The oil level should be checked frequently and replenished promptly.

Spreaders must be checked regularly.

Mainly check the rope groove wear, whether the rim cracks and whether the pulley stuck on the shaft.

Check the rim and tread regularly, and replace the new one when the rim portion wears or cracks to 10% of the thickness.

When the difference between the diameters of the two driving wheels on the tread exceeds D/600, or if serious scars occur on the tread, the vehicle should be renewed.

Each class should be checked once.

The brake should act accurately and the pin must not be stuck. The brake shoe should fit the braking wheel correctly, and the clearance of the brake shoe should be equal when the brake is released.
