Preventing Kickback
Kickback is the sudden reaction to a pinched blade,
which could cause a saw that is not under control
to lift up and out of the workpiece towards the
user. Take the precautions below to help prevent
kickback.
1. Maintain a fi rm grip and correct body position.
Position arms and body to control the upward
and backward reaction force of kickback.
2. Keep blades sharp and clean. A sharp blade
will tend to cut its way out of a pinching condi-
tion. A dull blade produces a narrow kerf (path
cut by blade) and is likely to be pinched by the
workpiece. Dull or pitch coated blades also tend
to encourage the user to force the saw, causing
reduced control and blade binding. Any blade
with a small set, even though it is sharp, may
be likely to kick back.
3. 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 miter
adjustments are tight.
4. 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.
5. Support workpiece properly. Improperly sup-
ported material can sag or bow, pinching the
blade. When cutting down the center of your
workpiece, support material on both sides of the
cut. Large sheets of thin material such as panel-
ing, formica, etc. must be well supported over
their entire length (see "Cutting Large Panels").
When cutting the end off of your workpiece, rest
the saw on the supported portion outside of the
supports and allow the cut off end to fall away
(see "General Operation").
6. Always allow blade to come to a full stop before
removing the saw from the workpiece. Never
remove the saw from a cut while the blade is mov-
ing. If restarting or correcting direction in mid-cut,
allow blade to coast to a stop, back saw up a few
inches and center it in the kerf before restarting.
OPERATION
7. Stay alert. Any distraction can cause twisting or
binding. Repetitive cuts may lull the user into
careless movements.
8. Use care when making bevel cuts. Because of
the increased amount of blade engagement with
the work and decreased stability of the shoe when
making bevel cuts, kickback may occur if improp-
erly used. Keep shoe fi rmly against workpiece.
9. Do not force tool. Forcing a saw reduces control
and cutting effi ciency.
10.Use rip fence or edge guide when ripping. Guides
improve control and reduce blade binding (see
"Ripping Wood").
If kickback should occur, continue to grip the saw
fi rmly and immediately release trigger.
General Operation
Always clamp the workpiece securely on a saw
horse or bench (Fig. 12). See "APPLICATIONS"
for the correct way to support your work in differ-
ent situations.

1. Draw a cutting line. Place the front of the shoe on
the edge of the workpiece without making blade
contact. Hold the Tilt-Lok™ handle with one hand
and the front handle with the other (Fig. 13).

2. Line up the sight line with your cutting line. Posi-
tion your arms and body to resist KICKBACK.
Pull the trigger, allowing the motor to reach full
speed before beginning to cut.
3. 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.
4. 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 cutting
edge a few inches, pull the trigger and re-enter
the cut slowly.
5. 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.
6. After fi nishing a cut, be sure the lower guard
closes and the blade comes to a complete stop
before setting the saw down.

APPLICATIONS

WARNING
To reduce the risk of injury,
always unplug tool before attaching or
removing accessories or making adjust-
ments. Use only specifi cally recommended
accessories. Others may be hazardous.
WARNING

APPLICATION SUGGESTED TILT-LOK POSITIONS*
For cuts made at or near waist level Handle in lower positions (Fig. 15) allows for more leverage when
pushing the saw through the workpiece.
For shallow cuts made at or near Handle in lower positions allows the user to apply increased downward
waist level force during shallow cuts.
For cuts made below the waist, as Handle in higher positions (Fig. 16) reduce the amount of "bending
in fl ooring applications over" by the user. Higher handle positions allow the user to apply an
increased downward force on the saw.
For cuts made overhead, as in ceil- Handle in higher positions reduce the amount of extended reach by
ing applications the user for overhead cuts. Higher handle positions allow the user to
apply an increased upward force on the saw.
* These are only suggested positions; the actual optimum cutting position may vary depending on the actual applica-
tion and user preference.

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
Selecting Tilt-Lok™ Handle Positions
The Tilt-Lok™ handle is a feature which allows the
user to adjust the angle of the handle for optimum
cutting positions. The Tilt-Lok™ handle has eight (8)
detents which allow the handle to snap into position
(Fig.14). See "Adjusting Tilt-Lok™ Handle" for
instuctions on adjusting the handle. Refer to the
chart below for suggested handle positions.
