farther take time out to read the following important instructions, the
alignment of your new saw is most, important for making accurate cuts, the time spent here will add con¬
siderably TO YOUR OVERALL ENJOYMENT OF THIS FINE PRODUCT.
NOTE: SECURE TABLE FRAME OF UNIT TO A STURDY WORK BENCH, APPROPRIATE TABLE, OR LEG STAND, WITH SCREWS OR
BOLTS BEFORE MAKING ALIGNMENTS OR OPERATING.
ADJUSTING BASE TO ARM
Make certain the base is absolutely snug around the arm.
To do this refer to fig. A1 and adjust as follows:
1. Tighten the 5/16" bolt with a wrench until base is snug
around the arm and no appreciable play is noted.
2. Place the 3/8" I.D. Washer over the threaded end of the
base clamp (lubricate this washer and threads with a
small amount of grease). Install the base clamp in the
upper hole using the 3/8" square nut in the recess of
the base casting.
3. Position base clamp so that when it is locked the handle
position will be upright. If it is not, loosen the clamp rod
sufficiently to permit nut to come out of recess in
casting, then turn the nut 1/4 or 1/2 turn while holding
clamp rod. Retighten base clamp.
4. Place insert into plastic knob. Push knob on clamp
handle.
5. Release the base clamp by pulling it toward you, and
pull out the miter locator pin. You should now be able to
push the arm to the right and left and feel a slight drag.
6. If it is too hard to move, loosen the 5/16" bolt a little.
NOTE: The upper saw guard should be approx,
parallel with the table when the blade is touch¬
ing the table. If it is not, adjust the table by
turning the nuts on the table adjusting screws.
You will notice the mounting bolts, which hold the table to
the frame, are quite long. The large flange nuts, on the top
and bottom of the frame, suspend the table above the
frame about 1". There is an important reason for this con¬
struction. By turning these nuts up or down we can adjust
the table parallel to the arm. If the table is parallel to the
arm, then any groove you cut will be the same depth from
front to back. A simple method of adjusting the table to be
parallel with the arm is as follows:
1. With arm in cross cut position tighten base clamp
handle. Turn the anti-kickback rod on the guard upside-
down.
The
lower
end
of
the
rod
will
be
used as an indicator to determine if the entire table sur¬
face is the same distance from the arm.
2. Set the elevation adjustment so the end of the rod is
about 1/8" above the table top. Tighten elevating wing
nut. (Fig.A-2)
3. Push the saw all the way back. If the rod strikes the
surface, as you push it back, elevate it a little more so it
is 1/8" above as before.
4. Pull saw forward. Release base clamp handle, pull miter
locator pin and move the arm to your right until 30° is
indicated on the miter scale. As you move the arm, if the
end of the rod strikes the table, elevate it a little more
as before. With the arm 30° to the right, base clamp
handle tightened and the saw all the way back, turn the
height adjustment until the rod is just above the sur¬
face of the table and lock elevating wing nut.
5. Hand tighten the nuts on the back right table
suspension stud while still in 45° right position.
6. Pull the saw forward to the end of the track. If the end
of the rod strikes the table do not change the height ad¬
justment of the saw. Instead, lower the front right side
of the table by turning the upper nut on the suspension
stud up a few turns. You should now be able to push the
front right corner of the table down so the rod indicator
can pass over the surface without striking it.
7. Adjust the suspension stud nuts so the top of the table
on the front right side just touches the end of the anti-
kickback rod the same as the back. Tighten the nuts by
hand.
8. Release base clamp handle and swing the arm to the
left until 30° is indicated on the miter scale. Tighten
base clamp handle and check the height. If it is incor¬
rect, adjust the same as before. Do not change motor
height. Push the saw back and adjust the rear left side
of the table. Hand tighten adjusting nuts.
9. Replace kickback to its proper position.
Incidentally, you do not have to start the table adjust¬
ment with the right rear bolt. You can start with any one
of the bolts, if you find it more convenient. When check¬
ing any adjustments arm must always be locked in base.
