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.41
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.

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.

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.
►

4.
Move the tool with the straight guide flush with the
side of the workpiece.
►
Fig.46
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.47
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.
