When charging, pull out the power socket and connect the plug of the charger to the movable socket with the handle. After charging, reset the power socket.
(6) Key switch
This switch function is to control the circuit on and off.
Seven. ammeter
When the key switch is in the open state, the meter displays the battery balance, a total of ten cells, when the leftmost diode exchange flicker, indicating that the battery is insufficient, the battery needs to be charged.
3、Driving Operation:
I. Start
Please proceed in the following order, otherwise the electric pallet truck will not run:
(1) Make sure the power socket is firmly plugged in.
(2) Turn the key switch to the open position.
(3) Ensure that the battery pack has enough power.
Long time low potential operation of electric pallet truck, damage battery life. Do not start the forklift before battery charging is complete.
(4) The manipulator arm is down from the top position and should be between the top and bottom ends
(5) Correctly select the driving direction and control the speed in the ideal state. Slowly accelerate to ideal speed.
Do not operate electric pallet trucks with serious functional defects that endanger safety. Before working every day, you should first check the following safety features:
※ Speaker function is normal.
※ Operating function is intact.
※ Brake function is normal.
※ Hydraulic function is normal.
II. Braking
(1) When the manipulator arm is moved to the top or bottom end, the forklift truck realizes electrified braking.
(2) When the direction switch is turned to the reverse position during normal operation, the electric braking function can be performed. Controlling the running speed can control the power of the traveling electric mechanism.
(3) Parking: Stop the electric pallet truck by releasing the driving direction switch and returning it to the neutral position.
(4) Air gap adjustment: In the case of brake power off, by adjusting the three hollow screws and brake mounting screws, the air gap between the stator and the armature is adjusted to the rated value "Z" with the help of the plug, paying attention to ensure that the air gap in all directions is the same. Then lock the brake mounting screw.
(5) Re-adjustment of the air gap: the rated air gap Z will become larger due to wear. In order to ensure that the brake has sufficient braking torque, the air gap must be re-adjusted before reaching the maximum air gap value. The air gap can be adjusted several times, and when the thickness of the friction brake disc reaches the minimum allowable thickness, the friction brake disc must be replaced. The noise value of the brake is relevant, and in applications requiring very low noise, it is recommended to re-adjust the air gap within the maximum range of the air gap. If the air gap exceeds the maximum air gap value, the pilot brake may not be released, the friction brake disc is burned out, the braking force or the holding force is reduced, and even lead to major accidents. Therefore, it is necessary to check and adjust the air gap, and note that the power supply of the device must be disconnected.
III. Turn
(1) The steering is controlled by the manipulator arm, and the steering Angle can be any position within 90° in the left and right directions.
(2) When the electric pallet truck encounters obstacles, it should not be forced through, and it can turn the control arm to move forward or backward to bypass the obstacles.
Do not allow the wheels to slip.
If the operator's hands or shoes are stained with oil, it is easy to make mistakes and lose control of the forklift, so you should wipe your hands or shoes before driving.
IV. Parking
(1) Release the direction selection switch.
(2) The cargo fork is lowered to the lowest level so that there is no system pressure in the hydraulic system.
(3) Release the control arm and the control arm will automatically return to the parking brake position.
(4) Turn the key switch to the key position.
Unauthorized driving is not allowed.
If you leave, please take the key with you.
