• Never hold the workpiece in your hands or across
your leg while cutting. Secure the workpiece to a
stable platform. It is important to support the work
properly to minimise 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 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 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.

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 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. Posi-
tion 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 con-
trolled 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. In-
vestigate 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 adjust-
ment 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.
• The lower guard may be retracted manually only for
special cuts such as "plunge cuts" and "compound
cuts". Raise the lower guard by the retracting han-
dle and as soon as the blade enters the material, the
lower guard must be released. For all other sawing,
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-
WARNING
plications that produce a consider-
able amount of dust, use an OSHA compliant dust
extraction solution in accordance with the solu-
tion's operating instructions.
• Always use common sense and be cautious when
using tools. It is not possible to anticipate every
situation that could result in a dangerous outcome.
Do not use this tool if you do not understand these
operating instructions or you feel the work is beyond
your capability; contact Milwaukee Tool or a trained
professional for additional information or training.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.
• Some dust created by power sanding,
WARNING
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 specially designed to
filter out microscopic particles.
