SAFETy INSTRuCTIONS
FOR ALL SAwS
CUTTInG PrOCEDUrES
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 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.

Kickback causes and related warnings
- 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) Maintain a firm grip on the saw and
position your arm 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,
center the saw blade in the kerf and check
that saw teeth are not engaged into the
material.
If saw blade is binding, it may walk
up or kickback from the workpiece as the saw
is restarted.
d) Support large panels to minimize the risk
of blade pinching and kickback. Large
panels tend to sag under their own weight.
Supports must be placed under the panel on
both sides, near the line of cut and near the
edge of the panel.
e) Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
f) Blade depth and bevel adjusting locking
levers must be tight and secure before
making cut.
If blade adjustment shifts while
cutting, it may cause binding and kickback.
g) Use extra caution when making a “plunge
cut” into existing walls or other blind
areas.
The protruding blade may cut objects
that can cause kickback.
