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.
Adjusting bit protrusion (Fig. 2)
To adjust the bit protrusion, loosen the nut and move the
tool base up or down as desired by turning the adjusting
screw. After adjusting, tighten the nut firmly to secure the
tool base.
Switch action (Fig. 3)
To start the tool, move the switch lever to the "ON" posi-
tion. To stop, move the switch lever to the "OFF" position.
Operation
• 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 set-
tings.
Straight guide
The straight guide is effectively used for straight cuts
when chamfering or grooving. (Fig. 6)
Attach the guide plate to the straight guide with the bolt,
the wave washer, the flat washer and the wing nut.
(Fig. 7)
Templet guide
The templet guide provides a sleeve through which the bit passes, allowing use of the trimmer with templet patterns.
(Fig. 16)
Remove the chip deflector. Loosen the screws and remove the base protector. Place the templet guide on the base
and replace the base protector. Then secure the base protector by tightening the screws. (Fig. 17)
Secure the templet to the workpiece. Place the tool on the templet and move the tool with the templet guide sliding
along the side of the templet. (Fig. 18)

Remove the chip deflector. Attach the straight guide with
the clamp screw (A). Loosen the wing nut on the straight
guide and adjust the distance between the bit and the
straight guide. At the desired distance, tighten the wing
nut securely. (Fig. 8)
When cutting, move the tool with the straight guide flush
with the side of the workpiece.
If the distance (A) between the side of the workpiece and
the cutting position is too wide for the straight guide, or if
the side of the workpiece is not straight, the straight
guide cannot be used. In this case, firmly clamp a
straight board to the workpiece and use it as a guide
against the trimmer base. Feed the tool in the direction of
the arrow. (Fig. 9)
Circular work
• Circular work may be accomplished if you assemble
the straight guide and guide plate as shown in
Fig. 10 or 11.
Fig. 10 for cutting circles between 70 mm and 121 mm
in radius.
Fig. 11 for cutting circles between 121 mm and
221 mm in radius.
NOTE:
Circles between 172 mm and 186 mm in radius cannot
be cut using this guide.
• Min. and max. radius of circles to be cut (distance
between the center of circle and the center of bit) are
as follows:
Min.: 70 mm
Max.: 221 mm
Align the center hole in the straight guide with the center
of the circle to be cut. Drive a nail less than 6 mm in
diameter into the center hole to secure the straight guide.
Pivot the tool around the nail in clockwise direction.
(Fig. 12)
Trimmer guide
Trimming, curved cuts in veneers for furniture and the like
can be done easily with the trimmer guide. The guide
roller rides the curve and assures a fine cut. (Fig. 13)
Install the trimmer guide on the tool base with the clamp
screw (A). Loosen the clamp screw (B) and adjust the
distance between the bit and the trimmer guide by turn-
ing the adjusting screw (1 mm per turn). At the desired
distance, tighten the clamp screw (B) to secure the trim-
mer guide in place. (Fig. 14)
When cutting, move the tool with the guide roller riding
the side of the workpiece. (Fig. 15)
