6. If the saw binds and stalls, maintain a firm grip
and release the trigger immediately. Hold the
saw motionless in the workpiece until the blade
comes to a complete stop.
7. After finishing a cut, be sure the lower guard
closes and the blade comes to a complete stop
before setting the saw down.
Overload Protector
The overload protector automatically turns off the
tool when the motor is overloaded. The tool can
become overloaded when using a dull blade or
cutting materials too quickly. To prevent the over-
load protector from activating, always use a sharp
blade and follow the cutting instructions under the
"Applications" section. Do not attempt to defeat or
override the overload protector.
If the tool turns off automatically:
1. Release the trigger.
2. Remove the blade from the workpiece.
3. Reset the overload protector by pushing in the
button.
Note: If the tool does not start after pushing the
button, allow the tool to cool for a few minutes
and try again.
4. Allow the tool to run under no load to ensure the
tool has properly cooled.
5. Resume the cut. 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.
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
• Blade is loose.
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
• Battery charge is low
Electric Brake
The electric 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. However, there
may be a delay between the time you release the
trigger and when the brake engages. Occasionally
the brake may miss completely. If the brake misses
frequently, the saw needs servicing by an autho-
rized 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.
applicaTions
This tool is intended for cutting unhardened ferrous
metal and non-ferrous metal. Refer to the "Acces-
sories" section for a list of blades to be used for
the proper applications of this tool. The following
precautions must be followed to reduce the risk
of injury:
• Do not cut stacked materials. Cut one piece at a
time.
• Do not cut hardened steel.
• Cut materials with the wider edge of the shoe over
the clamped side of the material.
• Do not touch the saw blade, workpiece, or cutting
chips with bare hands immediately after cutting;
they may be hot and could burn skin.
• Adjust the cutting angle of the blade to the work-
piece, so the blade goes through the thinnest
sections.
Cutting Angled Materials
When cutting angle materials, tilt the tool back to
avoid having the lower guard rest on the angle.
Correct Technique
Cutting Thin or Corrugated Materials
Cut thin and corrugated materials at least 1" from
the edge of the workpiece to avoid injury or dam-
age to the tool caused by thin strips of metal being
pulled into the upper guard.
Cutting Large Sheets
Large sheets sag or bend if they are not correctly
supported. If you attempt to cut without leveling
and properly supporting the workpiece, the blade
will tend to bind, causing KICKBACK.
Support large sheets. Be sure to set the depth of
the cut so that you only cut through the workpiece,
not through the supports.
When cutting widths greater than 4", clamp or tack
1" lumber to workpiece and use the inside edge of
the shoe as a guide.
