Safety
2.5 General safety regulations
Fitting, retrofitting, maintenance and inspection work
may be carried out on non-operational equipment only
and by trained personnel only.
For reasons of safety, unauthorised modifications and
changes to the crane scales are not permitted.
Operating personnel must always ensure that the maxi-
mum load is never exceeded.
Personnel must not stand underneath a suspended load
as this could come loose and fall.
Personnel must not ride on or be lifted by the equip-
ment. Access to lifting equipment is not permitted.
2.6 Safety information for operating personnel
No operational mode which could compromise the safety
of the crane scales may be undertaken
It is the responsibility of the operator to ensure that no
unauthorised personnel work on the crane scales (e.g.
also by working on equipment in a manner contrary to
authorised use).
It is the responsibility of the operator to check the crane
scales at least once before use (once a day) for exter-
nally apparent damage or defects and to report any
changes (including to the way the machine is operating)
which are likely to compromise safety.
It is the responsibility of the operator to ensure that the
crane scales is operated only in perfect order and con-di-
tion.
It is the responsibility of the operator to insist that oper-
ating personnel must wear protective clothing wherever
necessary.
Under no circumstances must safety devices be re-mo-
ved or put of operation (potential risk of serious crushing,
danger to life).
If it is necessary to remove any safety devices for fitting,
repair or maintenance work, they must be re-installed im-
mediately after maintenance or repair is complete.
2.7 Tests
Lifting equipment is a testable suspension. It is therefore
the Guidelines for Hoists issued by the German Employ-
ers' Liability Insurance Association, the Central Agency
for Accident Prevention, the Test Guidelines and the test
regulations according to DIN 685 Part 5 Nov. 1981, UVV,
DGUV Regulation 54 and UVV, DGUV Regulation 54
and UVV, DGUV Regulation 52 and DIN EN 818-7 of
September 2002.
The entry in the crane test book must be made via re-
pairs and tests carried out.
2.8 Basic security instructions
For good performance and accurate measurement, the
points below should always be followed:
1. DO NOT overload the scale. Overloading will damage
the load cell and void the warranty.
2. Do not attach a permanent load. This can damage the
measuring mechanism as well as safety-relevant
parts.
3. It is essential to prevent overloading of the balance
above the specified maximum load (Max), less any
Tara load that may already be present. This could da-
mage the scale (risk of breakage!).
4. Check chain and hook before each use. Check the
clamp, pins and screws regularly.
5. Check the battery constantly. If the scale is no longer
supplied with power, charge the battery with the
appropriate charger or replace it with a full battery.
6. Turn the load, if necessary, instead of the balance.
7. NEVER use the scale during thunderstorms (lightning,
rain, etc.).
8. Store the device in a dry and well-ventilated area. The
crane scale must NOT be stored outdoors.
9. NEVER attempt to repair the balance yourself.
10. Only load the balance in the vertical direction of pull.
11. Always avoid vibrations and horizontal forces.
12. Avoid sudden, sudden acceleration or deceleration
of the load (risk of breakage!).
HINWEIS!
All local regulations (the latest valid version) which
apply in the country where the device is used must be
complied with
In Germany, currently
DGUV Regulation 1 - The principles of prevention
DGUV Regulation 3 - Electrical systems and means
of production

Intended use
KW-Series | Version 1.03 7
3 Intended use
The Crane scale is used solely to weigh free moving
loads on the crane. The Crane scale may only be opera-
ted by persons trained on the machine.
Proper use also includes compliance with all information
in this manual. Any use beyond the intended use or
otherwise is considered misuse.
For structural and technical changes to the Crane scale,
the company Stürmer Maschinen GmbH assumes no lia-
bility.
Claims of any kind due to damage due to improper use
are excluded.
3.1 Foreseeable misuse
If the intended use is observed, any reasonably foresee-
able misuse which could lead to hazardous situations
with personal damage is impossible with the crane
scales.
3.2 Residual risks
Even if all safety regulations are observed a residual risk
in the operation of the crane scales will remain, as de-
scribed below.
All persons working with the crane scales must be aware
of these residual risks and follow the instructions which
prevent any accidents or damage caused by these resi-
dual risks.
- Risk of crushing of upper and lower limbs while
equipment is operating.
- During set-up and adjustment works it may be-
come necessary to remove safety devices in-stal-
led by the customer. This causes different re-sidual
risks and hazard potentials each operator must be
aware of.

