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 properly, they must be serviced
before use. Lower guard may operate
sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
c) The lower guard may be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts.”
Raise the lower guard
by retracting handle and as soon as the blade
enters the material, the lower guard must be
released. For all other sawing, the lower guard
should operate automatically.
d) Always observe that the lower guard is
covering the blade before placing the saw
down on bench or floor.
An unprotected,
coasting blade will cause the saw to walk
backwards, cutting whatever is in its path. Be
aware of the time it takes for the blade to stop
after switch is released.
ADDITIONAL SAFETY
RULES FOR YOUR CIRCULAR
SAW
1. Only use saw blades recommended in the
specification.
2. Do not use any abrasive wheels.
3. Use only blade diameter(s) in accordance with
the markings.
4. Identify the correct saw blade to be used for the
material to be cut.
5. Use only saw blades that are marked with a
speed equal or higher than the speed marked on
the tool.
SAFETY INSTRUCTIONS
FOR ABRASIVE CUTTING-
OFF OPERATIONS
Cut-off machine safety warnings
a) The guard provided with the tool must
be securely attached to the power tool
and positioned 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 broken wheel fragments and
accidental contact with wheel.
b) Use only bonded reinforced or diamond
cut-off wheels for your power tool. Just
because an accessory can be attached to your
power tool, it does not assure 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 grinding, 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 excessively
and may cause loss of control.
