2. Attach the rod end of each cylinder to the intermediate frame support tube. The cylinder muffler should face
upward toward the scale.
3. Adjust each cylinder rod until it is approximately 1" from the fully-retracted position (Figure 2-2, D). Place
the pivot brackets (Figure 2-2, E) against the pit floor and use them as templates to mark the mounting hole
locations. Be sure the air cylinders are parallel with one another and square with the intermediate frame sup-
port tube.
4. Drill holes, install anchors, and secure the cylinder pivot brackets to the pit floor.
5. Attach the main air line to the inlet side of the regulator (Figure 2-2, F). Attach the air line from the outlet side
of the regulator to the input fitting on the pneumatic control box (Figure 2-2, G).
6. Attach the air lines from the output fitting on the pneumatic control box to cylinders. Apply 85-100 psi air
pressure to the cylinders. Check for air leaks.
7. Place the platform scale onto the intermediate frame (Figure 2-2, H), making sure feet sit on corner pads with-
out rocking. Adjust feet as necessary so the platform is level to within

8. Feed the load cell cables through the conduit. Leave a strain relief loop to allow enough cable for free move-
ment of the scale in the lifted position without tension in the cables (Figure 2-2, J).
Route the load cell cables on the same side as the hinge mechanism.
9. Route the load cell cables through the fittings in the junction box (Figure 2-2, K). Wire the cables to the junc-
tion box according to the corner numbering diagram (Figure ) and load cell wiring chart (Table 2-3). Coil and
store excess cable before hooking up to junction box.
Do not cut excess load cell cable. Do not store the excess cable in the scale pit.
10.Adjust speed during the lift cycle using the up speed adjustment screw (Figure 2-2, L) in the pneumatic con-
trol box. Once you have achieved the desired speed, tighten the lock nut. Adjust descent speed using the down
speed adjustment screw (Figure 2-2, M), then tighten lock nut.
Make sure the scale opens and closes gently to prevent damage to load cells.
Do not work under the raised scale or place body parts under a raised scale without the safety bar
properly positioned. Position the safety bar in the corner of the pit coping as shown in Figure 2-2, N.
Release the pressure on the cylinders to allow the frame to rest on the safety bar.
