in reverse.

OPERATION

CAUTION:
Always hold the tool firmly with
one hand on housing. Do not touch the metal part.
1. Set the base on the workpiece to be cut without
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 base flush and advancing smoothly until
the cutting is complete.
► Fig.9
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,
make a sample cut on a piece of scrap lumber to
consider the appropriate feed speed.
You can also confirm the trimmer bit setting by mea-
suring the sample cut.
Templet guide
The templet guide provides a sleeve through which the
trimmer bit passes, allowing use of the trimmer with
templet patterns.

Loosen the clamping screw and then remove the
guide holder and the chip deflector.

2. Loosen the screws and remove the base
protector.

3.
Place the templet guide on the base, and place
the base protector again. Then secure the base protec-
tor 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.

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
The straight guide is effectively used for straight cuts
when chamfering.
► Fig.16
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.
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.
► Fig.19
1.
Attach the chip deflector on the groove of the
base.
2. Install the trimmer guide and guide holder on the
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.
