eyes, additionally seek medical help. Liquid ejected
from the battery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behavior resulting in fire, explosion or
risk of injury.
• Do not expose a battery pack or tool to fire or exces-
sive temperature. Exposure to fire or temperature
above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions. Charging im-
properly or at temperatures outside the specified range
may damage the battery and increase the risk of fire.
SERVICE
• Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
METAL SAW
Cutting procedures
• Keep hands away from cutting area
DANGER
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.
• Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the workpiece.
• 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.
• Never hold workpiece being cut in your hands or
across your leg while cutting. Secure the work-
piece to a stable platform. It is important to support
the work properly to minimize body exposure, blade
binding, or loss of control.
• 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.
• 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 off-centre, 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.
Further safety instructions for all saws
Kickback causes and related warnings
-Kickback is a sudden reaction to a pinched, jammed
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 jammed tightly by the
kerf closing down, the blade stalls and the motor reac-
tion 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 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:
• 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.
• When restarting a saw in the workpiece, centre
the saw blade in the kerf so that saw teeth are not
engaged into the material. If saw blade is binding,
it may walk up or kickback from the workpiece as the
saw 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 set blades 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.
• Use extra caution when sawing into existing walls
or other blind areas. The protruding blade may cut
objects that can cause kickback.
Lower guard function
• Check the lower guard for proper closing before
each use. Do not operate the saw if the lower
guard does not move freely and close instantly.
Never clamp or tie the lower guard into the open
position. If saw is accidentally dropped, the lower
guard may be bent. Raise the lower guard with the
retracting handle and make sure it moves freely and
does not touch the blade or any other part, in all angles
and depths of cut.
• Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use. Lower
guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
• The lower guard should be retracted manually
only for special cuts such as "plunge cuts" and
"compound cuts." Raise the lower guard by retract-
ing handle and as soon as blade enters the material,
the lower guard must be released. For all other saw-
ing, the lower guard should operate automatically.
• Always observe that the lower guard is covering
the blade before placing saw down on bench or
floor. An unprotected, coasting blade will cause the
saw to walk backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade to stop after
switch is released.
• To reduce the risk of injury in ap-

plications that produce a consider-
able amount of dust, use an OSHA compliant dust
extraction solution in accordance with the solu-
