2.9 Fire hazards
In particular the extraction of wood dust can develop
into, during the vacuuming process or once the device
is switched off, a combustible dust and air mixture. This
mixture can develop into a very serious fire.
To fight this fire hazard, the dust extractor has been
equipped with an automatic spark extinguisher.
Simultaneously, the extraction fan is switched off and the
compressed air supply to clean the filter is shut off.
• The dust extraction hoses must be electrically conduc-
tive and grounded to prevent electrostatic
build up.
• The vacuum hoses/pipes must be flameproof.
• Earth vacuum hose/pipes against any static electrici-
ty that may accumulate.
• All electrical connections must be installed correctly
by a qualified person.
• Electricity suppiy only in authorized field of ± 10% of
network.
• Only vacuum sawdust and woodshavings.
• Do not vacuum spark-generating objects (e.g. nails,
screws etc.).
• Do not vacuum any inflammable waste.
(e.g. cigarette ends, flying sparks, etc.)
Warning! Danger of fire!
Incorrect installation and usage could result in a fire.
Safety
Attention! Safety regulations (Check every six months)
Check the function; the safety cover have to fall back in place after having been lifted up.

2.12 Procedure in case of fire (Emergencies)
Fig. 2-2: Procedure in case of fire
Note:
The explosion pressure proofness is 200 mbar.
2.13 Explosion pressure proofness
The RL 250 / RL300 / RL 350 clean air devices were
tested for explosion pressure proofness by the FSA GmbH
test centre.
The maximum explosion excess pressure, up to which the
dust extractor still withstood any form of damage, was
used as a proof pressure value, as detailed in the VDI
2263 Guidelines, Part 3.
Afterwards, to test the explosion pressure proofness, a
minimum of 1.1 x the proof pressure has to be attained
safely. Deformations are tolerated.
The dust extractor is tested for explosion pressure proof-
ness with an explosion pressure of 200 mbar (0.2 bar)
and therefore, can be set up in a working environment if
the necessary requirements are fulfilled.
Safety
Warning! In case of fire don´t clean the filter!
Attention! When moving the chip container, flash fire can occur!
Procedure in case of fire (Emergencies)
1. Pull the lever forwards

3 Declaration of Conformity
This EC Declaration of Conformity is valid only if the CE label has been affixed to the machine.
Modifying or altering the machine without the express written agreement of the manufacturer shall render the war-
ranty null and void.
The signatory of this statement is the appointed agent for
the compilation of the technical information
Johann Felder, Managing Director FELDER KG
KR-FELDER-STR.1 • A-6060 Hall in Tirol
We hereby declare that the machine indicated below, which corresponds to the design and construction of the model
we placed on the market, conforms with the health and safety requirements as stated by the EC.
The compact dust extractor was built according to the inspection standards of the GS-HO-07 certificate (from january
2010) and was inspected according to these inspection standards by the German wood institute for statutory accident
insurance and prevention (Holz-Berufsgenossenschaft), Vollmoellerstrasse 11, 70563 Stuttgart, Germany.
The dust extractor is thus appropriate to extract and to separate dry (wood moisture < 30%) wood dust and shavings,
whereby the residual dust contents level of 3 “H3”, 0.1 mg/m³ will be adhered to.
Explanation to guideline ATEX 2014/34/EU:
On the basis of safety this machine is NOT DESIGNED and should not be used in explosion-proof areas.
There will be combustible dusts inside the dirty gas area of the dust extractor.
Due to the ignition sources-free construction the danger of explosion will be prevented.
The limited geometrical design will avoid the remaining risk of aspirated sparks.
The machine casings of RL 250, RL 300 and RL 350 are additionally designed in pressure proof quality.

Specifications
The specified values are emission values and therefore
do not represent safe workplace values.
Even though a relationship exists between particle emis-
sion and noise emission levels, an inference cannot be
made about whether additional safety measures need to
be implemented. Factors which can significantly affect
the emission level that presently exists at the workplace
include duration of the effect, characteristics of the work-
space, and other ambient influences.
The permissible workplace values may also differ from
country to country. Nevertheless, this information is provi-
ded to help the operator better assess hazards and risks.
Depending on the location of the machine and other
specific conditions, the actual noise emission values may
deviate significantly from the specified values.
Note: The measurement results are in accordence to prEN 16770
Measured by nominal volume flow in an open sound field., without transport of the chippings

