tion. To stop the tool, move the switch lever to the
O (OFF) position.
Electronic function
For model 3707FC only
The tool 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
Soft-start feature minimizes start-up shock, and makes
the tool start smoothly.
Lighting up the lamps
For model 3707F/3707FC only
CAUTION:
• Do not look in the light or see the source of light
directly.
To turn on the lamp, start the tool. Then, the lamp lights

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing trimmer bit (Fig. 3)
CAUTION:
• Do not tighten the collet nut without inserting a bit, or
the collet cone will break.
• Use only the wrenches provided with the tool.
Insert the bit all the way into the collet cone and tighten
the collet nut securely with the two wrenches.
To remove the bit, follow the installation procedure in
reverse.
OPERATION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before removing or installing the trimmer
base.
• Adjust the lever tightening strength of the trimmer
base using its nut to obtain a suitable tightening
strength for your tool. After adjusting, make sure
the trimmer base is secured to the tool. Dislocation
of the trimmer base may cause personal injuries.
Set the tool base on the workpiece to be cut without the
bit making any contact. Then turn the tool on and wait
until the bit attains full speed. Move the tool forward over
the workpiece surface, keeping the tool base flush and
advancing smoothly until the cutting is complete.
When doing edge cutting, the workpiece surface should
be on the left side of the bit in the feed direction. (Fig. 4)
NOTE:
• Moving the tool forward too fast may cause a poor qual-
ity of cut, or damage to the bit or motor. Moving the tool
forward too slowly may burn and mar the cut. The
proper feed rate will depend on the bit size, the kind of
workpiece and depth of cut. Before beginning the cut
on the actual workpiece, it is advisable to make a sam-
ple cut on a piece of scrap lumber. This will show
exactly how the cut will look as well as enable you to
check dimensions.
• When using the trimmer shoe, the straight guide or the
trimmer guide, be sure to keep it on the right side in the
feed direction. This will help to keep it flush with the
side of the workpiece. (Fig. 5)
CAUTION:
• Since excessive cutting may cause overload of the
motor or difficulty in controlling the tool, the depth of cut
should not be more than 3 mm at a pass when cutting
grooves. When you wish to cut grooves more than
3 mm deep, make several passes with progressively
deeper bit settings.
Templet guide
The templet guide provides a sleeve through which the
bit passes, allowing use of the trimmer with templet pat-
terns. (Fig. 6)
Loosen the screws and remove the base protector. Place
the templet guide on the base and replace the base pro-
tector. Then secure the base protector by tightening the
screws. (Fig. 7)
Secure the templet to the workpiece. Place the tool on
the templet and move the tool with the templet guide slid-
ing along the side of the templet. (Fig. 8)
