To quiet noise:
Verify that there is a white plastic guide at the end of the large screw of the actuator.
- Loosen the set screw that secures the top frame rod (see photo).
- Remove the 1/2" diameter rod that attaches the actuator adapter to the underside of the frame and allow the top frame to carefully "stand up".
- Use the foot pedal to retract the actuator completely. The end of the screw will be visible at the top end of the painted adapter tube. The guide will be a white ring around the top end of the black screw.
Remove the plastic guide.
- Loosen the set screw (see photo) that secures the actuator adapter tube to the ball nut of actuator.
- Unthread the adapter from the actuator.
- There is a roll pin that passes through the guide and screw. Punch it out with a hammer and punch.
- Replace the adapter tube and pin the top frame on the top end of the adapter tube. Make sure all set screws are tightened again.
