Lingong Heavy Machinery Scissors Mobile Elevating Work Platform S2632E II

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.

This check is carried out every 25 hours or once a month, whichever comes first.

A hydraulic tank cover with unobstructed exhaust is essential to achieve good mechanical performance and service life of the machine. Dirty or clogged vent cap may lead to poor performance of the machine. It should be checked more frequently in a harsh working environment.

Remove the vent cap from the hydraulic tank cover.

Conduct ventilation installation.

Air can pass through the vent cap.

If the air cannot pass through the vent cap, clean or replace the vent cap. Continue with step 3.

CAUTION: During inspection of the ventilation and exhaust of the tank cap, the air shall be able to pass freely.

Clean the tank vent cap carefully with a mild solvent and dry it with low pressure compressed air.

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.

Check whether the bolts of the whole machine are loose and make abnormal noise

Check whether the circlip and gasket of the scissor arm are invalid

Check whether the emergency lowering device is normal

Check the platform, fork and chassis for deformation and open weld

Check whether the paint of the complete vehicle falls off

Check whether the safety identification is true or stained

Check whether the manuals and labels are missing, blurred or damaged

Check overall performance and various limit switches.

Replace the hydraulic tank vent cap.

1. Perform this step every 50 hours or quarter, whichever comes first.

2. 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.

2.1. Take out the hydraulic tank vent cap.

2.2. Renew the hydraulic tank vent cap.
