22 (see Elex V, § 2 (4)). They should only be used to extract surface dust.

ξType 1 dust-explosion protected dust extractors are technically suitable for extracting combustible dust (moist and

dry) of dust-explosion classes St 1 and St 2 (Kst value < 300 bar x m x s-1) in zone 22 (see Elex V, § 3 (4)). They are not suitable for extracting objects (from wood- processing machines) where active ignition sparks cannot be ruled out. They should only be used to extract individual sources of dust.

ξFrom a safety viewpoint, dust-explosion protected industrial vacuum cleaners and dust extractor are unsuitable for vacuuming or extracting materials that pose a danger of explosion or similar based on § 1 Explosive G, dust of dust- explosion class St 3, and flammable liquids.

ξThe use of electric coupling devices and adapters is not permitted during operation.

ξThe dust-collection container must be emptied when necessary, but should always be emptied after use. Only original replacement parts should be used.

ξFluids, aggressive gases, easily flammable materials or glowing particles (glowing embers or similar) should not be extracted. It is prohibited to use the dust extractor e.g. in paintshops. Extraction at wood-processing machines where active ignition sparks and glowing embers are expected (e.g. multiple-bladed saws) is prohibited.

ξDo not extract from sources of sparks! Do not extract from spark-generating machines!

ξCaution! Clean the machine after it has been used, but a minimum of once a day! (See Section 9)

Caution:

Safety equipment that prevents or eliminates hazards must be maintained regularly and checked a minimum of once a month for safe, faultless function by a skilled expert in accordance with § 39(3), VBG 1 – General regulations – and in accordance with TRGS 560. See Section 14.

4Preventing danger

•Mechanisms

All moving machine components driven by electric motors must be covered by static, safely attached protective panelling that can only be removed using tools.

Other risks: If a panel that can only be disassembled using tools is removed, there is a possibility of injury from the operating machine.

• Electrics

All electrical components must be covered by static, safely attached protective panelling that can only be removed using tools. The machine corresponds to safety class I in accordance with EN 60 335.

Other risks: If a panel that can only be disassembled using tools is removed, there is a danger of electric shocks.

• Dust

Using disposable dust bags with a sealable opening ensures dust-free disposal of collected material.

Other risks: When a dust bag is changed, there is a risk of inhaling dust.

Compliance with the instructions in Section 10 (Disposing of collected material) minimises these dangers.

5 Delivery and assembly

The machine is already fully assembled.

1)Remove the packaging foil.

2)Unscrew and remove the corner plate that secures the machine to the pallet.

3)Lift the machine from the pallet with help from a second person.

9 Viewing window (filling level)

7 Initial Operation

Note: The extraction hose and dust bag supplied are located inside the container (8).

7.1 Setting up

The dust extractor should be set up as close to the wood-processing machine as possible. It should be set up on a level surface. Lock the rear machine roller.

7.2 Inserting the dust bag

1)Fold up both latches (1) simultaneously: The container (8) is lowered.

2)Roll the container forwards.

3)Insert new dust bag in the container (make sure that the dust bag rests as flush against the container wall as possible) and fold approx. 6-10 cm over the edge of the container, minimising creases while doing so (see Figure on page 3).

4)The dust bag should rest flush in the area around the viewing window (9) so that the filling level can be seen clearly.

5)Roll the container under the dust extractor.

6)Close both latches (1) : The container is raised and forms a tight seal with the dust extractor.

The next time the machine is switched on, a vacuum is generated in the container. The dust bag then automatically nestles against the wall of the container, optimising use of the dust bag capacity.

7.3 Connecting the extractor hose

Only use electroconductive hoses. Hoses made from plastic must be flame-retardant.

1)At one end of the spiral hose, strip the metal spiral so that approx. 5 cm of the metal spiral protrudes.

2)Cut off the piece of hose that the metal spiral was removed from.

3)Bend the stripped piece of metal spiral in such a way that it protrudes inside the spiral hose.

4)Push the end of the hose (and one hose clamp) over the extractor connection piece from the dust extractor and secure with the hose clamp: Attach the hose clamp in such a way that the stripped metal spiral is pressed against the extractor connection piece on the dust extractor to ensure that there is an electroconductive connection.

ENGLISH

Make sure that the electrical connection between the hose and extractor connection piece on the dust extractor is perfect.

7.4 Power supply

Before plugging in check to see that the rated mains voltage and mains frequency, as stated on the rating label, match with your power supply.

When connecting the three-phase version (SPA 2002 D), pay attention to the correct rotational direction.

7.5 Switching On and Off

After connecting the extraction hose to the wood-processing machine:

1)first switch on the dust extractor at the on/ off switch (6),

2)then switch on the wood-processing machine

Perform these actions in reverse order when switching off the machines.

8Monitoring the minimum volume flow rate

The vacuum should be monitored at the pressure gauge (4).

a.) Use as a dust extractor

Wood-processing machines with different extraction connection piece diameters can be connected to the dust extractor. Pay attention here that the extracted volumetric flow does not fall below the minimum quantity. This minimum volumetric flow depends on the diameter of the connection piece on the machine generating the dust.

There are red areas on the pressure gauge scale, which are marked with the extractor connection piece diameters.

If the pointer of the pressure gauge is in the red area of the extractor connection piece being used, the filter must be cleaned.

Note: The minimum volumetric flow on the dust extractor is monitored by measuring the vacuum upstream of the ventilator. If the maximum permitted vacuum value is exceeded, the pointer moves to the red area.

If the diameter of the extractor connection piece or minimum volumetric flow at the machine generating dust is between the range of values in the table, the next largest diameter is used for monitoring the value.

The ratios are shown in the following table:

Meaning of columns:

Column 1: Diameter of extractor connection piece on the wood-processing machine.

Column 2: Minimum volumetric flow in extractor connection piece at 20 m/s.

Column 3: Possible vacuum at start of extraction hose (2.5 m long). Interface between machine generating dust and dust extractor, at minimum volumetric flow. The manufacturer of the wood-processing machine specifies the vacuum required for the machine. This value must be less than the value for the dust extractor in order for extraction from the wood-processing machine to occur as specified.
