OPERATION
CAUTION:
Always hold the tool firmly with one
hand on housing. Do not touch the metal part.
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.
1. Set the tool base on the workpiece to be cut with-
out the trimmer bit making any contact.
2.
Turn the tool on and wait until the trimmer bit
attains full speed.
3. Move the tool forward over the workpiece surface,
keeping the tool base flush and advancing smoothly
until the cutting is complete.
► Fig.4
When doing edge cutting, the workpiece surface
should be on the left side of the trimmer bit in the feed
direction.

3. View from the top of the tool 4. Feed
direction
When using the straight guide or the trimmer guide,
be sure to keep it on the right side in the feed direc-
tion. This will help to keep it flush with the side of the
workpiece.

NOTE: Moving the tool forward too fast may cause
a poor quality of cut, or damage to the trimmer 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 sample cut on a piece of scrap
lumber. This will show exactly how the cut will look as
well as enable you to check dimensions.
Templet guide
The templet guide provides a sleeve through which the
trimmer bit passes, allowing use of the trimmer with
templet patterns.
