WARNING
Always remove battery
pack before changing or removing acces-
sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
Causes and Operator Prevention of KICK-
BACK:
KICKBACK is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the work-
piece 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 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 caus-
ing 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 precau-
tions 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 KICKBACK forces. KICKBACK
forces can be controlled by the operator, if
proper precautions are taken.
2. 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.
3. When restarting a saw in the workpiece,
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.
OPERATION
4. Support large panels to minimize 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.
5. Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow
kerf causing excessive friction, blade binding
and KICKBACK.
6. Blade depth and bevel adjusting locking le-
vers 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 KICKBACK. 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.
General Operation
Always clamp the workpiece securely on a saw
horse or bench (Fig. 8). 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 (Fig. 9).

2. Line up the sight line with your cutting line. Posi-
tion 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 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.
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 cut-
ting 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 fi rm grip
and release the trigger immediately. Hold the
saw motionless in the workpiece until the blade
comes to a complete stop.
7. After fi nishing a cut, be sure the lower guard
closes and the blade comes to a complete stop
before setting the saw down.
Electric Brake
This tool features an electric brake. The brake
engages when the trigger is released, causing the
blade to stop and allowing you to proceed with your
work. Generally, the saw blade stops within two
seconds. 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
