Sign off on the hydraulic oil check

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.

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

Warning: This check requires trained personnel with PPE!

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.

Enter the nut torque without lubrication (410-540N.m)

Fit and lock the new cotter pin.

CAUTION: Model suitable for electrical driven machine.

Enter the torque of all the bolts without lubrication (90N.m)

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 noted replacement time and date.

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.
