Inspect for burned, scratched, corroded, bent or loose wires in the hydraulic valve block wire.

Inspect for burned, scratched, corroded, bent or loose wires in the wire in battery area wire in battery tray.

Inspect for burned, scratched, corroded, bent or loose wires in the interior of PCU box.

Turn the key switch to the PCU and pull out the red emergency stop button on the GCU and PCU.

Raise the platform to a certain height from the ground.

Move the safety arm to the middle of the scissor shaft sleeve and rotate it down to the vertical state.

If the hydraulic oil is contaminated, it may affect equipment performance and cause damage.

Is the oil stain separator test necessary?

If the hydraulic oil has not been changed for two years, it should be tested quarterly.

Did the hydraulic oil pass the quarterly test?

If the hydraulic oil fails the test, it should be changed.

Warning: Keeping the tire and hub in good condition is essential for safe operation and good performance. Failure of tires and hubs may cause the machine to tip over. If the failure isn’t found or eliminated in time, the machine parts will be damaged.

Check the tire tread and sides for scratches, cracks, punctures and other abnormal wear.

Check the hub for damage, bending and cracking.

Remove the cotter pin and check the nut torque.

CAUTION: New cotter pins must be used when reinstalling.

Fit and lock the new cotter pin. Nut torque without lubrication 410-540N.m

CAUTION: Model suitable for electrical driven machine.

Check the torque of all the bolts. Torque of the bolt without lubrication 90N.m

Lubricate the steering knuckle.

CAUTION: Disconnection of the battery pack on the machine shall be carried out when the machine is retracted.

WARNING: operation in a live circuit may result in serious injury or death. Remove rings, watches and other jewelry before operation.

WARNING: the sprayed hydraulic oil can penetrate the skin. During loosening of the hydraulic fitting, the speed should be very low, so that the oil pressure can gradually decrease. Do not let the oil spray out.

WARNING: Operation without oil may cause damage to the hydraulic oil pump. When filling the hydraulic system with oil, be careful to empty the tank. Do not allow cavitation of the hydraulic pump.

Verify whether the changing is necessary with an oil stain separator before changing the hydraulic oil.

If the hydraulic oil has not been changed for two years, it shall be tested once every quarter. If the test fails, change the hydraulic oil.

Open the installation tray of the hydraulic power unit.

Mark and disconnect the return pipe from the hydraulic filter to the hydraulic tank and remove the pipeline from the tank. Cover the pipe fitting to prevent dust.

Mark and disconnect the suction pipes of the hydraulic pump and tank, and take out the pipes. Cover the pipe fitting to prevent dust.

CAUTION: Replacement of the return filter element is essential for the good performance and service life of the machine. Dirty or clogged filters may affect the machine performance, and their continuous use will cause damage to parts. The filter element should be replaced more frequently in harsh working environment.

WARNING: scalding hazard Beware of hot oil. Exposure to hot oil may result in severe burns.

CAUTION: The return filter of the hydraulic tank is installed in the middle area between the function valve block and the hydraulic power unit.

Clean the hydraulic oil spilled around the filter and remove the filter with a wrench.

Disassemble the filter and renew the filter element.

Apply a layer of hydraulic oil to the filter sealing ring and tighten it with a wrench.

Use the marker pen to note the replacement time and date on the filter element replacement sheet.

Turn the key switch to the ground control, and pull out the red emergency stop button on the GCU and PCU.

Press and pull down the lift function selection button.
