The user must perform daily check. Daily check of safety system is very important – the discovery of device failure before action could save your time and prevent you from great loss, injury or casualty.

· This machine should be constantly wiped and clean up ,and keep it clean. Before wiping, cut the power, ensure security.

· Check whether oil hose well connected. No leakage is allowed.

· Check the electric connections. Make sure all connections are in good condition.

· Check if safety teeth and safety block matched well or not.

6.2

Weekly checking items

· Check the flexibility of moving parts, and lubricate all pivot pins.

· Check whether the expansion bolts well anchored.

· Check the working conditions of safety parts.

· Check the amount of oil left in the oil tank. Oil is enough if the carriage can be raised to highest position. Otherwise, oil is insufficient.

13

6.3

Monthly checking items

· Check whether the expansion bolts well anchored.

· Check the tightness of the hydraulic system and screw firm the joints if it leaks.

· Check the lubrication and abrasion circumstance of moving parts.

6.4

Yearly checking items

· Check the lubrication and abrasion circumstance of moving parts.

· Empty the oil tank and check the quality of hydraulic oil.

· Wash and clean the oil filter.

6.5

Every three years or more than 5,000 routine maintenance items

· Replace the pin, bearings, tubing connector components.
