BLADE PARALLEL TO THE MITER GAUGE GROOVE
(FIG. V)
To prevent personal injury, always disconnect plug from
the power source when making any adjustments.
This adjustment was made at the factory, but it should
be rechecked and adjusted if necessary.
This adjustment must be correct or kickback could result
and accurate cuts cannot be made.
1. Remove the yellow switch key and unplug
the saw.
2. Move the blade guard out of the way.
3. Raise the blade to the highest position and set at
the 0 ° angle (90 ° straight up).
4. Select and mark, with a felt tip marker, a blade
tooth having a "right set".
5. Place the combination square base (1) into the
right side miter gauge groove (2). (FIG. V)
6. Adjust the rule so it touches the front marked tooth
and lock ruler so it holds its position in the square
assembly.
7. Rotate the blade bringing the marked tooth to the
rear and about 1/2 inch above the table.
8. Carefully slide the combination square to the rear
until the ruler touches the marked tooth.
9. If the ruler touches the marked tooth at the front and
rear positions, no adjustment is needed at this time.

ADJUSTING THE BLADE TO BE PARALLEL TO
THE MITER GAUGE GROOVE (FIG. W)
1. If the front and rear measurements are not the
same, remove the combination square and loosen
the four adjusting screws (1) on the top of the table
about a half turn.
2. With a folded piece of cardboard covering the blade
to protect your hands, move the blade carefully to
the left or right as much as needed to align
the blade correctly.
3. Tighten the four screws (1) and remeasure, as
described in steps 4 to 9 in the prior section.
4. If sufficient adjustment cannot be made by the
adjusting screws (1), then also loosen the two
adjustment screws (2). Loosen these screws (2)
only if necessary.
5. Recheck blade clearance making sure that the
blade does not hit the table insert or other parts
when at the 90° and 45° settings.
6. Tighten all screws.

BASIC SAW OPERATIONS
RAISING THE BLADE (FIG. X)
To raise or lower the blade, turn the blade elevation
handwheel (1) to the desired blade height, and
then tighten lock handle (2) to maintain the desired
blade angle.
Fig. X
TILTING THE BLADE
Two methods are available for tilting the saw blade.
Rapid blade tilting
Loosen blade lock handle (2), move the hand wheel (1)
to the desired angle and tighten lock handle.
Fine adjustment blade tilting
Loosen blade lock handle (2), push in hand wheel (1)
and at the same time turn the hand wheel (1) to tilt the
saw blade. When the saw blade is at the desired angle,
tighten lock handle (2).
ON / OFF SWITCH (FIG. Y)
The ON / OFF switch has a removable key. With the key
removed from the switch, unauthorized and hazardous
use by children and others is minimized.
1. To turn the saw ON, insert key (1) into the slot in the
switch (2). Move the switch upward to the ON position.
2. To turn the saw OFF, move the switch downward.
3. To lock the switch in the OFF position, grasp the end
(or yellow part) of the switch toggle (1), and pull it out.
4. With the switch key removed_the switch will not operate.
5. If the switch key is removed while the saw is running,
it can be turned OFF but cannot be restarted without
inserting the switch key (1).

OVERLOAD PROTECTION (FIG. Y)
This saw has a reset overload relay button (3) that will
restart the motor after it shuts off due to overloading or
low voltage. If the motor stops during operation, turn the
ON/OFF switch to tile OFF position. Wait about five
minutes for the motor to cool. Push in on the reset button
(3) and turn the switch to the ON position.
The ON / OFF switch should be in the OFF position, and
the plug removed from the power source while the cool
down takes place to prevent accidental starting when the
reset button is pushed. Overheating may be caused by
misaligned parts or dull blade. Inspect your saw for
proper setup before using it again.
CUTTING OPERATIONS
There are two basic types of cuts: ripping and
crosscutting. Ripping is cutting along the length and
the grain of the workpiece. Crosscutting is cutting
either across the width or across the grain of the
workpiece. Neither ripping nor crosscutting may be
done safely freehand. Ripping requires the use of the
rip fence, and crosscutting requires the miter gauge.
CAUTION: Before using the saw each and every time,
check the following:
1. Blade is tight on the arbor.
2. Bevel angle lock knob is tight.
3. If ripping, fence knob is tight and fence is parallel
to the miter gauge grooves.
4. Blade guard is in place and working properly.
5. Safety glasses are being worn.
The failure to adhere to these common safety rules, and
those printed in the front of this manual, can greatly
increase the likelihood of injury.
