3.1.5 Service
a) Have your power tool serviced by a
replacement parts. This will ensure that the
safety of the power tool is maintained.
3.2 Safety instructions for all saws
a) DANGER: 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 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 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 the power tool only by the 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.
3.3 Additional safety instructions for all saws
• 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 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 the result of saw misuse and/or
incorrect operating procedures or conditions
and can be avoided by taking proper precautions
as given below.
a)
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
