• 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
CIRCULAR SAW
Cutting procedures
•
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.
• 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 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.
• 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 eccentrically, 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, bound 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 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 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 and check 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 lower guard for proper closing before each
use. Do not operate the saw if 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, 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.
• Lower guard should be retracted manually only
for special cuts such as “plunge cuts” and “com-
pound cuts.”
Raise lower guard by retracting handle
and as soon as blade enters the material, the lower
guard must be released. For all other sawing, the
lower guard should operate automatically.
• Alw
ays 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.
•
Maintain labels and nameplates.
These carry
important information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.

WARNING
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paint
