CAUTION:
• Firmly tighten the knob clockwise so that the carriage
will not move during operation. Insufficient tightening
may cause unexpected kickback of the blade. Possible
serious PERSONAL INJURY may result.
2. Slide (push) cutting (cutting wide workpieces)
(Fig. 43)
Loosen the knob counterclockwise so that the carriage
can slide freely. Secure the workpiece with the vise. Pull
the carriage toward you fully. Switch on the tool without
the blade making any contact and wait until the blade
attains full speed. Press down the handle and PUSH
THE CARRIAGE TOWARD THE GUIDE FENCE AND
THROUGH THE WORKPIECE. When the cut is com-
pleted, 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:
• Whenever performing the slide cut, FIRST PULL THE
CARRIAGE TOWARD YOU FULLY and press down the
handle to the fully lowered position, then PUSH THE
CARRIAGE TOWARD THE GUIDE FENCE. NEVER
START THE CUT WITH THE CARRIAGE NOT FULLY
PULLED TOWARD YOU. If you perform the slide cut
without pulling the carriage fully or if you perform the
slide cut toward your direction, the blade may kickback
unexpectedly with the potential to cause serious PER-
SONAL INJURY.
• Never perform the slide cut with the handle locked in
the lowered position by pressing the stopper pin.
• Never loosen the knob which secures the carriage
while the blade is rotating. This may cause serious
injury.
3. Mitre cutting
Refer to the previously covered "Adjusting the miter
angle".
4. Bevel cut (Fig. 44)
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 with a vise. Make sure the carriage is pulled all the
way back toward the operator. 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 and PUSH THE CARRIAGE TOWARD
THE GUIDE FENCE 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.
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.
• 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 down the handle, apply pressure in par-
allel with the blade. If a force is applied perpendicularly
to the turn base or if the pressure direction is changed
during a cut, the precision of the cut will be impaired.
• Always set the sub-fence to the left position when per-
forming left bevel cuts.
5. 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.
Miter angle
Left and Right 45°
Left 47°
Right 52°
At the miter angle of left 45° and bevel angle of left
45°, workpieces up to 66 mm high and 170 mm wide
can be cut.
At the miter angle of right 45° and bevel angle of left 45°,
workpieces up to 66 mm high and 215 mm wide can be
cut.
At the miter angle of left and right 45° and bevel angle of
right 45°, workpieces up to 45 mm high and 215 mm
wide can be cut.
When performing compound cutting, refer to "Press cut-
ting", "Slide cutting", "Miter cutting" and "Bevel cut" expla-
nations.
6. Cutting aluminum extrusion
When securing aluminum extrusions, use spacer blocks
or pieces of scrap as shown in Fig. 45 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. (Fig. 46)
7. Wood facing (Fig. 47)
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 and 6 mm screws.
See the figure concerning the dimensions for a sug-
gested wood facing.
CAUTION:
• Use straight wood of even thickness as the wood fac-
ing.
• When cutting workpieces from 115 mm to 120 mm
high, use a wood facing to prevent a portion of the
workpiece near the guide fence from being left uncut.
Example:
When cutting workpieces 120 mm high, use a wood fac-
ing with the following thickness.
Miter angle
0°
Left and Right 45°
Right 52°
Bevel angle
Left and Right 0° – 45°
Left 0° – 45° and Right 0° – 40°
Left 0° – 30° and Right 0° – 45°
Thickness of wood facing
Over 20 mm
Over 15 mm
Over 15 mm
