1. It is preferable to set the scale base on a box or other item to keep the scale base up off the floor. Tip the scale

base on its side.

Figure 2-1. Scale Base on its Side

2. Place wheel axles through the holes in the frame.

Figure 2-2. Run Axle Through Scale Base Frame Holes

3. Place the wheels and washers on the axles.

Washers must be placed on the insides of the wheels next to the scale frame.

Wheels must be placed with the extended hub next to the scale frame.

4. Place the washers and wheels against the frame and insert cotter pins in the holes in the axles. Bend the cotter

pin with pliers to prevent it from slipping out.

5. Finish the wheel assembly by securing axles to frame by securing wheel axle rods with axle locking bolts and

lock nuts. Center the axle and tighten bolt and locknut.