5 Transport, packaging and storage
5.1 Safety instructions
Warning! Risk of injury!
There is a risk of injury as a result of falling parts while transporting, loading or unloading the machine.
Attention! Risk of material damage!
The machine can be damaged or destroyed if it is subjected to
improper handling during transport.
For this reason the following safety instructions must be
observed:
• Never lift loads over a person.
• Always move the machine with the utmost care and
caution.
• Only use suitable lifting accessories and hoisting
devices that have a sufficient load-carrying capacity.
• Never lift the machine by its protruding parts.
• Consider the machine‘s centre of gravity when trans-
porting it (minimise the risk of it tipping over).
• Take measures to prevent the machine from slipping
sideways.
• Ropes, belts or other hoisting devices must be
equipped with safety hooks.
• Do not use torn or worn ropes.
• Do not use knotted ropes or belts.
• Ensure that ropes and belts do not lie against sharp
edges.
• Transport the machine as carefully as possible in
order to prevent damage.
• Avoid subjecting the machine to shocks.
• When transporting the machine overseas, ensure that
the packaging is airtight and that a desiccant is
added to protect the metal parts against corrosion.
5.2 Transport
Attention! Risk of material damage! The machine must be kept weatherproof while in transport.
5.3 Transport inspection
Upon arrival, inspect the shipment to ensure that it is
complete and has not suffered any damage. If any trans-
port damage is visible, do not accept the
delivery or only accept it with reservation. Record the
scope of the damage on the transport documents/
delivery note.
Initiate the complaint process. For all defects that are not
discovered upon delivery, be sure to report them as soon
as they are recognised as damage claims must be filed
within a certain period, as granted by law.

5.4 Packaging
Note: Help preserve the environment!
Packaging materials are valuable raw materials and in many cases they can be used again or
expediently reprocessed or recycled.
Note:
Keep items sealed in their packaging until they are
assembled/installed and be sure to observe the stacking and storage symbols on the outside of the packa-
ging.
Attention! Dispose of the packaging materials in an environmentally friendly way and always in
accordance with local waste disposal regulations. If applicable, contract a recycling firm to dispose of the
packaging materials.
5.5 Storage
Store packed items only under the following conditions
• Do not store outdoors.
• Store in a dry and dust-free environment.
• Do not expose to aggressive substances.
• Protect from direct sunlight.
• Avoid subjecting the machine to shocks.
• Storage temperature : –10° to +50 °C
• Maximum humidity: 60 %
• Avoid extreem temperature fluctuations
(to prevent build-up of condensation).
• Apply a coat of oil to all machine parts open to
possible rusting (corrosion protection).
• When storing for a period longer than 3 months,
apply a coat of oil to all machine parts open to
rusting (corrosion protection). Regularly check the
general condition of all parts and the packaging. If
necessary, refresh or re-apply the coat of
anti-corrosive agent.
• If the machine is to be stored in a damp environment,
it must be sealed in airtight packaging and
protected.
(desiccant).
Making adjustments and preparations
If no agreement has been made with the supplier to take back the packaging materials, help to protect the environ-
ment by reusing the materials or separating them according to type and size for recycling.
• Scrap waste metal
• Recycle all plastic elements
• Sort all other components and dispose of appropriately.

Warning! Risk of injury!
Improper assembly and installation can lead to serious physical injury or equipment damage.
For this reason, this work may only be carried out by authorised, trained personnel who are familiar with
how to operate the machine and in strict observance of all safety instructions.
Only assemble and install the machine if the machine and its parts are complete and intact.
6 Setup and installation
• Ensure that there is sufficient space to work around the
machine. Ensure there is ample distance between the
machine and other solid constructions such as a walls
or other machines.
• Keep the work area orderly and clean. Components
and tools that are not put in their correct place or put
away may be the cause of accidents!
• Install the safety equipment according to the
instructions and check that it functions properly.
Warning! Danger of fire!
Unprofessional installation may lead to a fire.
6.1 Safety instructions
Therefore:
• When connecting the machines to the dust extractor, only use steel piping or flame resistant hose and
ensure that these are earthed via metal coil, to prevent the build up of electro static electricity.
• In general when connecting the machines to the extractor, the machines should be earthed to prevent
the build up of electro static electricity.
• All electrical connections must be installed correctly by a qualified person.
• Electricity suppiy only in authorized field of ± 10% of network.
Requirements at the place of assembly:
• A dry, enclosed room.
• Operating/room temperature: +10° to +40°C
• Adequate ventilation e.g. to enable ample air
circulation for the machine cooling system.
• When positioning the machine in a room other
than the workshop, please ensure there is ample
ventilation.e.g. provided through an extractor fan.
Mimimum cross- sectional area 0,25 square meters.
• The working area must have an adequate load-
bearing capacity and stability and the walls must be
stable.
• Even floors without a slope.
• Provide sufficient light at the workstation.
• Ensure there is sufficient clearance for or from
neighbouring workstations.
