WARNING
Only use accessories with
maximum speed rating at least as high as
nameplate RPM of tool.
Selecting Blade
Always use sharp blades. Dull blades tend to
overload the tool and increase the chance of kick-
back (see "Preventing Kickback"). A combination
blade is included with your tool for general use in
wood. Select the right blade for your job. Read the
manufacturer's instructions before use.

Rip & Crosscut
A multi-purpose blade for ripping, cross cut-
ting and mitering in hardwoods, softwoods,
plywood and composition materials.
Framing-Rip
Designed for fast and accurate ripping along
the grain in hard-or softwoods where a
smooth cross cut is not necessary.
Plywood-Veneer
Recommended for cutting plywood, com-
position materials and all types of wood
where a slightly smoother fi nish is needed.
Finish & Trim
Especially designed for cross cutting and
mitering in materials where a very smooth
cut is necessary. Also cuts aluminum.
Installing and Removing Blades
1. Unplug tool before installing or removing blades.
2. Place the saw on a fl at surface with the blade fac-
ing upwards. To remove the bolt from the spindle,
push in the spindle lock button. While holding in
the spindle lock button, use the wrench provided
with the tool to turn the bolt counterclockwise.
Remove the bolt and outer blade fl ange.
3. Slide the lower guard lever up to raise the
lower guard. Remove the blade from the spin-
dle. Always clean the spindle, upper guard and
lower guard to remove any dirt and sawdust.
NOTE: Do not remove inner blade fl ange. Larger di-
ameter of inner fl ange (Fig. 3) should face the blade.

5. Place the outer blade fl ange on the spindle and
hand tighten the bolt. Larger diameter of outer
fl ange (Fig. 3) should rest on blade.
6. While holding the spindle lock button in, use the
wrench to turn the bolt clockwise and tighten.
Adjusting Depth
1. Unplug tool.
2. To adjust the depth of the cut, hold the saw by the
Tilt-Lok™ handle and loosen the depth adjusting
lever by lifting it up and away from the shoe (Fig. 5).
Fig. 5
3. Raise or lower the shoe to the desired position.
Markings in 1/4" increments are located on the
inner side of the upper guard for depth setting.
For the proper depth setting, the blade should
extend no more than 1/4" below the material
being cut (Fig. 6).
4. Move the depth adjusting lever towards the shoe
and push down to secure the position.
Bolt
Adjusting Bevel Angle
1. Unplug tool.
2. To adjust the angle of the cut, hold the saw by the

4. Move the bevel adjusting lever away from the
blade and push down to secure the position.
Adjusting Tilt-Lok™ Handle Angle
This circular saw is equipped with an adjustable han-
dle. The Tilt-Lok™ feature allows the user to adjust
the angle of the handle for optimum cutting positions.
1. Unplug tool.
2. Press in and hold the handle lever release button.
3. Loosen the handle release lever by lifting it up
and away from the Tilt-Lok™ handle.
4. To adjust the handle position, hold the front han-
dle and rotate the Tilt-Lok™ handle to the desired
angle as indicated by the handle rotation adjust-
ment markings (Fig. 9). The Tilt-Lok™ feature has
eight (8) detents which allow the handle to snap
into position. Allow the detent to snap into place.
Fig. 9
NOTE: The blade depth setting will determine the
range of Tilt-Lok™ positions available for the ap-
plication. See "Adjusting Depth" for instructions
on adjusting the blade depth.
5. Push the handle release lever back into the
handle until it snaps into place.
WARNING
Do not operate saw with
handle lever release button pressed in or with
handle not locked into position.
NOTE: The saw will not operate if the handle
release lever is not properly secured.
WARNING
If the Tilt-Lok™ handle
moves with the handle release lever in the
locked position, do not operate saw. Return
the circular saw to a MILWAUKEE service facil-
ity for repair immediately.
Adjusting the Blade to Shoe
The shoe has been adjusted at the factory to a 90
degree setting. Inspect the saw regularly to make
sure the blade is 90 degrees to the shoe.

Bevel adjustment screw
1. Unplug tool.
2. Set the bevel pointer to zero.
3. To make sure the blade is 90 degrees to the shoe,
place saw on the blade side and retract lower
guard. Place a square against the blade and shoe
to inspect the degree setting (Fig. 10).
4. To adjust the degree setting, loosen the bevel
adjusting lever up by lifting it up towards the blade.
Turn the bevel adjustment screw in or out until the
blade is at a 90 degree angle with the shoe.
5. Check that the bevel pointer is at 0 degrees. To
adjust the bevel pointer, loosen the two screws in
the front handle and reposition the bevel pointer
to 0 degrees.
OPERATION
WARNING
To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side shields.
Causes and Operator Prevention of Kickback:
KICKBACK is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an un-
controlled 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 reac-
tion 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.