8.3 Test run
Before operating under load, perform a test run with all
functions tested without load.
8.4 Lift the load upwards
Step 1: Attach the Crane scale to a suitable fixture.
Step 2: Impact the load hook of the Crane scale on a
suitable attachment point of the load and check
that the safety of the hook is closed.
NOTE!
The "automatic shutdown" can be set to the following
values: 0 (never), 5 min, 15 min, 30 min, 60 min.
ATTENTION!
The Auto Off feature maximizes battery life. It starts
the countdown timer if no operation is performed or
the load is stable. When a key is pressed or the load
moves, the countdown timer is restarted.
NOTE!
The energy-saving mode can be set to the following
values: 0 (never), 5 sec, 15 sec, 30 sec, 60 sec.
ATENTION!
Battery life is maximized by the balance automati-
cally switching to energy-saving mode when no ope-
ration is performed or the load is stable. The balance
is working in energy-saving mode. Each key press or
load movement activates the balance from the
energy saving mode.
ATTENTION!
The "display" function allows you to choose between
different qualities of the display presentation as long
as the scale is in motion. The lower the value for the
display level, the faster a weight display will appear,
but the longer it takes for the displayed value to be
stable.
NOTE!
The display levels for the display can be set to the
following values: 0 (off), 1 (very low), 2 (low), 3 (nor-
mal), 4 (high), 5 (very high).
ATTENTION!
- Make sure that there are no people nearby when lif-
ting the crane scale.
- Make sure that the lifting distance of the load is free of
obstacles.
- Avoid putting the load into commuting.
NOTE!
- Check the center of gravity of the attachment point to
prevent movement and slippage of the load.
- Slings (eyelet, chain, etc.) must lie loosely in the hook
base.
- Hook tip may not be loaded.
- Close the fuses.

9 Care, Maintenance and Repair
9.1 Care by cleaning
The Crane scale must always be kept in a clean condition.
All plastic and lacquered surfaces should be cleaned
using a soft, damp cloth and a neutral cleaning agent.
Remove any excess lubricant or leaked oil using a dry,
lint-free cloth.
9.2 Battery maintenance
The scale is powered by a rechargeable 6V lead-acid
battery. To maximize battery life, please note the follo-
wing points:
1. The battery is permanently attached to the battery
compartment. To remove the battery, remove two
screws on the access door, pull the battery straight
out, and disconnect the battery cable from the scale.
2. Depending on the setting of the LED brightness or the
LCD backlight, the working time of the battery varies
from 80 to 200 hours.
3. To increase battery life, enable the "Auto Power
Down" function and the "Downtime" mode, dim the
LED brightness, or turn off the LCD backlight.
4. The charging time for a fully discharged battery is
about 8 hours.
5. For maximum life, the battery should be stored bet-
ween -20 ° C (-4 ° F) and + 50 ° C (122 ° F). The bat-
tery should be charged every three months.
6. When charging the battery, the green charging indica-
tor light comes on. If the lamp is red, charging is com-
plete.
9.3 Maintenance and Repair
If the Crane scale does not work properly, contact a de-
aler or our customer service. The contact details can be
found in chapter 1.2 Customer Service.
All protective and safety equipment must be reinstalled
immediately after repair and maintenance work has been
completed.
Maintenance plan
If increased wear is detected during regular checks,
shorten the required maintenance intervals according to
the actual signs of wear. If you have questions about
maintenance work and intervals, contact the manufactu-
rer. The contact details can be found on page 3 in chap-
ter 1.2 Customer Service.
Step 2: Check the crane scale for external damage be-
fore each use.
Step 3: Make sure that all safety instructions on the
crane scale are clearly legible.
NOTE!
- The operator must have sufficient stability and free-
dom of movement.
- Load and suspension hooks deform when overloaded,
there is no brittle breakage.
CAUTION!
Crushing!
When the load is released, it can cause bruising of the
upper and lower limbs.
- Do not hold the upper and lower limbs between the
load and the ground when setting down the load.
Wear safety gloves!
NOTE!
Never use harsh cleaning agents for any cleaning
work. This can lead to damage or destruction of the
device.
