Check dust covers

Check that the dust covers in the dust extractor and pre-separator can move freely
without jamming. Check that rubber cloth is undamaged; clean the surface if needed.
Check that the dust covers seal against the seal surface on the cylinder wall.
5.3.3

Check the sock filters

Warning!
If handled carelessly, the dust extractor can overturn and cause both personal
injury and damage to the equipment.
Warning!
The dust that is sucked up is harmful if inhaled. Follow local regulations and
use breathing protection.
1. Start with the dust extractor in the operating position, see Figure 4-1, page 15.
2. Lower the dust extractor to the service position, see under Lower the dust
extractor to the service position,
3. Shine a torch inside to see the filter.
4. If the filter is clogged, the filter should be cleaned. For instructions on how to
clean the filter, see under Manual cleaning of the filter using the slide gate, page
22. Carry out a further check of the sock filters, if necessary.

Warning!
There is a risk for crush injuries when the dust extractor is lowered to
the service position. Make sure your hands are not in the way when the
upper cylinder sections tips against the handle.
Tip!
The surface of the filter should be dull. If the surface is shiny, the filter
is clogged.
Tip!
If the sock filter cassette is dismantled (according to Replace sock
filters, page 37), it can be seen whether it is dusty on the inside of the
top section. In this case, one of the filters has failed or there is a leak
somewhere else. The HEPA filter must be inspected if the sock filters
exhibit dust leakage.
