Note!
This symbol means Note! and indicates a potential risk of material damage in
the event of incorrect use of the machine. If you see this symbol next to a
section of text, you must pay particular attention when reading through the text
and not carry out any operations of which you are unsure. This is to avoid

1.4 Transportation
Always ensure that the machine is emptied of dust and other particles before it is
transported, lifted or hoisted.
Always make sure that the machine is securely anchored to its surrounding during
transport to prevent it from coming into motion. Make sure that the securing straps, or
other equipment used for anchoring during transport, are tightened over non-moving
parts, e.g. the machine's chassis.
When lifting the machine, do so according to chapter Lifting the machine, page15.
Do not transport the machine on steep sloping surfaces, e.g. loading ramps, without
securing it properly, for example with a winch. This is a safety measure in case the
machine starts to roll out of control. Also make sure that people (including operator) in
the vicinity are at a safe distance in order to prevent personal injury, in the event that the
machine starts to roll out of control.
When the machine is to be hoisted, it must be securely anchored in the notches for
secure lifting (see position 4, Figure3-2, page9), which are found on both of the
chassis' long sides. To prevent the machine from tipping, make sure you pull with equal
force so the machine does not twist and end up on its side.
The swivelling wheel must be pointing forwards in the direction of travel.

The following items are included in the delivery. Contact your retailer if anything is
missing.

1.8 Handling and storage
The machine should be stored in a heated, dry area when not in use. Otherwise it may
be damaged by condensation and cold.
In the operating position, the dust extractor is 189 cm high, but it can be lowered so it is
only 154 cm high, which makes transport and maintenance work easier.
The machine can be lowered to the transport position, which facilitates transport and
maintenance work. See Figure3-2, page9when lifting. Make sure that all the
constituent parts of the machine are properly assembled before lifting.
Warning!
If handled carelessly, the machine can overturn and cause both personal injury
and damage to the equipment. Ensure that there are always two people present
when it is to be rotated.
1.9 Noise
Warning!
Always use hearing protection when using the machine.
This machine is tested for noise in accordance with ISO 3741 . For information on the
sound pressure level and sound power level for each model, see the table in Chapter
Technical data, page37.

Note!
The machine should be stored in a dry, warm (above zero) location when not in
use.
Note!
If the dust extractor is stored in a cold location (below zero), it must be placed
in a warm location (above zero) for at least two hours before use.

Discolouration on the top of the HEPA filter indicates that the main filter is not
functioning as it should. If the HEPA filter is dirty on the underside, the filter is
defective.

When checking the HEPA filter, the machine must be placed in the operating
position.
Note!
Anti-static hoses must be used when coupling to the grinder and dust extractor.

Warning!
If the catches are not properly located in the lugs, there is a risk that the dust
cylinder package can drop, with a consequential risk of crush injury.
4.2.2 Lowering the dust extractor to the transport position
The dust extractor can be lowered to the transport position, see Figure4-4, page15.
When the dust extractor is in the operating position, and you want to lower it to the
transport position, do as follows:
1. Lift the dust cylinder package with both hands, using the lifting handles, see
Figure3-1, page8. To avoid the risk of the suction system tipping, place a foot
on the collection plate for the waste bag.
2. Lift the dust cylinder package up and out a little, so the catches, see Figure4-2,
page13, release. Then let the dust cylinder package drop slightly and fold in the
dust cylinder package again, so the catches fasten in the lower lug on the chassis for
transport position.
