3.
Place the templet guide on the base and replace
the base protector. Then secure the base protector by
tightening the screws.
4. 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.

4. Workpiece 5. Templet guide
NOTE: The workpiece will be cut a slightly different
size from the templet. Allow for the distance (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 the templet
guide - trimmer bit diameter) / 2
Straight guide
Optional accessory
The straight guide is effectively used for straight cuts
when chamfering or grooving.
► Fig.11
1. Attach the guide plate to the straight guide with
the bolt and the wing nut.

2. Remove the guide holder and the chip deflector
then attach the straight guide with the clamping screw.

nut 4. Base
3.
Loosen the wing nut on the straight guide and
adjust the distance between the trimmer bit and the
straight guide. At the desired distance, tighten the wing
nut securely.
4. 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.

Circular work
Circular work may be accomplished if you assemble the
straight guide and guide plate. Minimum and maximum
radius of circles to be cut (distance between the center
of circle and the center of trimmer bit) are as follows:
• Mininum : 70 mm
• Maximum : 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.
1.
Align the center hole in the straight guide with the
center of the circle to be cut.
2. Drive a nail less than 6 mm in diameter into the
center hole to secure the straight guide.
3. Pivot the tool around the nail in clockwise
direction.

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.

1.
Attach the chip deflector on the groove of the
base.
2. Install the trimmer guide and guide holder on the
tool base with the clamping screw (A).
3. Loosen the clamping screw (B) and adjust the
distance between the trimmer bit and the trimmer guide
by turning the adjusting screw (1 mm per turn). At the
desired distance, tighten the clamping screw (B) to
secure the trimmer guide in place.

MAINTENANCE
CAUTION:
Always be sure that the tool is
switched off and unplugged before attempting to
perform inspection or maintenance.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
Replacing carbon brushes
► Fig.21: 1. Limit mark
Check the carbon brushes regularly.
Replace them when they wear down to the limit mark.
Keep the carbon brushes clean and free to slip in the
