work to be 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
Cutting procedures
a)
DANGER: Keep hands away from cutting
area and the blade. 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 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, 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, 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 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 so that the saw teeth
are not engaged into the material.
If a saw blade
binds, 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 the 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.
SAFETY INSTRUCTIONS FOR
CIRCULAR SAW WITH INNER
PENDULUM GUARD
Lower guard function
a) Check the lower guard for proper closing before
each use. Do not operate the saw if the lower
guard does not move freely and close instantly.
Never clamp or tie the lower guard into the open
position. If the saw is accidentally dropped, the
lower guard may be bent.
Raise the lower guard
with the retracting handle and make sure it moves
freely and does not touch the blade or any other part, in
all angles and depths of cut.
b) Check the operation of the lower guard spring.
If the guard and the spring are not operating
