EnGLIsH
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 base plate 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
blade angle to the base plate 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.
46
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
2. To obtain the correct depth of cut, align the appropriate
mark on the depth adjustment strap
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
may loosen in time and hit the base plate before tighten ing.
To Tighten the Lever:
1. Hold depth adjustment lever
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
1. Raise the bevel adjustment lever
2. Tilt the base plate to the desired angle by aligning the fine
bevel pointer 22 with the desired angle mark on the pivot
bracket 21 .
3. Lower the bevel adjustment lever to retighten.
Bevel Detent (Fig. A, G)
The DCS570 is equipped with a bevel detent feature. As you
tilt the base plate 5 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
desire another angle, continue tilting the base plate until the
coarse bevel pointer 23 or the fine pointer
desired mark.
