performed. Use of the power tool for operations
different from those intended could result in a
hazardous situation.
h) Keep handles and grasping surfaces dry,
clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for
safe handling and control of the tool in unexpected
situations.
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
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 workpiece in your hands or
across your leg while cutting. Secure the
workpiece to a stable platform. It 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 only, 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.

INSTRUCTIONS FOR ALL
SAWS
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 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 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 minimise 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 sawing into
existing walls or other blind areas. The
protruding blade may cut objects that can cause
kickback.
