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 facility for repair immediately.
Adjusting the Blade to Shoe
The shoe has been adjusted at the factory
to a 90 degree setting. Inspect the saw regu-
larly to make sure the blade is 90 degrees
to the shoe.
1. Unplug tool.
2. Set the bevel pointer to zero (Fig. 11).
Fig. 11
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. 12).

Bevel adjustment screw
4. To adjust the degree setting, loosen the
bevel adjusting lever up by lifting it up
towards the blade. Turn the bevel adjust-
ment 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, wear
safety goggles or glasses with side
shields. Unplug the tool before
changing accessories or making
adjustments.
Causes and Operator Prevention of
KICKBACK:
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, or cutting slot, closing
down, the blade stalls and the motor reac-
tion drives the unit rapidly back toward
the operator.
If the blade becomes twisted or mis-
aligned 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 operator.
KICKBACK is the result of tool misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below:
1. Maintain a fi rm grip with both hands
on the saw and position your body
and arm to allow you to resist KICK-
BACK forces. KICKBACK forces can
be controlled by the operator, if proper
precautions are taken.
2. When blade is binding, or when inter-
rupting a cut for any reason, release
the trigger and hold the saw motion-
less 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 cor-
rective actions to eliminate the cause
of blade binding.
3. When restarting a saw in the work-
piece, center the saw blade in the
kerf, or cut, 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.
4. Support large panels to minimize
the risk of blade pinching and KICK-
BACK. 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.
5. Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and KICKBACK.
6. Blade depth and bevel adjusting lock-
ing levers must be tight and secure
before making cut. If blade adjustment
shifts while cutting, it may cause binding
and KICKBACK.
7. Use extra caution when making a
"Pocket Cut" into existing walls
or other blind areas. The protruding
blade may cut objects that can cause
KICKBACK.
8. Set the depth of cut for no more than
1/8" to 1/4" greater than the thickness
of the stock. The less blade exposed,
the less chance of binding and KICK-
BACK. Before cutting, be sure depth
and bevel adjustments are tight.
9. Be cautious of pitchy, knotty, wet or
warped stock. These are most likely to
create pinching conditions and possible
KICKBACK. Do not rip warped lumber.
Avoid cutting nails.
10. Use a rip fence or edge guide when
ripping. Guides improve control and
reduce blade binding.
11. Stay alert. Any distraction can cause
twisting or binding. Repetitive cuts may
lull the user into careless movements.
