Device description

The dust extractor S 25 M / S 25 L is a combination device (COMB) for use as dry and wet extractor.
Wet suction cleaning should be carried out without filter bag. The filter cartridges are suitable for wet suction cleaning.

• INDUSTRIAL VACUUM CLEANER (IV ) exclusively for vacuuming deposited dust.
• DEDUSTER (DED) exclusively for extracting airborne dust from individual sources of dust, such as it arises for instance during machining and processing on machines and hand-operated equipment.

The dust extractor S 25 M / S 25 L, used as deduster, is suitable for the extraction of dry wood dust and dry shavings at individual sources of dust. If the deduster is duly connected to a hand-operated wood working machine with a dust source (for instance circular saw, planning machine, belt sander) and operated according to the instructions, the required extraction performance and separation quality are always guaranteed.

Safety devices

Danger
These devices are required for the machine’s safe operation and may not be removed or rendered inoperative.

• All mobile machine parts driven by electric motors are covered by stationary, securely fastened protective enclosures that can only be removed with the aid of tools.
• Testing according to EN 60335-1 and EN 60335-2- 69 showed that the safety requirements with regard to the electrical safety are also met when a water-air-mixture is vacuumed.
• The dust extractor is suitable for increased loads in case of commercial use. According to EN 60335-1 and EN 60335-2-69.

Use according to intended purpose

Danger
In general, it is not permitted to vacuum any combustible or explosive solvents, liquids such as petrol, oil, alcohol, thinners or materials with a temperature in excess of 60 °C. Otherwise there will be danger of explosion and fire! The dust extractor is not suitable for extracting dusts that are hazardous to health.

Dust extractors class M are suitable for vacuuming/extracting dry, non- combustible dusts, non-combustible liquids, wood dusts and hazardous dusts with STELs >0.1mg/m³.
Dust extractors class L are not suitable for vacuuming/extracting harmful dusts.

The dust extractor S 25 M / S 25 L is particularly suited for vacuuming off electrical tools. Further applications are at the construction site where large amounts of moist and dry fine dust arise, for inside cleaning of motor vehicles and everywhere moist and dry materials have to be disposed of, mopping water has to be vacuumed, clogged water basins and drains have to be emptied, “flooding” in bath, kitchen or basement has to be removed or the bothersome puddle in front of the front door has to disappear.

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.

Switching on and off

Switch positions for IV operation (industrial vacuum cleaner) (fig. 1)

0 = Off
I = On (manual operation) The volume flow display is switched over to a fixed value which causes the signal lamp to blink if the air speed drops below 20 m/s.
A = Stand-by mode for automatic switch on/off function (dust extractor is switched on and off by the electrical tool).

Switch positions for DED operation (deduster) Fig.1

RA = Device models with “RA” equipment can be operated as under “A”. Filters are cleaned automatically on reaching the set minimum flow rate during the next work break (switch position RA).

The dust extractor S 25 M / S 25 L is equipped with an electronic suction force regulator. The turning knob 2 can be used to adapt the suction power to the material to be vacuumed.

The socket outlet 4 is provided for the connection of an electrical tool (A/RA mode).

Danger
The electrical tool must be switched off when it is connected. When the power plug is plugged in, the socket outlet is always live, irrespective of the switch position. In switch position “0”, the socket outlet can be used as extension cord (e.g. for lamp). Connected load: Dust extractor and connected device max. 16 A.

To avoid excessive start-up peaks, the dust extractor is equipped with a starting current limit (soft start).

Danger
While the dust extractor motor is coasting down, the operating mode selection switch may not be turned until the dust extractor has come to a standstill, otherwise the device must afterwards be switched via the 0-position to guarantee the perfect functioning of the electronic system

Hints and information

• When vacuuming dry materials, the folded filter 5 (fig. 2) must be completely dry.
• During wet vacuuming, the built-in sensor prevents the maximum filling level in the container from being exceeded. The device no longer vacuums when the container is full. Switch off motor. Pull the dust extractor plug and empty the container.
• If the sensor responds when vacuuming larger amounts of liquid (more than one container filling), switch off the device and empty the container.
  • If the volume flow display 3 (fig. 1) lights up on restart, this may have the following reasons:
  • Container, filter bag 8 (fig. 4) full.
  • Extraction hose clogged.
  • Air cross sections of the dust generator too small.

On completion of work, but especially if you do not intend to use the device for a longer period of time, you should:

• Discharge any dirt and liquids.
• Store the extraction hose such that there are no kinks.
• Neatly reel up the mains cable and protect it against damage.

Service and maintenance

Danger
Pull the power plug during all service work.

After longer periods of operation, MAFELL recommends to take the device to an authorised MAFELL customer service shop for inspection.

The storage place must be dry and frost-protected. If the device fails despite diligent manufacturing and test procedures, the repair must be carried out by an authorised customer service station for MAFELL products.

Danger
Only use MAFELL accessories and spare parts. Have components, the replacement of which has not been described in this document, replaced at a MAFELL customer service station.

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.
When carrying out maintenance or repair work, all soiled objects which cannot be cleaned in a satisfactory manner must be disposed of. Such objects must be disposed of in impervious bags in compliance with the valid regulations for the disposal of such waste.

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.

Motor protection filter

The folded filter cartridges are located next to the motor protection filter 6 (fig. 2). If they are heavily soiled, rinse out and reinsert in dry condition. Damaged motor protection filters must be replaced.

Disposal information

• Filter bags, filled with normal domestic dirt are disposed of with the normal domestic waste.
• Filter bags, filled with hazardous waste: Enquire at your municipality or at the responsible authority.
• The folded filter cartridge is disposed of as hazardous waste in a plastic bag, if necessary
