DeWalt DCS573 - Kickback Prevention; Depth and Bevel Adjustments

ENGLISH
blade angle to the shoe and greater blade surface
in the material increase the chance for binding and
misalignment(twist) tooccur.
7. RESTARTING A CUT WITH THE BLADE TEETH JAMMED
AGAINST THE MATERIAL
a. The saw should be brought up to full operating speed
before starting a cut or restarting a cut after the unit has
been stopped with the blade in the kerf.Failure to do so
can cause stalling andkickback.
Any other conditions which could result in pinching,
binding, twisting, or misalignment of the blade could cause
kickback.Refer to the sections Further Safety Instructions for
All Saws and Blades for procedures and techniques that will
minimize the occurrence ofkickback.
Depth of Cut Adjustment(Fig.E, F)
1. Raise the depth adjustment lever
4
toloosen.
2. To obtain the correct depth of cut, align the appropriate
mark on the depth adjustment strap
30
with notch
31
on
the upper bladeguard.
3. Tighten the depth adjustmentlever.
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 FigureF. 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.E)
It may be desirable to adjust the depth adjustment lever
4
.It
may loosen in time and hit the shoe beforetighten ing.
To Tighten the Lever:
1. Hold depth adjustment lever
4
and loosen the locknut
32
.
2. Adjust the depth adjustment lever by rotating it in the
desired direction about 1/8 of arevolution.
3. Retightennut.
Bevel Angle Adjustment(Fig.A, G)
The bevel angle adjustment mechanism can be adjusted
between 0° and 57°.
To achieve better accuracy in cutting, use the fine adjustment
markings located on the pivot bracket
33
.
1. Raise the bevel adjustment lever
10
toloosen.
2. Tilt the shoe to the desired angle by aligning the fine bevel
pointer
35
with the desired angle mark on the pivot
bracket
33
.
3. Lower the bevel adjustment lever toretighten.
Bevel Detent(Fig.A, G)
The DCS573 is equipped with a bevel detent feature.As you
tilt the shoe
5
you will hear a click and feel the shoe stop
at both 22.5 and 45degrees.If either of these is the desired
angle, retighten the lever
10
by lowering it.If you desire
another angle, continue tilting the shoe until the coarse bevel
pointer
34
or the fine pointer
35
aligns with the desiredmark.
operator.If the blade becomes twisted or misaligned in the cut,
the teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to climb out of the kerf
and jump back toward theoperator.
Kickback is more likely to occur when any of the following
conditionsexists.
1. IMPROPER WORKPIECE SUPPORT
a. Sagging or improper lifting of the cut off piece can cause
pinching of the blade and lead tokickback.
b. Cutting through material supported at the outer ends
only can cause kickback.As the material weakens it sags,
closing down the kerf and pinching the blade(Fig.L).
c. Cutting off a cantilevered or overhanging piece of
material from the bottom up in a vertical direction
can cause kickback.The falling cut off piece can pinch
theblade.
d. Cutting off long narrow strips(as in ripping) can cause
kickback.The cut off strip can sag or twist closing the kerf
and pinching theblade.
e. Snagging the lower guard on a surface below the
material being cut momentarily reduces operator
control.The saw can lift partially out of the cut increasing
the chance of bladetwist.
2. IMPROPER DEPTH OF CUT SETTING ON SAW
a. To make the most efficient cut, the blade should protrude
only far enough to expose one‑half of a tooth as shown
in FigureF.This allows the shoe to support the blade and
minimizes twisting and pinching in the material.See the
section titled Depth of CutAdjustment.
3. BLADE TWISTINGMISALIGNMENT IN CUT
a. Pushing harder to cut through a knot, a nail or a hard
grain area can cause the blade totwist.
b. Trying to turn the saw in the cut(trying to get back on
the marked line) can cause bladetwist.
c. Overreaching or operating the saw with poor body
control(out of balance), can result in twisting theblade.
d. Changing hand grip or body position while cutting can
result in bladetwist.
e. Backing up the saw to clear blade can lead totwist.
4. MATERIALS THAT REQUIRE EXTRA ATTENTION
a. Wet timber
b. Green timber(material freshly cut or not kiln dried)
c. Pressure treated timber(material treated with
preservatives or anti‑rot chemicals)
5. USE OF DULL OR DIRTY BLADES
a. Dull blades cause increased loading of the saw.To
compensate, an operator will usually push harder which
further loads the unit and promotes twisting of the blade
in the kerf.Worn blades may also have insufficient body
clearance which increases the chance of binding and
increasedloading.
6. LIFTING THE SAW WHEN MAKING A BEVEL CUT
a. Bevel cuts require special operator attention to proper
cutting techniques – especially guidance of the saw.Both
