Intended use
The tool is intended for cutting in mild steel.
Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and can
only be operated on single-phase AC supply. They are
double-insulated and can, therefore, also be used from
sockets without earth wire.

General power tool safety warnings

WARNING: Read all safety warnings, instruc-
tions, illustrations and specifications provided with
this power tool. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious
injury.
Save all warnings and instructions for future
reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
METAL CUTTER SAFETY WARNINGS
Cutting procedures
1. 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.

2. Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
3. 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.
4. Never hold the workpiece in your hands or
across your leg while cutting. Secure the work-
piece to a stable platform. It is important to sup-
port the work properly to minimise body exposure,
blade binding, or loss of control.
5. Hold the power tool by insulated gripping sur-
faces, 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.
6. When ripping, always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
ENE022-1
7. 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.
ENF002-2
8. 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.
Kickback causes and related warnings
– kickback is a sudden reaction to a pinched,
jammed or misaligned saw blade, causing an
GEA010-2
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 workpiece 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.
GEB155-1
1. 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.
