• Lift platform to the highest location and press the lift function selection button. Result: the alarm goes off.
Result: No alarm goes off. Calibrate the platform overload system.
6) Lower the platform using the manual lowering function until the platform is retracted.
7) Carefully remove the short circuit wires from the upper limit switch.
8) Raise the platform to the highest location and press the lift function selection button. Result: No alarm
goes off. The system function is normal. Result: the alarm goes off and the platform overload system is
abnormal. Eliminate the malfunctions of the limit switch, the cable, the installation bracket and the like or
calibrate the overload system.
9) Lower the platform to a height of approximately 3.2 m above the ground.
10) Lift the safety support, move it to the centre of the scissors housing and turn it up until it's vertical.
11) Lower the platform height until the safety support is completely against the shaft housing.
Warning: risk of crushing
Place your hand on the correct position of the safety support when lowering the platform.
12) Connect the limit switch cable to the original status and install the limit switch cover.
13) Install the limit switch base valve.
14) Install the platform limit switch base valve.
15) Raise the platform slightly and restore the safety support to the installation position.
16) Lower the platform to the retracted position.
C-2 Replacing the outlet valve of the hydraulic oil tank
1) This step must be performed every 500 hours or every 6 months, whichever comes rst.
2) The hydraulic oil tank is a ventilated oil tank. There is an air lter in the outlet valve, which can be blocked.
If the outlet valve has a malfunction or is installed incorrectly, the component may be damaged if impurities
enter the hydraulic system. Frequent inspection is required for control of the poor working environment.
• Remove the outlet valve from the hydraulic oil tank.
• Install a new outlet valve of the hydraulic oil tank.
12.12 Steps of checklist D
D-1 Inspection for wear-resistant sliding block of scissor arm
1) This step must be performed every 1000 hours or per year, whichever comes rst.
2) The condition of the wear-resistant sliding block of the scissor arm is essential for the safe operation of
the machine. The wear-resistant sliding block can cause component damage and possible risk.
3) Check the wear-resistant cushion when the platform is retracted.
• Measure the distance from the outside section of the steel tube of the battery chamber to the non-rotating
end of the surface of the base panel. Result: the measured value is greater than or equal to 24 mm. Perform step
2. Result: the measured value is less than 24 mm. Replace the wear-resistant sliding block.
