Appliance socket
The appliance socket is designed for electrical auxiliary equipment; see technical data for reference.
• Prior to plugging in an appliance, always switch off the machine and the appliance that is to be connected.
• Read the operating instructions for the appliance to be connected and observe the safety notes contained in these.
An earthed appliance socket is integrated in the machine. An external power tool can be connected there. The socket
has a 5 Amp thermal fuse to protect the machine against overload. If the power consumption gets too high the thermal
fuse activates and cut off the power on the socket outlet. The thermal fuse can be deactivated again by pressing the
knob. The socket features permanent power on when the switch is set to the position, i.e. the machine can be used
as an extension cord.
In position , the machine can be switched on and off from the connected power tool.
Dirt is picked up from the source of dust immediately. To comply with regulations, only approved dust-producing tools
should be connected.
The maximum power consumption of the connected electrical appliance is stated in the“Specifications”section.
Before turning the switch to position , ensure that the tool connected to the appliance socket is switched off.
3.3 Push & Clean
The“PC” machine is equipped with a semiautomatic filter cleaning system, Push & Clean. The filter cleaning system must
be actuated when the suction performance starts to fade. Regular use of the filter cleaning feature maintains suction
performance and increases the lifetime of the filter. For instructions, see the quick reference guide.
3.4 AFC – Auto Filter Cleaning
The“AFC” machine is equipped with an automatic filter cleaning system, Auto Filter Cleaning. A frequent cleaning cycle
will automatically run during operation to ensure that suction performance is always at its best.
If suction performance decreases or in very dusty applications, a manual filter cleaning operation is recommended:
• Switch off the machine.
• Close the nozzles or suction hose opening with the palm of your hand.
• Turn the switch to position“I” and let the machine operate at full speed for approx. 10 seconds with the suction hose
opening closed.
If suction power is still reduced take out the filter and clean it mechanically or replace the filter. For certain applications,
such as wet pick-up, it is recommended to turn off the Auto Filter Cleaning system. For details see chapter 3.1.
3.5 Antistatic connection
CAUTION
The machine is equipped with an antistatic system to discharge any static electricity that may develop during dust pick-up.
The antistatic system is located in the front part of the motor top and creates an earth ground connection to the
inlet fitting of the container. For correct operation, the use of an electrically conductive or antistatic suction hose is
recommended. When inserting the optional disposal bag make sure the antistatic connection is maintained.
3.6 Motor cooling filter
To protect the electronics and motor, the machine is equipped with a motor cooling filter. Clean the motor cooling filter
regularly.
For areas with a high concentration of fine dust in the surrounding air it is recommended to equip the machine with
an optional motor cooling filter PET to prevent dust from settling inside the air channels and motor. Contact your local
sales representative.

Mirka® Dust Extractor • 1230 M & 1242M • 230 V / 100–120 V • PC & AFC 87
en
CAUTION
If the motor cooling filter is clogged by dust the overload protection switch in the motor may be tripped. If this
happens, switch off the machine, clean the motor cooling filter and allow machine to cool for approx. 5 minutes.
3.7 Wet pick-up
CAUTION
The machine is equipped with a water level limit system which shuts off the machine when the maximum liquid level is
reached. When this occurs, switch off the machine. Disconnect the machine from the socket and empty the container.
Never pick up liquids without the water level limit system and filter in place.
Picking up liquids
• Do not pick up flammable liquids.
• Before liquids are picked up, always remove the filter bag/disposal bag and check that the water level limit works
properly.
• If foam appears, stop work immediately and empty the container.
• Clean the water level limiting device regularly and check for signs of damage.
Before emptying the container, unplug the machine. Disconnect the hose from the inlet by pulling out the hose. Release
the container clamps by pulling them outwards so that the motor top is released. Lift the motor top off the container.
Always empty and clean the container and water level limit system after picking up liquids.
Empty by tilting the container backwards or sideways and pour the liquid into a floor drain or similar. Refit the motor
top on the container. Secure the motor top with the container clamps. Sudden movements can accidentally trigger
the water level limiting device. Should this happen; turn off the machine and wait for 3 seconds to reset the device.
Continue to operate the machine afterwards.
3.8 Dry pick-up
CAUTION
Picking up environmentally hazardous materials. Materials picked up can present a hazard to the environment.
• Dispose of the dirt in accordance with legal regulations.
Unplug the machine before emptying after dry pick-up. Release the container clamps by pulling them outwards so that
the motor top is released. Lift the motor top off the container.
Main filter: Check the filter. To clean the filter you can brush or wash it. Wait until the filter is dry before re-starting dust
pick-up.
Dust bag: Check bag to ensure the fill factor. Replace dust bag if necessary. Remove the old bag. The new bag is fitted
by passing the cardboard piece with the rubber membrane through the vacuum inlet. Make sure that the rubber
membrane passes the raised part of the vacuum inlet.
After emptying: Close motor top on the container and secure the motor top with the container clamps. Never pick up
dry material without having a filter fitted in the machine. The suction efficiency of the machine depends on the size and
quality of the filter and dust bag. You should therefore only use an original filter and dust bags.
