FEATURES
SLIDE BAR
When unlocked, the saw arm will glide forward and back-
ward the length of the slide bar for cutting various workpiece
widths.
SLIDE LOCK KNOB
The slide lock knob locks and unlocks the sliding feature
of this tool.
SLIDING MITER FENCES
See Figure 4.
The sliding miter fences help hold the workpiece securely
when making most cuts. The sliding feature allows for clear-
ance of the saw blade when making bevel or compound cuts.
Some cuts may require that the sliding fence be removed
completely to avoid interference between the fence and
the blade.
Loosen the fence lock knob before attempting to slide the
fences or lift them for removal. Once the desired position of
the fence is determined, retighten the fence screw securely.
SPINDLE LOCK BUTTON
See Figure 5.
The spindle lock button locks the spindle (keeps the saw
blade from turning). Depress and hold the lock button only
while installing, changing, or removing the saw blade.
SWITCH TRIGGER
See Figures 5 - 6.
To prevent unauthorized use of the compound miter saw,
disconnect it from the power supply and lock the switch in
the OFF position. To lock the switch, install a padlock (not
included) through the hole in the switch trigger and make
certain the switch is inoperable. If the switch is still operable
with the padlock installed, a padlock with a larger shackle
diameter must be used. Store the padlock key in another
location.
THREE-POSITION BEVEL LOCK LEVER
See Figure 7.
The bevel lock lever securely locks the saw into selected
bevel angles.
POSITION 1: (Unlocked/detent disengaged) Allows the
blade to be freely tilted either left or right for custom selec-
tion of bevel cuts.
POSITION 2: (Unlocked/detent engaged) Allows you to
easily find 0°, 15°, 22.5°, 33.9°, and 45° at indexed stops.
POSITION 3: Locks the saw into place at the desired bevel
angle.
BEVEL BYPASS LEVER
See Figure 7.
 In the upright position, the bevel bypass lever will disen-
gage the bevel detents.
 In the downward position, the bevel bypass lever will
engage the detent function.
