Installing or removingtrimmer bit
CAUTION :
Always be sure that the tool is switched off and unplugged before installing or removing
the bit.
Insert the bit all the way into the collet
cone and tighten the collet nur securely
with the
two wrenches.
To remove the bit, follow the installation
procedure in reverse.
CAUTION
:
0 Do nottighten the collet nut without inserting a bit, or the collet cone will break.
0 Use only the wrenches providedwith the tool.
Adjustingbit protrusion
To adjust the bitprotrusion, loosen the nut
and move the tool
base up or down as de-
sired by turning the adjusting screw. After
adjusting, tighten the nut firmly to secure
the tool base.
Switch action
To start the tool, move the switch lever
to the "ON" position. To stop, move the
switch lever tothe
"OFF" position.
5

Operation
.Set the tool base on the workpiece to be cut without the bit makingany contact. Then
turn the tool on and wait until the bitattainsfull speed. Move the tool forward over the
workpiece surface, keepingthe tool base flush and advancing smoothly until the cutting
is complete.
0 When doing edge cutting, the workpiece surface should be on the left side of the bit in
the feed direction.
(See the figure below)

I
Correct bit feed direction
NOTE :
0 Moving the tool forward too fast may cause a poor quality of cut, or damage tothe 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.
0 When using the trimmer shoe, the straightguide or the trimmer guide, be sure tokeep it
on the rightside 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 bitsettings.

Straight guide (Optional accessory)
The straight guide is effectively used for
straight cuts when chamfering or grooving.
Attach the guide plate tothe straight guide
with the bolt, the wave washer, the flat
washer and the wing nut.
Remove the chip deflector. Attach the
straight guide with the clamp screw (A).
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 securely.

When cutting, movethe tool with the straight guide flush with the side of the workpiece.
If the distance
(A) between the side of the
workpiece and the cutting position
is too
wide for the straight guide, or ifthe side of
the workpiece
is not straight, the straight
guide cannot be used. In this case, firmly
clamp
a straight board to the workpiece
and use
it as a guide against the trimmer
base. Feed the tool in the direction of the
arrow.

Align the center hole in the straight guide
with the center of the circle to be cut.
Drive
a nail less than 6 mm (1/4") in
diameter into the center hole to secure the
straight guide. Pivot the tool around the
nail in clockwise direction.

Trimmer guide
Trimming, curved cuts in veneers for fur-
niture and the like can be done easilywith
the trimmer guide. The guide roller rides
the curve and assures
a fine cut.
Install the trimmer guide on the tool base
with the clamp screw (A). Loosen the
clamp screw
(B) and adjust the distance
between the bit and the trimmer guide by
turning the adjusting screw
(1 mm or about
3/64" per turn). At the desired distance,
tighten the clamp screw
(B) to secure the
trimmer guide inplace.
When cutting, move the tool with the guide
roller ridingthe side of the workpiece.

Templet guide
The templet guideprovides a sleeve through
which the bit passes, allowing use of the
trimmer with templet patterns.
Remove the chip deflector. Loosen the
screws and remove the base protector.
Place the templet guide on the base and re-
place the base protector. Then secure the
base protector by tightening the screws.
Secure the templet tothe workpiece. Place
the tool on
the templet and movethe tool
with the templet guide sliding along the
side of the templet.
