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

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

Note the replacement time and date on the filter element replacement sheet

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.

Perform this step every 100 hours or 6 months, whichever comes first.

The quality of the scissor arm wear-resistant block is crucial to the safe operation of the machine. The use of worn wear-resistant slider may cause damage to components and unsafe work risks.

Check the wear washer when the platform is retracted.

Measure the distance from the inner link tube on the battery box side of the non-steering end to the floor plane.

If the measurement result is less than 24 mm, replace the wear-resistant slider.

Measure the distance from the fork inner link tube at the battery side on the non-steering end of the machine to the plane of the floor slide.

Result of the second measurement

If the measurement result is less than 24 mm, replace the wear-resistant slider.

This inspection shall be conducted every 25 hours or every month, whichever comes first.

The quality of the steering knuckle copper washer is crucial to the safe operation of the machine. The use of worn copper washer may lead to component damage and work hazards.

Check while the platform is retracted.

Measure the distance between the chassis bushing and the upper cover plate of steering knuckle

If the measurement result is less than or equal to 9 mm/0.35in, replace the nylon gasket inside the steering knuckle.

If the measurement result is more than 9 mm/0.35 in, there is no need to replace the nylon gasket inside the steering knuckle.
