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 .
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 .
