Portable circular saw for metals CSM 4060
– 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.
– 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.
– When ripping always use a rip fence
or straight edge guide.
This improves the accuracy of cut and
reduces the chance of blade binding.
– 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.
– 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.
– Before using the power tool and
saw blade, check them for damage,
imbalances and vibrations.
Conduct a test run!
– Use only saw blades which have
a permitted speed at least as high as
the nominal speed of the power tool.
– Switch on the portable circular saw
before guiding it towards the workpiece.
– Do not load the power tool to such
an extent that it stops.
– When using the power tool, hazardous
substances may be released.
Take suitable precautions (e.g. wear
a dust-proof mask).
– Never saw materials which contain
asbestos.
– Never saw light-weight metals which
have a magnesium content greater than
80 %. Risk of fire!
– If power tools are used outdoors or are
exposed to extreme metal dust, connect
via a residual-current-operated circuit-
breaker (tripping current max. 30 mA).
– Mark the power tool with adhesive labels
only. Do not drill any holes into the
housing.
Causes and operator prevention
of kickback:
– 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
jumb back toward the operator.
Kickback is result of saw misuse and/or
incorrect operating procedures or conditions
and can be avoided by taking proper
precautions as given below.
– 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.
– 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.
