Lingong Heavy Machinery Scissors Mobile Elevating Work Platform S1932 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.

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.

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.

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.

Install the hydraulic tank vent cap.

Sign off on the ventilation system check

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.
