• 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.
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 flat 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.
6. If the saw binds and stalls, maintain a firm grip
and release the trigger immediately. Hold the saw
motionless in the workpiece until the blade comes
to a complete stop.
7. After finishing 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
delay 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 needs servicing by an authorized MILWAUKEE
service facility. 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.
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.
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.
To reduce the risk of electric shock,
WARNING
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.
