Prior To Operation - DeWalt DCS579N Original Instructions Manual

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 is equipped with an anti‑splinter guard
35
that has to be tuned to the saw before the first use.
The anti‑splinter guard 38
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!
Steps to Tune the Anti-Splinter Guard (Fig. O–R)
1. Place the guide rail 35
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
edge of the blade (Fig. Q).
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
cutting parallel cuts and the other side of the rail is tuned in for
45° bevel cuts (Fig. R).
nOTE: If the anti‑splinter guard is tuned in for parallel cutting
on both sides, then when the unit is bevelled, the blade will not
run true to the edge of the anti‑splinter guard. This is because
the pivot point of the unit bevel is not stationary and the blade
moves out over when the unit is bevelled.

is situated on each edge of the
on a scrap piece of wood 39
Kerf Indicator (Fig. S–U)
The front of the saw shoe has a kerf indicator
and bevel cutting. This indicator enables you to guide the saw
along cutting lines penciled on the material being cut. The kerf
indicator lines up with the left (outer) side of the saw blade,
which makes the slot or "kerf" cut by the moving blade fall to
the right of the indicator. Guide along the penciled cutting line
so that the kerf falls into the waste or surplus material. Fig. T
shows the saw in the parallel cutting position relative to the
guide rail. Fig. U shows the saw in the bevel cutting position
relative to the guide rail.

Prior to Operation

• Make sure the guards have been mounted correctly. The
saw blade guard must be in closed position.
• Make sure the saw blade rotates in the direction of the
arrow on the blade.
• Do not use excessively worn saw blades.
