OPERATION
Using the tool with the trimmer base
Set the tool base on the workpiece without the trimmer
bit making any contact. Turn the tool on and wait until
the bit attains full speed. Move the tool forward over
the workpiece surface. Keep the tool base flush while
moving the tool.
When cutting the edge, be sure to keep the workpiece
surface on the left side of the trimmer bit in the feed
direction.

► Fig.39

NOTE: Before cutting on the actual workpiece, it is
recommended to make a sample cut. The proper feed
speed depends on the trimmer bit size, the kind of
workpiece, and depth of cut. 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 cutting surface.
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.

guide
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.

3. Place the tool on the templet and move the tool
with the templet guide sliding along the side of the
templet.
