ACTUATOR REMOVAL AND REPLACEMENT 
 
 
WARNING!
GENERAL MAINTENANCE
To avoid personal injury, NEVER go under the lift platform or perform any 
maintenance on the equipment until the load is removed and the platform 
or scissors mechanism is securely blocked in the open position. See the 
"Lift Blocking Instructions" section. 
 
1. Securely block open the lift - see the "Lift Blocking Instructions”. 
 
2. Always shut off the main electrical switch, when blocked, to prevent someone from 
turning it on.
 
3. Disconnect the actuator by removing the bolts that connect the base of the actuator 
(s) to the lift legs.
 
4. Remove the actuator clevis pins from the rod end (on linear actuator lifts) and 
remove the actuator from the lift.
 
5. Re-installation of the actuator assembly is the reverse of above procedure. 
 
6. After checking all pins, mechanical components, and electrical control components 
to make sure everything is completely assembled and in working order, it is a good 
idea to check the lag bolts for tightness. 
 
7. Turn on the electrical supply and press the "UP" button to remove the maintenance 
device(s) (per the “Lift Blocking Instructions” section).
 
8. Cycle the lift several times to ensure it is working properly. 
 
9. LAST BUT NOT LEAST! 
Clean up the area. It’s part of the job as a service
technician and reflects on the work performed.
 
 
NOTE: This job should require one to two hours of time, depending on the experience 
of the service technician.
