6 Repair and Maintenance

Keep clean
 This unit should be cleaned with dry cloth frequently to
keep it clean. Before cleaning, first switch off the power to
ensure the safety.
 The working environment of this unit should be clean. In
case of dust in the working environment, it will speed up
the parts wearing and shorten the service life of the lift.
Every day:
 Before the operation, carefully check the safety
mechanism of the lift to ensure the electromagnet suction
and release action is proper, and the safety plate is in
good condition. When finding any abnormal situation,
make adjustment, repair or replacement immediately.
 Check to see if the connection between hydraulic cylinder
and carriage is proper, if the connecting nut between the
steel chain and carriage is loose or falling. Refer to Fig. 6.
 Check to see if the steel cable connection is proper, and if
the tension is at the optimum status.

Every month:
 Retighten the anchor bolts.
 Lubrication chains/cables.
 Check all the chain connectors, bolts and pins to ensure
correct installation
 Check all the hydraulic lines for wearing
 Check to see if the carriage and the inner side of the
column are properly lubricated. Use high-quality heavy
lubrication grease (lithium based lubrication grease).
Note: All the anchor bolts should be tightened
completely. If any screw doesn't function for some reason,
the lift can not be used until the bolt is replaced
Every six months
 Check all the movable parts for possible wearing,
interference or damage.
 Check the lubrication of all the pulleys. If the pulley has
dragging during the lifting and lowering, add appropriate
lubricant to the wheel axle.
 When necessary, check and adjust the balancing tension
to ensure the horizontal lifting and lowering.
 Check the verticality of the column.
Note: The inner corner of each column should be
lubricated with lubricant, to minimize the roller friction and
ensure the smooth and even lifting.
Maintenance of hydraulic system:
 Clean and oil change
In the six months after initial use of this unit, clean the
hydraulic oil tank and replace the oil, later clean the
hydraulic system once a year, and replace the oil. See
Fig. 7.
 Replace the seal
After this unit is put into operation for certain period, if
finding the oil leakage, carefully check it; if the leakage is
due to the wearing of sealing materials, immediately
replace the worn one based on the original spec. See Fig.
7 and Fig. 8.
