MACHINE USE

TYPICAL OPERATIONS AND HELPFUL HINTS

WARNING: Cuttinghead must return quickly to the full up position. Sluggish or incomplete return of the cuttinghead will effect lower guard operation possibly resulting in personal injury.

1.Before cutting, make certain that the cutting arm and table are at their correct settings and firmly locked in place.

2.Place the workpiece on the table and hold or clamp it firmly against the fence. The optional clamp (A) Fig. 30 can also be used on the right side of the machine.

3. WARNING: If the position or size of the workpiece causes your hand to be in the “Hazard Zone”, use the work clamp to secure the workpiece. Keep your hands out of the “Hazard Zone”.

4.For best results, cut at a slow, even cutting rate.

5.Never attempt freehand cutting (wood that is not held firmly against the fence and table).

AUXILIARY WOOD FENCE

WARNING: When performing multiple or repetitive operations that result in small cut-off pieces (one inch or less), the saw blade can catch the cut-off pieces and project them out of the machine or into the blade guard and housing, causing damage or injury. To limit the risk, mount an auxiliary wood fence on your saw (Fig. 31).

Holes are provided in the fence to attach an auxiliary fence (A) Fig.

31.This auxiliary fence is constructed of straight wood approximately 1/2 in. thick by 3 in. high by 20 in. long.

NOTE: The auxiliary fence (A) is used ONLY with the saw blade in the 0° bevel position (90° to the table). When you bevel cut (blade tilted), remove the auxiliary fence.

LASER USE AND ADJUSTMENT

The battery-operated laser unit (AA batteries not included) is mounted in a housing that is fitted into the upper blade guard of the miter saw (Fig. A). (To insert the batteries, remove the screw (C) Fig. B, and slide the battery cover (D) from the handle.) The laser projects a beam of light downward. This beam of light produces a red line-of-cut indicator, where the saw blade will cut the workpiece. The laser unit is aligned at the factory and secured in place. A test cut has been made with each saw to verify the laser setup. If your saw becomes misaligned or you desire additional precision, use the following guidelines to fine tune your laser miter saw.

HOW TO CHECK LASER ALIGNMENT

Make sure the saw is set to 0 degrees miter and bevel and clamp a 2 in. x 4 in. board on the saw. Create a partial/test cut in the workpiece (Fig. C). Turn the laser “ON/OFF” switch (A) Fig. B) to the “ON” position. Leave the workpiece clamped in place for the remainder of the adjustment.

WARNING: Place and lock a padlock with a 3/16 in. shackle

(B)Fig. B through the hole in the trigger switch to prevent accidental motor startup.The padlock MUST remain in place during the adjustment procedure.

The laser line is properly positioned when the beam of light falls on the cut created by the blade (Fig. D).

TO CHECK FOR VERTICAL ALIGNMENT

1.The vertical alignment is set correctly when the line does not move horizontally (sideways) as the cutting head is raised and lowered. If the vertical alignment is correct, disregard this section and move to “To set kerf adjustment”.

2.If the vertical alignment is not correct, turn the kerf adjustment screw one half turn, clockwise. Remove the screws on both sides of the laser unit cover (Fig. A). Remove the cover.

3.Use the 1/8 in. hex wrench to turn the vertical alignment set
