1. Set the scale base on a table or other
assembly area free from traffic and
obstructions.
2. Remove the tie that secures the steel rod
during transit (shown in Fig. 1).
3. Insert the pillar into the scale base (shown
in Fig. 2), ensuring that the AVAWEIGH logo
on the weight beam faces the scale base.
4. Using a Phillips screwdriver, screw in the
eight bolts and washers to secure the pillar
to scale base as shown in Fig. 3.

INSTALLATION PROCEDURE
5. Lay the scale on a table. Remove and discard the shipping tie wrap wires on the
underside of the scale carriage as shown in Fig. 4.

7. Push the long lever forward and hook the steel rod’s bearing on the long lever pivot.
NOTE: During shipping, a plug is installed to ensure that the force lever assembly
stays aligned, but the linkage may still come out of alignment. Visually ensure that the
force lever assembly linkage is centered and properly aligned. The linkage must be
free floating in order for the scale to weigh properly. If the scale is slightly tipped to
one side, the linkage can be seen by looking up underneath the top weigh beam.
8. Place the scale gently back on the floor.
6. Insert the wrench (included) into the small hole in front of the steel rod and pull the
rod hook with the wrench to connect it to the scale base as shown in Fig. 5. The steel
rod is located inside the scale pillar. Once the pillar is attached to the scale base, the
steel rod must be attached to the bottom of the scale.

HEIGHT ROD ASSEMBLY
WHEEL ASSEMBLY
To p
Bottom
1. Insert the slotted holes on the back of the height rod into the two bolts on the front
of the pillar as shown in Fig. 7.
2. Use the enclosed wrench to tighten the two hex-head screws.
Be sure not to over-tighten.
3. To raise or lower the height rod, press the red button at the top of the height rod.
1. Align the angle iron of the wheel base to the scale platform as shown in Fig. 8.
2. Use the screws and washers that are included to affix the wheel assembly to the
platform. Adjust the angle iron at a level position and 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.
NOTE: Mounting the wheels upside down can cause weighing errors.
5.
1. Ensure the scale is sitting on a level surface and slide the upper and lower weights to
the far left positions.
2. Gently hold the scale pointer with your finger so it is centered within the eye loop
area. Release the scale pointer and let it rise freely up or down.
3. If the pointer doesn’t remain centered, turn the zero adjustment screw
(shown in Fig. 9) using a flathead screwdriver until the pointer remains centered
within the eye loop.
After assembly, the scale must be zeroed prior to use.

PROBLEM POSSIBLE SOLUTION
Zero balance out
of adjustment
The weighing beam must be balanced so the pointer comes to a rest in
the center of the eye loop (shown in Fig. 9) when both poise weights are
set at zero (see page 1 for poise weight locaon). Follow zero adjustment
instrucons on page 5.
Beam does not move freely
Make sure the pointer is not touching the side of the eye loop, impeding its
range of travel.
Visually ensure that the linkage is centered and properly aligned.
Occasionally during shipping, the alignment will become skewed. The
linkage must be free oang in order for the scale to weigh properly. If the
scale is slightly pped to one side, the linkage can be seen by looking up
underneath the top weigh beam.
Plaorm rocks excessively Ensure scale is sing on a level surface. When you push down on any
corner of the plaorm, you should not feel any signicant rocking.
Beam does not move at all
during weighing
Weights are set higher than the person’s actual weight.
Reset the weights to a lower weight.
Make sure steel rod is properly connected and aligned as in Fig. 5
Scale is out of calibraon Recalibrate the scale by placing a known weight on the scale and turning the
zero adjustment screw unl the pointer remains centered within the eye.
