OPERATION
WARNING
Always remove battery pack
before changing or removing accessories.
Only use accessories specifi cally recommend-
ed for this tool. Others may be hazardous.
WARNING
To reduce the risk of injury,
keep hands away from the blade and other
moving parts. Always wear safety goggles or
glasses with side shields. Use only specifi -
cally recommended accessories. Others may
be hazardous.
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 incor-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given below:
• 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.
• 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 kick-
back 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 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.
General Operation
Always clamp the workpiece securely on a saw horse
or bench. See "APPLICATIONS" 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. 7).
Fig. 7
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 beginning cut.
4. While cutting, keep the shoe fl at against the work-
piece and maintain a fi rm 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.
6. If the saw binds and stalls, maintain a fi rm grip
and release the trigger immediately. 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.
8. When cutting plastic, avoid overheating the blade
and blade teeth to prevent melting the workpiece.
Electric Brake
The electric brake engages when the trigger is re-
leased, causing the blade to stop and allowing you
to proceed with your work. Generally, the saw blade
stops within two seconds. However, there may be a de-
lay between the time you release the trigger and when
the brake engages. Occasionally the brake may miss
completely. If the brake misses frequently, the saw
6
needs servicing by an authorized MILWAUKEE ser-
vice facility. The brake is not a substitute for the guard,
and you must always wait for the blade to stop com-
pletely before removing the saw from the workpiece.
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, dulling 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
• Battery charge is low

APPLICATIONS

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.
Fig. 8
Cross-Cutting Wood
Cross-cutting is cutting across the grain. Select the
proper blade for your job. Advance the saw slowly to
avoid splintering the wood.
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.
WARNING
To reduce the risk of elec-
tric shock, check work area for hidden pipes
and wires before making plunge cuts.
Plunge Cutting
Plunge cuts are made in the middle of the workpiece
when it can not be cut from an edge. We recommend
using a Sawzall ® reciprocating saw or jig saw for this
type of cut. However, if you must use a circular saw
to make a plunge cut, USE EXTREME CAUTION.
To maintain control of the saw during plunge cutting,
keep both hands on the saw.
1. Beginning at a corner, line up the sight line with
your cutting line. Tilt the saw forward, fi rmly fi xing
the front of the shoe on the workpiece (Fig. 9).
The blade should be just above cutting line, but
not touching it. Raise the lower guard using the
lower guard lever.
Fig. 9
2. To start the saw, push the lock-off button down
while pulling the trigger. Allow the motor to reach
full speed before beginning cut. Using the front
of the shoe as a hinge point, gradually lower the
back end of the saw into the workpiece. Release
the lower guard lever and grasp the front handle.
3. When the shoe rests flat against workpiece,
advance the saw to the far corner (Fig. 10). Re-
lease the trigger and allow the blade to come to a
complete stop before removing it from workpiece.
Repeat the above steps for each side of the open-
®
ing. Use a Sawzall reciprocating saw, jig saw or
small hand saw to fi nish the corners if they are not
completely cut through.
