CAUTION:
Do not tighten the collet nut without inserting a bit,
•
or the collet cone will break.
Use only the wrenches provided with the tool.
•
Insert the bit all the way into the collet cone and tighten
the collet nut securely with the two wrenches. To remove
the bit, follow the installation procedure in reverse.
OPERATION
Set the tool base on the workpiece to be cut without the
bit making any contact. Then turn the tool on and wait
until the bit attains full speed. Move the tool forward over
the workpiece surface, keeping the tool base flush and
advancing smoothly until the cutting is complete.
When doing edge cutting, the workpiece surface should
be on the left side of the bit in the feed direction.

NOTE:
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 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.

NOTE:
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.
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 (1/8") at a
pass when cutting grooves. When you wish to cut
grooves more than 3 mm (1/8") deep, make
several passes with progressively deeper bit
settings.
Templet guide
006616
The templet guide provides a sleeve through which the
bit passes, allowing use of the trimmer with templet
patterns.
Remove the chip deflector.
