Miter Pointer Adjustment (Fig.G)
Unlock the miter lock lever
6
to move the miter arm to the zero position. With the miter lock
lever unlocked, allow the miter arm to snap into place as you rotate the miter arm to zero.
Observe the miter pointer
10
and miter scale
11
. 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.
Miter Lock Adjustment (Fig.G, P)
The miter lock rod
50
should be adjusted if the table of the saw can be moved when the miter
lock lever
6
is locked (down). To adjust the miter lock, put the miter lock handle in the unlocked
(up) position. Using a 1/2" open end wrench, loosen the lock nut
51
on the miter lock rod
50
.
Using a slotted screwdriver, tighten the miter lock rod by turning it clockwise. Turn the lock rod
until it is snug, then turn counterclockwise one turn. To ensure the miter lock is functioning
properly, re-lock the miter lock to a non-detented measurement on the miter scale – for example,
34º – and make sure the table will not rotate. Tighten locknut.

Bevel Square to Table Adjustment (Fig.A,I,Q)
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
6
and ensure the arm is firmly against the 0° bevel stop. Rotate the 0°bevel
adjustment screw
36
Fig.I) with the 1/2" blade wrench as necessary so that the blade is at 0°
bevel to thetable.
Fig. Q
Bevel Pointers (Fig.I)
If the bevel pointer
16
does not indicate zero, loosen the screw
37
that holds it in place and
move the pointer 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.H, I)
There are two bevel stop override levers, one on each side of thesaw.
To adjust the right 45° bevel angle, loosen the bevel lock knob
26
and pull the 0° bevel override
lever
29
to override the 0° bevel stop. When the saw is fully to the right, if the bevel pointer
16
does not indicate exactly 45°, turn the left 45° bevel adjustment screw
35
with the 1/2" blade
wrench until the bevel pointer indicates 45°.
To adjust the left 45° bevel angle, first loosen the bevel lock knob
26
and tilt the head to the
left. If the bevel pointer
16
does not indicate exactly 45°, turn the right 45° bevel adjustment
screw
35
until the bevel pointer reads 45°.
Adjusting the Bevel Stop to 22.5° (or 33.9°) (Fig.H, I)
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
32
. Loosen the bevel lock
knob
26
and tilt the head fully to the left. If the bevel pointer
16
does not indicate exactly 22.5°,
turn the crown adjustment screw
33
contacting the pawl with a 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
32
. Loosen the bevel
lock knob
26
and pull the 0° bevel override lever
29
to override the 0° bevel stop. When the
saw is fully to the right, if the bevel pointer
16
does not indicate exactly 22.5°, turn the crown
adjustment screw
33
contacting the pawl with a 7/16" wrench until the bevel pointer indicates
exactly 22.5°.
Fence Adjustment (Fig.H)
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
53
and
slide the fence
14
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.
Rail Guide Adjustment (Fig.A)
Periodically check the rails for any play or clearance. The right rail can be adjusted with the rail
adjustment screw
23
shown in FigureA. To reduce clearance, use a 4 mm hex wrench and
rotate the rail adjustment screw clockwise gradually while sliding the saw head back and forth.
Reduce play while maintaining minimum slideforce.
OPERATION

WARNING: To reduce the risk of serious personal injury, turn tool off and remove
the battery packs or power supply before transporting, making any adjustments,
cleaning, repairing, or removing/installing attachments or accessories. An accidental
start-up can causeinjury.

WARNING: Always use eye protection. All users and bystanders must wear eye
protection that conforms to ANSI Z87.1 (CAN/CSA Z94.3).

WARNING: To ensure the blade path is clear of obstructions, always make a dry run
of the cut without power before making any cuts on theworkpiece.

WARNING: Install the table extensions to both sides of the saw's base. Refer to
Assembling the Table Extensionssection.
Installing and Removing the Battery Packs (Fig.R)
NOTE: For best results, make sure your battery packs are fullycharged.
To install the battery packs
20
into the tool, align the battery packs with the rails on the side
of the motor housing and slide them in until they are firmly seated in the tool and ensure that
they do not disengage. Insert the dust cover
59
into the corded power supply receptacle
58
in
between thebatteries.
NOTICE: Keep the dust cover in place whenever the corded power supply is not
inuse.
To remove the battery packs from the tool, press the battery release button
53
and firmly
pull the battery packs out. Insert them into the charger as described in the charger section of
thismanual.
