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,
cutting material that is too thick, cutting materials
too quickly, or cutting hard metals such as stain-
less steel. To prevent the overload 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 and unplug the tool.
2. Remove the blade from the workpiece.
This tool is intended for cutting unhardened fer-
rous metal and non-ferrous metal. Refer to the
"Accessories" 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 blade, workpiece, chips, or chip
container with bare hands immediately after cut-
ting; they may be hot and could burn skin.
Cutting Materials Thicker than 1/4"
(3/4" Maximum Thickness)

age to the tool or blade, do not exceed the
Feed Rate and Maximum Cut Time for materi-
als thicker than 1/4", as charted below.
Between Maximum Cut Times, allow the tool
to cool down for 6 minutes of running with no
load or 60 minutes switched off.
Cutting too fast or too long in heavy material
will damage the tool if the tool is not allowed
to cool.
Cutting too slow will cause excessive wear
on the blade.
When cutting materials over 1/4", certain guide-
lines must be followed to avoid serious damage to
the tool and/or blade. The correct combination of
the following factors will allow for a sucessful cut
through thicker materials:
1. Material Thickness (do not cut materials thicker
than 3/4")
NOTE: If the material thickness is not shown
in the chart below, round up to the nearest
thickness listed in the chart and follow those
guidelines.
2. Maximum Length of Cut (the length of material
in inches through which the saw moves between
cool down periods)
3. Feed Rate (the speed at which the saw moves
through the material in seconds per inch)
4. Maximum Cutting Time (the total amount of
time that the saw can be under load between
cool down periods.
To reduce the risk of dam-
3. Allow the tool to rest for a miniumum of two
minutes.
4. 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.
5. Allow the tool to run under no load to ensure the
tool has properly cooled.
6. 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.

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 1"
lumber to workpiece and use the inside edge of
the shoe as a guide.
Pocket Cutting
Warning
shock, check work area for hidden pipes and
wires before making pocket cuts.
Pocket cuts are made in the middle of the workpiece
when it can not be cut from an edge. We recom-
mend using a Sawzall
saw for this type of cut. However, if you must use a
circular saw to make a pocket cut, USE EXTREME
CAUTION. To maintain control of the saw during
pocket cutting, keep both hands on the saw.
