6. Cutting aluminum extrusion
When securing aluminum extrusions, use spacer blocks
or pieces of scrap as shown in Fig. 33 to prevent defor-
mation of the aluminum. Use a cutting lubricant when
cutting the aluminum extrusion to prevent buildup 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.
7. Groove cutting (Fig. 34)
A dado type cut can be made by proceeding as follows:
Adjust the lower limit position of the blade using the
adjusting screw and the stopper arm to limit the cutting
depth of the blade. Refer to "Stopper arm" section
described previously.
After adjusting the lower limit position of the blade, cut
parallel grooves across the width of the workpiece using
a slide (push) cut as shown in the figure. Then remove
the workpiece material between the grooves with a
chisel. Do not attempt to perform this type of cut using
wide (thick) blades or with a dado blade. Possible loss of
control and injury may result.
CAUTION:
• Be sure to return the stopper arm to the original posi-
tion when performing other than groove cutting.
Carrying tool
Make sure that the tool is unplugged. Secure the blade at
0° bevel angle and the turn base at right miter angle fully.
Secure the slide poles after pulling the carriage toward
you fully. Lower the handle fully and lock it in the lowered
position by pushing in the stopper pin. (Fig. 35)
Carry the tool by holding both sides of the tool base as
shown in the figure. If you remove the holders, dust bag,
etc., you can carry the tool more easily. (Fig. 36)
CAUTION:
• Always secure all moving portions before carrying the
tool.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Adjusting the cutting angle
This tool is carefully adjusted and aligned at the factory,
but rough handling may have affected the alignment. If
your tool is not aligned properly, perform the following:
1. Miter angle
Push the carriage toward the guide fence and tighten the
knob to secure the carriage.
Loosen the grip which secures the turn base. Turn the
turn base so that the pointer points 0° on the miter scale.
Then turn the turn base slightly clockwise and counter-
clockwise to seat the turn base in the 0° miter notch.
(Leave as it is if the pointer does not point 0°.) Loosen
the hex bolts securing the guide fence using the socket
wrench. (Fig. 37)
Lower the handle fully and lock it in the lowered position
by pushing in the lock pin. Square the side of the blade
with the face of the guide fence using a triangular rule,
try-square, etc. Then securely tighten the hex bolts on
the guide fence in the order from the left side. (Fig. 38)
Make sure that the pointer indicates 0° on the miter
scale. If the pointer does not indicate 0°, loosen the
screw securing the pointer and adjust the pointer.
(Fig. 39)
2. Bevel angle
1) 0° bevel angle
Push the carriage toward the guide fence and
tighten the knob to secure the slide poles. Lower the
handle fully and lock it in the lowered position by
pushing in the lock pin. Loosen the lever at the rear
of the tool. Make sure that the arm is locked.
(Fig. 40)
Turn the hex bolt on the left side of the arm two or
three revolutions counterclockwise. Turn the hex bolt
on the right side of the arm two or three revolutions
counterclockwise to tilt the blade to the left. (Fig. 41)
Carefully square the side of the blade with the top
surface of the turn base using the triangular rule, try-
square, etc. by turning the hex bolt on the right side
of the arm clockwise. Turn the hex bolt on the left
side of the arm clockwise as far as it will go. Then
tighten the lever securely. (Fig. 42)
Make sure that the two pointers on the arm point to
each 0° on the bevel scale on the arm holder. If they
do not point to 0°, loosen the screws which secure
the pointers and adjust them so that they will point to
0°. (Fig. 43)
2) 45° bevel angle (Fig. 44)
Adjust the 45° bevel angle only after performing 0°
bevel angle adjustment. To adjust left 45° bevel
angle, loosen the lever and tilt the blade 45° to the
left. Make sure that the pointer on the arm holder
points to 45° on the bevel scale on the arm holder. If
the pointer does not point to 45°, turn the left 45°
bevel angle adjusting bolt on the side of the arm
holder until the pointer points to 45°. To adjust right
45° bevel angle, perform the same procedure
described above.
Adjusting for smooth beveling action (Fig. 45)
The hex lock nut holding together the arm and arm
holder has been factory adjusted to assure smooth bev-
eling action and to guarantee precise cutting. Do not
tamper with it. Should looseness develop at the arm and
arm holder connection, tighten the hex lock nut using a
wrench.
