Hilti SCW 70 Original Operating Instructions page 27

The parallel guide can be fitted on either side of the base
plate.
6.6 Fitting / adjusting the parallel guide 6
1. Disconnect the supply cord plug from the power
outlet.
2. Slide the rip fence guide under the clamping screw.
3. Set the desired cutting width.
4. Tighten the clamping screw.
6.7 Using the saw on the guide rail 7
NOTE
Using the saw on the guide rail can reduce the risk of
kickback.
6.7.1 Inserting / removing the tool from the guide
rail adapter
1. Remove the rip fence, if one is fitted.
2. Fit the front edge of the base plate into the front
retaining lugs on the guide rail adapter.
3. Swing the rear edge of the base plate down fully
into the guide rail adapter.
The base plate must engage fully with the rear
retaining lug.
4. To remove the tool, pull the rear retaining lug back
slightly and lift the tool up out of the guide rail
adapter.
6.7.2 Longitudinal cuts at 0 °
Place the saw on the guide rail so that the rib fits into the
groove in the adapter.
6.7.3 Longitudinal cuts at up to 56 °
Guide the saw so that the outer edge of the guide rail
adapter runs along the rib on the guide rail. The saw
blade will otherwise come into contact with the guide rail.
6.7.4 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.
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.
6.8 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.
6.9 Cleaning the chip ejector channel 8
CAUTION
Ensure that the power tool is disconnected from the
electric supply.
1. Remove the screw at the rear underside of the
guard and then remove the vacuum cleaner hose
connector.
2. Clean the chip deflector and hose connector.
3. Refit the hose connector to the chip deflector and
secure it with the screw.
4. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may
affect the power tool's operation.
6.10 Using the saw with a dust and chip removal
system
NOTE
The circular saw is equipped with a hose connector
suitable for use with conventional vacuum cleaner hoses
with a diameter of 27 mm. 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).
CAUTION
Wherever possible, use a suitable mobile vacuum
dust removal system such as the WVC 40‑M (wood)
or VCU 40‑M (wood and mineral materials) for the
application concerned. Use a respiratory protector of
the P2 filter class with half-mask facepiece if no dust
removal system is available or its use is impossible.
In addition, to keep the concentration of dust low,
always ensure good ventilation.
CAUTION
Commercial and industrial users must consult the re-
sponsible trade association to clarify the situation re-
garding special requirements applicable to working on
other materials.
