For example, if a cutting depth of 10mm is desired
and the "cut 0" reading is as shown in Fig. 5
(a), raise the stopper pole arrow to the position
shown in Fig. 5 (b).
(2) With the scale set as described above, loosen the
knob ass'y and push downward on the handles until
the scale contacts the base.
The router is now adjusted to the desired cutting
depth.
(3) It is possible to decrease the clearance between the
bit tip and the material by loosening and moving
downward the nut on the screw.
This step provides convenience when moving the
router to align the bit with the cutting place.
(4) When adjusting the cutting depth without using the
scale, force the scale upward to prevent it from
getting in the way.
2. Guiding the Router
There are several ways of guiding the router. Select
the method most convenient for your work
requirements.
(1) Parallel Guide Ass'y
Use the parallel guide ass'y for chamfering along
the material side or for grooving.
To properly mount the parallel guide ass'y on the
router, first of all, as shown in Fig. 6, attach the
two wing bolts and the two lock springs to the
screw holes on the top side of the base. Insert the
guide bars in the holes on the base and adjust the
distance from the bit to the guide surface.
Tighten the two wing bolts to secure the parallel
guide ass'y.
Feed the router in a manner that the guide surface
of the parallel guide ass'y moves along the material
side.
An auxiliary wood guide can be mounted on the
parallel guide assembly, as shown in Fig. 7, and
fixed in position by utilizing the holes on the guide
surface.
(2) Template Guide
Use the template guide when employing a template
for producing a large quantity of identically shaped
products.
As shown in Fig. 8, secure the template guide to
the base of the router with two accessory screws.
At this time, ensure that the projection side of the
template guide is facing the bottom surface of the
base of the router.
A template is a profiling mold made of plywood
or thin lumber. When making a template, pay
particular attention to the matters described below
and illustrated in Fig. 9.
When using the router along the interior plane of
the template, the dimensions of the finished product
will be less than the dimensions of the template
by an amount equal to dimension "A", the distance
between the edge of the template and the edge of
the bit. The reverse is true when using the router
along the exterior of the template.
Secure the template to the material. Feed the router
in a manner that the template guide moves along
the template as shown in Fig. 10.
(3) Router Base
Use of the router base as a guide is highly convenient
when working on material with dimensions too
large for use of the parallel guide assembly.
As shown in Fig. 11, secure a straight piece of board
(to be used as a guide) in the appropriate position
on the material, and feed the router in a manner
that the flat side of the router base moves along
the board guide.
Similarly, it is possible to process the material by
guiding the curved side of the router base along
a large dimension template as shown in Fig. 12.
(4) Bits with Pilot
A bit with a pilot is a bit with a rounded shaft with
no cutting edges on its lower portion. Feed the
router by sliding the pilot along the side of the
material as shown in Fig. 13.
3. Cutting
(1) Turn the switch to the ON position while the bit
is separated from the material as shown in Figs.
14 and 15. Do not start cutting operation until the
bit has reached full rotating speed.
(2) The bit rotates clockwise (arrow direction indicated
on the end bracket). To obtain maximum cutting
effectiveness, feed the router in conformance with
the feed directions shown in Fig. 16.
(3) As illustrated in Fig. 17, when the router is feed
in the direction indicated by the black arrow, a
certain force acts on the routher that causes it to
move in the direction indicated by the white arrow.
During operation, be sure to guide the router so
that it does deviate from the desired cutting line.
HOW TO USE THE OPTIONAL ACCESSORIES
1. Feed screw assembly
By using the feed screw assembly, the distance
between the bit and the parallel guide assembly or
trimmer guide assembly can be finely adjusted. As
shown in Fig. 18, attach the feed screw to the
parallel guide assembly or trimmer assembly, and
attach the rod to the base with the provided nuts.
Fine adjustment can be achieved by turning the
feed screw. Pushing the button on the feed screw
will release the grip of the screw and permit fast
movement of the guide assembly.
2. Trimmer guide assembly
Suitable for trimming, beveling or working the inner
surface of furniture or house fittings with plywood
or veneer surfaces. Insert the assembly guide bars
into the holes of the base, adjust the distance
between the bit and roller as desired, and tighten
the wing bolts on the base to fix the trimmer in
position. Then, loosen the wing bolt (A), shown in
Fig. 19, and set the roller to the appropriate position.
Ensure that the wing bolt (A), is firmly retightened
before using the machine, as shown in Fig. 20.
3. Chuck Sleeve
When using the 6mm or 6.35 mm ø bit for a collet
with an inner diameter of 8mm, you need the 8
× 6 or 8 × 6.35 chuck sleeve, respectively.
CAUTION
8 × 6 chuck sleeve is equipped with a groove, while
the 8 × 6.35 is not. Never use a 6mm ø shaft bit
with an 8 × 6.35 chuck sleeve, or a 6.35mm ø shaft
bit with an 8 × 6 chuck sleeve.
