450KL ASSEMBLY INSTRUCTIONS (CONTINUED)
Assembling the 450KL Scale (Refer to Figures 1-6 on pages 7-9)
Caution: It is recommended that the assembly be performed by two persons.
1. Carefully remove the scale platform and pillar from the carton. Place the scale platform and
pillar on a flat, level, and dry surface. Using a table can be helpful for assembly of 450KL
scale (see Figures 1 & 5 on pages 7 & 9).
2. Remove the four pillar nuts and wrench from the carton.
3. Locate the steel rod at the base of the pillar (see Figures 4, 5 & 6 on pages 8 & 9).
4. Cut the tie wrap that holds the steel rod to the pillar studs (see Figure 3 on page 8).
5. Insert studs into the four holes provided in the scale platform (see Figure 2 on page 7).
6. Tip the scale platform at an angle, resting the top of the pillar on any convenient support.
Using the wrench provided, secure the pillar to the scale platform with the four nuts (see
Figures 4 & 5 on pages 8 & 9).
7. Pull the steel rod toward the base of the scale platform by grasping the finger pull loop on the
steel rod end (see Figures 4, 5 & 6 on pages 8 & 9).
8. Push the lever extension toward the pillar with your hand (see Figure 4, 5 & 6 on pages 8 &
9).
9. While holding this position, 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 is hooked
together.
10. Carefully position the scale to its upright position.
11. The scale is now assembled and is ready for use (see Figure 1 on page 7).
Note: To transport your scale, acquire the optional wheel bracket (Part Number # 55000). Please
refer to the “Transportation” section for assembly instruction.

TRANSPORTATION
Preparing a 450KL Scale for Transportation (see Figures 7-10 on pages 11 & 12)
This scale can be easily assembled with a wheel bracket (Part Number 55000, see Figure 7 on
page 11) for storage, or for transport from one room to another. This scale does not include
55000 Wheel Bracket, and must be acquired separately. To prepare the scale for transport,
follow these steps:
Caution: It is recommended that the assembly be performed by two persons.
1. Remove the mounting screws attaching the clamping plate to the wheel bracket. (see
Figure 8 on page 11)
2. Tip the scale forward until top front of the pillar is resting on the floor.
3. Position the clamping plate inside the base, and align the clamping plate, wheel bracket,
and base assembly holes. (see Figure 9 on page 12)
4. Install the mounting screws through the wheel bracket, base, and clamping plate.
Tighten the mounting screws securely. (see Figure 10 on page 12)
5. Carefully tip the scale to its upright position.
6. To transport the scale, tip the scale pillar back until the scale is supported by the wheel
bracket. Carefully move the scale to its new location.

OPERATING INSTRUCTIONS
Zero Balance Adjustment
The scale should be checked periodically, particularly when moved, by following the instructions
below:
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, rotate balance ball screw to
correct the beam pointer.
Weighing Instructions (see Figures 11–14 on pages 14 & 15)
1. Set the large and small poises 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 small and large 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. The patient weight can be recorded in either pounds or kilograms.
4. Observe the location of the indicator arrow built into each poise weight. Read the value on
the poise bar, closest to the indicator arrow.
5. Rotate the upper and lower poise bars to measure in either pounds or kilograms. Ensure
that poise bars are locked after being rotated into position.
6. For easy identification, pounds (lb) have silver graduations on a black background, located
on one side of the poise bar (see Figure 11 on page 14); kilograms (kg) have black
graduations on a silver background, located on the other side of the poise bar.(see Figure
12 on page 14)
7. Add the indicated reading of the small poise value to the indicated reading of the large poise
value. The total amount is the patient’s weight. (see Figures 13 and 14 on page 15)

HEIGHT MEASUREMENT INSTRUCTIONS
Note: Use caution when sliding height rod up and down. The rod should move
smoothly, do not move the rod in a jerking motion.
Note: Fold headpiece down when not in use.
Height Measurements (Refer to figures 24-30)
Note: A patient needs to be a minimum of 23-5/8” (600mm) in height for the height to be
accurately measured.
1. Raise the headpiece above the patient’s head. (see Figures 24 and 26)
2. Position the patient against the height rod.
3. Ensure that the patient’s posture is upright, and that the patient’s head is straight and level.
4. Push the headpiece down until it rests on the patient’s head. (see Figures 25 and 27)
5. Determine the patient’s height by reading the value on the measuring strip nearest to the
line on the indicator (see Figures 28 – 30 on page 24).

balance
The balance ball must be balanced such that the

when both poise weights are set at “0” value.
Ensure that the large and small poise weights are
firmly against the shoulder of the beam.
Adjust the balance ball screw by turning the screw at
the left end of the bar until balanced.

Check if the pointer is touching the side of the trig

calibration.
The scale can be recalibrated by loosening the lock
screw at the end of the long lever in the bottom of
the base with a ¾” hexagon socket wrench and
moving it outward (longer) in the elongated slot to
decrease the indicated weight or inward (shorter) to
increase the indicated weight. One sixteenth inch
movement of the screw will change the indicated
weight by approximately one-quarter pound per 100
pounds.
Troubleshooting
Before contacting service personnel, refer to the following instructions to check and to correct
any failures for incorrect weight measurements.
The accuracy of the 450KL scale when calibrated at the factory is within +/- 0.1kg or ¼ pound.
For the most accurate weight measurement, use the scale on a hard level surface and stand in
the center of the platform. If the error seems excessive, check the following:
