OPERATION
When using the trimmer shoe, the straight guide, the trimmer 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 work piece.
CAUTION:
Since excessive cutting may cause overload of the motor, or difficulty in controlling
the tool, the depth of the 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.
Straight Guide
The straight guide is effectively used for straight-line cuts when chamfering or
grooving.
Attach the guide plate to the straight guide with the bolt, flat washer, wave washer,
and wing nut.
Remove the chip deflector. Attach the straight guide with the clamp screw. 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, move the tool with the straight guide flush with the side of the work
piece.
If the distance 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 down 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.
Circular Cutting
Circular cutting may be accomplished if you assemble the straight guide and guide
plate.
Minimum and Maximum radius of circles to be cut (distance between the center of
circle and the center of the bit) are as follows:
Minimum: 70 mm (2-3/4")
Maximum: 221 mm (8-1/16")
Note: Circles between 172 mm (6-3/4") and 186 mm (7-5/16") in radius cannot be
cut using this guide.
For cutting circles between 70 mm (2-3/4") and 121 mm (4-3/4") in radius
For cutting circles between 121 mm (4-3/4") and 221 mm (8-11/16") in radius
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 of the hole to secure the
straight guide. Pivot the tool around the nail in a clockwise direction.
Trimmer Guide
Trimming curved cuts into veneers for furniture and other projects can be done
easily with the trimmer guide. The guide roller rides the curve and assures a fine cut.
