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 35 to the
workpiece 36 (Fig. M). Use of these clamps 37 ensure that the
guide rail 35 is securely attached to the workpiece 36 for safe
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
19 , 20
(Fig. A) for each channel in the base for 0 ° cutting 19 and for
1–45 ° bevel cutting
20
. The rail adjusters are precision cams
that allow for the reduction of clearance between the unit
and guide rail. Once these adjusters have been set, sideways
movement of the saw during cutting is kept to a minimum
while allowing a smooth cutting action.
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.
Mounting and Adjusting the Parallel Fence
(Fig. K)
The parallel fence 33 is used for cutting parallel to the edge of
the workpiece.
Mounting
1. Slacken the parallel fence adjustment knob
32
to allow the
parallel fence to pass.
2. Insert the parallel fence 33 in the base plate 11 as shown.
3. Tighten the parallel fence adjustment knob 32 .
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 25 .
2. Place base plate 11 in the lowest position.
3. Align the left half of the dust extraction port 34 over upper
blade guard 15 as shown. Be sure to insert the tab into the
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.
Adjusting
1. Slacken the fence adjustment knob 32 and set the parallel
fence 33 to the desired width. The adjustment can be read
on the parallel fence scale.
2. Tighten the fence adjustment knob 32 .
Cut Length Indicator (Fig. J)
The markings on the side of the base plate 11 show the length
of the slot being cut into the material at the full depth of the cut.
The markings are in increments of 5 mm.
Bevel Detent (Fig. I)
The DCS578 and DCS579 are equipped with a bevel detent
feature. As you tilt the base plate you will hear a click and feel
the base plate stop at both 22.5 and 45 degrees. If either of
these is the desired angle, retighten the lever
8
by lowering it.
If you desire another angle, continue tilting the base plate until
the coarse bevel pointer
31 or the fine pointer 30 aligns with
the desired mark.
Bevel Angle Adjustment (Fig. A, I)
The bevel angle adjustment mechanism
9
can be adjusted
between 0 ° and 57 °.
To achieve better accuracy in cutting, use the fine adjustment
markings located on the pivot bracket
29 .
1. Raise the bevel adjustment lever 8 to loosen.
2. Tilt the base plate to the desired angle by aligning the fine
bevel pointer 30 with the desired angle mark on the pivot
bracket 29 .
3. Lower the bevel adjustment lever to retighten.
4. For the most efficient cutting action using a carbide tipped
saw blade, set the depth adjustment so that about one half
of a tooth projects below the surface of the wood to be cut.
5. A method of checking for the correct cutting depth is
shown in Fig. H. Lay a piece of the material you plan to cut
along the side of the blade, as shown in the Figure, and
observe how much tooth projects beyond the material.
Adjusting Depth Adjustment Lever (Fig. G)
It may be desirable to adjust the depth adjustment lever 25 . It
may loosen in time and hit the base plate before tighten ing.
To Tighten the lever
1. Hold depth adjustment lever
25
and loosen the
locknut 28 .
2. Adjust the depth adjustment lever by rotating it in the
desired direction about 1/8 of a revolution.
3. Retighten nut.
