WARNING
Invacare slings and patient lift accessories are specifically designed to be
used in conjunction with Invacare patient lifts. Slings and accessories
designed by other manufacturers are not to be utilized as a component of
Invacareî™…s lift system.
Use of these products is prohibited and will void Invacareî™…s patient lift
warranty.
Use only genuine Invacare slings and patient lift accessories to maintain
patient safety and product utility.
Be sure to check the sling attachments each time the sling is removed
and replaced, to ensure that it is properly attached before the patient is
removed from a stationary object (bed, chair or commode).
1. Attach sling straps to the swivel bar. For proper attachment instructions refer to the
Sling Owner's Manual - Part No. 1023891.
NOTE: For improved accuracy on the 450 and 600 Reliant lifts, attach all sling straps to the
center hooks on both sides of the swivel bar. However, patient comfort may require a different
configuration of sling straps.
2. Press the ON/OFF key.
NOTE: The display will indicate the last weight that was measured. The word "LOCK" will be
seen in the display box.
NOTE: The ZERO key is pressed in order to avoid capturing the weight of the sling and the
hardware. If the ZERO key is not pressed the weight of the sling and the weight of the
hardware will be included in the weight displayed. NOT ZERO-ING OUT WILL GIVE A FALSE
READING OF THE USER'S TRUE WEIGHT.
3. Press the ZERO key. When the ZERO key is pushed the following will happen:
A. The scale will reset to zero and the word "ZERO" will appear in the display.
B. The lock function will then be turned off and the word "LOCK" will disappear
from the display.
NOTE: The scale is now active and continually updating the weight display.
4. Place the patient in the sling. For patient placement instructions refer to the Sling
Owner's Manual - Part No. 1023891.
WARNING
When elevated a few inches off the surface of a stationary object (bed, chair
or commode) and before moving the patient, check to make sure that the
sling is properly connected to the hooks of the swivel bar. If any attachments
are NOT properly in place, lower the patient back onto the stationary
surface and correct this problem - otherwise, injury or damage may occur.
5. Activate the lift mechanism to raise the patient until they are completely supported
by the lift.
