Familiarization

Your miter saw is fully assembled in the carton.

Open the box and lift the saw out by the FIG. 2 convenient lifting handle, as shown in Figure 2.

Place the saw on a smooth, flat surface such as a workbench or strong table.

Examine Figure 4 to become familiar with the saw and its various parts. The section on adjustments will refer to these terms and you must know what and where the parts are.

CAUTION: Pinch hazard. To reduce the risk of injury, keep thumb underneath the

operating handle when pulling the handle

down. The lower guard will move up as the operating handle is pulled down, which could cause pinching. The operating handle is placed close to the guard for special cuts.

Press down lightly on the operating handle and pull out the lock down pin. Gently release the downward pressure and hold the operating handle, allowing it to rise to its full height. Use the lock down pin when carrying the saw from one place to another. Always use the lifting handle to transport the saw, or use the hand indentations shown in Figure 4.

Bench Mounting

Holes are provided in all 4 feet to facilitate bench mounting, as shown in Figure 4. (Two different-sized holes are provided to accommodate different sizes of screws. Use either hole, it is not necessary to use both.) Always mount your saw firmly to a stable surface to prevent movement. To enhance the tool’s portability, it can be mounted to a piece of 1/2" (12.7 mm) or thicker plywood which can then be clamped to your work support or moved to other job sites and reclamped.

NOTE: If you elect to mount your saw to a piece of plywood, make sure that the mounting screws don’t protrude from the bottom of the wood. The plywood must sit flush on the work support. When clamping the saw to any work surface, clamp only on the clamping bosses where the mounting screw holes are located. Clamping at any other point will interfere with the proper operation of the saw.

CAUTION: To prevent binding and inaccuracy, be sure the mounting surface is not warped or otherwise uneven. If the saw rocks on the surface, place a thin piece of material under one saw foot until the saw sits firmly on the mounting surface.

IMPORTANT SAFETY INSTRUCTIONS

Changing or Installing a New Saw Blade (Fig. 3)

WARNING: To reduce the risk of injury, turn unit off and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

CAUTION:

• Never depress the spindle lock button while the blade is under power or coasting.

•Do not cut ferrous metal (containing iron or steel) or masonry or fiber cement product with this miter saw.

Removing the Blade (Fig. 3)

1.Unplug the saw.

2.Raise the arm to the upper position and raise the lower guard (A) as far as possible.

3.Loosen, but do not remove guard bracket screw (B) until the bracket can be raised far enough to access the blade screw (E). Lower guard will remain raised due to the position of the guard bracket screw.

4.Depress the spindle lock button (C) while carefully rotating the saw blade by hand until the lock engages.

5.Keeping the button depressed, use the other hand and the wrench provided (D) to loosen the blade screw. (Turn clockwise, left-hand threads.)

6.Remove the blade screw (E), outer clamp washer (F), blade (G) and blade adapter (H), if used. The inner clamp washer (I) may be left on the spindle.

NOTE: For blades with a blade hole of 5/8" (15.88 mm), the 1" (25.4 mm) blade adapter (H) is not used.

Installing a Blade (Fig. 3)

1.Unplug the saw.

2.With the arm raised, the lower guard held open and the guard bracket raised, place the blade on the spindle, onto the blade adapter (if using a blade with a 1" [25.4 mm] diameter blade hole) and against the inner blade clamp with the teeth at the bottom of the blade pointing toward the back of the saw.

3.Assemble the outer clamp washer onto the spindle.

4.Install the blade screw and, engaging the spindle lock, tighten the screw firmly with wrench provided (turn counterclockwise, left-hand threads).

NOTE: When using blades with a 5/8" (15.88 mm) diameter blade hole, the blade adapter will not be used and should be stored in a safe place for future use. The separate blade adapter is not available on all models.

5.Return the guard bracket to its original position and firmly tighten the guard bracket screw to hold bracket in place.

WARNING:

•The guard bracket must be returned to its original position and the guard bracket screw tightened before activating the saw.

•Failure to do so may allow the guard to contact the spinning saw blade resulting in damage to the saw and severe personal injury.

Transporting the Saw

WARNING: To reduce the risk of injury, turn unit off and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

WARNING: To reduce the risk of serious personal injury, ALWAYS lock the rail lock knob, miter lock handle, bevel lock handle, lock down pin and fence adjustment knobs before transporting saw.

In order to conveniently carry the miter saw from place to place, a lifting handle has been included on the top of the saw arm and hand indentations in the base, as shown in Figure 4.
