Adjusting Tilt-Lok™ Handle Angle
This circular saw is equipped with an adjustable
handle. 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 (Fig. 9).
4. To adjust the handle position, hold the front
handle and rotate the Tilt-Lok™ handle to the
desired angle as indicated by the handle rotation
adjustment markings (Fig. 10). The Tilt-Lok™
feature has eight (8) detents which allow the
handle to snap into position. Allow the detent to
snap into place.

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.
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. 11).
WARNING Do not operate saw with
handle lever release button pressed in or with
handle not locked into position.
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
facility for repair immediately.
4. To adjust the degree setting, loosen the bevel ad-
justing 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.
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.
NOTE: The saw will not operate if the handle
release lever is not properly secured.
• 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 (Fig. 12). See “APPLICATIONS” for the cor-
rect 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 Tilt-Lok™ handle with one hand
and the front handle with the other (Fig. 13).
2. Line up the sight line with your cutting line. Posi-
tion your arms and body to resist KICKBACK.
Pull the trigger, allowing the motor to reach full
speed before beginning to cut.
3. While cutting, keep the shoe fl at against the
workpiece and maintain a fi rm grip. Do not force
the saw through the workpiece. Forcing a saw
can cause KICKBACK.
4. 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, pull the trigger and re-enter
the cut slowly.
5. 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.
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.

Kickback causes and related warnings
– 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 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 kick-
back 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 kickback 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. Unsharp-
ened or improperly set blades produce narrow
kerf causing 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.
