The safe use of this product requires an understanding of the information on the tool and in this operator’s manual as well as a knowledge of the project you are attempting. Before use of this product, familiarize yourself with all operating features and safety rules.

12 IN. BLADE

A 12 in. carbide tooth blade is included with your compound miter saw. It will cut materials up to 9-1/4 in. wide, depending upon the angle at which the cut is being made.

15 AMP MOTOR

This saw has a powerful 15 amp motor with sufficient power to handle tough cutting jobs. It is made with all ball bearings, and has externally accessible brushes for ease of servicing.

BLADE WRENCH STORAGE

See Figure 1.

A blade wrench is packed with the saw. One end of the wrench is a phillips screwdriver and the other end is a hex key. Use the hex key end when installing or removing blade and the phillips end when removing or loosening screws. A storage area for the blade wrench is located in the saw’s base.

BEVEL LOCK LEVER

The bevel lock lever securely locks your compound miter saw at desired bevel angles. Pulling the lever forward will release the saw allowing the blade to be tilted either left or right for bevel cuts. Pushing the lever back will lock the saw in place.

BEVEL STOP PIN

The bevel stop pin has two positions:

1.Override (pin pulled completely out) and turn (rotate) for bevel stops

2.The 0° - 48° position for crown molding (pin pushed in)

CARRYING HANDLE

See Figure 2.

For convenience when carrying or transporting your miter saw from one place to another, a carrying handle has been provided on top of the saw arm.

To transport: turn off and unplug saw, lower saw arm and lock in down position (lock pin pushed in), lock bevel and miter lock levers.

ELECTRIC BRAKE

An electric brake quickly stops blade rotation after the switch trigger is released.

LASER GUIDE

For more accurate cuts, a laser guide is included with your miter saw. When used properly, the laser guide makes accurate, precision cutting simple and easy.

MITER LOCK LEVER

The miter lock lever securely locks the saw at the desired miter angle.

MITER SCALE

The miter scale has index points provided at 0°, 15°, 22.5°, 31.6°, and 45°.
