Further Safety Instructions For All Saws; Kickback Causes And Related Warnings - Dremel 670 Original Instructions Manual

b. Do not reach underneath the workpiece. The guard cannot protect
you from the blade below the workpiece.
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
workpiece.
d. Never hold the workpiece in your hands or across your leg while
cutting. Secure the workpiece to a stable platform. lt is important to
support the work properly to minimise body exposure, blade binding, or
loss of control.
e. Hold the 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 could give the operator
an electric shock.
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 off-centre, 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.

KICKBACK CAUSES AND RELATED WARNINGS

• Kickback is a sudden reaction to a pinched, jammed 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 jammed 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
