Maintenance - DeWalt DCS578 Instruction Manual

The kerf indicator lines up with the left (inner) 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.
Workpiece Support (Fig. M–O)

WARNING: It is important to support the work properly
and to hold the saw firmly to prevent loss of control which
could cause personal injury. Figure M illustrates proper hand
support of the saw. Maintain a firm grip with both hands
on the saw and position your body and arm to allow you to
resist kickback if it occurs. ALWAYS TURN OFF TOOL AND
REMOVE BATTERY BEFORE MAKING ANY ADJUSTMENTS!
Figure M shows proper sawing position. Note that hands
are kept away from cutting area. To avoid kickback, DO
support board or panel NEAR the cut (Fig. N). DON'T support
board or panel away from the cut (Fig. O).
Place the work with its "good" side – the one on which
appearance is most important – down. The saw cuts
upward, so any splintering will be on the work face that is
up when you cut it.
Cutting (Fig. N)
Place the wider portion of the saw shoe on that part of the
workpiece which is solidly supported, not on the section
that will fall off when the cut is made. As an example,
Figure N illustrates the RIGHT way to cut off the end of a
board. Always clamp work. Don't try to hold short pieces by
hand! Remember to support cantilevered and overhanging
material. Use caution when sawing material from below.
Be sure saw is up to full speed before blade contacts
material to be cut. Starting saw with blade against material
to be cut or pushed forward into kerf can result in kickback.
Push the saw forward at a speed which allows the blade to
cut without laboring.
Hardness and toughness can vary even in the same piece of
material, and knotty or damp sections can put a heavy load
on the saw. When this happens, push the saw more slowly,
but hard enough to keep working without much decrease
in speed. Forcing the saw can cause rough cuts, inaccuracy,
kickback, and over-heating of the motor.
Should your cut begin to go off the line, don't try to force
it back on. Release the trigger switch and allow blade to
come to a complete stop. Then you can withdraw the saw,
sight anew, and start a new cut slightly inside the wrong
one. Withdraw the saw if you must shift the cut. Forcing
a correction inside the cut can stall the saw and lead
to kickback.
IF SAW STALLS, RELEASE THE TRIGGER SWITCH AND
BACK THE SAW UNTIL IT IS LOOSE. BE SURE BLADE IS
STRAIGHT IN THE CUT AND CLEAR OF THE CUTTING EDGE
BEFORE RESTARTING.
As you finish a cut, release the trigger switch and allow the
blade to stop before lifting the saw from the work. As you
lift the saw, the spring-tensioned lower blade guard will
automatically close under the blade. Remember the blade
is exposed until this occurs. Never reach under the work for
any reason. When you have to retract the lower blade guard
manually (as is necessary for starting pocket cuts), always
use the retracting lever.

WARNING: When cutting thin strips, be careful to ensure
that small cutoff pieces don't hang up on the inside of the
lower blade guard.
Ripping (Fig. P)
Ripping is the process of cutting wider boards into narrower
strips – cutting grain lengthwise. Hand guiding is more
difficult for this type of sawing and the use of a D
fence is recommended.
Pocket Cutting (Fig. Q)

WARNING: Never tie the lower blade guard in a raised
position. Never move the saw backwards when pocket
cutting. This may cause the saw to raise up off the work
surface, which could cause injury.
A pocket cut is one that is made in a floor, wall or other
flat surface.
1. Adjust the saw shoe so the blade cuts at desired depth.
2. Tilt the saw forward and rest front of the shoe on
material to be cut.
3. Using the lower blade guard retracting lever, retract the
lower blade guard to an upward position. Lower the rear of
the shoe until the blade teeth almost touch the cutting line.
4. Release the lower blade guard (its contact with the work
will keep it in position to open freely as you start the cut).
Remove your hand from the lower blade guard retracting
lever and firmly grip the auxiliary handle
Figure Q. Position your body and arm to allow you to resist
kickback if it occurs.
5. Make sure blade is not in contact with cutting surface
before starting saw.
6. Start the motor and gradually lower the saw until its shoe
rests flat on the material to be cut. Advance saw along the
cutting line until cut is completed.
7. Release the trigger switch and allow the blade to stop
completely before withdrawing the blade from the material.
8. When starting each new cut, repeat the above steps.
Hang Hook (Fig. A)

WARNING: To reduce the risk of serious personal injury,
do not use the tool's hang hook to hang the tool from your
body. DO NOT use the hang hook for tethering or securing the
tool to a person or object during use. DO NOT suspend tool
overhead or suspend objects from the hang hook.

WARNING: To reduce the risk of injury from the circular
saw falling on operators or bystanders, make sure it is
supported securely when using the hang hook, or resting in
a secure and stable location when not in use. Be sure to keep
the area below clear to reduce the risk of the tool or off-cut
material falling and striking someone or something below.
The circular saw has a convenient hang hook
allows it to hang on a suitable, stable structure between
uses. The hang hook is not for tethering or securing the tool
to a person or object during use when elevated.

MAINTENANCE


WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can
cause injury.
Your D WALT power tool has been designed to operate
e
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper
tool care and regular cleaning.
Cleaning

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk of eye
