The Patient Weight Scale is intended to be operated entirely by a caregiver. The patient should
not perform any function relating to the control of the scale, sling or lift. Additional caregivers may
be required with certain patients or situations.
If the Patient Weight Scale becomes soiled or contaminated it can be cleaned following the
instructions found in the “Maintenance” section of this guide.
Inspect the Patient Weight Scale carefully before each use. If structural fatigue, erratic readings
or other damage is visible or suspected discontinue use immediately.

Always make sure the casters on the lift are unlocked during the weighing procedure.
Do not leave the patient unattended during the weighing procedure.
Operating the Patient Scale
1. Follow the instructions for operating the lift and sling.

3. Ensure the scale is clear of any obstructions, is hanging vertically and is free to pivot at both the
top and bottom connection points.
4. Press the “Zero” button to set the system to “0.0”. A “0” will pan across the screen for a couple
seconds. Display will then read “0.0”. See “Fig. 1”
5. Press the “Lb/ Kg”button to choose the desired mode. See “Fig. 1”
6. Remove the sling and following the sling instructions position the patient in the sling. Reattach
the sling to the sling bar ensuring the scale is hanging vertically and is free to pivot.
7. Carefully lift the patient and when the patient is fully supported by the lift and any motion has
stabilized, press the “Operate” button to display the patient weight. Do not touch the patient or
sling during this step.

Maintenance
A single 9 volt battery powers the Patient Weight Scale. A lithium battery should provide approximately
3,000 readings before replacement is needed. A “lowbat”indicator (see “Fig. 2”) will appear in the
display when replacement is needed. Remove the two screws on the battery access cover to replace the
battery.
The scale can be cleaned with a cloth dampened with water or a mild cleaner. Do not allow liquids to
enter the scale housing as damage to the unit will result.
The scale contains no user serviceable components and should be serviced by qualified personnel only.
Any unauthorized tampering will void the warranty.
