Plunge Cutting
Plunge cuts are made in the middle of the workpiece
when it can not be cut from an edge. We recom-
mend 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, firmly fixing
the front of the shoe on the workpiece (Fig. 8).
The blade should be just above cutting line, but
not touching it. Raise the lower guard using the
lower guard lever.

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. 9). Re-
lease the trigger and allow the blade to come to
a complete stop before removing it from work-
piece. Repeat the above steps for each side of
the opening. Use a Sawzall ® reciprocating saw,
jig saw or small hand saw to finish the corners
if they are not completely cut through.
Overloading
Continuous overloading may cause permanent
damage to tool or battery pack.
When cutting masonry, use a diamond blade. Make
successive passes at depths of less than 1/4" to
achieve the desired depth. Cutting at a depth of
more than 1/4" will damage wheel. Unplug the tool
and frequently clean dust from air vents and guards.
When cutting metal, use a metal cutting blade. Set
depth of cut to full depth. Protect everyone in the
area from sparks.
Warning
dust, chips, and grit can
cause guard to hang up at any time. if saw
is used to cut masonry or metal, reserve and
mark it for that purpose only and return it to
a MILWAUKEE service facility for cleaning
and testing before using it for wood cutting.
Warning
Only use accessories with
maximum speed rating at least as high as
nameplate rPM of tool.
Warning
do not use tool for cutting
metal near flammable material. Sparks may
cause fire.
Cutting Masonry and Metal
MILWAUKEE circular saws are not intended for
continuous use in cutting metal or masonry. When
cutting these materials, use the correct blade. MIL-
WAUKEE does not recommend using bonded abra-
sive wheels on circular saws for any application.
Warning
To reduce the risk of elec-
tric shock, check work area for hidden pipes
and wires before making plunge cuts.
