DeWalt DCS570 Manual page 15

NOTICE: Never engage the blade lock while saw is
running, or engage in an effort to stop the tool. Never
turn the saw on while the blade lock is engaged. Serious
damage to your saw will result.
To Replace the blade (Fig. C, D)
1. Remove the battery.
2. To loosen the blade clamping screw
lock 11 and turn the saw spindle with the blade wrench
14 , stored underneath the battery compartment, until
the blade lock engages and the blade stops rotating.
With the blade lock engaged, turn the blade clamping
screw counterclockwise with the blade wrench (screw has
right-hand threads and must be turned counterclockwise
to loosen).
3. Remove the blade clamping screw
washer 16 . Remove old blade.
4. Clean any sawdust that may have accumulated in the
guard or clamp washer area and check the condition and
operation of the lower blade guard as previously outlined.
Do not lubricate this area.
5. Select the proper blade for the application (refer to Blades).
Always use blades that are the correct size (diameter)
with the proper size and shape center hole for mounting
on the saw spindle. Always assure that the maximum
recommended speed (rpm) on the saw blade meets or
exceeds the speed (rpm) of the saw.
6. Follow steps 1 through 5 under To Install the Blade, making
sure that the blade will rotate in the proper direction.
Lower Blade Guard

WARNING: The lower blade guard is a safety feature
that reduces the risk of serious personal injury. Never
use the saw if the lower guard is missing, damaged,
misassembled or not working properly. Do not rely
on the lower blade guard to protect you under all
circumstances. Your safety depends on following
all warnings and precautions as well as proper
operation of the saw. Check the lower blade guard
for proper closing before each use. If the lower blade
guard is missing or not working properly, have the
saw serviced before using. To assure product safety
and reliability, repair, maintenance and adjustment
should be performed by an authorized service center
or other qualified service organization, always using
identical replacement parts.
Checking the Lower Guard (Fig. A)
1. Turn tool off and disconnect from power supply.
2. Rotate the lower guard lever (Fig. A,
position to the fully open position.
3. Release the lever and observe the guard
fully closed position.
The tool should be serviced by a qualified service center if it:
• fails to return to the fully closed position,
• moves intermittently or slowly, or

7 return to the
• contacts the blade or any part of the tool in all angles and
depth of cut.
Blades

WARNING: To minimize the risk of eye injury, always
use eye protection. Carbide is a hard but brittle material.
Foreign objects in the workpiece such as wire or nails
can cause tips to crack or break. Only operate saw when
proper saw blade guard is in place. Mount blade securely
in proper rotation before using, and always use a clean,
sharp blade.

WARNING: Do not cut metal, plastic, concrete, masonry
or fiber cement materials with this saw.

Kickback
Kickback is a sudden reaction to a pinched, bound or misaligned
saw blade, causing an uncontrolled saw to lift up and out of the
workpiece toward the operator. When the blade is pinched or
bound tightly by the kerf closing down, the blade stalls and the
motor reaction drives the unit rapidly back toward the 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 base plate
to support the blade and minimizes twisting and
