Lingong Heavy Machinery Scissors Mobile Elevating Work Platform S4046E II

Monitor whether the system pressure is normal

Check whether the lift pressure system is normal

Check whether the steering system pressure is normal

Check whether the running system pressure is normal

Check whether any oil pipes and joints are loose

Check the oil cylinder for oil leakage

Check each spool for oil leakage

Check whether the fork oil pipe is fixed firmly

Check whether the walking oil pipe fixing clip is loose

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.

Upload a photo of the filter with the new element installed.

Enter 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.

Warning: This procedure should be performed every 50 hours or quarterly, whichever comes first.

The hydraulic oil tank is a vented tank. There is an air cleaner inside the vent cap, which may become blocked over time. In case of vent cap failure or improper installation, once impurities enter the hydraulic system, component damage may occur. The vent cap should be checked frequently especially in harsh working environment.

Hydraulic tank vent cap removed?

Hydraulic tank vent cap renewed?

DANGER: electric shock/explosion hazard. Do not wear rings, watches and other jewelry.

Check whether the ground wires under the chassis are missing or damaged.

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

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.

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.
