screws (Fig. E). If you move the cutterhead from the raised to
the lowered position and the laser line moves horizontally away
from the blade, turn the vertical alignment set screw clockwise to
correct. If the laser line moves horizontally toward the blade, turn
the vertical alignment set screw counter-clockwise to correct.
(Fig. F)
4. Reinstall the cover removed in step 2.
Never turn the brass hex nut in Fig. E.
CAUTION:
TO SET KERF ADJUSTMENT
1. Use the 1/8 in. hex wrench (A) Fig. H to turn the kerf adjustment
screw that sets the laser line to either side of the test cut (Fig.
G). To adjust the line, turn the kerf adjustment screw counter-
clockwise to move the line toward the blade and clockwise to
move the line away from the blade.
2. Remove the padlock. The laser miter saw is ready for normal use.
LASER MAINTENANCE
For best laser performance, perform the following maintenance
regularly:
1. Carefully clean sawdust from each laser lens (A) Fig. I with a
cotton swab (B). Do not use solvents of any kind since they may
damage the lens. Avoid touching sharp points of the saw blade
with your hands or fingers. Dust build-up can block the laser and
prevent it from accurately indicating the line-of-cut.
2. Remove the blade from the saw and clean pitch build-up from
the blade (Fig. J) Pitch build-up can block the laser and prevent
it from accurately indicating the line-of-cut.
GENERAL CUTTING OPERATIONS
1. Your machine has the capacity to cut standard 2 x 4's, lying flat
or on edge, at the 45° right and left miter angles (Fig. A1 & A2).
2. A standard 2 x 6 can be cut in the 90° straight cut-off position in
one pass (Fig. A3).
3. Cutting a standard 4 x 4 can be accomplished with one pass
(Fig. A4).
4. This machine has the capacity to accurately cut crown
moldings and other bevel-type cuts (Fig. A5).
5. Cutting various sizes of plastic pipe is an easy job with this
machine (Fig. A6). Material must be CLAMPED OR HELD
FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING.
is extremely important when making angle cuts.
BODY AND HAND POSITION (FIG. A7 & A8)
Proper positioning of your body and hands when operating the miter
saw will make cutting easier, more accurate and safer. (Fig. A7)
Never place hands near cutting area. Place hands no closer than 6 in.
(152.4 mm) from the blade. Hold the workpiece tightly to the table and
the fence when cutting. Keep hands in position until the trigger has
been released and the blade has completely stopped. ALWAYS
MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS SO
THAT YOU CAN CHECK THE PATH OF THE BLADE. DO NOT
CROSS HANDS, AS SHOWN IN FIGURE A8. Keep both feet firmly
on the floor and maintain proper balance. As you move the miter arm
left and right, follow it and stand slightly to the side of the saw blade.

CUTTING ALUMINUM
Aluminum extrusions such as used for making aluminum screens
and storm windows can easily be cut with your compound miter saw
when fitted with a blade recommended for this material. The blade
supplied with this saw is not recommended for cutting aluminum.
When cutting aluminum extrusions, or other sections that can be cut
with a saw blade and are within the capacity of the machine, position
the material so the blade is cutting through the smallest
cross-section (Fig. 32). The wrong way to cut aluminum angles is
illustrated in Fig. 33. Be sure to apply a stick wax to the blade
before cutting aluminum stock. This stick wax is available at most
industrial mill supply houses. The wax provides proper lubrication
and keeps chips from adhering to the blade.
NEVER APPLY LUBRICANT TO THE BLADE WHILE THE
MACHINE IS RUNNING.
