capacity Q [kg] for a given load centre c [mm] and the
corresponding lift height h3[mm] for the truck with horizontal load.
The white mark on the mast indicates the possible lifting limits.
For instance, OPX with a load centre of gravity distance (c) of 600mm and a maximum lift height (h3) of
9500mm, the maximum capacity (Q) is 800 kg.

g. Lifting
DO NOT OVERLOAD THE TRUCK! THE MAXIMUM CAPACITY IS 1500KG
REFERRING TO THE IDENTIFICATION PLATE.
LIFT THE LOAD THAT IS INDICATED AND ALLOWED IN RESIDUAL LIFT DIAGRAM
ONLY, OTHERWISE IT MAY DAMAGE THE TRUCK.
Pull the lifting and lowering control stick (7) backwards to lift the fork until it reaches your
desired lifting height.
When the lifting height of the unladen truck is above 3m or the lifting height of the laden
truck is above 1m, please reduce the speed of the truck. Be careful of operation during
steering, no sharp start, stop or steering.
Be cautious during lifting operation in racks, pay attention to the distance between the
load and the rack.
h. Lowering
If the fork is in the racking, firstly travel out of the racking carefully with or without the pallet.
Push the lifting and lowering control stick (7) forwards for lowering.
Lower the load until the fork is clear of the pallet, then move the truck carefully out of the load.
i. Fork lateral movement (left/right)
Push the control stick (8) forwards, the fork moves to the left.
Pull the control stick (8) backwards, the fork moves to the right.

j. Fork rotation (left/right)
Push the left and right rotation control stick (9) forwards, the fork rotates to the left.
Pull the left and right rotation control stick (9) backwards, the fork rotates to the right.
k. Fork rotation and lateral movement (left/right)
Push the left and right joint operation control stick (14) forwards, the fork rotates to the left, and the
lateral movement frame moves to the right.
Pull the left and right joint operation control stick (14) backwards, the fork rotates to the right, and the
lateral movement frame moves to the left.
l. Malfunctions
If there are any malfunctions or the truck is inoperative, please stop using the truck and activate the
emergency button (1) by pressing it. If possible, park the truck in a safe area, turn the key switch (2)
counterclockwise and remove the key. Immediately inform the manager or call your service. If necessary,
remove the truck out of the operating area by using dedicated towing/ lifting equipment.
When the truck breaks down, stop using it immediately and put a label for indication;
When the truck breaks down, the wrench indicator at the bottom of the display will be on. CURTIS
hand-held unit can help to find out the fault cause.
m. Emergency
In emergencies, press the emergency button (1) immediately in case of loss of control and other
emergencies.All electrical functions will stop.
If the truck fails to lower the lifted fork, please use a 6mm Allen-wrench to unscrew the screw
(emergency descent) shown in the figure below to lower the fork.
