Dust/Chip Extraction
Before any work on the power tool, remove
the battery.
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– To achieve a high degree of dust extrac-
tion, use the vacuum cleaner type
GAS 25/GAS 50/GAS 50 M for wood or
GAS 50 MS for wood and/or mineral dust
in conjunction with this power tool.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.
Mounting the Extraction Adapter (see figure B)
Fasten the extraction adapter 25 to the base
plate 6 with the fastening screw 24.
A vacuum hose with a diameter of 35 mm can be
connected to the extraction adapter 25.
The extraction adapter may not be mounted
when no external dust extraction is connect-
ed. Otherwise the extraction channel can be-
come clogged.
Do not connect a dust bag to the extraction
adapter. Otherwise the extraction system can
become clogged.
To ensure optimum extraction, the extraction
adapter 25 must be cleaned regularly.
External Dust Extraction
Connect the vacuum hose 26 to a vacuum cleaner
(accessory). An overview for connecting to vari-
ous vacuum cleaners can be found at the end of
this manual.
2 609 932 630 | (5.6.08)
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
Operation
Operating Modes
Before any work on the power tool, remove
the battery.
Adjusting the Cutting Depth (see figure C)
Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the
blade teeth should be visible below the work-
piece.
Loosen the clamping lever 28. For a smaller cut-
ting depth, pull the saw away from the base plate
6; for a larger cutting depth, push the saw toward
the base plate 6. Adjust the desired cutting depth
at the cutting-depth scale. Tighten the clamping
lever 28 again.
The tightening tension of the clamping lever 28
can be readjusted. For this, unscrew the clamp-
ing lever 28, and screw it back again turned off-
set by at least 30° in counterclockwise direction.
Adjusting the Cutting Angle
It is best to place the power tool on the face side
of the blade guard 4.
Loosen wing bolt 11. Tilt the saw sidewards. Ad-
just the desired setting at the scale 13. Tighten
wing bolt 11 again.
Note: For bevel cuts, the cutting depth is smaller
than the setting indicated on the cutting-depth
scale 27.
