Dust cover (Fig. 5)
CAUTION:
Always wear safety goggles even when operating the
machine with the dust cover lowered.
Lower the dust cover to prevent chips from flying.
However, when making bevel cuts, raise it all the way.
Switch action (Fig. 6)
CAUTION:
Before plugging in the machine, always check to see
that the switch trigger actuates properly and returns to
the ''OFF'' position when released.
To start the machine, simply pull the trigger. Release
the trigger to stop. For continuous operation, pull the
trigger and then push in the lock button. To stop the
machine from the locked position, pull the trigger fully,
then release it.
Speed adjusting dial (Fig. 7)
For 4323 only
The machine speed can be infinitely adjusted
between 500 and 3,100 strokes per minute by turning
the adjusting dial. Higher speed is obtained when the
dial is turned in the direction of number 6; lower speed
is obtained when it is turned in the direction of number
1. Refer to the table below to select the proper speed
for the workpiece to be cut. However, the appropriate
speed may differ with the type or thickness of the
workpiece. In general, higher speeds will allow you to
cut workpieces faster but the service life of the blade
will be reduced.
Workpiece to be cut
Wood
Mild steel
Stainless steel
Aluminum
Plastics
CAUTION:
The speed adjusting dial can be turned only as far as
6 and back to 1. Do not force it past 6 or 1, or the
speed adjusting function may no longer work.
Operation (Fig. 8)
CAUTION:
Always hold the machine base flush with the work-
piece. Failure to do so may cause blade breakage,
resulting in a serious injury.
Turn the machine on and wait until the blade attains
full speed. Then rest the machine base flat on the
workpiece and gently move the machine forward
along the previously marked cutting line. When cut-
ting curves, advance the machine very slowly.

Bevel cutting
CAUTION:
• Always be sure that the machine is switched off and
unplugged before tilting the machine base.
• Raise the dust cover all the way before making
bevel cuts.
With the machine base tilted, you can make bevel
cuts at any angle between 0° and 45° (left or right).
(Fig. 9)
Loosen the bolt on the back of the machine base with
the hex wrench. Move the machine base so that the
bolt is positioned in the center of the cross-shaped
slot in the machine base. (Fig. 10)
Tilt the machine base until the desired bevel angle is
obtained. The edge of the motor housing indicates the
bevel angle. Check the contact between the back
edge of the blade and the roller, then tighten the bolt
to secure the machine base. (Fig. 11)
Front flush cuts (Fig. 12)
Loosen the bolt on the back of the machine base with
the hex wrench, then move the machine base all the
way back. Then tighten the bolt to secure the machine
base.
Cutouts
Cutouts can be made with either of two methods A or
B.
A) Boring a starting hole: For internal cutouts without
a lead-in cut from an edge, pre-drill a starting hole
12 mm or more in diameter. Insert the blade into
this hole to start your cut. (Fig. 13)
B) Plung cutting: You need not bore a starting hole or
make a lead-in cut if you carefully do as follows.
1. Tilt the machine up on the front edge of the
base, with the blade point positioned just
above the workpiece surface. (Fig. 14)
2. Apply pressure to the machine so that the front
edge of the base will not move when you
switch on the machine and gently lower the
back end of the machine slowly.
3. As the blade pierces the workpiece, slowly
lower the base of the machine down onto the
workpiece surface.
4. Complete the cut in the normal manner.
Finishing edges (Fig. 15)
To trim edges or make dimensional adjustments, run
the blade lightly along the cut edges.
