ADJUSTING THE ORBITAL OPERATION
1. This machine employs orbital operation which moves
the blade back and forth, as well as up and down. Set
the change knob shown in Fig. 3 to “O” to minimize
the orbital operation (the blade moves only up and
down). The orbital operation can be selected in 4
steps from “O” to “III”.
2. For the hard material, such as a steel plate, etc.,
decrease the orbital operation. For the soft material,
such as lumber, plastic, etc., increase the orbital
operation to increase work efficiency. To cut the
material accurately, decrease the orbital operation.
ADJUSTING THE BLADE OPERATING SPEED
The blade operating speed can be adjusted within a
range of 0 to 3,000/min according to the degree that the
trigger switch is depressed. Select the speed appropriate
to the material being worked and/or the working
conditions. To achieve continuous operation, pull the
trigger switch all the way back and depress the stopper.
Then, turn the speed adjustment knob to adjust the
blade operating speed as desired (Fig. 4).
NOTE
The speed adjustment knob rotates approximately 3
turns. To turn the switch OFF, pull the trigger switch
again to disengage the stopper, and release the trigger
switch.
CUTTING
CAUTION
⅜ While sawing, the base must be firmly in contact with
the material surface, and the blade must be held at a
right angle. If the base becomes separated from the
material, it could cause the blade to break.
⅜ When cutting while holding the front surface, be
careful of the moving blade and hold the upper part
firmly.
1. Rectilinear cutting
(1) To ensure accurate rectilinear cutting, employ the
optional accessory guide as shown in Fig. 5.
(2) Use the splinter guard to reduce roughness of the
cutting surface of wooden materials. Attach the
splinter guard by inserting it from the front section of
the base until it clicks into place. (Fig. 6)
CAUTION
Set the base in the front position when using the
splinter guard.
2. Cutting a circle or a circular arc
To ensure efficient cutting, employ the optional
accessory guide and nail or wood screw as shown in
Fig. 7. When mounting the guide, loosen the base
bottom screw, and shift the base as far forward as it
will go.
3. Sawing curved lines
When sawing a small circular arc, reduce the feeding
speed of the machine. If the machine is fed too fast, it
could cause the blade to break.
4. Cutting metallic materials
Always use an appropriate cutting agent (spindle oil,
soapy water, etc.). When a liquid cutting agent is not
available, apply grease to the back surface of the
material to be cut.
5. Pocket cutting
(1) In lumber:
Aligning the blade direction with the grain of the
wood, cut step by step until a window hole is cut in
the center of the lumber. (Fig. 8)
(2) In other materials:
When cutting a window hole in materials other than
lumber, initially bore a hole with a drill or similar tool
from which to start cutting.
6. Angular cutting
Set the chip cover to the first step. (Fig. 2)
To adjust the angle of inclination; loosen the base
bottom screw, shift the base position to the side
groove of the semicircular portion, align the scale on
the base semicircular portion (figures engraved on
the scale indicate the angle of inclination) with the
housing edge line, and thoroughly tighten the base
bottom screw (Fig. 9 and 10).
CAUTION
Set the screw to the opposite side of the inclining
side when using the guide (Fig. 11).
SELECTION OF BLADES
1. Accessory blades
To ensure maximum operating efficiency and results
it is very important to select the appropriate blade
best suited to the type and thickness of the material
to be cut. One type of blade is provided as standard
accessory. The blade number is engraved in the
vicinity of the mounting portion of each blade. Select
appropriate blades by referring to Table 1.
MAINTENANCE AND INSPECTION
1. Inspecting the blade
Continued use of a dull or damaged blade will result
in reduced cutting efficiency and may cause
overloading of the motor. Replace the blade with a
new one as soon as excessive abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
4. Servicing
Consult an authorized Service Center in the event of
power tool failure.
