Getting to Know Your Miter Saw
15 Stationary Fence is bolted to the base and
supports the workpiece when the sliding
fence is removed.
16 Base Extensions provide extra support for
the saw, which can be useful when cutting
long workpieces.
17 Miter Detent Plate can be adjusted to set
the accuracy of its detent locations.
18 Miter Detents, are ten slots that allow for
fast and accurate miter cuts at common
miter angles.
19 Miter Scale and Pointer allows you to see
the angle setting before a cut is made. The
pointer rotates with the table and blade
and points to the angle on the miter scale.
20 Miter Lock Knob locks the miter saw table
at any desired miter angle.
21 Miter Detent Override Button locks out
detent action, allowing for micro-adjust-
ments to any miter angle.
22 Table provides workpiece support, rotates
for desired miter cuts, and rotates the
head assembly. The front extended part of
the table is called the miter arm.
23 Rubber Deflector is attached to the bot-
tom of the dust chute and deflects dust
into the chute.
24 Chip Deflector prevents cut-off workpiec-
es from entering the upper guard.
25 Blade is the component that makes cuts
in workpieces. Use only 12" (305 mm) di-
ameter blades with 1" (25.4 mm) diameter
arbor holes.
26 Lower Blade Guard/Lower Guard Lip
helps protect your hands from the spin-
ning blade. It retracts as the blade is low-
ered. Should the guard become jammed
on a workpiece, the lip can be used to
raise the lower guard.
27 Upper Guard covers upper part of the
blade.
