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.4 
 
Check to see if the steel cable connection is proper, 
and if the tension is at the optimum status. 
 
  
 
 
  
 
Fig 4 
Every month: 
 
Retighten the anchor Bolt s. 
 
 
 
 
 
 
 
Lubricate chains/cables. 
 
Check  all  the  chain  connectors,  Bolt  s  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 GB7324-87). 
  Note: All the anchor Bolt s 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. 5. 
 
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. 5
