2. Safety notes
Structural changes to the scale and its components may result in a threat to life
due to falling loads.
• Repairs or structural changes to the scale and its components are not permit-
ted.
• Conversions of and repairs to the scale may only be carried out by individuals
trained and authorized by the manufacturer.
• Only original spare parts and accessories approved by the manufacturer shall
be used.
Inadequate maintenance can endanger persons due to undetected damage to
the scale.
• Inspect the scale and all associated components for damage regularly.
• Have damaged components replaced by PFREUNDT Service.
2.1 Intended use (for legal-for-trade scales)
The scale is designed for use on:
• 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 internaonal approvals available.
This type of construcon can only be used if weighing the bulk goods has been
secured so that the loose goods will not tend to sck together.
Changes to the liing lever, the liing cylinder, the switching points of the prox-
imity switches / posion sensor are not permied.
Any use other than as designated shall be deemed
incorrect.

4www.pfreundt.de
In Germany, the scale may only be used for business or ocial purposes if it has
been properly assessed and calibrated.
Observe all applicable naonal regulaons.
Calibrate the scale periodically
Scales of this type are subject to mandatory calibraon and may only be used in
compliance with the naonal statutory regulaons of the relevant country. The
company operang the scales is responsible for regular calibraon in accordance
with naonal regulaons.
Naonal use obligaons
Scales of this type may only be used in compliance with naonal restricons.
They are subject to the accuracy classes. Therefore, scales of this type may only
be used in compliance with naonal regulaons.
Requirements in Germany include:
Y(b) Accuracy Class automac 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 excavaon
> 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 Calibraon 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-
mac 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 reect price developments and published in the Federal Ga-
zee by the PTB [Naonal Metrology Instute of the Federal Republic of Germany].

2.2 FCC and IC Cercaon
This device contains licence-exempt transmier(s)/receiver(s) that comply with
Innovaon, Science and Economic Development Canada’s licence-exempt RSS(s)
and complies with part 15 of the FCC Rules.
Operaon is subject to the following two condions:
• 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 modicaons made to this equipment not expressly approved by
PFREUNDT GmbH may void the FCC authorizaon 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 protecon 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 instrucon manual, may cause harmful interference to radio communi-
caons. Operaon of this equipment in a residenal 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 potenal for human contact during normal operaon is minimized.
The highest reported SAR for body, limb-worn exposure condions are
0.371 W/kg and 0.213 W/kg respecvely.

2.3 Risks of improper use
Improper use of the scale may lead to life-threatening situaons. The scale has
not been approved for operaon 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 trac.
• 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.

Tilt seng
Weigh in the most horizontal posion possible. If the vehicle is at too much of an
incline, a warning appears in the display and weighing is no longer possible.
Weigh only in the permied 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.
3. Operang condions for correct weighing
4.1 Switching on the scale
1. Hold the On/O buon down for
about 2 seconds.
2. The weighing unit acvates.
3. Aer the start-up process, the weighing

4.3 Menu opons
Acvate the "Seng-to-zero" funcon
Aer pressing the key, you need to move the empty loading
bucket through the weighing posion. The zeroing takes place
automacally.
If the empty weight is within the seng-to-zero range the
displayed gross weight is adopted as the new zero point of the
scale.
If the empty weight is outside the seng-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.
Aer emptying the loading bucket, cancellaon is no longer
possible.
Conrm weight
If "automac cancellaon" is acve, you need to conrm every
weight for the total. Otherwise any weighing cancels automa-
cally when the loading bucket is emped.
Backweighing
If you only want to weigh a parally loading bucket (e.g. to
avoid overloading the vehicle), you must enable backweighing.
Aer emptying the loading bucket, backweighing is no longer
possible.

5. Zeroing the scale
5.1 Zeroing the scale (dynamic)
1. > Open the menu and acvate the "Seng-to-zero" funcon.
2. The prompt for zeroing the scale appears.
This does not delete the current total.
3. Lower the liing arm and raise the empty loading bucket completely (for forklis,
posion the mast vercally).
4. Move the liing arm through the weighing posion from below.
5. The zeroing takes place automacally.
5.2 Zeroing the scale (stac)
You can perform a stac zeroing if necessary, depending on the conguraon.
Depending on the seng, the stac zeroing can be done aer the liing move-
ment or aer lowering the liing arm.
1. > Open the menu and select the funcon "Seng-to-zero".
2. The prompt for zeroing the scale appears.
3. This does not delete the current total.
4. Pull the empty loading bucket in completely.
5. Depending on the conguraon, move the liing arm from below or from above
to any posion within the weighing area and stop briey.
6. The zeroing takes place automacally.

12 www.pfreundt.de
5.3 Forced zeroing and warm-up strokes on demand
There are several situaons in which compulsory zeroing may be required:
• If the current oil temperature deviates by 10°C from the last measured value.
The oil temperature is measured and stored at each zeroing
• At the latest 30 minutes after the last zeroing.
Depending on the conguraon, you will be prompted to zero the scale again.
Warm-up strokes
Depending on the conguraon, you will also be asked to perform some warm-up
strokes with the bucket before zeroing. This is to ensure an opmum operang
temperature (oil temperature) in the hydraulics.
If the corresponding warning appears in the display, proceed as follows:
1. Carry out the current weighing
if there is sll material in the
bucket.
2. Lower the liing arm and raise
the empty loading bucket com-
pletely.
3. Move the liing arm through the
weighing posion from below
several mes (e.g. 10 mes). 10 x
4. Connue with (depending on the
