3. SAFETY
ATTENTION!
Before putting the device into use, please read with care the information given in the Operating
Instructions. They contain important instructions for installation, proper use and maintenance of
the device. The manufacturer shall not be liable for damages arising out of failure to heed the
following instructions:
WARNING!
IMPORTANT DIRECTIONS
The assembling of RS300 dynamometer must be effected by skilled operators only and
before the use be sure that all hanging sick lift elements, dynamometer and sling are
properly assembled, to weight the patient on safety conditions. A faulty assembling of
these elements could cause the risk of falling with serious consequences for the patient.
After assembling phase and before weighing operations, the operator must be sure that:
•RS300 dynamometer and the sling are on VERTICAL POSITION
•During weighing operation the hanging sick lift scale is not moving.
•The operator must ALWAYS follow and hold the sling of the patient during lifting
phase, to avoid torsion and sudden movement of both dynamometer and sling that
could cause breakages and irreparable damages, with the risk of serious
consequences for the patient.
•DO NOT MOVE the hanging sick lift scale when the patient is leaned.
During weighing phase by means of RS300 dynamometer, the operator must be sure that
the patient remains still, to avoid any instruments torsion and the following uncorrect
weighing.
After weighing phase the operator must ALWAYS follow and hold the sling of the patient,
to avoid torsion and sudden movement of both dynamometer and sling that could cause
breakages and irreparable damages, with the risk of serious consequences for the patient.

6. WEIGHING OPERATION
Before reading detailed instructions on how to use all the weighing functions that are built into your scale,
please read the following important guidelines:
-Always be sure that the display shows `Zero` before use, if it does not then please press the ZERO key.
- The Professional Medical Hoist scale is designed to detect when a stable weight is achieved, your reading
should be taken at this point.
ATTENTION!
Tilt angle over 3° will cause false reading.
During weighing phase by means of RS dynamometer, the operator must be sure that the
patient remains still, to avoid any instruments torsion and the following uncorrect
weighing.
We recommend to not use any lift or Hoist that hanger bar do not swivel 360 degrees.
After assembly at the lifter, the dynamometer must not be rotated horizontally. Rotation is
only allowed in connection with 360 degree swivel bearings installed in the lift system.
ATTENTION!
For measuring the patient ALWAYS SAFE
The operator MUST place a pillow
under the patient raised
WEIGHING THE PATIENT MUST BE STRICTLY OBSERVED

12. CLEANING & MAINTENANCE
We would recommend using alcohol based wipes or similar when cleaning the scales. Please do not use
large amounts of water when cleaning the scales as this will cause damage to the scales electronics, you
should also refrain from using corrosive liquids or high pressure washers. Always disconnect the scales
from the mains power supply before cleaning.
The machine is sold approved with first metrological test passed (plate with green M). If required, the first
periodic test (green label) can be performed by the manufacturer. At the expiry date indicated on the green
label, the periodic test must be performed on the machine. Subsequent calibration is always necessary, if
one or more safety markings are damaged or the display shows abnormal weights. Always have maintenance
performed by qualified personnel. The WUNDER customer technical support service is at your disposal.
ATTENTION!
In some countries, calibration can be performed only by an authorised/qualified agent. Contact your dealer for
further
