Setting the Limit Switches
Your lift is equipped with upper and lower limit switches. The vertical location of these switches may be adjusted to fit your application. Typically the upper limit switch will need to be adjusted so the platform will stop level with the upper landing. The lower limit will typically not need adjusting.
Step 1
Verify the emergency switch is in the ON position. Run the lift in the up direction until the platform floor is level with the upper landing. Disconnect the lift’s power (at the building’s circuit breaker for AC units, at the battery box for DC units) before going to the next step.
Warning: Moving components can cut and crush. Do not operate the lift if you are in close proximity to any drive components. Be aware that loose clothing or jewelry may catch on moving parts.
Step 2
Remove the screws at the top of the lift that attach the front cover.
Step 3
Remove the front cover by tilting it forward and lifting upwards. The bottom of the front cover sits on a pin on either side of the lift frame. Set the cover aside in a safe location where it will not get damaged.
Step 4
Loosen the bolts that attaches the upper limit switch assembly. Slide the assembly down the track until the lower switch in the assembly comes in contact with the lift’s car. You should hear the limit switch click as contact is made. Retighten the set screw fastening the limit switch assembly in place.
Step 5
Replace the front cover and secure it with the screws you removed in step 1.
Step 6
Step 7
Run the lift in the down direction for several inches. Next, run the lift in the up direction. Continue to press the up button until the upper limit switch has caused the lift to stop. Verify that the platform has stopped level with the upper landing. If it has not, readjust the limit until it is level.
