Sawing using the guide rail
The guide rail is designed for making precise mitre cuts
at up to 45° and cuts across the surface of the work-
piece at angles of up to 60°. The guide rail must be in
faultless condition in order to ensure good results. The
non-slip strips located on the underside prevent the
rail slipping out of position and also protect the sur-
face of the workpiece. It is, however, recommended
that screw clamps are used to secure the guide rail. All
parts are manufactured from materials which ensure
smooth operation. The cut is made approx. 1 mm from
the edge of the rail at all angle settings. Use of the guide
rail reduces the set cutting depth by approx. 5 mm.
The tool must be placed on the guide rail so that the
rail profile and the channel in the baseplate of the tool
correspond and thus provide a smooth guide. Two
adjustable play compensators are provided on the base-
plate of the circular saw. These can be used to adjust
play between the circular saw and the guide rail, thus
ensuring optimum guidance.
Cutting / trimming
●
Use two screw clamps fitted from below to attach
the rail so that the section of the rail for positioning the
tool projects beyond the workpiece.
●
Position the tool on the corresponding section of
the guide rail and ensure that the saw blade is not in
contact with the workpiece.
●
Switch the tool on and slide it evenly towards the
workpiece. The pivoting guard opens when it contacts
the edge of the rail and closes again when the saw is
pushed off the far end of the guide rail.
Cuts at an angle across the surface of the workpiece
●
Position the guide rail with the zero mark at the edge
of the workpiece and pivot the rail until the desired
angle shown on the angle scale is opposite zero.
●
Use two screw clamps to secure the guide rail in this
position and then make the cut as described above.
The cutting angle indicated is the angle of deviation
from a straight, right-angled cut.
Plunge cutting
●
Use two screw clamps to fasten the guide rail to the
workpiece.
●
Lock the tool at the maximum cutting height posi-
tion and use the manual control to open the pivoting
guard.
●
Place the tool on the guide rail, taking care to ensure
that the baseplate lies flat on the rail.
●
Use the stop piece to increase safety when making
the plunge cut. It should be fixed in position at the rear
edge of the baseplate so that the rear plunge cut mark
on the circular saw coincides with the point at which
the cut is to begin.
●
Set the cutting depth to maximum depth unless a
pre-defined cutting depth is required.
●
Switch the tool on and plunge the blade evenly into
the workpiece.
External dust and chip extraction
Extraction of dust and chips reduces the amount of
dust in the working environment and helps to keep the
workplace clean. Connect the external extraction sys-
tem when you are using the saw for a long period or
when working with materials which produce harmful
dust when cut. The hand-held circular saw is equipped
with a hose connector suitable for use with conven-
tional extraction hoses with a diameter of
≥
27 mm.
The direction of chip ejection can be selected simply
by turning the pivoting chip ejector until it engages in
the desired position.
Cleaning the chip ejection channel
●
Ensure that the tool is disconnected from the mains
socket.
●
Press the plastic tab on the rear lower side of the
guard and remove the guard.
●
Clean the chip ejection channel in the guard and than
replace the guard, ensuring that the plastic tab is
engaged.
●
Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may
affect the power tool’s operation.
Ensure that only a safety vacuum cleaner of the “M”
class (wood) is used and that its equipment is of the
anti-static type. We recommend use of the Hilti WVC
40-M safety vacuum cleaner.
