Never use carbide-tipped, woodcutting, or circular machine Saw Blades. They
can cause severe personal injury from reactive forces, blade contact, or thrown
objects.
Only cut asphalt, concrete, stone, brick, and plastics with this Cut Off Saw.
Inspect the Saw Blade frequently, and replace immediately if the Blade is
cracked, or warped. Cracked or warped Saw Blades may shatter or break and
cause serious personal injury.
Always install the Saw Blade so that the arrow on the Blade points in the direction of the rotation of the spindle.
Keep hands and fingers away from the cutting area and Saw Blade.
Never attempt to cut more than one workpiece at a time.
When cutting a large workpiece, make sure its entire length is properly supported. If necessary, use a roller stand (not included).
Allow the Saw Blade to spin up to full speed before feeding it into a workpiece.
When turning off the Cut Off Saw, allow the Saw Blade to spin down and stop on
its own. Do not press against the Saw Blade to stop it.

Do not force the Saw Blade into the workpiece when cutting. Apply moderate
pressure, allowing the Saw Blade to cut without being forced.
To avoid accidental injury, always wear heavy duty work gloves when changing the Saw Blade.
The Saw Blade will become hot while cutting. Allow the Saw Blade to completely
cool before handling.
Turn off the Cut Off Saw and allow the Saw Blade to completely stop if the
Saw Blade is to be backed out of an uncompleted cut.
Never attempt to remove material stuck in the Cut Off Saw while it is operating.
KICKBACK PRECAUTIONS
Make sure the workpiece is free from nails, metal rebar, and any other foreign
objects that could damage the Saw Blade or cause “kickback”.
Causes and operator prevention of “kickback”: Kickback is a sudden reaction
to a pinched, bound, or misaligned Saw Blade, causing an uncontrolled Cut Off
Saw to lift up and out from the workpiece toward the operator. When the Saw Blade
SKU 94488 For technical questions, please call 1-800-444-3353 PAGE 6
is pinched or bound tightly by the kerf closing down, the Saw Blade stalls and the
engine reaction drives the Cut Off Saw rapidly back toward the operator. If the Saw
Blade becomes twisted or misaligned in the cut, the teeth at the back edge of the
Saw Blade can raise the Cut Off Saw (walk up) toward the operator. Kickback is a
result of tool misuse and/or incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given below:
Maintain control of the Cut Off Saw at all times. Never allow the rotating Saw
•
Blade to rest on the workpiece without holding on to the Saw with both hands.
When the Saw Blade is binding, or when interrupting a cut for any reason,
•
turn off the Cut Off Saw and hold the Saw motionless until the Saw Blade
comes to a complete stop. Never attempt to remove the Saw Blade from the
workpiece or pull the Saw backward while the Saw Blade is in motion or kickback may occur. Investigate and take corrective actions to eliminate the cause
of Saw Blade binding.
When restarting the Cut Off Saw on a workpiece, center the Saw Blade
•
in the pre-cut kerf and check that the Saw Teeth are not engaged into the
workpiece. If the Saw Blade is binding, the Cut Off Saw may walk up or kick-
back as the Saw is restarted.
1.
Support large panels with roller stands (not included) to minimize the risk
•
of Saw Blade pinching and kickback. Large panels tend to sag under their
own weight. Supports must be placed under the panel and near the outer edge
of the panel.
Do not use a dull or damaged Saw Blade. Unsharpened or improperly set
•
Saw Blades produce a narrow kerf causing excessive friction, Saw Blade binding and kickback.
Push the Saw Blade past the workpiece prior to release.
•
Make sure to check the Blade Guard for proper operation. Never disable
•
the Guard. Do not use the Cut Off Saw if the Guard assembly does not operate properly. Before each use, make sure the Blade Guard does not touch the
Saw Blade.
MISC. PRECAUTIONS
WARNING! Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities, contain chemicals known (to the State of California) to
cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are: lead from lead-based paints, crystalline silica from bricks and cement or other masonry products, arsenic and chromium from chemically treated
lumber. Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well ventilated
