MAINTENANCE 
SCHEDULE 
PERFORM THE FOLLOWING MAINTENANCE 
Annually 
The entire lift should be inspected yearly (more frequently for severe use applications) 
by your factory authorized service representative.
 
Every Two 
Years 
Change hydraulic fluid.  Use 4 gallons (15 liters) of Dexron II or III transmission fluid. 
NOTE: Oil must be filled when the lift is in its fully lowered position. 
Drain fluid from reservoir by removing magnetic plug on front of reservoir with the lift 
lowered completely. 
Clean any metal particles that may be on the plug before replacing. 
 
NOTE:   The suggested maintenance above is for normal working 
conditions.  Equipment exposed to unusually dirty or harsh 
corrosive conditions such as heavy winter road salt may 
require more frequent maintenance and service. 
If any of the conditions described above are observed before, during, or after 
operation of the lift, the operator shall stop using the lift and report the condition to 
the supervisor, employer or owner.  The lift shall not be used until the cause of the 
problem has been determined and the appropriate repairs have been made by 
qualified automotive lift personnel.
