the installation site.
General risks during internal transport
WARNING!
Risk of misuse!
Misuse of the Air Extraction Units can lead to dange-
rous situations.
- Only operate the extraction system within the perfor-
mance range specified in the technical data.
- Do not operate the extraction system in potentially
explosive areas
- Never bypass or override the safety devices.
- Only operate the extraction system in a technically
perfect and fully assembled condition.
- Solid bodies, e.g. Wood pieces (over an edge length
of 1 cm) as well as metal parts and stones etc. must
not be vacuumed. Such bodies will damage the im-
peller (disclaimer of warranty).
WARNING!
Severe or fatal injuries may occur if parts of the
machine tumble or fall down from the forklift truck,
pallet truck or from the transport vehicle. Follow the
instructions and information on the transport box.
Note the total weight of the machine. The weight of
the machine is indicated in the "Technical data" of the
machine. When the machine is unpacked, the weight
of the machine can also be read on the rating plate.
Only use transport devices and load suspension gear
that can hold the total weight of the machine.
WARNING!
The use of unstable lifting and load suspension
equipment that might break under load can cause
severe injuries or even death. Check that the lifting
and load suspension gear has sufficient load-bea-
ring capacity and that it is in perfect condition.
Observe the accident prevention regulations issued
by your Employers Liability Insurance Association or
other competent supervisory authority, responsible
for your company.
Fasten the loads properly.
WARNING: DANGER OF TIPPING
The device may be lifted unsecured by a maximum
of 2cm.
Employees must be outside the danger zone, the
reach of loads.
Warn employees and, if necessary, advise employ-
ees of the hazard.

Technical Data
ASA-Series | Version1.05 7
Devices may only be transported by authorized and qua-
lified persons. Act responsibly during transport and al-
ways consider the consequences. Refrain from daring
and risky actions.
Gradients and descents (e.g. driveways, ramps and the
like) are particularly dangerous. If such passages are
unavoidable, special caution is required.
Before starting the transport check the transport route for
possible danger points, unevenness and disturban-ces
as well as for sufficient strength and load capacity.
Danger points, unevenness and disturbance points must
be inspected before transport. The removal of danger
spots, disturbances and unevenness at the time of trans-
port by other employees leads to considerable dangers.
Careful planning of internal transport is therefore essen-
tial.
4.2 Packaging
All used packaging materials and packaging aids are re-
cyclable and should be taken to a materials recycling de-
pot to be disposed of.
The delivery packaging is made of cardboard, so please
dispose carefully by having it chopped up and given to
the recycling collection.
The film is made of polyethylene (PE) and the cushioned
parts of polystyrene (PS). Deliver these substances to a
collection point for recyclable materials or to the waste
disposal company which looks after your region.
4.3 Storage
Thoroughly clean the individual functional parts in their
original packaging and the complete extraction system in
a dry, clean and frost-free environment (U-25 ° C - + 55 °
C). The extraction system must not be shut down with
chemicals in a room.

Care, maintenance and repair
ASA-Series | Version1.05 11
9 Care, maintenance and repair
9.1 Maintenance
General:
The unit is designed for the extraction of dry dust and
chips in dust class L.
1.Clean the filter when the extraction capacity falls due to
the filter being blocked with dust.
2.Change the chip sacks promptly.
3.Only use original chip sacks
4. Check the direction of rotation occasionally- compare
the outfeed motor cooling fan with the directional ar-
row). If the direction of rotation is incorrect, the capa-
city will be inadequate and the motor will suffer exces-
sive heat generation. Only have the rotating field chan-
ged by a trained electrician.
Disposal of collected goods
When the filling container is full or when the maximum
permitted level is reached:
Step 1: Turn off the dust generating machine and unplug
the power cord.
Step 2: Carry out the cleaning again.
Step 3: Turn off the exhaust system and disconnect the
power plug.
Step 4: After loosening the tension levers, lower the
filling tank and pull out to change the chip bag.
Step 5: Carefully close the chip bag and remove it from
the container.
Step 6: Insert the new chip bag into the container.
Changing the filter bag
Step 1: Hook the loop of the filter bag into the holding rod
of the extraction system.
Step 2: Mount the extension bar to the end of the filter
bag holding bar. Lift the support rods with the fil-
ter bag attached and insert the end of the sup-
port rods into the holes in the bracket. NOTE:
The flared end of the filter bag extension pre-
vents the rod from sliding through the bracket.
DANGER!
- After switching off the device, the impeller continues
to run for approx. 1 to 3 minutes.
- Never brake the impeller by hand or with objects.
- If the device is out of operation for more than 1
week, it is generally necessary to rotate the motor
shaft and fan shaft once a week in order to avoid
punctual loading of the bearings and thus bearing
