ASSEMBLY INSTRUCTIONS (CONT.)
Caution: It is recommended that the assembly be performed by two people. Use of a
chair is also recommended for the assembly process.
1.Carefully remove the scale platform and
pillar from the carton and place on a flat,
level, and dry surface. Locate the steel rod
at the base of the pillar. Remove the tie wrap
that holds the steel rod / finger pull loop to
the pillar.
2.Obtain a sturdy chair and place the top of
the pillar with the front side facing down on
the seat of the chair, as shown. Place the
platform/base perpendicular to the platform
with the front of the base resting on the floor
and the top of the platform/base facing the
top of the pillar. Remove the four pillar nuts
on the studs and set aside for use in step 3.
Align the four studs on the bottom of the
pillar with the four holes in the top of the
platform/base. Insert the studs into into the
platform/base.
Note: If a chair is not available it is
recommended that one person holds the
platform/base while another person handles
the pillar.
3.Access the underside of the scale base.
Obtain the four pillar nuts removed in step 2
and place onto the studs on the underside of
the scale base. Using the provided wrench,
tighten the pillar nuts to secure the pillar to
the base.
4.Grasp the finger pull loop on the end of the
steel rod and pull towards the lever
extension. Push the lever extension towards
the finger pull loop. Hook the steel rod to the
hole at the end of the lever extension.
Release the finger pull loop and ensure that
the steel rod and lever extension are hooked
together. Carefully position the scale to its
upright position. The scale is now
assembled. Refer to the next page to zero
balance the scale before first use.

OPERATING INSTRUCTIONS
Zero Balance Adjustment
Before first use, the scale needs to be zero balanced by following the instructions below. The scale
should also be checked and balanced periodically, particularly when moved.
Note: A flat head screwdriver is required.
1. Ensure that the scale is located on a hard, flat, and level surface. Step on and off scale several
times in order to align all internal parts.
2. Place both poise weights on the “0” value on both bars. The beam pointer should float gently up
and down, and not touch the top or bottom of the trig-loop.
3. If the beam pointer is not centered in the trig-loop opening, using a flat head screwdriver, rotate
the balance ball screw to correct the beam pointer. Turn the screw about ¼ turn forwards or
backwards and let poise bar settle. Based on which direction the poise bar moved turn ¼
forwards or backwards again and let poise bar settle until the pointer is centered in the trig loop.
Weighing Instructions
1. Set the upper and lower poise weights to indicate the patient’s approximate weight.
2. Have patient step onto the scale. Ensure they are positioned directly in the center of the
platform. Continue to adjust the upper and lower poise weights until the pointer is centered.
Note: It is not necessary for you to wait for the pointer to stop moving in order to read the correct
weight. As long as the pointer is moving equally within the trig-loop opening, the patient’s weight
can be determined.
3. Observe the location of the indicator arrow built into each poise weight. Read the value on the
poise bar, closest to the indicator arrow.
Note: For easy identification, pounds (lb) have black graduations on a silver background, located on
the upper portion of each poise bar; kilograms (kg) have silver graduations on a black
background, located on the lower portion of each poise bar.
4. Add the indicated reading of the upper poise value to the indicated reading of the lower poise
value. The total amount is the patient’s weight. See the example on the next page.
Note: To transport your scale, acquire the optional wheel bracket (Item # 55000). Please refer to the
“Transportation” section on page 9 for assembly instructions.
Note: To increase your scale’s capacity, acquire the optional counterweight set (Item # 55090).
Please refer to the “Counterweight Instructions” section on page 10.

TRANSPORTATION
A wheel bracket is included if purchased as model 400KLWH. If purchased as model 400KL an
optional wheel bracket can be purchased separately (Item #55000). Follow these steps to install
the wheel bracket:
Tools Required (not included)
Adjustable wrench or 10 mm wrench
1.Remove the mounting screws that attach the
clamping plate to the wheel bracket.
2.Gain access to the underside of the scale
base by carefully tipping the scale forward
until the pillar is resting on the floor. Position
the clamping plate inside the base by
aligning the holes in the clamping plate and
base.
3.Position the wheel bracket onto the base by
aligning the holes in the wheel bracket with
the holes in the clamping plate.
4.Insert the mounting screws through the
wheel bracket and into the clamping plate.
Using a wrench, tighten the mounting screws
to secure the wheel bracket to the base.
Carefully tip the scale to its upright position.
To transport the scale, tip the pillar backwards until the scale is resting on the wheel bracket.
Carefully move the scale to its new location.

COUNTERWEIGHT INSTRUCTIONS
In order to increase the scale’s capacity to a maximum value of 490 lb / 210
kg, the counterweight set (Item # 55090), must be acquired. If purchased as
model 400KLCW the set is included with the scale.
In order to employ the counterweight set, refer to the instructions
below. Contact technical support with any questions or concerns regarding
the use of the counterweight set.
Note: These instructions are for 400KL models with non-rotating poise bars. Use counterweight
55080 for pounds and counterweight 55085 for kilograms.
Counterweight Instructions for Weighing in Pounds (lb)
Note: The 100 lb (55080) counterweight is required when weighing a patient who is over 390
lbs.
Counterweight Instructions for Weighing a Patient 391 - 400 (lb)
1. When a patient weighs between 391 - 400 lb, place the lower poise weight at 250 lb.
2. Place the 100 lb (55080) counterweight on the 3rd notch from the left, between the 50 lb and
100 lb value.
3. Adjust the upper poise weight until the pointer is centered. The poise bar will center in the
trig-loop.
4. Read and record the weight. To read the patient’s weight, add the weight value indicated on
the upper and lower poise bars, as well as an additional 100 lb. See page 15 for a
counterweight conversion chart.
