Check the status of the ground strap, its
fasteners and its entire functioning before
start-up and at regular intervals.
Vacuum only using all the filter elements;
otherwise, the suction motor can get dam-
aged and this can be hazardous to health
on account of increased release of fine
dust particles!
According to the applicable regulations,
industrial vacuum cleaners (IS) of catego-
ry 1 are not suited for use on work ma-
chines.
Appliances of category 1 are not suitable
for sucking in dusts or fluids with high risk
of explosion and mixtures of combustible
dust with fluids.
The applicable safety regulations for the
materials to be treated need to be fol-
lowed.
From a safety point of view, industrial vac-
uum cleaners with protection against dust
explosions are not suitable for sucking in
substances that are explosive in nature,
fluids and mixtures of combustible dust
with fluids according to section 1 of the
Explosives Act.
In case of emergency (while sucking in com-
bustible materials, when there is a short-cir-
cuit or some other electrical defect), switch off
the appliance and remove the plug from the
socket.
Note
Additional regulations can be applicable to
dusts with an ignition capacity below 1mJ.
You can use this appliance to take up all types
of dust up to dust class H. It is statutorily nec-
essary to use a safety filter bag (see Filter sys-
tems for order number).
This appliance is suitable as an industrial vac-
uum cleaner to vacuum dry dusts with MAK val-
ues.
Î Bring the appliance to working position
- secure it, if required, with parking
brakes.
Î Insert the suction hose into the suction
hose connection.
Î Attach the desired accessoried to the
suction hose.
Î Ensure that the vacuum material con-
tainer has been inserted properly.
WARNING
The highest allowed net impedance at the
electrical connection point (refer to techni-
cal data) is not to be exceeded.

Warning
Avoid rolling up or bending the hose while
using the vacuum cleaner.
You must insert a safety filter bag into the
vacuuming material container to empty the

regulations.
The machine is equipped with a suction
power monitor. If the air speed in the suc-
tion hose falls below 20 m/s, the manome-
ter will display 19.5 kPa:
Perform the following activities to regain the
prescribed air speed of more than 20 m/s:
Î Switch off the appliance using the On/
Off switch.
Î Clean the filter (see chapter "Cleaning
the filter").
Î Check suction hose and attachments
for blocks.
If these measures do not lead to the de-
