1. Secure the guide rail from below with two screw
clamps.
NOTE The saw must be placed on the guide rail in
the area before the workpiece.
2. CAUTION Take care to ensure that the saw blade
is not in contact with the workpiece.
Place the saw on the guide rail in the saw mounting
area of the rail (a short distance before the starting
point of the cut).
3. Switch the power tool on.
4. Push the saw steadily across the workpiece.
The pivoting guard opens as it contacts the actu-
ating edge at the side of the guide rail and sub-
sequently closes at the end of the rail as the cut is
completed.
7.8 Using the saw with a dust and chip removal
system
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.
