DANGER:
1. 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.
2. Do not reach underneath the work-
piece. The guard cannot protect you
from the blade below the workpiece.
3. Adjust the cutting depth to the thick-
ness 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 tools by insulated gripping sur-
faces when performing an operation
where the cutting tool may contact
hidden wiring or its own cord. Contact
with a "live" wire will make exposed
metal parts of the tool "live" and shock
the operator.
6. When ripping always use a rip fence
or straight edge guide. This improves
the accuracy of cut and reduces the
chance for blade binding.
7. Always use blades with correct size
and shape (diamond versus round)
arbor holes. Blades that do not match
the mounting hardware of the saw will
run eccentrically, causing loss of con-
trol.
8. Never use damaged or incorrect blade
washers or bolts. The blade washers
and bolts were specially designed for
your saw, for optimum performance and
safety of operation.
9. Causes and Operator Prevention of
kickback:
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 operator.
Kickback is the result of saw misuse and/or
incorrect operating procedures or conditions
and can be avoided by taking proper precau-
tions as given below:
a. Maintain a fi rm 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.
b. When blade is binding, or when inter-
rupting a cut for any reason, release
the trigger and hold the saw motion-
less 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 cor-
rective actions to eliminate the cause
of blade binding.
c. When restarting a saw in the work-
piece, center the saw blade in the kerf
and check that saw teeth are not en-
gaged into the material. If saw blade is
binding, it may walk up or kickback from
the workpiece as the saw is restarted.
d. Support large panels to minimize 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.
e. Do not use dull or damaged blade.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
f. Blade depth and bevel adjusting lock-
ing levers must be tight and secure
before making cut. If blade adjustment
shifts while cutting, it may cause binding
and kickback.
g. 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.
10. 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 po-
sition. 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.
11. Check the operation and condition
of the lower guard spring. If the
guard and the spring are not operat-
ing properly, they must be serviced
before use. Lower guard may operate
sluggishly due to damaged parts, gum-
my deposits, or a buildup of debris.
12. Lower guard should be retracted
manually only for special cuts such
as "Plunge Cuts" and "Compound
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.
13. Always observe that the lower guard
is covering the blade before placing
saw down on bench or fl oor. An un-
protected, 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.
14. Maintain labels and nameplates. These
carry important information. If unread-
able or missing, contact a MILWAUKEE
service facility for a free replacement.
15. WARNING: Some dust created by
power sanding, sawing, grinding, drill-
ing, and other construction activities
contains chemicals known to cause
cancer, birth defects or other reproduc-
tive 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 ven-
tilated area, and work with approved
safety equipment, such as those dust
masks that are specifi cally designed to
fi lter out microscopic particles.
