 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Note: While sawing, always use the deflection tube 24 or the
dust/chip box 25 so that you will not be hit by thrown about
chips.
The deflection tube 24 can be used with or without dust/chip
extraction. Depending on the application, turn the deflection
tube 24 in such a manner that you are not hit by chips and in-
sert it firmly into the sawdust ejector 16.
External Dust Extraction (see figure B)
Mount the vacuum hose 23 (accessory) on to the chip ejector
16. Connect the vacuum hose 23 to a vacuum cleaner (acces-
sory). An overview for connecting to various vacuum cleaners
can be found at the end of this manual.
The machine can be plugged directly into the receptacle of a
Bosch all-purpose vacuum cleaner with remote starting con-
trol. The vacuum cleaner starts automatically when the ma-
chine 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.
Integrated Dust Extraction (see figures C–E)
For smaller jobs, the dust/chip box 25 can be used with the
slider 26 shut. For larger jobs, the slider 26 should be open so
that the chips can fall out.
Insert the dust/chip box 25 firmly into the chip ejector 16.
Empty the dust/chip box 25 in time to maintain optimum effi-
ciency.
To empty the dust/chip box 25, pull it off of the chip ejector
16. Press the slider 26 upward, turn the dust/chip box 25
aside and empty it.
Before reattaching, clean the connection sleeve of the
dust/chip box 25.
Operation

Operating Modes

 Before any work on the machine itself, pull the mains
plug.
Adjusting the Cutting Depth (see figure F)
 Adjust the cutting depth to the thickness of the work-
piece. Less than a full tooth of the blade teeth should be
visible below the workpiece.
Loosen the clamping lever 27. For a smaller cutting depth,
pull the saw away from the base plate 12; for a larger cutting
depth, push the saw toward the base plate 12. Adjust the de-
sired cutting depth at the cutting-depth scale. Tighten the
clamping lever 27 again.
Adjusting the Cutting Angle
Loosen the wing bolts 7 and 14. Tilt the saw sidewards. Ad-
just the desired measure on the scale 5. Tighten the wing
bolts 7 and 14 again.
Note: For bevel cuts, the cutting depth is smaller than the set-
ting indicated on the cutting-depth scale 28.

Cutting Marks (see figure G)
(PKS 55 A/PKS 55-2 A/PKS 66 A/PKS 66 AF/
PKS 66-2 AF)
The "CutControl" 9 viewing window, which folds out to the
front, is used for precise guiding of the circular saw alongside
the cutting line on the workpiece. The "CutControl" 9 viewing
window has a mark each for right-angled cuts and for 45°
cuts.
The 0° cutting mark 30 indicates the position of the saw blade
for right-angled cuts. The 45° cutting mark 29 indicates the
position of the saw blade for 45° cuts.
For precise cuts, position the circular saw against the work-
piece as shown in the figure. It is best to carry out a trial cut.

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 start the machine, first push the lock-off button for the
On/Off switch 1 and then press the On/Off switch 2 and keep
it pressed.
To switch off the machine, release the On/Off switch 2.
Note: For safety reasons, the On/Off switch 2 cannot be
locked; it must remain pressed during the entire operation.
To save energy, only switch the power tool on when using it.
