on the crane hook only vertically, manually, carefully and without jerks. As soon as a stable
weighing value is reached the weighing value can be read.
Use the crane scales only for lifting and weighing of freely movable loads.
Danger of injury due to improper use. Not allowed are e.g.:
Exceeding the allowed nominal load of crane, crane scales or any type of load
attachment devices
Conveying persons,
Pulling loads over an inclined surface,
Tearing-off, pulling or towing loads.
Modifications or reconstructions of the crane scales or of the crane are not allowed.
3.4 Improper Use
Do not use balance for dynamic weighing. In the event that small quantities are removed or added
to the material to be weighed, incorrect weighing results can be displayed due to the "stability
compensation". (Example: Slowly draining fluids from a container suspended on the balance.) Do
not leave permanent load suspended on the balance. This may damage the measuring system as
well as safety-relevant parts.
The balance may only be used according to the described conditions. Other areas of use must
be released by KERN in writing.
3.5 Warranty
Warranty claims shall be voided in case
Our conditions in the operation manual are ignored
The appliance is used outside the described uses
The appliance is modified or opened
Mechanical damage and damage caused by media, liquids,
Natural wear and tear
The appliance is improperly set up or incorrectly electrically connected
The measuring system is overloaded
3.6 Safe working
Do not stand underneath suspended loads!
Position the crane in a way that the load is lifted vertically.
When working with the crane and crane scales wear personal safety equipment (helmet,
safety shoes etc.).
3.7 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the balance and, if
applicable, the testing weight, must be checked regularly. The responsible user must define a
suitable interval as well as type and scope of this test. Information is available on KERN's home
page

weights required for this. In KERN's accredited DKD calibration laboratory test weights and
balances may be calibrated (return to the national standard) fast and at moderate cost
