Familiarization

Your miter saw is fully assembled in the carton. Open the box and lift the saw out by the convenient carrying 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 adjus- tments 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 handle when pulling the handle down. The lower guard will move up as the handle is pulled down which could cause pinching. The 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 arm 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 carrying handle to transport the saw or 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 dif- ferent 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 surely 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 serious personal injury, turn off the tool and disconnect it from the power source before attempting to move it, change accessories or make any adjustments accept as written in laser adjustment instructions.

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

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. 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

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” (25.4mm) 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 blade clamp 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.

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 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.

ADJUSTMENTS

WARNING: To reduce the risk of serious personal injury, turn off the tool and disconnect it from the power source before attempting to move it, change accessories or make any adjustments accept as written in laser adjustment instructions.

NOTE: Your miter saw is fully and accurately adjusted at the factory at the time of manufacture. If readjustment due to shipping and handling or any other reason is required, follow the steps below to adjust your saw.

Once made, these adjustments should remain accurate. Take a little time now to follow these directions carefully to maintain the accuracy of which your saw is capable.

MITER SCALE ADJUSTMENT (FIG. 5)

Place a square against the saw’s fence and blade, as shown. (Do not touch the tips of the blade teeth with the square. To do so will cause an inaccurate measurement.) Loosen the miter lock handle and swing the miter arm until the miter latch locks it at the 0 miter position. Do not tighten the lock handle. If the saw blade is not exactly perpendicular to the fence, loosen the four screws that hold the miter scale to the base and move the scale left or right until the blade is perpendicular to the fence, as measured with the square. Retighten the four screws. Pay no attention to the reading of the miter pointer at this time.

MITER POINTER ADJUSTMENT (FIG. 6, 7)

Loosen the miter lock handle to move the miter arm to the zero position. With the miter lock handle loose allow the miter latch to snap into place as you rotate the miter arm to zero. Observe the pointer and miter scale shown in Figure 6. If the pointer does not indicate exactly zero, loosen the screw holding the pointer in place, reposition the pointer and tighten the screw.

BEVEL SQUARE TO TABLE ADJUSTMENT (FIG. 8)

To align the blade square to the table, lock the arm in the down position. Place a square against the blade and table taking care to have the square not touch a blade tooth. Loosen the bevel lock handle and ensure the bevel latch has firmly snapped into place at 0º. If the saw blade is not exactly perpendicular to the table, loosen the three nuts which hold the bevel detent plates to the table. Adjust the center nut to allow slight drag between it and the table. Gently tap the motor or the belt cover to move the upper assembly until the blade is square to the table.
