The digital MDSMELSCALE is designed to use with the lifts as shown above. The scale may be
set to read 0-700 lbs or 0-317 Kgs. The scale will not increase the weight capacity of the lift
and therefore never attempt to lift anyone whose weight is above the lifts’ safe working load.
For accurate reading a secure hardware fit is required therefore do not attempt to use other
scale brands on these lifts.
Each scale is calibrated at the factory prior to shipping. The calibration certificate is in the
bottom of the carton specific to the unit serial number printed on the right side of the scale.
The scale is powered by one replaceable 9-volt battery, which is stored inside the scale.
Removing the black rubber plug on the right underside of the scale will access the battery.
Replace batteries as required. Properly dispose used batteries.

•Use of the MDSMELSCALE will not increase the lift capacity of the lift. Always
refer to the lift safe working load limit and do not attempt to lift more than the
lifts’ load limit.
•Perform all lift procedures as described in your owner’s manual. Always check
that all parts are safely attached and secured prior to attempting a lift.
•Torn, frayed or damaged slings could fail and result in serious injury or death.
Check slings carefully prior to each lift and discard and replace any that show signs of wear
and tear. Never use a sling with a lower safe working load limit than the weight of the
resident/patient/user.
Prior to assembly please ensure all parts as noted above are present. Then follow these
step-by-step instructions:

HOW TO USE THE MDSMELSCALE
Step 1: Place the sling to be used for weighing on the spreader bar without patient/
resident/user.
Step 2: Press the On/Zero button on the scale faceplate to “zero-out” the reading (the weight
of the sling will remain zeroed out until the Off button is pressed)
Step 3: Press the “Kg/Lb” button to select the weight option you require.
Step 4: Carefully place the patient/resident/user in the sling and perform a lift so that all of
the weight is supported by the lift. Stabilize the movement of the sling after lifting.
Step 5: Press the “Operate” button to display the weight of the patient/ resident/user in the
previously selected Kg or Lb unit
Step 6: Lower the patient safely and either continue to next patient with same sling zeroed
out or change sling and repeat steps 1-5.
Step 7: Press the “Off” button to turn off the scale when weighing procedure
has been completed.
Step 8: Repeat Steps 1-7 for each subsequent weighing procedure.
MAINTENANCE
1. Always keep the scale in horizontal position.
2. Keep the scale in a cool and dry place.
3. Clean the scale with a damp cloth and avoid getting water inside the scale. DO NOT use
chemical/abrasive cleaning agents.
WARRANTY
There is a one year limited warranty against manufacturers defects, excluding normal
battery replacement.
* PLEASE HAVE WEIGHT READY FOR THIS CALIBRATION*
DO NOT ATTACH WEIGHT UNTIL INSTRUCTED BELOW!
1. Press and hold the On/Zero + Operate/Hold buttons at the same time, screen will count down
(9.9.9.9.9.,-8.8.8.8.8.,-----0.0.0.0.0 to zero, continue to hold for about 5 seconds), until screen shows
01211 then let go of the button and you should see “LF 1” on the screen.
2. Press the On/Zero button ONCE, and the screen will show “CAL 2.” Press the On/Zero button ONE
more time, and you should see dash lines appear.
3. When you see numbers appear and the dash lines are gone, change the weight on the scale using
the buttons below in order to set the amount of weight you have for the calibration. The weight will
display in kg. (Example: if you have a 10 lbs. dumbbell for calibration user needs to enter 4.5 kg on
the scale.)
Use the On/Zero button to change the positioning of the numbers. Use the Kg/lbs. button to change
numbers. (Make sure to enter each number from left to right correctly, because it will not allow you to
go back and delete.)
*Use below table if scale is stuck in a mode that you do not want it in for the calibration*
4. Once you have the correct weight on the screen for the calibration, press the On/Zero button once
and the screen will start flashing.
5. While the numbers are still flashing, hang the weight that you are using for the calibration from the
scale, WAIT 5 SECONDS, and press the On/Zero button once.
6. Dashed lines will appear on the screen, followed by the amount of weight that is on the scale.
FINAL STEP: If the weight is correct, the calibration is complete. If the weight is different, run
through the above steps from the beginning.
