Removing saw blade
CAUTION:
When you remove the saw blade, be careful not to hurt
your fingers with the top of the blade or the tips of work-
piece.
Open the tool opener to the position shown in the figure.
Pull the saw blade out toward the base.
(Fig. 3)
NOTE:
Occasionally lubricate the roller.
Hex wrench storage (Fig. 4)
When not in use, the hex wrench can be conveniently
stored.
Selecting the cutting action (Fig. 5)
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.
Switch action (Fig. 6)
CAUTION:
Before plugging in the tool, always check to see that the
tool is switched off.
To start the tool, slide the switch lever to the “I” position.
To stop the tool, slide the switch lever to the “O” position.
Speed adjusting dial (Fig. 7)
For 4341CT, 4341FCT only
The tool speed can be infinitely adjusted between 800
and 2,800 strokes per minute by turning the adjusting
dial. Higher speed is obtained when the dial is turned in
the direction of number 5; 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.
CAUTION:
The speed adjusting dial can be turned only as far as 5
and back to 1. Do not force it past 5 or 1, or the speed
adjusting function may no longer work.
For 4341CT, 4341FCT only
The tools equipped with electronic function are easy to
operate because of the following features.
Constant speed control
Electronic speed control for obtaining constant speed.
Possible to get fine finish, because the rotating speed is
kept constant even under load condition.
Soft start feature
Safety and soft start because of suppressed starting
shock.
Lighting up the lamps (For 4341FCT only)
CAUTION:
Do not look in the light or see the source of light directly.
To turn on the lamp, pull the trigger. Release the trigger
to turn it off.
NOTE:
Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower the
illumination.
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.
