NOTICE:
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.
Using the straight guide
Optional accessory
1. Assemble the straight guide with the bolt and the
wing nut.
► Fig.41: 1. Bolt 2. Wing nut
2.
Attach the straight guide to the trimmer base with
the clamp screw.
► Fig.42: 1. Clamp screw
3. 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.
► Fig.43: 1. Wing nut
4.
Move the tool with the straight guide flush with the
side of the workpiece.
► Fig.44
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 work-
piece and use it as a guide against the trimmer base.
Feed the tool in the direction of the arrow.
► Fig.45
Using the straight guide for circular
work
For circular work, assemble the straight guide as shown
in the figures. The minimum and maximum radius of
circles to be cut (distance between the center of circle
and the center of bit) are as follows:
• Minimum: 70 mm
• Maximum: 221 mm
For cutting circles between 70 mm and 121 mm in
radius. ► Fig.46: 1. Center hole
For cutting circles between 121 mm and 221 mm in
radius.
► Fig.47: 1. Center hole
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 cen-
ter 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 the clockwise
direction.

Using the templet guide
Optional accessory
The templet guide allows for repetitive cut with templet
patterns by using a templet.
1. Loosen the screws on the base plate, and then
remove the base plate from the trimmer base.
2. Place the templet guide on the base, and then
attach the base plate by tightening the screws.
► Fig.49: 1. Base plate 2. Templet guide
3. Place the tool on the templet and move the tool
with the templet guide sliding along the side of the
templet.
► Fig.50
NOTE: The actual cut size on the workpiece is slightly
different from the templet. The difference is the dis-
tance (X) between the trimmer bit and the outside of
the templet guide. The distance (X) can be calculated
by using the following equation:
Distance (X) = (outside diameter of templet guide - trimmer bit diameter) / 2

(X) 4. Outside diameter of templet guide
Using the trimmer guide
Optional accessory
The trimmer guide allows for trimming the curved side
like veneers for furniture by moving the guide roller
along the side of the workpiece.
► Fig.52
1.
Loosen the clamp screw, then install the trimmer guide
on the trimmer base, and then tighten the clamp screw.
► Fig.53: 1. Clamp screw
2. Loosen the clamp screw and adjust the distance
between the trimmer bit and the trimmer guide by turning
the adjusting screw (1 mm per turn). At the desired dis-
tance, tighten the clamp screw to secure the trimmer guide.

3. Move the tool with the guide roller riding the side
of the workpiece.

Using the tool with the tilt base
The tilt base is convenient for chamfering. Loosen the
wing screws, then tilt the tool at the desired angle, and
then tighten the wing screws.
Firmly clamp a straight board to the workpiece and use
it as a guide against the tilt base. Feed the tool in the
direction of the arrow. ► Fig.56: 1. Wing screw
Using the tilt base plate with the
trimmer base
To use the trimmer base with a square base plate,
remove the base plate from the tilt base, and then
attach it to the trimmer base.
