3. When restarting a saw in the work-
piece, center the saw blade in the
kerf, or cut, 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.
4. Support large panels to minimize
the risk of blade pinching and KICK-
BACK. 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.
5. Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and KICKBACK.
6. 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.
7. Use extra caution when making a
“Pocket Cut” into existing walls
or other blind areas. The protruding
blade may cut objects that can cause
KICKBACK.
8. Set the depth of cut for no more than
1/8" to 1/4" greater than the thickness
of the stock. The less blade exposed,
the less chance of binding and KICK-
BACK. Before cutting, be sure depth
and bevel adjustments are tight.
9. Be cautious of pitchy, knotty, wet or
warped stock. These are most likely to
create pinching conditions and possible
KICKBACK. Do not rip warped lumber.
Avoid cutting nails.
10. Use a rip fence or edge guide when
ripping. Guides improve control and
reduce blade binding.
11. Stay alert. Any distraction can cause
twisting or binding. Repetitive cuts may
lull the user into careless movements.
General Operation
Always clamp the workpiece securely on a
saw horse or bench (Fig. 11). See “APPLICA-
TIONS” for the correct way to support your
work in different situations.
1. Draw a cutting line. Place the front of
the shoe on the edge of the workpiece
without making blade contact. Hold
the handle with one hand and the front
handle with the other (Fig. 12).
2. Line up the sight line with your cutting
line. Position your arms and body to
resist KICKBACK.
3. To start the saw, push the lock-off button
down while pulling the trigger. Allow the
motor to reach full speed before begin-
ning cut.
4. While cutting, keep the shoe fl at against
the workpiece and maintain a firm
grip. Do not force the saw through the
workpiece. Forcing a saw can cause
KICKBACK.
5. If making a partial cut, restarting in
mid-cut or correcting direction, allow
the blade to come to a complete stop.
To resume cutting, center the blade in
the kerf, back the saw away from cutting
edge a few inches, push the lock-off
button down while pulling the trigger and
re-enter the cut slowly.

APPLICATIONS
Troubleshooting
If the blade does not follow a straight line:
•
Teeth are dull. This is caused by hitting a
hard object such as a nail or stone, dull-
ing teeth on one side. The blade tends to
cut to the side with the sharpest teeth.
• Shoe is out of line or bent
• Blade is bent
• Rip fence or guide is not being used
If the blade binds, smokes or turns blue
from friction:
•
Blade is dull
• Blade is on backwards
• Blade is bent
• Blade is dirty
• Workpiece is not properly supported
• Incorrect blade is being used
6. If the saw binds and stalls, maintain
a fi rm grip and release the trigger im-
mediately. Hold the saw motionless in
the workpiece until the blade comes to
a complete stop.
7. After fi nishing a cut, be sure the lower
guard closes and the blade comes to a
complete stop before setting the saw
down.
Electric Brake
This tool features an electric brake. The
brake engages when the trigger is released,
causing the blade to stop and allowing you to
proceed with your work. Generally, the saw
blade stops within two seconds. If the brake
misses frequently, the saw needs servicing
by an authorized MILWAUKEE service facil-
ity. The brake is not a substitute for the guard,
and you must always wait for the blade to
stop completely before removing the saw
from the workpiece.
Ripping Wood
Ripping is cutting lengthwise with the grain.
Select the proper blade for your job. Use a
rip fence for rips 4" wide or less. To install the
rip fence, slide the bar through the rip fence
slot in either side of the shoe. The width of
the cut is the distance from the inside of the
blade to the inside edge of the rip fence.
Adjust the rip fence for the desired width, and
lock the setting by tightening the rip fence
adjusting knob.
When ripping widths greater than 4", clamp
or tack 1" lumber to workpiece and use the
inside edge of the shoe as a guide.
Cutting Large Panels
Large panels and long boards sag or bend
if they are not correctly supported. If you
attempt to cut without leveling and properly
supporting the workpiece, the blade will tend
to bind, causing KICKBACK.
Support large panels. Be sure to set the
depth of the cut so that you only cut through
the workpiece, not through the supports.
