CAUTION:
• Do not apply excessive pressure on the handle when
cutting. Too much force may result in overload of the
motor and/or decreased cutting efficiency. Push down
handle with only as much force as is necessary for
smooth cutting and without significant decrease in
blade speed.
• Gently press down the handle to perform the cut. If the
handle is pressed down with force or if lateral force is
applied, the blade will vibrate and leave a mark (saw
mark) in the workpiece and the precision of the cut will
be impaired.
1. Press cutting (Fig. 41)
Secure the workpiece against guide fence and turn table.
Switch on the tool without the blade making any contact
and wait until the blade attains full speed before lowering.
Then gently lower the handle to the fully lowered position
to cut the workpiece. When the cut is completed, switch
off the tool and WAIT UNTIL THE BLADE HAS COME
TO A COMPLETE STOP before returning the blade to its
fully elevated position.
2. Miter cutting
Refer to the previously covered "Adjusting the miter
angle".
3. Bevel cut (Fig. 42)
Loosen the lever and tilt the saw blade to set the bevel
angle (Refer to the previously covered "Adjusting the
bevel angle"). Be sure to retighten the lever firmly to
secure the selected bevel angle safely. Secure the work-
piece against guide fence and turn table. Switch on the
tool without the blade making any contact and wait until
the blade attains full speed. Then gently lower the handle
to the fully lowered position while applying pressure in
parallel with the blade. When the cut is completed, switch
off the tool and WAIT UNTIL THE BLADE HAS COME
TO A COMPLETE STOP before returning the blade to its
fully elevated position.
CAUTION:
• Always be sure that the blade will move down to bevel
direction during a bevel cut. Keep hands out of path of
saw blade.
6. Wood facing
Use of wood facing helps to assure splinter-free cuts in workpieces. Attach a wood facing to the guide fence using the
holes in the guide fence.
See the figure concerning the dimensions for a suggested wood facing.

• During a bevel cut, it may create a condition whereby
the piece cut off will come to rest against the side of the
blade. If the blade is raised while the blade is still rotat-
ing, this piece may be caught by the blade, causing
fragments to be scattered which is dangerous. The
blade should be raised ONLY after the blade has come
to a complete stop.
• When pressing the handle down, apply pressure paral-
lel to the blade. If the pressure is not parallel to the
blade during a cut, the angle of the blade might be
shifted and the precision of the cut will be impaired.
4. Compound cutting
Compound cutting is the process in which a bevel angle
is made at the same time in which a miter angle is being
cut on a workpiece. Compound cutting can be performed
at angle shown in the table.

When performing compound cutting, refer to "Press cut-
ting", "Miter cutting" and "Bevel cut" explanations.
5. Cutting aluminum extrusion (Fig. 43)
When securing aluminum extrusions, use spacer blocks
or pieces of scrap as shown in the figure to prevent defor-
mation of the aluminum. Use a cutting lubricant when
cutting the aluminum extrusion to prevent build-up of the
aluminum material on the blade.
CAUTION:
• Never attempt to cut thick or round aluminum extru-
sions. Thick aluminum extrusions may come loose dur-
ing operation and round aluminum extrusions cannot
be secured firmly with this tool.
• Never cut aluminum in the table saw mode (bench
mode).
