Dust/Chip Extraction

f Before any work on the machine itself, pull

the mains plug.

Mounting the Extraction Adapter (see figure F)

Attach the extraction adapter 27 onto the sawdust

ejector 16 until it latches. A vacuum hose with a diam-

eter of 35 mm can be connected to the extraction

adapter 27.

f The extraction adapter may not be mounted

when no external dust extraction is con-

nected. Otherwise the extraction channel can

become clogged.

f Do not connect a dust bag to the extraction

adapter. Otherwise the extraction system can

become clogged.

To ensure optimum extraction, the extraction adapter

27 must be cleaned regularly.

External Dust Extraction

Connect the vacuum hose 31 to a vacuum cleaner

(accessory). An overview for connecting to various

vacuum cleaners can be found at the end of this man-

ual.

The machine can be plugged directly into the recep-

tacle of a Bosch all-purpose vacuum cleaner with

remote starting control. The vacuum cleaner starts

automatically when the machine is switched on.

The vacuum cleaner must be suitable for the material

being worked.

When vacuuming dry dust that is especially detrimen-

tal to health or carcinogenic, use a special vacuum

cleaner.

Operation

Operating Modes

f Before any work on the machine itself, pull

the mains plug.

Adjusting the Cutting Depth (see figure C)

f 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 24. 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

plate 14. Adjust the desired cutting depth at the cut-

ting -depth scale. Tighten the clamping lever 24 again.

The tightening tension of the clamping lever 24 can be

readjusted. For this, unscrew the clamping lever 24,

and screw it back again turned offset by at least 30°

in anticlockwise direction.

Adjusting the Cutting Angle

It is best to place the machine on the face side of the

blade guard 17.

Loosen the wing bolts 7 and 15. Tilt the saw side-

wards. Adjust the desired measure on the scale 5.

Tighten the wing bolts 7 and 15 again.

Note: For bevel cuts, the cutting depth is smaller than

the setting indicated on the cutting-depth scale 25.

Cutting Marks

The 0° cutting mark (10) indicates the position of the

saw blade for right-angled cuts. The 45° cutting mark

(9) indicates the position of the saw blade for 45°

cuts.

For precise cuts, position the circular saw against the

workpiece as shown in the figure. It is best to carry out

a trial cut.

Starting Operation

f Observe correct mains voltage! The voltage

of the power 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.

Check the adjustment of the riving knife before start-

ing operation of the machine.

Switching On and Off

To start the machine, first push the lock-off button for

the On/Off switch 2 and then press the On/Off

switch 1 and keep it pressed.

To switch off the machine, release the On/Off switch

Note: For safety reasons, the On/Off switch 1 cannot

be locked; it must remain pressed during the entire

operation.
