OPERATING INSTRUCTIONS
Installing or removing saw blade (Fig. 1 & 2)
CAUTION:
• Always be sure that the tool is switched off and
unplugged before installing or removing the blade.
• Always clean out all chips or foreign matter adhering to
the blade and/or blade holder. Failure to do so may
cause insufficient tightening of the blade, resulting in a
serious injury.
To install the blade, loosen the bolt on the blade holder
with the hex wrench. With the blade teeth facing forward,
insert the blade into the blade holder as far as it will go.
Make sure that the back edge of the blade fits into the
roller. Then tighten the bolt to secure the blade.
To remove the blade, follow the installation procedures in
reverse.
NOTE:
Occasionally lubricate the roller.
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.

Hex wrench storage (Fig. 3)
When not in use, the hex wrench can be conveniently
stored as shown in Fig. 3.
Dust cover (Fig. 4)
CAUTION:
Always wear safety goggles even when operating the tool
with the dust cover lowered.
Lower the dust cover to prevent chips from flying. How-
ever, when making bevel cuts, raise it all the way.
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 trig-
ger 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.
Applications
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.
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)
