CORDLESS 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 tool, they cannot be cut by
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 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.
5. Hold power
surfaces when performing an operation where
the cutting tool may contact hidden wiring.
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.

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 tool will run eccentrically, causing
loss of control.
8. Never
washers or bolt. The blade washers and bolt
were specially designed for your tool, for optimum
performance and safety of operation.
Kickback causes and related warnings
− Kickback is a sudden reaction to a pinched, bound
or misaligned blade, causing an uncontrolled tool
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
GEA010-1
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 tool misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below.
9. Maintain a firm grip with both hands on the
tool and position your arms to resist kickback
GEB058-2
forces. Position your body to either side of
the blade, but not in line with the blade.
Kickback could cause the tool to jump backwards,
but kickback forces can be controlled by the
operator, if proper precautions are taken.
10. When blade is binding, or when interrupting a
cut for any reason, release the trigger and
hold the tool motionless in the material until
the blade comes to a complete stop. Never
attempt to remove the tool from the work or
pull the tool backward while the blade is in
motion or KICKBACK may occur. Investigate
and take corrective actions to eliminate the cause
of blade binding.
11. When restarting a tool in the workpiece,
center the blade in the kerf and check that
blade teeth are not engaged into the material.
If blade is binding, it may walk up or kickback
from the workpiece as the tool is restarted.
12. Support large panels to minimise the risk of
blade pinching and kickback. Large panels
gripping
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.
13. Do
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
