Switch action (Fig. 5)
CAUTION:
Before plugging in the tooltool, always check to see that the switch trigger actuates properly and returns to the "OFF"
position when released.
To start the tool, 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 tool from the locked position, pull the trigger fully, then release it.
Selecting the cutting action (Fig. 6)
This tool can be operated with an orbital or a straight line (up and down) cutting action. The orbital cutting action
thrusts the blade forward on the cutting stroke and greatly increases cutting speed.
To change the cutting action, just turn the cutting action changing lever to the desired cutting action position. Refer to
the table below to select the cutting action.
Position
O Straight line cutting action
I Small orbit cutting action
II Medium orbit cutting action
III Large orbit cutting action
Speed adjusting dial (Fig. 7)
The tool 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 ser-
vice 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 tool base flush with the workpiece. Fail-
ure to do so may cause blade breakage, resulting in a
serious injury.
Turn the tool on and wait until the blade attains full speed.
Then rest the tool base flat on the workpiece and gently
move the tool forward along the previously marked cut-
ting line. When cutting curves, advance the tool very
slowly.

Applications
Bevel cutting
CAUTION:
• Always be sure that the tool is switched off and
unplugged before tilting the tool base.
• Raise the dust cover all the way before making bevel
cuts.
With the tool 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 tool base with the hex
wrench. Move the tool base so that the bolt is positioned
in the center of the cross-shaped slot in the tool base.
(Fig. 10)
Tilt the tool 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 tool
base. (Fig. 11)
Front flush cuts (Fig. 12)
Loosen the bolt on the back of the tool base with the hex
wrench, then move the tool base all the way back. Then
tighten the bolt to secure the tool 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) Plunge cutting: You need not bore a starting hole or
make a lead-in cut if you carefully do as follows.
1. Tilt the tool up on the front edge of the base, with
the blade point positioned just above the work
piece surface. (Fig. 14)
2. Apply pressure to the tool so that the front edge of
the base will not move when you switch on the
tool and gently lower the back end of the tool
slowly.
3. As the blade pierces the workpiece, slowly lower
the base of the tool down onto the workpiece sur-
face.
4. Complete the cut in the normal manner.
