3. Push lower guard lever up to raise lower guard.
Place blade on spindle with teeth pointing the
same direction as the arrow on lower guard.
Release lower guard lever.
4. Place outer blade flange and blade bolt on
spindle.
5. Push in spindle lock button while turning bolt
clockwise with 6 mm hex wrench until spindle
locks. Tighten bolt securely.
6. To remove blade, reverse the above steps. Always
clean dirt and sawdust from spindle, fl anges, up-
per guard and lower guard after use.
Adjusting Depth
1. Unplug tool.
2. To adjust depth of cut, place saw on edge of
workbench and pull up depth adjusting lever.
3. Keeping shoe fl at against workbench, raise or
lower saw to desired position. Lowering saw will
increase depth of cut. Raising saw will decrease
depth of cut. For proper depth setting, blade
should extend no more than 1/4" below material
being cut. Use the depth of cut scale for standard
depths.
4. Push down depth adjusting lever to lock. Check
to be sure depth adjusting lever is secure.
Adjusting Miter Angle
1. Unplug tool.
2. To adjust angle of cut, place saw on edge or
workbench and pull up miter adjusting lever.
3. Hold down shoe and slide saw to desired position
according to markings on miter scale. Positive
stops are located at 0°, 45°, and 56°.
4. To increase the angle of cut above 45° up to 56˚,
push in the 56° override button and tip the saw
to the desired angle.
5. Push down miter lever to lock. Check angle with
a square. Also check to be sure miter adjusting
lever is secure before cutting.
Repositioning Adjustment Levers
The Miter Adjusting Lever and and the Depth
Adjusting Lever can be repositioned to the best
tightening position.
1. Pull out the lever and rotate to the desired posi-
tion.
2. Push in the lever, and press down to lock.
3. Check that the adjustment is secure.
Adjusting the Blade to Shoe
The shoe has been adjusted at the factory to a 90
degree setting. Inspect the saw regularly to make
sure the blade is 90 degrees to the shoe.
1. Unplug tool.
2. Set the bevel pointer to zero.
3. To make sure the blade is 90 degrees to the shoe,
place saw on the blade side and retract lower
guard. Place a square against the blade and shoe
to inspect the degree setting (Fig. 3).
4. To adjust the degree setting, loosen the miter
adjusting lever. Turn the bevel adjustment screw
in or out until the blade is at a 90 degree angle
with the shoe.
5. Tighten the miter adjusting lever securely.

OPERATION
WARNING
To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side shields.
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 (Fig. 4).

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 (Fig. 5).

3. Set the depth of cut for no more than 1/8" to 1/4"
greater than the thickness of the stock (Fig. 6).
The less blade exposed, the less chance of bind-
ing 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
paneling, formica, etc. must be well supported
over their entire length (Fig. 7) (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
moving. 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.

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
⅛"-¼"
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 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 fl at against workpiece
and maintain a fi rm 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 fi rm grip and release
trigger immediately. Correct problem before
continuing (see "Preventing Kickback").
6. After fi nishing a cut, be sure lower guard closes
and blade comes to a complete stop before set-
ting down saw.
