2. General Safety Instructions
2.1 Duties of the owner-operator
Follow national accident prevention regulations and all operator health and
safety at work and operating regulations.
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 suspended balance is
modified or used improperly and if damage is resulting from such use.
Carry out service and repair to suspended balance (see chap. 9.3), crane and
lifting tackle at regular intervals.
Log the test result and keep it in the logbook.
2.2 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
suspended balance.
Assembly, commissioning and maintenance should only be carried out by trained
specialists.
Weight-bearing components must not be replaced.
2.3 Environmental conditions
Never operate suspended balance in spaces exposed to explosion hazards. The
serial version is not explosion protected.
Operate the suspended balance only under environmental conditions as specified
in these operating instructions (especially in chapter 1 „Technical data“).
Do not expose the suspended balance to strong humidity. Non-permitted
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 use suspended balance in environments exposed to corrosion hazards.
Protect the suspended balance against high humidity, vapours and dust.
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 location or
remove source of interference.
