2. General Safety Instructions

Duties of the owner-operator
Follow the national accident prevention regulations as well as the working, operating and safety regulations of the owner-operator.
Observe all safety regulations of the crane manufacturer. The balance may only be used for the proposed purpose. Any type of use which
is not specified in these operating instructions, will be considered as improper use. The customer is solely responsible for material damage and injury of persons resulting from an improper use, Messrs. KERN & Sohn will not be liable under any circumstance. Messrs. KERN & Sohn cannot be held liable, if the crane scales are modified or used improperly and if damage is resulting from such use.
Carry out regular maintenance and care of the crane scales, the crane and the
load suspension devices (see chapter 9).
Log the test result and keep it in the logbook.
Organizational measures
Only trained and instructed staff may operate the balance. Make sure that the operating instructions are kept nearby the operation site of the
crane scales.
Assembly, commissioning and maintenance should only be carried out by trained
specialists.
Repair of safety-relevant pieces may only be carried out by KERN or by service
partners authorized by Messrs. KERN. (competence certificate or training).
Use original spare parts only. All repairs and spare parts must be documented by the service partner (see list,
chap. 10.3).
All maintenance must be documented (see checklist chap. 9.3). Load suspending components may only be exchanged as a complete spare parts
set. The dimensions of the new components must be noted (see checklist chapter
9.3).
Ambient conditions
Never operate the crane scales in explosive environment. The serial version is
not explosion protect e d.
Operate the crane scales only under environmental conditions as specified in
these operating instructions (especially in chapter 1 „Technical data“).
Do not expose the crane scales to strong humidity. Non-per mitt e d condensation
(condensation of air humidity on the appliance) may occur if a cold appliance is taken to a considerably warmer environment. In this case, acclimatize the disconnected appliance for ca. 2 hours at room temperature.
Do not operate the crane scales in corrosive environment. Protect the crane scales against high humidity, vapours and dust.
HFB-BA-e-1212
Major display deviations (incorrect weighing results) may be experienced should
electromagnetic fields (e.g. due to mobile phones or radio equipment), static electricity accumulations or instable power supply occur. Change locat ion or remove source of interference.
Proper use
The balance you purchased is intended to determine the weighing value of material to be weighed. It is intended to be used as a “non-automatic“ balance, i.e. the material to be weighed is suspended 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 devic es
- 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.
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“ in the balance. (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.
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 meas ur i ng sy s tem is overloaded
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.).

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 (www.kern-sohn.com) with regard to the monitoring of balance test substances and the test 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.
Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage.
Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have reached the operating temperature (see warming up time chap. 1). During this warming up time the balance must be connected to the power supply (mains, accumulator or battery). The accuracy of the balance depends on the local acceleration of gravity. Strictly observe hints in chapter Adjustment. Check the original dimensions, see chap. 4.2.
Shutdown and storage
Take off the crane scales from the crane and dismantle all load attachment
devices from the crane scales.
Do not store the crane scales at open air

Safety bracket
The crane scales are a multi-purpose and cost-saving solution for overhead weighing applications such as e.g. recycling, metal processing, machine engineering, transport and logistics. With the radio remote control operation will be more comfortable yet.
