the mains plug.
When mounting the saw blade, wear protec-
tive gloves. Danger of injury when touching the
saw blade.
Only use saw blades that correspond with the
characteristic data given in the operating
instructions.
Do not under any circumstances use grinding
discs as the cutting tool.
Selecting a Saw Blade
An overview of recommended saw blades can be found
at the end of this manual.
Removal of the Saw Blade (see figure A)
For changing the cutting tool, it is best to place the
power tool on the face side of the motor housing.
• Press the spindle lock button 5 and keep it pressed.
The spindle lock button 5 may be actuated
only when the saw spindle is at a standstill.
Otherwise, the power tool can be damaged.
• With the Allen key 17, unscrew the clamping bolt 18
turning in rotation direction
• Tilt back the retracting blade guard 12 and hold
firmly.
• Remove the clamping flange 19 and the saw blade
20 from the saw spindle 22.
Mounting the Saw Blade (see figure A)
For changing the cutting tool, it is best to place the
power tool on the face side of the motor housing.
• Clean the saw blade 20 and all clamping parts to be
assembled.
• Tilt back the retracting blade guard 12 and hold
firmly.
• Place the saw blade 20 on to the mounting flange
21. The cutting direction of the teeth (direction or
arrow on saw blade) and the direction-of-rotation
arrow on the blade guard 1 must correspond.
• Mount the clamping flange 19 and screw in the
clamping bolt 18 turning in rotation direction
Observe correct mounting position of mounting
flange 21 and clamping flange 19.
• Press the spindle lock button 5 and keep it pressed.

Dust/Chip Extraction
Before any work on the power tool itself, pull
the mains plug.
Mounting the Extraction Adapter (see figure B)
Attach the extraction adapter 24 onto the sawdust
ejector 16 until it latches. Secure the extraction adapter
24 additionally with the screw 23.
A vacuum hose with a diameter of 35 mm can be con-
nected to the extraction adapter 24.
The extraction adapter may not be mounted
when no external dust extraction is con-
nected. Otherwise the extraction channel can
become 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
24 must be cleaned regularly.
External Dust Extraction
Connect the vacuum hose 30 to a vacuum cleaner
(accessory). An overview for connecting to various vac-
uum cleaners can be found at the end of this manual.
The machine can be plugged directly into the recepta-
cle of a Bosch all-purpose vacuum cleaner with remote
starting control. The vacuum cleaner starts automati-
.
cally when the machine is switched on.
The vacuum cleaner must be suitable for the material
being worked.
When vacuuming dry dust that is especially detrimental
to health or carcinogenic, use a special vacuum cleaner.
Operation
Operating Modes
Before any work on the power tool itself, pull
the mains plug.
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 workpiece.
Loosen the clamping lever 25. For a smaller cutting
depth, pull the saw away from the base plate 14; for a
larger cutting depth, push the saw toward the base
. The tightening
plate 14. Adjust the desired cutting depth at the cut-
ting-depth scale. Tighten the clamping lever 25 again.
The tightening tension of the clamping lever 25 can be
readjusted. For this, unscrew the clamping lever 25,
and screw it back again turned offset by at least 30° in
counterclockwise direction.
