7.5 Sawing along a line
There is a cutting line indicator for straight cuts or bevel
cuts (0° and 45°) at the front section of the base plate of
the power tool. This permits precise cuts to be made at
the selected cutting angle. The edge of the line indicator
corresponds to the inside of the saw blade. The viewing
window provides a better view of the cutting line and thus
ensures a better cut. Additional cutting line indicators are
en
located at the front opening for the saw blade and at the
end of the base plate.
1. Secure the workpiece so that it cannot move.
2. Position the workpiece so that the saw blade is free
to move under the workpiece.
3. Check to ensure that the switch on the power tool
is in the off-position.
4. Fit the battery into the power tool.
5. Place the power tool with the base plate on the
workpiece in such a way that the blade still has no
contact with the workpiece.
6. Switch the power tool on by pressing the switch-on
interlock and then pressing the on/off switch while
the switch-on interlock is depressed, .
7. Guide the power tool along the cutting line on the
workpiece at a suitable speed.
7.6 Sawing using the parallel guide (accessory)
Use of the two-arm parallel guide allows precise cuts to
be made along the edge of the workpiece or, respectively,
strips of even width to be cut.
The parallel guide can be fitted on either side of the base
plate.
7.7 Fitting / adjusting the parallel guide 7
1. Pull the battery out of the power tool.
2. Release the clamping screws on the base plate.
3. Slide both arms of the parallel guide under the
clamping screws.
4. Set the desired cutting width.
5. Tighten the clamping screws.
7.8 Using the saw on the guide rail 8
7.8.1 Longitudinal cuts at 0 °
Place the saw on the guide rail so that the rib fits into the
groove in the base plate.
7.8.2 Longitudinal cuts at up to 50 °
Guide the saw so that the outer edge of the base plate
runs along the rib on the guide rail. The saw blade will
otherwise come into contact with the guide rail.
7.8.3 Cuts at an angle across the surface of the
workpiece
NOTE
The cutting angle indicated is the angle of deviation from
a straight, right-angled cut.
26
1. Position the guide rail with the zero mark at the edge
of the workpiece and then pivot the rail until the
desired angle shown on the angle scale is opposite
the zero mark.
2. Use the two screw clamps to secure the guide rail.
7.9 Trimming to size
1. Secure the guide rail from below with two screw
clamps.
NOTE The saw must be placed on the guide rail
behind the workpiece.
2. CAUTION Take care to ensure that the saw blade
is not in contact with the workpiece.
Position the saw on the guide rail a short distance
from the starting point of the cut.
3. Switch the power tool on.
4. Push the saw steadily across the workpiece.
The pendulum guard opens as it contacts the ac-
tuating edge at the side of the guide rail and sub-
sequently closes at the end of the rail as the cut is
completed.
7.10 Cleaning the chip ejector channel
CAUTION
The battery must not be inserted into the power tool.
1. Press the plastic tab at the rear underside of the
guard and remove the guard.
2. Clean the chip ejector channel in the guard.
3. Refit and secure the guard, making sure that the
plastic tab engages.
4. Check that moving parts on the power tool are work-
ing properly and not jamming. Check also whether
parts are broken or damaged in such a way that
impairs proper functioning of the power tool.
7.11 Using the saw with a dust and chip removal
system 9
NOTE
The circular saw is equipped with a hose connector
suitable for use with common types of vacuum cleaner
hose. In order to connect the vacuum cleaner hose to the
saw, use of a suitable adapter may be necessary.
CAUTION
Dusts are hazardous to the health and can cause respir-
atory or skin diseases and allergic reactions.
WARNING
Certain dusts are considered to be carcinogenic (cause
cancer). These include mineral dust as well as oak and/or
beech wood dust, particularly in conjunction with addi-
tional substances used for the treatment of wood (chro-
mate, wood preservatives).
