• Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow
kerf causing 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.
General Operation
Always clamp workpiece securely on a saw horse
or bench. See "Applications" for the correct way to
support your work in different situations. A typical
application is shown below.
1. Draw cutting line. Place front of shoe on edge of
workpiece without making blade contact. Hold
switch handle with one hand and top handle with
the other.

2. Line up sighting notch with your cutting line.
Position arms and body to resist kickback. Pull
trigger, allowing motor to reach full speed before
beginning cut.
3. While cutting, keep shoe flat against workpiece
and maintain a firm grip. Do not force saw
through the work. Forcing a saw can cause
kickback.
4. If making a partial cut, restarting in mid-cut or
correcting direction, allow blade to come to a
complete stop. To resume cutting, center blade
in kerf, back saw away from cutting edge a few
inches, pull trigger and re-enter cut slowly.
5. If saw stalls, maintain a firm grip and release
trigger immediately. Correct problem before
continuing (see "Preventing Kickback").
6. After finishing a cut, be sure lower guard closes
and blade comes to a complete stop before set-
ting down saw.
Troubleshooting
If blade does not want to follow straight line:
• Teeth are dull on one side. This is caused by
hitting a hard object such as a nail or stone,
dulling teeth on one side. The blade wants to
cut to the side with the sharpest teeth.
• Shoe is out of line or bent
• Blade is bent
• Failure to use rip fence or guide
If 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
• Failure to use correct blade
Grip saw with both hands, keeping
hands away from blade
Tighten depth and miter adjusting
levers securely
Set depth of cut 1/8"-1/4" greater
than thickness of stock
Rest saw on larger part of
workpiece, allowing smaller
part to fall away
Secure workpiece to
sturdy supports
