2. General safety instructions
User obligations
It is necessary to follow the national OH&S regulations as well as operating, user and
safety instructions in force in the user’s location.
Follow all the safety instructions of the crane (overhead crane) manufacturer.
Always use the scale in line with its intended use. Every use type not listed in this
user manual is deemed to be the use other than the intended one. The owner,
and not KERN & Sohn, shall be the only party liable for any property damage and
injuries resulting from such non-intended use.
KERN & Sohn shall not be held liable for any unauthorised modifications or non-
intended use of the crane scale and any resulting damage and losses.
The crane scale, the crane (overhead crane) and the hoisting equipment shall be
maintained periodically and kept in a good technical condition (see chapter 8).
The inspection result should be recorded and kept in the logbook.
Organisational measures
The device should be operated solely by trained and instructed people.
Ensure constant access to the user manual in the crane scale operation location.
The installation, startup and maintenance should always be carried out by the
trained specialists.
Always use the original spare parts.
All the repairs must be carried out solely by trained specialists. Repairs and spare
parts must be documented. (See the “Spare parts and repairs of components
important for safety” list).
All the effects should be documented (see the “Periodic maintenance” checklist in
chapter 8.3).
The load-bearing structural components must be replaced as a complete spare
part assembly. The dimensions of new structural components must be recorded
(see the “Periodic maintenance” checklist in chapter 8.3).

9 HCD-BA-e-2214
Ambient conditions
Never operate the crane scale in explosive atmospheres. The standard version is
not explosion-proof.
The crane scale should always be used in ambient conditions described in this
user manual (in particular in chapter 1 “Technical Specification”).
Do not expose the crane scale to heavy moisture. Any forbidden condensation of
the air moisture on the device may occur when a cold device is placed in a much
hotter environment. In such circumstances, leave the device not connected to the
mains for 2 hours to adapt to the ambient temperature.
Do not use the crane scale in any corrosive environment.
Protect the crane scale from high humidity of air, vapours, liquids and dust.
Avoid extreme temperatures and temperature fluctuations resulting e.g. from
direct solar radiation.
If there are any electromagnetic fields (caused e.g. by mobile phones or radio
devices), static discharge and unstable power supply, high readout deviations
(erroneous weighing results) may occur. Relocate the unit or remove the source
of interference.
Intended use
The scale you bought is intended for weighing the weighed material. It should be
deemed to be a “non-automatic one”, where the material to be weighed should be
manuallyhung on the crane (overhead crane) hook vertically, carefullyand “smoothly”.
The weight can be read after it has stabilized.
The crane scale should always be used to lift and weigh loads which move freely.
Any non-intended use brings about the injury hazard. It is prohibited e.g. to:
- Exceed the permissible rated load of the crane (overhead crane), crane
scale or any components used to hoist the load;
- Carry people;
- Pull the loads diagonally;
- Remove the loads by force, pull them out or drag them.
It is prohibited to modify or alter the crane scale or the crane (overhead crane).

HCD-BA-e-2214 10
Intended use of the rotary hook
The rotary hook enables to hang the weighed material easily and comfortably.
The hook rotation is not active once the load is suspended. The load suspended
on the crane scale must not rotate. The rotation must be effected using the rotary
hook. Generally speaking, the loaded crane scale must not rotate. (Static load
suspension and removal).
Non-intended use
Do not use the scale for dynamic weighing. If the amount of the weighed material is
reduced or increased significantly, the scale’s “stabilizing and compensating”
mechanism can result in displaying erroneous weighing results! (Example: slow
outflow of the liquid from the container suspended on the scale.) Do not subject the
scale to long-term load. It maydamage the weighing mechanism andalso components
important for safety reasons.
The scale should always be operated in line with the provided guidelines. Other
operation ranges / areas require a written consent of KERN.
Guarantee
The warranty expires:
if you fail to follow our guidelines included in the user manual;
if you fail to use the device in line with the intended use;
if you introduce any modifications or open the device;
if the device gets damaged mechanically or damaged by the utilities, liquids;
if there is any ordinary wear and tear;
if the device is not set correctly or the electrical system is not as required;
if the weighing mechanism gets overloaded.
Operation in line with the safety rules
Do not stay under suspended loads.
Always position the crane (overhead crane) to ensure the load is lifted upright.
When operating the crane (overhead crane) and crane scale, always use
personal protection equipment (hard hat, protective footwear etc.).
Testing equipment supervision
Within the quality assurance system, you must check the technical measurement
properties of the scale and possibly of the available reference weight regularly. To that
aim, the responsible user should define a relevant cycle, as well as the type and scope
of such an inspection. The information on the supervision of the testing equipment, i.e.
scales, and the required reference weights, can be found on the home page of KERN
(www.kern-sohn.com). The reference weights and scales can be calibrated fast and at
a lowcost in the KERN calibration laboratory (against the national reference) approved
by DKD (Deutsche Kalibrierdienst).

11 HCD-BA-e-2214
Checking during reception
Immediately after you have received the shipment, please check if it is free from any
visible damage. The same applies for the unpacked device.
First start
To get accurate weighing results using electronic scales, ensure the scales achieves
the appropriate operating temperature (see “Heating time”, chapter 1).
During heating, the scale must be connected to the power source (rechargeable
battery or battery).
The scale accuracy depends on the local standard gravity.
Always follow the guidelines in the “Adjustment” chapter.
For the original dimension check, see chapter 4.2.
Decommissioning and storage
Remove the crane scale from the crane (overhead crane) and remove any
hoisting equipment.
Do not store the crane scale outdoors.

HCD-BA-e-2214 20
5.2 Crane scale loading
To achieve correct weighing results, follow the following instructions, see the figures
on the following page:
Always use the components for load hoisting which ensure one-point free scale
suspension.
Do not use too large hoisting equipment which does not ensure one-point
suspension.
Do not use multiple slings.
Do not pull and move the load with the loaded scale.
Do not pull the hook horizontally.
Scale loading
1. Place the crane scale hook above the load.
2. Lower the crane scale to enable load suspension on the scale hook. Once you
reach the suitable height, reduce the speed.
3. Hang the load on the hook. Ensure that the safety catch is closed. When installing
the load using rope slings, ensure that the slings are well positioned in the scale
hook saddle.
4. Raise the load slowly.
When installing the load usingrope slings, ensure the load is balanced and the rope
slings are positioned correctly.
