FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting bit protrusion (Fig. 1)
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. 2)
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) posi-
tion. To stop the tool, move the switch lever to the
O (OFF) position.
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
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 (Fig. 6, 7 & 8)
The templet guide provides a sleeve through which the
bit passes, allowing use of the trimmer with templet pat-
terns.
Remove the chip deflector.
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.
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.
NOTE:
• The workpiece will be cut a slightly different size from
the templet. Allow for the distance (X) between the
router bit and the outside of the templet guide. The dis-
tance (X) can be calculated by using the following
equation:
Distance (X) = (outside diameter of the templet guide –
router bit diameter) / 2
Straight guide (Accessory)
The straight guide is effectively used for straight cuts
when chamfering or grooving. (Fig. 9)
Attach the guide plate to the straight guide with the bolt,
the wave washer, the flat washer and the wing nut.
(Fig. 10)
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. 11)
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. 12)
Circular work
Circular work may be accomplished if you assemble the
straight guide and guide plate as shown in Fig. 13 or 14.
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
For cutting circles between 70 mm and 121 mm in radius.
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.
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.
