Use according to the intended purpose

The dust extractor can be used for extracting wood shavings and wood dust from wood processing devices / machines, the hose connector of which has a diameter of 35 mm. Dust extractors class M are suitable for vacuuming/extracting dry, non-combustible dust, non-combustible liquids, wood dusts, and hazardous dusts with STELs >0.1mg/m³. Any other use than described above is not permissible. The manufacturer cannot be held liable for any damage arising from such other use. To use the device as intended, observe the operating, maintenance and repair conditions prescribed by Mafell. This device is also not suitable for operation outdoors in the rain or in rooms with potentially explosive atmospheres. The dust extractor S 35 M may only be used, set up and serviced by persons who are acquainted with the device and have been instructed about the hazards involved. Corrective maintenance work must be carried out by MAFELL authorised dealers or MAFELL customer service stations. The safety instructions applicable in the respective country of use as well as other generally recognised rules pertaining to safety and occupational health must be observed.

Residual risks

• Touching live parts with the housing open and the mains plug not removed.
• Emission of dusts during extended operation with damaged folded filter.
• While exchanging a filter bag or emptying the container, the inhalation of dust cannot be ruled out (respiratory protection).
• Unauthorized changes to the device exclude the manufacturer’s liability for any damages resulting thereof.

Safety instructions

Setting / Adjustment

Assembly

• Pay attention that the container’s two snap locks have safely engaged in the recesses on the motor hood.
• Push the suction hose fitting over the container’s suction opening and turn it until thehose fitting engages.

Mains connection

The dust extractor S 35 M is equipped with protective earthing acc. to class I and may therefore only be connected to sockets with protective earth conductor. Prior to commissioning make sure that the mains
voltage agrees with the operating voltage stated on the machine’s rating plate

Changing the folded filter cartridge

•  Shake off the folded filter cartridges before changing the filter.
•  Using a coin or similar object, turn the catch 7 ( on locking bolt 9 anticlockwise by 90° and push the locking bolt 9 to the rear.
•  Swing open the hood and remove the filter cartridge 5   towards the top.
•  Immediately seal the removed folded filter cartridges in a dust-tight plastic bad and dispose of in accordance with the instructions.
•  Insert the new filter cartridges and pay attention to a neat and tight fit of the filters.
•  Fold down the hood and return to its initial position by slightly pressing on the locking bolt 9  . The device is now once more closed.

Changing the motor protection filter

The folded filter cartridges are located next to the motor protection filter 6 If they are heavily soiled, rinse out and reinsert in dry condition. Damaged motor protection filters must be replaced

Changing the non-woven filter bag

•  Switch off the device to change the non-woven filter bag.
•  Pull the dust extractor’s plug.
•  Open the snap locks 10
•  Detach the upper part of the dust extractor from the container 12
•  Pull the filter bag carefully from the intake port.
•  Close the flange of the filter bag by turning down the cover.

Changing the PE-discharge and disposal bag

•  PE-discharge and disposal bag: Switch on dust extractor, shake off folded filter cartridges. Switch on dust extractor.
•  Wear mouth guard.
•  Remove suction hose, close intake port with plug*.
•  Open lateral locks, remove top part. Before putting down the top part, switch on at switch position >IR< so that possibly released airborne particles are extracted.
•  Carefully seal PE-discharge and disposal bag with the enclosed sealing tape.
•  Pull flange carefully off the intake port and close.
•  Carefully remove PE-discharge and disposal bag from the container.
•  Dispose of extracted material in accordance with the legal provisions.

Disposal of filter bags

• Dispose of the filter bag in an impervious bag in compliance with the valid regulations for the disposal of such wastes.
• Filter bags, filled with normal domestic dirt are disposed of with the normal domestic waste.
• PE-discharge and disposal bag, filled with hazardous waste: Enquire at your municipality or at the responsible authority.

Inserting the filter bag

Inserting the non-woven filter bag

•  Pull the flange completely over the intake port. Operation of the rotary valve
•  Push rotary valve* from the inside to the outside, rotate by 180° (see marking) and push once more to the inside through the intake port.
•  Place rotary valve* into the intake port with the marking
•  pointing upwards.

Inserting the PE-discharge and disposal bag

• Only dust extractors class M with special container and rotary valve in the intake port of types S 35 M are suitable for use with PEdischarge and disposal bags. Operation of the rotary valve
•  Push rotary valve* from the inside to the outside, rotate by 180° (see marking) and push once more to the inside through the intake port.
•  Place rotary valve* into the intake port with the marking  pointing upwards.
•  Push flange completely over intake port, place top opening of bag across rim of container
•  Put top part onto container and close lateral locks.

Operation

Switching on and off

• Switch positions 1 (Fig. 1)
•  Put plug in socket outlet

• 0< = Dust extractor switched off

• I< = Dust extractor switched on without vibration function

• IR< = Dust extractor switched on with automatic vibration function

• AR< = Dust extractor on standby Only when the tool is switched on will the dust extractor switch onautomatically.

• After switching off the tool, the dust extractor will run on for approx. 10 sec.; this is to prevent any residual amounts remaining in the hose.
•  Set dust extractor to switch position >0<.
•  Pull power plug when finished.
•  For storage purposes, fix the suction tube on the container backplate by inserting it in the accessory depot*.
•  The hose ends can be stuck together to prevent any dirt particles from escaping.

Permanent filter cleaning

The dust extractor is equipped with an electro-magnet filter cleaning system, that can be used to shake adhering dust off the folded filter cartridges. The folded filter cartridges are cleaned alternatively in succession so that continuous working is guaranteed Constant fill level monitoring of the filters by differential pressure measurement for absolutely accurate need-controlled filter cleaning during operation.  This guarantees a constantly high air flow during operation, even for critical types of dust.

Maintenance

For maintenance by the user, the device must be disassembled, cleaned and serviced as far as this is feasible without causing any danger for the maintenance personnel and other persons. Suitable precautions include cleaning before
disassembly, providing for locally filtered forced venting at the place where the device is disassembled, cleaning the maintenance area and suitable personal protective clothing. On machines class M, the outside of the machine
should be cleaned by means of dust extraction methods and wiped clean or should be treated with sealant before they are removed from the hazardous
area. All machine parts must be considered contaminated if they are removed from the hazardous area and suitable action must be taken to avoid the dust from being dispersed. Such objects must be disposed of in impervious bags in compliance with the valid regulations for the disposal of such waste. The method to be applied when removing covers for cleaning purposes from areas that are not dust-tight should also be specified in the operating manual.

Servicing

If the dust extractor’s suction performance decreases, and even cleaning the filters 5 (fig. 2) after replacement of the filter bag 8 (fig. 4) does not increase the suction performance any more, the folded filter cartridges 5 (fig. 2) must be renewed. Usually it is sufficient to clean the folded filter cartridges 5 from time to time, using a soft brush and water. Allow to dry before reinserting, to prevent the dust from clinging to the moist filter. To avoid heavy soiling of container and filter, remove dry material from the container before vacuuming liquids. Dry suction cleaning only with completely dried-out device. Do not clean container and accessories with abrasive commercial detergents. Regularly clean the water sensors 13 (fig. 3) and check them for possible damages.
