NOTE: The blade depth setting will determine
the range of Tilt-Lok™ positions available for the
application. 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.
Do not operate saw with handle
WARNING
lever release button pressed in or
with handle not locked into position.
If the Tilt-Lok™ handle moves with the handle
release lever in the locked position, do not oper-
ate saw. Return the circular saw to a MILWAUKEE
service facility for repair immediately.
Adjusting the Blade to Shoe
The shoe has been adjusted at the factory to a 90º
setting. Inspect the saw regularly to make sure the
blade is 90º to the shoe.
1. Unplug tool.
2. Set the bevel pointer to zero.
3. To make sure the blade is 90º to the shoe,
place saw on the blade side and retract low-
er guard. Place a square against the blade
and shoe to inspect the degree setting.
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 90º angle with the shoe.
5. Check that the bevel pointer is at 0º. To adjust the
bevel pointer, loosen the two screws in the front
handle and reposition the bevel pointer to 0º.

OPERATION
To reduce the risk of injury, always
WARNING
wear proper eye protection marked
to comply with ANSI Z87.1.
When working in dusty situations, wear appro-
priate respiratory protection or use an OSHA
compliant dust extraction solution.
Always unplug tool before attaching or removing
accessories or making adjustments. Use only
specifically 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 firm 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.
