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 the power tool by insulated gripping
surfaces only, 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 use damaged or incorrect blade
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 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
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 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 not use dull or damaged blades. Unsharpened or
improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
14. 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.
15. Use extra caution when making a "plunge cut" into
existing walls or other blind areas.
The protruding
blade may cut objects that can cause kickback. For
plunge cuts, retract lower guard using retracting handle.
Lower guard function
16. Check lower guard for proper closing before
each use. Do not operate the tool if lower
guard does not move freely and close
instantly. Never clamp or tie the lower guard
into the open position.
If tool is accidentally
dropped, lower guard may be bent. Raise the
lower guard with the retracting lever and make
