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 piece being cut in your hands
or across your leg. Secure the workpiece
to a stable platform. It is important to sup-
port the work properly to minimize body ex-
posure, blade binding, or loss of control.
e) Hold the power tool by insulated grip-
ping 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 mount-
ing hardware of the saw will run eccentri-
cally, 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 op-
eration.

KICKBACK CAUSES AND RELATED WARN-
INGS
– 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 rap-
idly 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 precau-
tions 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 inter-
rupting 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 work-
piece 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. Un-
sharpened 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.
SAFETY INSTRUCTIONS FOR PLUNGE-CUT
CIRCULAR SAW
GUARD FUNCTION
a) Check guard for proper closing before
each use. Do not operate the saw if
guard does not move freely and enclose
the blade instantly. Never clamp or tie
the guard so that the blade is exposed. If
saw is accidentally dropped, guard may be
bent. Check to make sure that guard moves
freely and does not touch the blade or any
other part, in all angles and depths of cut.
b) Check the operation and condition of the
guard return spring. If the guard and the
spring are not operating properly, they
must be serviced before use. Guard may
operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
c) Assure that the base plate of the saw will
not shift while performing the „plunge
cut" when the blade bevel setting is not
at 90°. Blade shifting sideways will cause
binding and likely kick back.
d) Always observe that the guard is cover-
ing the blade before placing saw down
on bench or floor. An unprotected, coast-
ing blade will cause the saw to walk back-
wards, cutting whatever is in its path. Be
aware of the time it takes for the blade to
stop after switch is released.
CUT-OFF MACHINE SAFETY WARNINGS
a) The guard provided with the tool must be
securely attached to the power tool and po-
sitioned for maximum safety, so the least
amount of wheel is exposed towards the
operator. Position yourself and bystanders
away from the plane of the rotating wheel.
The guard helps to protect operator from bro-
ken wheel fragments and accidental contact
with wheel.
b) Use only diamond cut-off wheels for your
power tool. Just because an accessory can
be attached to your power tool, it does not as-
sure safe operation.
c) The rated speed of the accessory must be at
least equal to the maximum speed marked
on the power tool. Accessories running faster
than their rated speed can break and fly apart.
d) Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grind-
ing, side forces applied to these wheels may
cause them to shatter.
e) Always use undamaged wheel flanges that
are of correct diameter for your selected
wheel. Proper wheel flanges support the
wheel thus reducing the possibility of wheel
breakage.
f) Do not use worn down reinforced wheels
from larger power tools. Wheels intended
for a larger power tool are not suitable for the
higher speed of a smaller tool and may burst.
g) The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannot be adequately guarded or
controlled.
h) The arbour size of wheels and flanges must
properly fit the spindle of the power tool.
Wheels and flanges with arbour holes that
do not match the mounting hardware of the
power tool will run out of balance, vibrate ex-
cessively and may cause loss of control.
i) Do not use damaged wheels. Before each
use, inspect the wheels for chips and
cracks. If power tool or wheel is dropped,
inspect for damage or install an undam-
