D4-9 / D4-9X Four-Post Lifts 25 P/N 5900251 — Rev. A— October 2020
Installing the Safety Lock Release Mechanism
The Safety Lock Release Mechanism goes to all four Posts. To get from one end of the Lift to the
other, it is routed under the Powerside Runway.
You
must install the Handle next to the Power Post (it must be installed there because you have to
hold down the Handle and the Lowering Handle on the Power Unit to lower the Runways).
The components you will need to install the Safety Lock Release Mechanism are:
• Two Pivot Pieces. Pivot Piece attached to a Long Rod. One with the Handle attached, one with
no Handle. Each Pivot Piece connects a Short Rod to a Medium Rod on the outside of each
Crosstube.
• Two Short End Rods. Connect the Safety Release Assemblies on each Crosstube to the Pivot
Pieces on the ends of the Powerside Runway only.
• Two Medium End Rods. Connect to the other side of the Pivot Pieces and go to the Safety
Release Assembly.
• Eight Connectors. Make the connections to the Rods, four on the ends of each Crosstube.
• Two Spacers. Go between the Pivot Piece and the Crosstube. One Spacer per Pivot Piece.
• One Connection Piece. Connects the two Long Rods to each other under the Powerside
Runway.
• Two threaded Eye Hooks. Hold the two Medium Rods in place.
