Inserting/Replacing Saw Blades
(see figure B)
When mounting the saw blade, wear protec-
tive gloves. Danger of injury when touching
the saw blade.
Loosen and remove the knurled screws 7 togeth-
er with the spring washers and the cover plate 6.
Firstly, insert the saw blade pair 3 into the
bottom of the saw blade guide 2, paying at-
tention that the longitudinal grooves of the
saw blades engage into the guide pin of the
saw blade guide.
Secondly, locate the top of the saw blade
pair 3 onto the drive tappets, ensuring that
the saw blades are properly seated in the
saw blade guide.
Place the cover plate 6 onto the set screws on
the housing and secure them with the knurled
screws 7, ensuring that the spring washers have
also been mounted.
Mounting the Base Plate (see figure C)
Insert the saw blade guide 2 into the correspond-
ing notch on the base plate 4. Tighten the ten-
sioning screw 8.

Dust/Chip Extraction

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.
– Use dust extraction whenever possible.
– 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.

Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the

and keep it depressed.
To lock the pressed On/Off switch 1, slide the
On/Off switch 1 toward the rear.
To switch off the power tool, release the On/Off
switch 1, or when it is locked, briefly press the
On/Off switch 1 and then release it.

Working Advice

Saw Blades and Saw Blade Guides
Depending on the material thickness to be
worked, various saw blade guides and the corre-
sponding saw blades can be used. See the Acces-
sories Overview for more details.
Base Plate
The foam rubber cutter can be used with or with-
out the base plate. The base plate is equipped
with rollers, and allows for easy and right-angled
guidance of the cutter.
For cutting random forms and for cutouts, it is
recommended to work without the base plate.
Cutting Foam
For precise cuts, especially with soft foams and
similar materials, work only with moderate feed.
To not press the material together or squeeze it
apart too excessively while working.
Dismount the base plate for smaller cutouts.
Puncture the material using a knife or a pair of
scissors, then insert the saw blade guide into the
opening und work the cutout.
