22.5° BEVEL PAWLS (FIG. 12)
Your saw is equipped to rapidly and accurately set a 22.5° bevel, left
or right. The 22.5° bevel pawl (a2) can be rotated to contact the crown
adjustment screw (zz).
RAIL LOCK KNOB (FIG. 1A)
The rail lock knob (g) allows you to lock the saw head firmly to keep it
from sliding on the rails (j). This is necessary when making certain cuts
or when transporting the saw.
GROOVING STOP (FIG. 1B)
The grooving stop (bb) allows the depth of cut of the blade to be
limited. The stop is useful for applications such as grooving and tall
vertical cuts. Rotate the grooving stop forward and adjust the depth
adjustment screw (aa) to set the desired depth of cut. To secure the
adjustment, tighten the wing nut (z). Rotating the grooving stop to
the rear of the saw will bypass the grooving stop feature. If the depth
adjustment screw is too tight to loosen by hand, the provided blade
wrench (cc) can be used to loosen the screw.
LOCK DOWN PIN (FIG. 1A)
WARNING:
The lock down pin should be used ONLY when
carrying or storing the saw. NEVER use the lock down pin
for any cutting operation.
To lock the saw head in the down position, push the saw head down,
push the lock down pin (l) in and release the saw head. This will hold
the saw head safely down for moving the saw from place to place. To
release, press the saw head down and pull the pin out.
SLIDE LOCK LEVER (FIG. 13, 23)
The slide lock lever (a6) places the saw in a position to maximize cutting
of base molding when cut vertically as shown in figure 23.
Adjustment
Your mitre saw is fully and accurately adjusted at the factory at the time
of manufacture. If readjustment due to shipping and handling or any
other reason is required, follow the instructions below to adjust your
saw. Once made, these adjustments should remain accurate.
MITRE SCALE ADJUSTMENT (FIG. 11, 14)
1. Unlock the mitre lock handle (u) and swing the mitre arm until the
mitre latch button (v) locks it at the 0° mitre position. Do not lock
the mitre lock handle.
2. Place a square against the saw’s fence and blade, as shown. (Do
not touch the tips of the blade teeth with the square. To do so will
cause an inaccurate measure ment.)
3. If the saw blade is not exactly perpendicular to the fence, loosen
the four screws (ww) that hold the mitre scale (s) and move the
mitre lock handle and the scale left or right until the blade is
perpendicular to the fence, as measured with the square.
4. Retighten the four screws. Pay no attention to the reading of the
mitre pointer (uu) at this time.
MITRE POINTER ADJUSTMENT (FIG. 11)
1. Unlock the mitre lock handle (u) to move the mitre arm to the zero
position.
2. With the mitre lock handle unlocked, allow the mitre latch to snap
into place as you rotate the mitre arm to zero.
3. Observe the mitre pointer (uu) and mitre scale (s) shown in
figure 11. If the pointer does not indicate exactly zero, loosen the
mitre pointer screw (v v) holding the pointer in place, reposition the
pointer and tighten the screw.
BEVEL SQUARE TO TABLE ADJUSTMENT (FIG. 1A, 1B, 12, 15)
1. To align the blade square to the table, lock the arm in the down
position with the lock down pin (l).
2. Place a square against the blade, ensuring the square is not on top
of a tooth.
3. Loosen the bevel lock knob (ee) and ensure the arm is firmly
against the 0° bevel stop.
4. Rotate the 0° bevel adjustment screw (a5) with the 13 mm (1/2")
blade wrench (cc) as necessary so that the blade is at 0° bevel to
the table.
BEVEL POINTER ADJUSTMENT (FIG. 12)
If the bevel pointers (yy) do not indicate zero, loosen each screw (xx)
that holds each bevel pointer in place and move them as necessary.
Ensure the 0° bevel is correct and the bevel pointers are set before
adjusting any other bevel angle screws.
BEVEL STOP 45° RIGHT AND LEFT ADJUSTMENT (FIG. 1B, 12)
To adjust the right 45° bevel stop:
1. Loosen the bevel lock knob (ee) and pull the 0° bevel stop (ff) to
override the 0° bevel stop.
2. When the saw is fully to the right, if the bevel pointer (yy) does not
indicate exactly 45°, turn the left 45° bevel adjustment screw (a4)
with the 13 mm (1/2") blade wrench (cc) until the bevel pointer
indicates 45°.
To adjust the left 45° bevel stop:
1. Loosen the bevel lock knob and tilt the head to the left.
2. If the bevel pointer does not indicate exactly 45°, turn the right 45°
bevel adjustment screw until the bevel pointer reads 45°.
ADJUSTING THE BEVEL STOP TO 22.5° (OR 30°) (FIG. 1B, 12)
NOTE:
Adjust the bevel angles only after performing the 0° bevel angle
and bevel pointer adjustment.
To set the left 22.5° bevel angle, flip out the left 22.5° bevel pawl (a2).
Loosen the bevel lock knob (ee) and tilt the head fully to the left. If
the bevel pointer (yy) does not indicate exactly 22.5°, turn the crown
adjustment screw (zz) contacting the pawl with a 10 mm (7/16") wrench
until the bevel pointer reads 22.5°.
To adjust the right 22.5° bevel angle, flip out the right 22.5° bevel pawl.
Loosen the bevel lock knob and pull the 0° bevel stop (ff) to override
the 0° bevel stop. When the saw is fully to the right, if the bevel pointer
does not indicate exactly 22.5°, turn the crown adjustment screw
contacting the pawl with a 10 mm (7/16") wrench until the bevel pointer
indicates exactly 22.5°.
FENCE ADJUSTMENT (FIG. 1A)
The upper part of the fence can be adjusted to provide clearance,
allowing the saw to bevel to a full 49° both left and right.
1. To adjust each fence (n), loosen the fence adjustment knob (m) and
slide the fence outward.
2. Make a dry run with the saw turned off and check for clearance.
3. Adjust the fence to be as close to the blade as practical to provide
max imum workpiece support, without interfering with arm up and
down movement.
4. Tighten the fence adjustment knob securely.
5. When the bevel operations are complete, relocate the fence.
For certain cuts, it may be desirable to bring the fences closer to the
blade. To do so, back the fence adjustment knobs (m) out two turns
and move the fences closer to the blade past the normal limit, then
tighten the fence adjustment knobs. Make a dry cut first to ensure the
blade does not contact the fences.
NOTE:
The tracks of the fences can become clogged with sawdust.
Use a brush or some low pressure air to clear the guide grooves.
GUARD ACTUATION AND VISIBILITY (FIG. 1A)
The lower guard (a) on your saw has been designed to automatically
uncover the blade when the arm is brought down and to cover the
blade when the arm is raised.
The guard can be raised by hand when installing or removing saw
blades or for inspection of the saw. NEVER RAISE THE LOWER
GUARD MANUALLY UN LESS THE BLADE IS STOPPED.
KERF PLATE ADJUSTMENT (FIG. 1A)
To adjust the kerf plates (w), loosen the screws holding the kerf plates
in place. Adjust so that the kerf plates are as close as possible without
interfering with the blade’s movement.
If a zero kerf width is desired, adjust the kerf plates as close to each
other as possible. They can now be cut slowly with the saw blade to
give the smallest gap possible between the blade and the kerf plates.
RAIL GUIDE ADJUSTMENT (FIG. 1A)
Regularly check the rails (j) for play or clearance.
The right rail can be adjusted with the set screw (h). To reduce
clearance, use a 4 mm hex wrench and rotate the set screw clockwise
gradually while sliding the saw head back and forth.
