Safety Instructions For All Saws; Service; Causes And Operator Prevention Of Kickback - DeWalt DWS535 Instruction Manual

5) SERVICE
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
Safety Instructions for All Saws
DANGER:
a) Keep hands away from cutting area and the blade. Keep
your second hand on auxiliary handle or motor housing.
If both hands are holding the saw, they cannot be cut by the
blade.
b) Do not reach underneath the workpiece. The guard cannot
protect you from the blade below the workplace.
c) Adjust the cutting depth to the thickness of the workpiece.
Less than a full tooth of the blade teeth should be visible
below the workplace.
d) Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable platform. It
is important to support the work properly to minimize body
exposure, blade binding, or loss of control.
e) Hold power tool by insulated gripping surfaces when
performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a "live"
wire will also make exposed metal parts of the power tool
"live" and shock the operator.
f) When ripping always use a rip fence or straight edge
guide. This improves the accuracy of cut and reduces the
chance of blade binding.
g) Always use blades with correct size and shape (diamond
versus round) of arbour holes. Blades that do not match
the mounting hardware of the saw will run eccentrically,
causing loss of control.
h) Never use damaged or incorrect blade washers or bolt.
The blade washers and bolt were specially designed for your
saw, for optimum performance and safety of operation.
CAUSES AND OPERATOR PREVENTION OF 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 workplace 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 the result of saw misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
a) Maintain a firm grip with both hands on the saw and
position your arms to resist kickback forces. Position
your body to either side of the blade, but not in line with
the blade. Kickback could cause the saw to jump backwards,
but kickback forces can be controlled by the operator, if
proper precautions are taken.
b) When blade is binding, or when interrupting a cut for any
reason, release the trigger and hold the saw motionless
in the material until the blade comes to a complete
stop. Never attempt to remove the saw from the work or
pull the saw backward while the blade is in motion or
kickback may occur. Investigate and take corrective actions
to eliminate the cause of blade binding.
c) When restarting a saw in the workpiece, centre the saw
blade in the kerr and check that saw teeth are not engaged
