OPERATING INSTRUCTIONS
Installing or removing trimmer bit (Fig. 1)
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the bit.
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.
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.
Installing trimmer shoe
(after it has been removed from the tool)
NOTE:
The trimmer shoe is factory installed on the tool.
Use the bolts, wing nuts, spring washers and flat
washers to install the trimmer shoe as shown in Fig. 2.
Adjusting bit protrusion (Fig. 3)
To adjust the bit protrusion, loosen the lever and
move the tool base up or down as desired by press-
ing and turning the adjusting roller. After adjusting,
tighten the lever firmly to secure the tool base.
Adjusting angle of tool base (Fig. 4)
Loosen the wing bolts and adjust the angle of the tool
base (5° per graduation) to obtain the desired cutting
angle.
Adjusting amount of chamfering
To adjust the amount of chamfering, loosen the wing
nuts and adjust the trimmer shoe.
CAUTION:
With the tool unplugged and switch in the "OFF" posi-
tion, rotate the collet nut on the tool several times to
be sure that the bit turns freely and does not contact
the base or trimmer shoe in any way.
Switch action (Fig. 5)
CAUTION:
Before plugging in the tool, always be sure that the
tool is switched off.
To start the tool, move the switch lever to the "I" (ON)
position. To stop the tool, move the switch lever to the
"0" (OFF) position.
The tool equipped with electronic function is easy to
operate because of the following features.
Constant speed control
For 3708FC only
Electronic speed control for obtaining constant
speed. Possible to get fine finish, because the rotat-
ing speed is kept constant even under load condition.
Soft start
For 3708FC only
Soft-start feature minimizes start-up shock, and makes
the tool start smoothly.
Lighting up the lamps
For 3708F/3708FC only
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
• Do not look in the light or see the source of light
(Fig. 2)
directly.
To turn on the lamp, start the tool. Then the lamp
lights up the top of the bit. To turn it off, stop the tool.
NOTE:
Use a dry cloth to wipe the dirt off the lens of lamp.
Be careful not to scratch the lens of lmap, or it may
lower the illumination.
Operation (Fig. 6, 7 & 8)
Turn the tool on without the bit making any contact
with the workpiece and wait until the bit attains full
speed. Then move the tool over the workpiece sur-
face, keeping the tool base and trimmer shoe flush
with the sides of the workpiece.
(Note)
This tool can be used as a conventional trimmer
when you remove the trimmer shoe.
When doing edge cutting, the workpiece surface
should be on the left side of the bit in the feed direction.
NOTE:
• Moving the tool forward too fast may cause a poor
quality 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 sample 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.
