Flow rate warning

CAUTION
Check that all the filters are present and prop-
erly fitted.
The machine is equipped with a system to monitor
air velocity and Dust Class H filter condition
picking up dust with occupational exposure limit val-
ues, check the volume flow monitor.
1. When the motor is running, hold the suction
hose shut to reduce the volume flow. The LED
indicator on front panel will light after approx. 1
second. The acoustic warning sounds after some
additional seconds.
2. Set the diameter setting to the actual hose size.
When LED indicator lights, air velocity is
below 20 m/s.
1. Check if container or filter bag is full.
2. Check if air flow is reduced in suction hose,
tube/nozzle, filter.
When LED indicator lights, Dust Class H or
*)
HEPA filter is missing, damaged or clogged.
1. The filter needs to be installed or replaced to
obtain needed air flow.
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 placed in front part of the
motor top and creates an earth ground connection to
the inlet fitting of the container.
For proper function the use of an electrical conduc-
tive or antistatic suction hose is recommended.
1. When inserting the optional disposal bag make
sure the antistatic connection is kept.
3.6

Cooling air filter

To protect the electronics and motor, the machine is
equipped with a cooling air diffusor. Clean the cool-
ing air diffusor regularly.
For areas with a high concentration of fine dust in
the surrounding air it is recommended to equip the
machine with an optional cooling air filter cartridge
to prevent dust from settling inside the air channels
and motor (Order No. CFA1133-ASB-2).

CAUTION
If cooling air filter is clogged by dust the over-
load protection switch in the motor can be
activated.
1. In such case switch off the machine, clean cool-
ing air filter and allow machine to cool for ap-
prox. 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.
1. When this occurs, switch off the machine.
2. Disconnect the machine from the socket and
empty the container.
3. Never pick up liquids without the water level limit
system and filter in place.
4. Do not pick up flammable liquids.
5. Before liquids are picked up, always remove the
filter bag/wastebag and check that the water
level limit works properly.
6. If foam appears, stop work immediately and
emty the tank.
7. 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 latches by pulling them outwards
so that the motor top is released. Lift up the motor
top from container. Always empty and clean the con-
tainer and water level limit system after picking-up
liquids.
Empty by tilting the container backwards or side-
ways and pour the liquids into a floor drain or similar.
Put back the motor top to the container. Secure the
motor top with the latches.
Heavy maneuvers can, by mistake, 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.
