To Reduce the Risk of Injury From Jams, Slips Or Thrown Pieces

Use Only Recommended Acces- sories. (See “Accessory” section within.) Consult this owner’s manual for recommended accessories. Fol- low the instructions that come with the accessories. The use of improper accessories may cause risk of injury to persons.

Choose the right 12-inch diameter blade for the saw and the material you plan to cut.

Make sure the blade is sharp, undamaged and properly aligned. With the saw unplugged, push the power head all the way down. Hand spin the blade and check for clear- ance. Tilt the power head to 45 degrees left and right bevel and repeat the check. If the blade hits anything, make the adjustments shown in “Alignment (Adjustments)”

section.

Make sure the blade, arbor collars and laser system are clean.

Make sure the arbor collars' and laser discs’ recessed sides are fac- ing the blade.

Using the 1/4” hex end of combina- tion wrench (supplied) or a 1/2-inch box end wrench, make sure the left hand thread arbor screw is firmly tightened counterclockwise.

Make sure all clamps and locks are tight and there is no excessive play in any parts.

Keep Work Area Clean. Cluttered areas and benches invite accidents. Floor must not be slippery.

To reduce the risk of burns or other fire damage, never use the saw near flammable liquids, vapors or gases.
