Operation

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.
5.1 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 with automatic vibration function
  Only when the tool is switched on will the dust extractor switch on automatically.
  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.

Preselection switch for minimum volume flow signal (horn and light) on dust extractors class “M”.
In mode >AR< and >IR, the following setting is made, depending on the hose diameter:

For options 0 27 mm and 0 21 mm, the speed is reduced.

The dust extractor S 35 M is equipped with an electric suction force regulator. The turning knob 2 can be used to adapt the suction power to the material to be vacuumed.

• Put power plug of the dust extractor into the socket outlet.
• Place switch for normal mode without vibration function to “I”, for normal mode with vibration function to “IR” or for standby mode to “AR”.
• Dust extractor is ready for extraction.
• After extraction, put switch to “O”.
• Dust extractor is switched off
• Pull power plug of the dust extractor from the socket outlet.
• Clear away mains cable.
• Remove electric tool.

The socket outlet 4 is intended for connection of an electric tool (IR/AR mode).
To avoid excessive start-up peaks, the dust extractor is equipped with a starting current limit (soft start).
5.1.1 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. 5.2 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.
6.1 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.
6.2 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.
