Cutting procedures
• DANGER: Keep hands away from cutting
area and 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 wir-
ing or its own cord. 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.
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 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 operator.
Kickback is the result of saw misuse and/or incor-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given below:
• M aintain 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 jumb backwards, but kick-
back forces can be controlled by the operator, if
proper precautions are taken.
• W hen 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 correc-
tive actions to eliminate the cause of blade binding.
•When restarting a saw in the workpiece, center
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 blade. Unsharpened
or improperly set blades produce narrow kerf caus-
ing 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 saw if lower guard
does not move freely and close instantly. Never
clamp or tie the lower guard into the open posi-
tion. If saw is accidentally dropped, lower guard
may be bent. Raise the lower guard with the lower
guard lever 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 dam-
aged parts, gummy deposits, or a buildup of debris.
•Lower guard should be retracted manually only
for special cuts such as "plunge cuts" and "com-
pound cuts". Raise lower guard by lower guard
lever 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 cov-
ering 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
•crystalline silica from bricks and cement and other
masonry products, and
•arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are spe-
cially designed to filter out microscopic particles.
