Mounting the Extraction Adapter

(see figure B)

Attach the extraction adapter 22 onto the saw-

dust ejector 14 until it latches. A vacuum hose

with a diameter of 35 mm can be connected to

the extraction adapter 22.

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 22 must be cleaned regularly.

External Dust Extraction

Connect the vacuum hose 30 to a vacuum clean-

er (accessory). 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 re-

ceptacle of a Bosch all-purpose vacuum cleaner

with remote starting control. The vacuum clean-

er starts automatically when the machine is

switched on.

The vacuum cleaner must be suitable for the ma-

terial being worked.

When vacuuming dry dust that is especially det-

rimental 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 work-

piece.

Loosen the clamping lever 23. For a smaller cut-

ting 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 23 again.

If the cutting depth cannot be fully adjusted af-

ter loosening clamping lever 23, pull clamping

lever 23 away from the saw and swivel it down-

ward. Release the clamping lever 23 again. Re-

peat this procedure until the requested cutting

depth can be adjusted.

If the cutting depth cannot be sufficiently locked

after tightening clamping lever 23, pull clamping

lever 23 away from the saw and swivel it up-

ward. Release the clamping lever 23 again. Re-

peat this procedure until the cutting depth is

locked.

Adjusting the Cutting Angle

Loosen the wing bolts 6 and 25. Tilt the saw

sidewards. Adjust the desired measure on the

scale 5. Tighten the wing bolts 6 and 25 again.

Note: For bevel cuts, the cutting depth is small-

er than the setting indicated on the cutting-

depth scale 24.

Cutting Marks

The 0° cutting mark (9) indicates the position of

the saw blade for right-angled cuts. The 45° cut-

ting mark (8) 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.
