WARNING! RISK OF INJURY OR DEATH!
• Hearing impairment due to noise
• Health eects due to exposure to dust, in particular when working with hardwood.
safEty
17
Observe the following safety regulations to
ensure the work is carried out safely.
WARNING
GENERAL INFORMATION
Always start the extraction unit rst before
using the machines. This will avoid the ma-
chines being used without the wood being
extracted. Once the work has been comple-
ted, turn o the machines before turning o
the extraction unit.
OPERATORS
The machine operators must read this in-
struction manual so that they can use the
extraction unit safely and correctly.
FILTER FAILURE
Do not use the extraction unit if there is a l-
ter failure. This will prevent dust from getting
into the fan compartment and around the ex-
traction unit. If this does happen, then there
may be a risk of exposure, a re risk or risk of
an explosion.
SUPERVISION
Always pay attention to the extraction
unit when it is in use.
ENTRAPMENT HAZARD
Never insert your hand or arm in the inlet
or other parts of the extraction unit.
SOUND PRESSURE LEVEL
The sound pressure level of the machine is less than 70 dB (A). In combination with other machines
installed on the work oor, hearing protection is recommended or prescribed. We refer herein to
the laws of the user's country. The specied sound pressure level values are emission values of the
extraction unit and therefore not safe workplace values. Although there is a correlation between
emission and immission values, it cannot be reliably determined whether additional workplace
precautions are needed. Factors that can inuence the existing workplace include the duration of
exposure, the nature of the workplace and other inuences in the neighborhood. The permitted
maximum workplace values may also vary from country to country. This information must be re-
trieved by the user in order to make a good estimate of the danger or risk.
To avoid the risk of an explosion, keep the
area around the extraction unit clean and
free of dust.

Viewing window to check the
direction of rotation
The following steps must be carried out during the ini-
tial commissioning of the extraction unit:
• Check the direction of rotation of the fan. This must
match the arrow stickers. A wrong direction of rota-
tion can be recognized by a very low suction power.
• If the direction of rotation is wrong, it must be re-
versed. This can be done with the help of the CEE
phase exchanger.
• Turn 2 of the plug pins with a screwdriver. Both pins
are recognizable by the black circle on which they
turn.
• Check that there are no unwanted leaks. (A leak
may be identied by a whistle).
The extraction unit will start when the mode switch is set
to the Hand-start position. The full suction power is imme-
diately available after starting the extraction unit.
The extraction unit stops immediately when the mode
switch is set to the Stop-Auto position.
Note: After each shutdown
a cleaning cycle takes place.
If automatic switch-on is used, the position switch is set
to the Stop-Auto position: See the relevant manual.
DIRECTION OF ROTATION
Stop the machine immediately if a
wrong direction of rotation is detec-
ted, to prevent excessive heating.

Filter cleaning DM-250/M
Every time the extraction unit is switched o, an automatic cleaning cycle follows by
means of the motor vibration of the lter hoses. If during operation the indicator lamp of
the dierential pressure switch lights up, the extraction unit must be switched o as quic-
kly as possible so that the cleaning cycle can be carried out.
Filter cleaning DM-250/P
The lter cleaning is performed automatically by the controller. The lter cleaning cycle
starts automatically after the extraction unit is switched o. The pause times between
the pressure surges are xed and cannot be changed by the user. If desired, the cleaning
can also be operated manually, when the extraction unit is at a standstill. If dust-produ-
cing machines (belt or broad-belt sanders) are largely suctioned o, it is recommended
to switch o the suction unit briey after a continuous working time of 30 minutes. This
starts automatic cleaning and after approximately 2 minutes the extraction unit is ready
for operation again.
Dust and chips are collected in the waste containers during operation. The level can be
checked through the viewing window. Dust can be stored up to a total amount of 500
liters. If the amount of waste exceeds the limit shown on the container, the extraction unit
must be switched o. Wait for the end of the cleaning cycle before loosening the waste
container so that dust and chips do not fall out of the extraction unit. By tightening the
container lock, the waste container can be rolled forward from the extraction unit. Care-
fully remove the plastic waste bag and seal it well before disposing of it according to local
guidelines. When placing a new plastic waste bag, it must lie at on the walls and contain
as little fold as possible on the edges of the container.
WARNING
Hazard from dust inhalation:
For working with wood dust, a dust mask must in any case be used (lter mask with parti-
cle lter, class 2). It must be avoided that bystanders can come into contact with the dust.
Avoid sources of ignition and electrostatic charge.
20 gEbruIk
If more than one machine is connected
to the extraction unit, each machine
must be shut o with a slider from the
extraction unit. Make sure that the sli-
ders on the machines that are not being
used are closed. Use of automatic sliders
is recommended.
The extraction unit DM-300 was built ac-
cording to the GS-HO-07, version 11.2015,
and are tested to this standard by the Prüf-
und Zertizierungsstelle der Holzgenos-
senschaft, Vollmoellerstrasse 11, D-70563
Stuttgart. The extraction units are there-
fore suitable for extracting and separating
dry (moisture content <30%) wood dust
and chips, whereby the residual materi-
al standard 3 (H3): 0.1 mg/ mis certainly
achieved.
The extraction unit is not suitable for the
extraction of:
• Sticky substances such as glue residu-
es and overspray
• Welding smoke, smoke, etc.
• Spark-forming machines, such as me-
tal grinding machines
• Liquids
• Explosive or equivalent substances, ac-
cording to §1 of the German explosives
law, SprenG, or substances from dust
explosion class St 3.
The extraction unit must not be placed in a
potentially explosive environment.
The extraction unit can only be set up out-
side if it is suciently protected against
rainwater.
