FEATURES
MITER LOCK LEVER
The miter lock lever securely locks the saw at the desired
miter angle.
MITER ThUMBWhEEL
The miter thumbwheel, when used with the miter lock lever
lifted (unlocked), can release the miter table from pre-set
index points. With the thumbwheel spun down (and
released), the miter table moves freely to any desired angle.
With thumb on thumbwheel, push down and hold to over-
ride (bypass) index points; release thumbwheel when close
to desired point and move the lock lever into place with a
click. With the thumbwheel spun up, the miter table will stop
at each index point on the miter scale.
POSITIVE STOPS ON MITER TABLE
Positive stops have been provided at 0°, 15°, 22.5°, 31.6°,
and 45°. The 0°, 15°, 22.5°, 31.6°, and 45° positive stops
have been provided on both the left and right side of the
miter table.
REPEAT-A-CUT™
See Figure 5.
The Repeat-A-Cut™ feature on both the left and right side
miter fences can be used when making repetitive cuts.
Simply mark the fence with a pencil, make the desired
number of cut(s), then wipe the mark off with a soft cloth.
SELF-RETRACTING LOWER BLADE GUARD
The lower blade guard is made of shock-resistant, see-
through plastic that provides protection from each side of
the blade. It retracts over the upper blade guard as the saw
is lowered into the workpiece.
SPINDLE LOCK BUTTON
See Figure 3.
A spindle lock button has been provided for locking the
spindle which keeps the blade in the saw from rotating.
Depress and hold the lock button while installing, changing,
or removing blade only.
SLIDING MITER FENCE
The sliding miter fence on your compound miter saw has
been provided to hold your workpiece securely against when
making all cuts; the left side is larger providing additional
support. It has a sliding feature for clearance of the saw arm
when making bevel or compound cuts.
Loosen the fence screw before attempting to slide the miter
fence. Once the desired position of the miter fence is deter-
mined, tighten the fence screw to secure the sliding fence.
SWITCh TRIGGER
See Figure 4.
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. A lock with
a long shackle up to 9/32 in. diameter may be used. When
the lock is installed and locked, the switch is inoperable.
Store the padlock key in another location.
