Mounting the Dust Extraction Port
(Fig. A, F, L)
Your DCS578/DCS579 circular saws are supplied with a dust
extraction port.
To Install Dust Extraction Port
1. Fully loosen depth adjustment lever
2. Place base plate 11 in the lowest position.
3. Align the left half of the dust extraction port
blade guard as shown. Be sure to insert the tab into the
15
casting notch on the tool. When installed correctly, it will
snap fully over the original depth of cut pointer.
4. Align the right-hand piece with the left.
5. Insert screws and tighten securely.
Guide Rail System (Fig. M)
DCS579
Guide rails, available in different lengths as accessories, allow
the use of the circular saw for precise, straight clean cuts and
simultaneously protect the workpiece surface against damage.
In conjunction with additional accessories, exact angled cuts,
mitre cuts and fitting work can be completed with the guide
rail system.
Clamps 37 are available to secure the guide rail
workpiece (Fig. M). Use of these clamps
36
guide rail 35 is securely attached to the workpiece
working. Once the guide rail is set to the cut line and securely
fixed to the workpiece, there is no movement during cutting.
iMPORTAnT: The height scale on the unit is set for using the
saw without a guide rail. When using the saw on the guide rail
the difference in height will be approximately 5.0 mm.
Setting the Circular Saw To the Guide
Rail (Fig. A, N)
The clearance between the circular saw and the guide rail
(Fig. N, 35 ) must be very small to achieve best cutting results.
The smaller this clearance the better the straight line finish will
be on the workpiece.
The clearance can be set with the two rail adjusters
(Fig. A) for each channel in the base for 0° cutting
1–45° bevel cutting . The rail adjusters are precision cams
20
that allow for the reduction of clearance between the unit
and guide rail. Once these adjusters have been set, sideways

nOTE: The adjusters are set to minimum clearance in the
factory and may need adjusting and setting before the unit is
used. Use the following instructions for setting the circular saw
to the guide rail.
REMEMBER: Set the rail adjusters on the saw to the guide rail.
1. Undo the screw inside the rail adjuster to allow for
adjustment between the saw and the guide rail.
2. Retract the lower guard and place the unit on the guide rail,
ensuring the blade is in the highest position.
3. Rotate the adjuster until saw locks on guide rail.
iMPORTAnT: Make sure the saw is securely attached to the
rail by trying to push the saw forward. Ensure there is no
movement of the saw.
4. Rotate the adjuster back slightly until saw slides easily along
the rail.
5. Hold the rail adjuster in position and tighten the
screw again.
nOTE: AlWAYS adjust the system for use with other rails.
The rail adjusters are now set up to minimise sideways deviation
when cutting with the saw on the guide rail.
Before using the saw, the anti-splinter guard
the guide rail will need tuning in. Refer to Tuning the
Anti-Splinter Guard.
Tuning the Anti-Splinter Guard (Fig. N)
The guide rail
that has to be tuned to the saw before the first use.
The anti-splinter guard
guide rail (Fig. N). The purpose of this anti-splinter guard is to
provide the user with a visible blade cut line while reducing
the chipping that occurs along the workpiece cut edge
during cutting.
iMPORTAnT: AlWAYS read and follow the Setting
the Circular Saw to the Guide Rail before cutting the
splinter guard!
for safe
Steps to Tune the Anti-Splinter Guard (Fig. O–R)
1. Place the guide rail
a minimum length of 100 mm overhanging the workpiece
(Fig. O). Use a clamp to ensure that the guide rail is securely
attached to the workpiece. This will ensure accuracy.
2. Set the unit to a 20 mm depth of cut.
3. Place the front of the saw on the overhang end of the guide
rail, making sure that the blade is positioned in front of the
rail edge (Fig. P).
4. Turn the saw on and slowly cut the splinter guard along the
full length of the rail in one continuous operation. The edge
of the splinter guard now corresponds exactly to the cutting
, 20 edge of the blade (Fig. Q).
and for
To tune in the anti-splinter guard on the other side of the guide
rail, remove the saw from the rail and rotate the rail 180°. Repeat
steps 1 through 4.
nOTE: If desired, the splinter guard can be bevelled to 45°, then
repeat steps 1 through 4. This allows one side of the rail for
