• Height rod installation
• Wheel installation
• Hand post installation
Remove all components from the shipping box (shown in Figure 2-1) and lay out in a convenient place.
Figure 2-1. Box Contents
2.1 Pillar Installation
Prior to assembly, you’ll need the following tools to finish assembling the Mechanical Physician Scale.
• Multi-purpose tool (included)
• Wrench (included)
The pillar comes separate from the scale base and must be attached prior to use. Use the following steps to attach
the pillar to the scale base.
1. Set the scale base on a table or other convenient place.
2. Remove the twisty ties off the scale base as shown on the left hand side of Figure 2-2. Remove the cable
tie that holds the steelyard rod from shifting during transit (shown on right hand side of Figure 2-2).

3. Insert the pillar into the scale base assembly ensuring that the RLWS logo located on the weight beam
faces the scale base.

2.2 Steelyard Rod Connection
The steelyard rod is located inside the scale pillar. Once the pillar is attached to the scale base, the steelyard rod
must be attached to the bottom of the scale.
1. Lay the scale pillar on a table so that the scale platform hangs over the edge of the table and allows you
to access the bottom of the scale.
Figure 2-5. Connecting the Steelyard Rod to the Scale Base
2. Insert the hook part of the multi-purpose tool (included and shown above) to the small hole in the bottom
of the steelyard rod, and pull the hook of the steelyard rod with the hook of the multi-purpose tool to
connect it to the scale base lever as shown in Figure 2-5, then push the scale base lever towards the pillar
head, and hook the bearing of the steelyard rod on the pivot of the long lever.
Visually ensure that the force lever assembly linkage is centered and properly aligned. Occasionally
during shipping, alignment will become skewed. The linkage must be free floating in order for the scale
to weigh properly. The linkage can be seen by looking up underneath the top weigh beam if the scale is
slightly tipped to one side.

3. Place the scale gently back on the floor.

2.4 Wheel Installation
The Mechanical Physician Scale comes with sturdy wheels for easy portability. To install the wheels onto the
scale, use the following instructions.
Mounting the wheels upside down can create scale errors.
1. Align the angle iron of the wheel base to the scale platform as shown in Figure 2-9.
Figure 2-9. Attach the Scale Wheels onto the Scale Base
2. Use the screws and washers that are included with the scale to fix the wheel to the platform, adjusting the
angle iron at a level position, then tighten screws.
3. When moving the scale, hold the two side faces of the pillar to keep the front side of the platform away
from the ground.
