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.
• Use original spare parts only.
• All repair work must be carried out by trained specialists. Repairs and spare parts must be documented. (see list ,spare parts and repair of safety-relevant parts)
• All maintenance must be documented (see checklist „Regular maintenance" chap. 9.3).
• Load suspending components may only be exchanged as a complete spare parts set. The dimensions of the new components must be recorded (see checklist „Regular maintenance" chapter 9.3).

Ambient conditions

• Never operate the crane scales in explosive environment. The serial version is not explosion protected.
• 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-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 operate the crane scales in corrosive environment.
• Protect the crane scales against high humidity, vapours and dust.
• Avoid extreme heat as well as temperature fluctuations e.g. caused by direct sun light..
• 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.

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 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.

Intended use of rotating load hooks

• The rotatable load hook has been provided for a simple and comfortable hooking of the weighed material.
• The rotating function of the load hook under load is out of function. The load on the crane scales must not be swiveled. Any turning movement must be done ba a rotatable crane hook.. A loaded crane scales generally must not be rotated. (static loading and unloading of a load).

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 use
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

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

3. The crane scales at a glance

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.

5. Operation

5.1 Safety instructions

DANGER Risk of injury due to falling loads!

→ Always work with particular care according to the general rules for crane operation. → Check all parts (hook, eyelet, rings, rope slings, cables, chains etc.) for excessive wear or damage → If faults can be seen on the safety bracket of the hook or if it is missing completely, the scales must not be used. → Work only with appropriate speed. → Always avoid vibrations and horizontal forces. Avoid any kind of shock, torsion and oscillating (e.g. caused by inclined suspending). → Do not use the crane scales for transport of loads → Do not stand or go under suspended loads. → Do not use on building sites. → Suspended loads have to be observed constantly. → Do not exceed the nominal load of crane, crane scales or any kind of load attachment devices at the crane scales. → For weighing dangerous goods (e.g molten masses, radioactive materials) the “Dangerous Goods Regulations” are to be regarded!

5.2 Loading the crane scales

For good weighing results observe the following, illustrations see next page:

Only use load attachment devices which guarantee a one-spot suspension and where the scales can be suspended freely.
Do not use too large load attachment devices which do not guarantee any one-spot suspension.
Do not use multiple suspensions.
Do not pull or push the load or the loaded balance.
Do not pull the hook horizontally.

Loading the balance

1. Position the hook of the crane scales over the load.
2. Move downwards the crane scales until the load can be suspended on the hook of the balance. Reduce the speed when the respective height is going to be reached.
3. Suspend the load on the hook. Ensure that the safety bracket is closed. If the load is fixed by slings, ensure that the slings rest completely on the saddle of the balance hook.
4. Lift-off the load slowly.

When the load is fixed by slings, ensure that the load is well balanced on both sides and that the slings are correctly positioned
