FEATURES

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. Sim- ply 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.

SLIDING MITER FENCES

The sliding miter fences provided with this saw help hold the workpiece securely when making most cuts. The sliding feature allows for clearance 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 screw 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 3.

The spindle lock button locks the spindle stopping the blade from rotating. Depress and hold the lock button while install- ing, changing, or removing blade.

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.
