Assembly
 Before any work on the machine itself, pull the mains
plug.
Mounting the Saw Blade Guide (see figure A)
Remove the screws 6 from the housing. Attach the saw blade
guide 2 onto the housing in such a manner that the mounting
pins engage into the corresponding holes and secure with the
screws 6.
Inserting/Replacing Saw Blades (see figure B)
 Wear protective gloves when mounting the saw blades.
Danger of injury when touching the saw blades.
Loosen and remove the knurled screws 8 together with the
spring washers and the cover plate 7.
 Firstly, insert the saw blade pair 3 into the bottom of the
saw blade guide 2, paying attention 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 7 onto the set screws on the housing and
secure them with the knurled screws 8, ensuring that the
spring washers have also been mounted.
Mounting the Base Plate (see figure C)
Insert the saw blade guide 2 into the corresponding notch on
the base plate 4. Tighten the tensioning screw 9.
Dust/Chip Extraction
 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Operation
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On and Off
To switch on the power tool, press the On/Off switch 1 and
keep it pressed.
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.
To save energy, only switch the power tool on when using it.
Working Advice
 Before any work on the machine itself, pull the mains
plug.
Saw Blades and Saw Blade Guides
Depending on the material thickness to be worked, various
saw blade guides and the corresponding saw blades can be
used. See the Accessories Overview for more details.
Base Plate
The foam rubber cutter can be used with or without 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 mate-
rials, 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 ma-
terial using a knife or a pair of scissors, then insert the saw
blade guide into the opening und work the cutout.
For larger cutouts, select an entry opening large enough to in-
sert the saw blade guide with the mounted base plate. Pay at-
tention that no obstacles are on the bottom of the material.
Guide the power tool with moderate pressure alongside the
cutout line.
Maintenance and Service
Maintenance and Cleaning
 Before any work on the machine itself, pull the mains
plug.
 For safe and proper working, always keep the machine
and ventilation slots clean.
The saw blade guide and the saw blades at regular intervals,
approx. after 8 hours of operation. Remove the saw blades
from the power tool for this and preferably clean the saw
blades with petrol. If required, use a scraper to clean the saw
blade guide. Apply a light coat of oil onto the saw blade guide
before assembling new or resharpened saw blades.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
