CORDLESS METAL CUTTER
SAFETY WARNINGS
DANGER:
1. 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 shock the
operator.
6. When ripping always use a rip fence or
straight edge guide. This improves the accuracy
of cut and reduces the chance for 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 use damaged
washers or bolts. The blade washers and bolt
were specially designed for your tool, for optimum

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 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.
Maintain a firm grip with both hands on the
tool 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 tool to
jump backwards, but kickback forces can be
controlled by the
precautions are taken.
When blade is
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.
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.
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.
Do not use dull or damaged blades.
Unsharpened or improperly
produce narrow kerf causing excessive friction,
blade binding and kickback.
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.
