MITER POINTER ADJUSTMENT (FIG. 5)
Unlock the miter lock handle to move the miter arm to the zero position. With the miter lock
handle unlocked, allow the miter latch to snap into place as you rotate the miter arm to zero.
Observe the miter pointer and miter scale shown in Figure 5. If the pointer does not indicate
exactly zero, loosen the miter pointer screw holding the pointer in place, reposition the pointer
and tighten the screw.
BEVEL SQUARE TO TABLE ADJUSTMENT (FIG. 4, 6, 11)
To align the blade square to the table, lock the arm in the down position with the lock down
pin. Place a square against the blade, ensuring the square is not on top of a tooth. Loosen
the bevel lock knob and ensure the arm is firmly against the 0° bevel stop. Rotate the 0° bevel
adjustment screw with the 1/2" (13 mm) blade wrench as necessary so that the blade is at 0°
bevel to the table, as measured with the square.

BEVEL POINTERS (FIG. 6)
If the bevel pointers do not indicate zero, loosen each screw 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 45º RIGHT AND LEFT ADJUSTMENT (FIG. 4, 6)
To adjust the right 45° bevel angle, loosen the bevel lock knob and pull the 0° bevel stop to
override the 0° bevel stop. When the saw is fully to the right, if the bevel pointer does not
indicate exactly 45°, turn the left 45° bevel adjustment screw with the 1/2" (13 mm) blade
wrench until the bevel pointer indicates 45°.
To adjust the left 45° bevel stop, first loosen the bevel lock knob and tilt the head to the left.
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 33.9°) (FIG. 4, 6)
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. Loosen the bevel lock knob
and tilt the head fully to the left. If the bevel pointer does not indicate exactly 22.5°, turn the
crown adjustment screw contacting the pawl with a 7/16" (10 mm) 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 to override the 0° bevel stop. When the saw is fully to the
FIG. 11
MITER LOCK HANDLE
right, if the bevel pointer does not indicate exactly 22.5°, turn the crown adjustment screw
contacting the pawl with a 7/16" (10 mm) wrench until the bevel pointer indicates exactly
22.5°.
FENCE ADJUSTMENT (FIG. 4)
In order that the saw can bevel to many bevel positions, one of the fences may have to be
adjusted to provide clearance. To adjust each fence, loosen the fence adjustment knob and
slide the fence outward. Make a dry run with the saw turned off and check for clearance.
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. Tighten the fence adjustment
knob securely. When the bevel operations are complete, don't forget to relocate the fence.
For certain cuts, it may be desirable to bring the fences closer to the blade. To use this feature,
back the fence adjustment knobs out two turns and move the fences closer to the blade past
the normal limit, then tighten the fence adjustment knobs to keep the fences in this location.
When using this feature, 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. If you notice that they are
becoming clogged, use a brush or some low pressure air to clear the guide grooves.
GUARD ACTUATION AND VISIBILITY (FIG. 4)
CAUTION: Pinch hazard. To reduce the risk of injury, keep thumb underneath the operating
handle when pulling the handle down. The lower guard will move up as the operating handle
is pulled down, which could cause pinching.
The lower guard 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.
NOTE: Certain special cuts of large material will require that you manually raise the guard.
Refer to Cutting Large Material under Special Cuts.
The front section of the guard is louvered for visibility while cutting. Although the louvers
dramatically reduce flying debris, they are openings in the guard and safety glasses should
be worn at all times.
KERF PLATE ADJUSTMENT (FIG. 4)
To adjust the kerf plates, 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. 4)
Periodically check the rails for any play or clearance. The right rail can be adjusted with the
set screw shown in Figure 4. To reduce clearance, use a 4 mm hex wrench and rotate the
set screw clockwise gradually while sliding the saw head back and forth. Reduce play while
maintaining minimum slide force.
MITER LOCK ADJUSTMENT (FIG. 12)
The miter lock rod should be adjusted if the
table of the saw can be moved when the
miter lock handle is locked (down). To adjust
the miter lock, put the miter lock handle in the
unlocked (up) position. Using a 1/2" (13 mm)
open end wrench, loosen the lock nut on
the miter lock rod (Fig. 12). Using a slotted
screwdriver, tighten the miter lock rod by
turning it clockwise as shown in Figure 12.
Turn the lock rod until it is snug, then turn
