6.Tighten the screws firmly with a 19mm wrench.
7.Insert the pin assembly into the hole (Figure 2). You may need to rotate it until it seats properly in the hole.
8.Install a flat washer and cast iron handle (Figure 2) to the threads of the top screw as shown, by screwing the handle down clockwise onto the screw threads.
9.In the area above the pin, remove the hex nut from the screw with a 19mm wrench, but leave the flat washer in place. In place of the hex nut, install the cam handle (Figure 2). Screw the cam handle clockwise onto the threads (the cam handle will contact the pin on each rotation and push the pin downward.) Tighten the cam handle.
10.Loosen the hex nut (A, Figure 3) with a 12mm wrench, and back off the set screw (B, Figure 3) with a 4mm hex wrench, until the shaft of the handwheel can be inserted freely into the hole in the bracket (Figure 3). The handwheel should be positioned so that the pinion on its shaft is approximately centered with the keyway of the bracket.
11.Turn the set screw (B, Figure 3) clockwise into the shaft just enough to prevent the handwheel from slipping out. Do not overtighten the set screw. Tighten the hex nut (A, Figure 3).
12.Loosen the handle above the bracket (Figure 4).
13.The end of the horizontal arm that has the rack extending to the end will be inserted into the bracket. Insert the horizontal arm, with the rack pointed downward, into the bracket. The rack will fit through the keyway in the bracket. See Figure 4. Continue to push the horizontal arm into the bracket while slightly rotating the handwheel counterclockwise, until the rack and pinion mesh. The horizontal arm can now be moved into the bracket by rotating the handwheel.
14.Install the elevating column onto the horizontal arm (Figure 5). Make sure the horizontal arm slides all the way into the sleeve of the elevating column (The end of the rack on the horizontal arm will almost touch the sleeve). Check that the elevating column assembly is in the vertical position. Tighten the two screws on the sleeve (Figure 5) with a 19mm wrench.
15.Install a flat washer and handle on the screw of the elevating column (Figure 5).
