OPERATION INSTRUCTIONS
Preweighing the Stretcher
1. Make sure the scale is free of load (nothing is hanging from it), including the stretcher.
2. Press the ON/OFF button to turn the scale on.
3. Wait until ”000
Lb00oz” and “ZERO” on the left side of the display will appear. The
scale will remember the last amount that was tared, so if the weight of the stretcher
had previously been tared, the scale will display a negative weight when it is turned
on again.
Note
: The ‘ZERO’ sign will show on the upper left side of the display only when the scale is free
of load, including the stretcher.
4. If the weight of the stretcher is known, enter the TARE value according to instructions in
the “Menu”, para 02. If the stretcher’s weight is unknown, place the stretcher only on the
scale; press REWEIGH. Enter the Automatic TARE by pressing the TARE button. Display
will read ”000
Lb00oz”.
Note
: Once the tare is set the “TARE” sign will appear in the upper right side of the display.
Placing Patient in Stretcher
1. After setting the stretcher’s weight as tare, take the stretcher off the lifter. The display will
now show a negative weight, equivalent to the weight of the stretcher.
2. Lay the stretcher on a bed or on any other stable surface you can use to lay the patient
you wish to weigh.
3. Carefully move the patient to a lying position on the stretcher.
Note: lay the patient’s center mass as close as you can to the center of the stretcher.
4. Wheel the lifter scale close to the stretcher and lower the boom with the hoops as far as 5-
10” (12 cm -25 cm) from the patient’s body.
5. Connect the four hanging loops of the stretcher to the four hooks at the end of each
Stretcher Hoop, making sure that the loops are hanging freely from the four hooks.
Note: Make sure both hooks connecting the load cell assembly beam lie on the lifter boom. If
only one of the hooks lies on the beam it can cause inaccurate readings of weight.
6. Tighten the hydraulic control valve knob by turning it clockwise. The control valve knob is
located on the Pump near the Pump handle.
7. Use the Base Adjustment Lever to widen the Lifter Base. The Base must be spread to the
widest possible position to maximize stability.
8. Pump the hydraulic Pump handle to lift the Stretcher and patient until the entire Stretcher
is hanging from the Stretcher Hoops and is not touching the bed or any other object. Do
not lock the Wheel on the Lifter Base. If needed, the Base will move slightly to adjust for
balance.
Caution: Never move patient away from bed or leave patient unattended.
Taking Weight Measurements
1. The scale will calculate the patient’s weight. Depending upon the movement of the
stretcher, the scale may take several seconds to lock into the weight. We recommend
reweighing after the patient is lying still on the stretcher by pressing the REWEIGH button.
2. After weight measurement is obtained and recorded, lower the Stretcher and the patient to
the bed. Open the hydraulic pump control valve knob by turning it counterclockwise very
slowly to control the descent.
3. Guide the patient and Stretcher down onto the bed.
