• Check the amount of oil left in the oil tank. Oil is sufficient if the carriage can be raised to highest position. Otherwise, oil is insufficient.
• Check whether the expansion bolts are well anchored.

Monthly checking of items

• Check whether the expansion bolts are well anchored.
• Check the tightness of the hydraulic system and screw the joints firmly if it leaks.
• Check the lubrication and abrasion circumstances of moving parts.

Yearly checking of items

• Empty the oil tank and check the quality of the hydraulic oil.
• Wash and clean the oil filter.
