disconnect machine from power source before installing and
removing accessories, before adjusting or changing set-ups
or when making repairs. Be sure the trigger switch is in the OFF
position. An accidental start-up can causeinjury.
Mitre Control (Fig.A1, H)
The mitre lock handle
21
and mitre latch button
5
allow you to mitre your
saw to 60° right and 50° left. To mitre the saw, lift the mitre lock handle,
push the mitre latch button and set the mitre angle desired on the mitre
scale
19
. Push down on the mitre lock handle to lock the mitreangle.
Override the mitre latch button by unlocking the mitre lock knob and
pushing the mitre detent override
36
downward. To exit the override, push
the mitre detent overrideupward.
Bevel Lock Knob (Fig. A2)
The bevel lock allows you to bevel the saw 49° left or right. To adjust the
bevel setting, turn the bevel lock knob
31
counterclockwise. The saw head
bevels easily to the left or to the right once the 0° bevel override knob is
pulled. To tighten, turn the bevel lock knobclockwise.
0° Bevel Override (Fig. A2)
The 0° bevel stop
32
override allows you to bevel the saw to the right past
the 0°mark.
When engaged, the saw will automatically stop at 0° when brought up
from the left. To temporarily move past 0° to the right, pull the bevel lock
knob
31
. Once the knob is released, the override will be reengaged. The
bevel lock knob can be locked out by twisting the knob 180°.
When at 0°, the override locks in place. To operate the override, bevel the
saw slightly to theleft.
45° Bevel Stop Override (Fig.I)
There are two bevel stop override levers, one on each side of the saw.
To bevel the saw, left or right, past 45°, push the 45° bevel override
lever
53
rearward. When in the rearward position, the saw can bevel past
these stops. When the 45° stops are needed, pull the 45° bevel override
leverforward.
Crown Bevel Pawls (Fig.I)
When cutting crown molding laying flat, your saw is equipped to accurately
and rapidly set a crown stop, left or right (refer to Instructions for Cutting
Crown Molding Laying Flat and Using the Compound Features)
The crown bevel pawl
55
can be rotated to contact the crown
adjustmentscrew.
To reverse the crown bevel pawl, remove the retaining screw, the 22.5°
bevel pawl
54
and the 30° crown bevel pawl
55
. Flip the crown bevel
pawl
55
so the 30° text is facing up. Reattach the screw to secure the
22.5° bevel pawl and the crown bevel pawl. The accuracy setting will not
beaffected.
22.5° Bevel Pawls (Fig.I)
Your saw is equipped to rapidly and accurately set a 22.5° bevel, left or right.
The 22.5° bevel pawl
54
can be rotated to contact the crown adjustment
screw
52
.
Rail Lock Knob (Fig. A1)
The rail lock knob
6
allows you to lock the saw head firmly to keep it from
sliding on the rails
9
. This is necessary when making certain cuts or when
transporting thesaw.
Grooving Stop (Fig. A2)
The grooving stop
28
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
27
to set the desired depth of cut. To secure the adjustment, tighten
the wing nut
26
. 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
29
can be used to loosen
thescrew.
Lock Down Pin (Fig. A1)

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
11
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.
