• Wheel loaders with a loading bucket *
• Forklift truck with lifting forks or loading buckets as load carrier *
• Telescopic handlers with lifting forks or a loading bucket *
* Approved for Europe, other internaonal approvals available.
This type of construcon can only be used if weighing the bulk goods has been
secured so that the loose goods will not tend to sck together.
Changes to the liing lever, the liing cylinder, the switching points of the prox-
imity switches / posion sensor are not permied.
Any use other than as designated shall be deemed
incorrect.

company operang the scales is responsible for regular calibraon in accordance
with naonal regulaons.
Naonal use obligaons
Scales of this type may only be used in compliance with naonal restricons.
They are subject to the accuracy classes. Therefore, scales of this type may only
be used in compliance with naonal regulaons.
Requirements in Germany include:
Y(b) Accuracy Class automac scales may be used for the following categories of
materials.
• Bulk goods and mass raw materials, such as:
> Gravel, sand, natural stone, foundry slag aggregates
> Building material such as ready-mix concrete, mortar, tar coated gravel and
similar building materials
> Building rubble and building rubble to be recycled
> Earth and oor excavaon
> Ceramic raw materials and industrial minerals
> Road salt
> Compost
• Household waste for disposal
Other goods with a per ton value not exceeding four mes the amount of the services
according to the MessEV [Measurement and Calibraon Ordinance] or with per ton dis-
posal costs not exceeding four mes the amount of the services according to §5 (1) No. 12
of the MessEV, may also be weighed using Accuracy Class IIII scales or using auto-
mac scales of the corresponding accuracy class (such as (Y(b)).
The fee for the services pursuant to §5 (1), No. 12 of the MessEV will be adjusted
every three years to reect price developments and published in the Federal Ga-

2.2 FCC and IC Cercaon
This device contains licence-exempt transmier(s)/receiver(s) that comply with
Innovaon, Science and Economic Development Canada’s licence-exempt RSS(s)
and complies with part 15 of the FCC Rules.
Operaon is subject to the following two condions:
• This device may not cause harmful interference.
• This device must accept any interference received, including interference that
may cause undesired operation of the device.
Changes or modicaons made to this equipment not expressly approved by
PFREUNDT GmbH may void the FCC authorizaon to operate this equipment.
NOTE:
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protecon against harmful interference when the equipment
is operated in a commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used in accordance
with the instrucon manual, may cause harmful interference to radio communi-
caons. Operaon of this equipment in a residenal area is likely to cause harm-
ful interference in which case the user will be required to correct the interference
at his own expense.
The radiated output power of the device is far below the FCC and ISED radio fre-
quency exposure limits. Nevertheless, the device should be used in such a man-
ner that the potenal for human contact during normal operaon is minimized.
The highest reported SAR for body, limb-worn exposure condions are
0.371 W/kg and 0.213 W/kg respecvely.

2.3 Risks of improper use
Improper use of the scale may lead to life-threatening situaons. The scale has
not been approved for operaon in:
• Potentially explosive environments
• Aggressive environments (e.g. in rooms with acid, etching or galvanizing
baths)
• Environments prone to stray currents or heat (e.g. due to welding)
Overloading transport vehicles is life-threatening. Overloaded transport vehi-
cles are unsafe in trac.
• Obtain information about permissible loading of such vehicles and comply
strictly with such limits.
• Avoid improper weighing by, for example, ensuring the correct position of the
vehicle during weighing.

incline, a warning appears in the display and weighing is no longer possible.
Weigh only in the permied temperature range:
• Only use the scale in the permitted temperature range.
• When using external components (printer, etc.), observe the temperatures
given in their specific data sheets.

4.3 Menu opons
Acvate the "Seng-to-zero" funcon
Aer pressing the key, you need to move the empty loading
bucket through the weighing posion. The zeroing takes place
automacally.
If the empty weight is within the seng-to-zero range the
displayed gross weight is adopted as the new zero point of the
scale.
If the empty weight is outside the seng-to-zero range a
warning displays.
Cancel last weighing
If necessary, you can cancel the last weighing. The weight of
the last weighing is not added to the total.
Aer emptying the loading bucket, cancellaon is no longer
possible.
Conrm weight
If "automac cancellaon" is acve, you need to conrm every
weight for the total. Otherwise any weighing cancels automa-
cally when the loading bucket is emped.
Backweighing
If you only want to weigh a parally loading bucket (e.g. to
avoid overloading the vehicle), you must enable backweighing.
Aer emptying the loading bucket, backweighing is no longer
possible.
