6�1 Daily checking items before operation
•
The user must perform daily check. Daily check of safety lock system in very important – the discovery of device failure
before action could save time and prevent great loss, injury or casualty.
•
Before operation, judge whether the safety locks are engaged by sound.
•
Check whether oil hose well connected and whether it leaks or not.
•
Check the connections of chain and steel cable and check the power unit.
•
Check whether expansion bolts are firmly screwed.
•
Check if arm lock works well or not.
6�2 Weekly checking items
•
Check the flexibility of moving parts.
•
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.
•
Check whether expansion bolt s firmly screwed.
6�3 Monthly checking items
•
Check whether expansion bolts are firmly screwed.
•
Check the tightness of the hydraulic system and screw firm the joints if it leaks.
•
Check the lubrication and abrasion circumstance of axial pins, carriages, lifting arms and other related parts and replace
in time with new ones if they failed to work well.
•
Check the lubrication and abrasion circumstance of steel cable.
6�4 Yearly checking items
•
Empty the oil tank and check the quality of hydraulic oil.
•
Wash and clean the oil filter.
IMPORTANT
If users strictly follow the above maintenance requirements, the lift will keep in a good working
