2 Basic instructions about weighing system
2.1 Proper use
The weighing system 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 manually and carefully placed in the centre of the
loading fork. As soon as a stable weighing value is reached the weighing value can
be read.
VFS-BA-e-1111
5
2.2 Improper Use
Do not use the weighing system 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 weighing system.
(Example: Slowly draining fluids from a container on the weighing system.)
Do not leave permanent load on the loading fork. This may damage the measuring
system.
Impacts and overloading exceeding the stated maximum load (max) of the weighing
system, minus a possibly existing tare load, must be strictly avoided. The weighing
system could be damaged.
Never operate the weighing system in an explosive environment. The serial version is
not explosion protected.
Changes to the weighing system's design are not permitted. This may lead to
incorrect weighing results, safety-related faults and destruction of the weighing
system.
The weighing system unit may only be operated in accordance with the described
default settings. Other areas of use must be released by KERN in writing.
2.3 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 measuring system is overloaded
2.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the
weighing system 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.

3 Basic safety notes about weighing system
3.1 Pay attention to the instructions in the Operation Manual
Carefully read this operation manual before setup and
commissioning, even if you are already familiar with KERN
balances.
3.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
4 Transport and storage
4.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
4.2 Packaging / return transport
• Keep all parts of the original packaging for a possibly
required return.
• Only use original packaging for returning.
• Prior to dispatch disconnect all cables and remove
loose/mobile parts.
• Reattach possibly supplied transport securing devices.
• Secure all parts such as the glass wind screen, the weighing
platform, power unit etc. against shifting and damage.

5 Unpacking, Setup and Commissioning
5.1 Assembly of the pallet truck scale
5.1.1 Drawbar
The drawbar is delivered separated from the hydraulic lifting device. Prior to
commissioning the two components must be connected to each other. Details see
below.
Ö Turn out screw for hydraulic
adjustment
Ö Pass the draw chain of the drawbar through the opening and after that through
the bolt in the pallet truck scale
8
VFS-BA-e-1111
Ö Insert rod at the lower end of the
draw chain at the oblong hole of
the hydraulic lever till to the
stopper
Ö Fix the grab handle using 3
screws
Ö To start-up the lifting mechanism

5.2 Proper use of the lifting device
Ö Lower the loading fork
Ö Move the load
Ö Lift the loading fork
5.3 Installation site, location of use of the weighing system
The weighing system is designed to achieve reliable weighing results under normal
conditions of use.
You will work accurately and fast, if you select the right location for your weighing
system.
Therefore, observe the following for the installation site:
• The load must be lifted clear of the display unit’s case and other pallets.
Incorrect lifting of a load
Correct lifting of a load
• The accuracy of the weighing system is falling by approximately 0.1 % per degree
if there is a slant of more than 2°. Holes and unevenness, too, have this effect. A
smooth floor is ideal.
• Optimum accuracy in weighing results is achieved if the load centre is between
the forks. The forks are easily bent and twisted when the load is off-centre. This
may result in diminished accuracy.
In verifiable models off-centre loads, or slants affecting accuracy, activate the
inclination switch which in turn disconnects the display.
12
VFS-BA-e-1111
Load
Pallet
Non-optimal positioning of load
Optimal positioning of load
• Temperature range: The maximum deviation for 0.1% of the weighed load is
between -10 and +40°C. Outside this temperature range deviations of up to 0.3%
may occur.
• Avoid jarring during weighing
• Protect the weighing system against high humidity, vapours and dust
• Do not expose the device to extreme dampness for longer periods of time. 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.
• 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.

To economize the rechargeable battery, the weighing system switches off
automatically x minutes after a finished weighing as preset in menu item „F3 oFF“
(chap. 9.2).
If the capacity of the rechargeable battery is soon exhausted, in the display appears
the battery symbol . The weighing system remains ready for operation for an
other 30 minutes, after that it switches off automatically to economize the
rechargeable battery.
To load the rechargeable battery, connect the delivered power pack, the weighing
system needs not to be switched on. After 15 hours the rechargeable battery is
completely loaded.
Left next to the display window there is a LED , which illuminates during the
loading process.
5.6 Commissioning
Prior to starting-up the weighing system, load the rechargeable battery completely.
To activate the weighing system, press the key.
The operating temperature for the electronic system and the weighing cells will have
been reached after three to five minutes. Prior to this, deviations of c. 0.3% are
possible.
Loads should not be lifted before this zero adjust is complete.

6 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each balance must be coordinated - in compliance with the underlying physical
weighing principle - to the existing acceleration due to gravity at its place of
location (only if the balance has not already been adjusted to the location in the
factory). This adjustment process must be carried out for the first commissioning,
after each change of location as well as in case of fluctuating environment
temperature. To receive accurate measuring values it is also recommended to
adjust the balance periodically in weighing operation.
Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization. Ensure that the system is not loaded. The system should
be lifted by approximately 2 lifting index markings and stand absolutely free.

10 Service, maintenance, disposal
10.1 Clean
Please do not use aggressive cleaning agents (solvents or similar agents), but a cloth
dampened with mild soap suds. Ensure that no liquid penetrates into the device and
wipe with a dry soft cloth.
10.2 Service, maintenance
The same maintenance guidelines apply to the chassis of the mobile weighing
system as those for simple manual pallet trucks. Experience has taught us that the
integrated weighing system continues to function even if the chassis was damaged
by overloading.
General rules:
Ö As the steering wheels are mounted at the front, it is better to pull rather than
push the manual pallet truck.
Ö If the lifting device is not used, the manual lever should be left in centre position.
This prolongs the life span of the seals.
Ö To prevent damages to the electronic system and weighing cells it is necessary
that welding work on the entire weighing system is carried out exclusively by
technical specialists.
Ö The bearings of the wheels (with the exception of polyurethane) as well as the
joints in the load roller section should be regularly cleaned and greased.
10.3 Disposal
Disposal of packaging and appliance must be carried out by operator according to
