INSTALLING AND REM OVING BITS

WARNING

Be sure to sw itch pow er OFF and disconnect the
plug from  the receptacle to avoid serious trouble.

1. Installing bits
(1) Clean and insert shank of bit into the collet chuck

until shank bottom s, then back it out approxim ately
2 m m .

(2) With the bit inserted and pressing the lock pin

holding the arm ature shaft, use the 23 m m  w rench
to firm ly tighten the collet chunk in a clockw ise
direction (view ed from  under the router). (Fig. 1)

CAUTION

✁

Ensure that the collet chuck is firm ly tightened after
inserting a bit. Failure to do so w ill result in dam age
to the collet chuck.

✁

Ensure that the lock pin is not inserted into the
arm ature shaft after tightening the collet chuck.
Failure to do so w ill result in dam age to the collet
chuck, lock pin and arm ature shaft.

(3) Be sure to use a chuck sleeve w hen using a 6 m m

bit w ith a collet chuck capacity of 8 m m . First insert
the chuck sleeve deeply in the collet chuck, then
insert the bit in the chuck sleeve. Tighten the collet
chuck firm ly as in step (1) and (2).

2. Removing Bits

When rem oving the bits, do so by follow ing the
steps for installing bits in reverse order.

CAUTION

Ensure that the lock pin is not inserted into the
arm ature shaft after tightening the collet chuck.
Failure to do so w ill result in dam age to the collet
chuck, lock pin and arm ature shaft.

HOW TO USE THE ROUTER

1. Adjusting depth of cut (Fig. 2)
(1) Use stopper pole to adjust depth of cut.

✶

Place the tool on a flat w ood surface.

✷

Turn the stopper block so that section to w hich the
cutting depth setting screw  on a stopper block is
not attached com es to the bottom  of the stopper
pole. Loosen pole lock knob allow ing the stopper
pole to contact w ith stopper block.

✸

Loosen the lock lever and press the tool body until
the bit just touches the flat surface. Tighten the lock
lever at this point. (Fig. 3)

✹

Tighten pole lock knob. Align the depth indicator
w ith the “ 0”  graduation of scale.

✺

Loosen pole lock knob, and raise until indicator
aligns w ith the graduation representing the desired
cutting depth. Tighten pole lock knob.

✻

Loosen the lock lever and press the tool body dow n
until the stopper block to obtain the desired cutting
depth.

(2) As show n in Fig. 4 (a), loosening the tw o nuts on

the threaded colum n and m oving then dow n w ill
allow  you to m ove dow n to the end position of the
bit w hen the lock lever is loosened. This is helpful
w hen m oving the router to align the bit w ith the
cutting position.
As show n in Fig. 4 (b), tighten the upper and low er
nuts to secure the cutting depth.

(3) When you are not using the scale to set the cutting

depth, push up the stopper pole so that it is not
in the w ay.

2. Stopper block (Fig. 5)

The 2 cut-depth setting screw s attached to the
stopper block can be adjusted to sim ultaneously set
3 different cutting depth. Use a w rench to tighten
the nuts so that the cut-depth setting screw s do not
com e loose at this tim e.

3. Guiding the router
WARNING

Be sure to sw itch pow er OFF and disconnect the
plug from  the receptacle to avoid serious trouble.

(1) Tem plate Guide

Use the tem plate guide w hen em ploying a tem plate
for producing a large quantity of identifically shaped
products.
As show n in Fig. 6, secure the tem plate guide to
the base of the router w ith tw o accessory screw s.
At this tim e, ensure that the projection side of the
tem plate guide is facing the bottom  surface of the
base of the router.
A tem plate is a profiling m old m ade of plyw ood
or thin lum ber.
When m aking a tem plate, pay particular attention
to the m atters described bellow  and illustrated in
Fig. 7.
When using the router along the interior plane of
the tem plate, the dim ensions of the finished product
w ill be less than the dim ensions of the tem plate
by an am ount equal to dim ension “ A” , the difference
betw een the radius of the tem plate guide and the
radius of the bit. The reverse is true w hen using
the router along the exterior of the tem plate.
Secure the tem plate to the w orkpiece. Feed the
router in the m anner that the tem plate guide m oves
along the tem plate as show n in Fig. 8.

(2) Straight guide (Fig. 9)

Use straight guide for cham fering and groove cutting
along the m aterials side.

✶

Insert the guide bar into the hole in the bar holder,
then lightly tighten the 2 w ing bolts (A) on top of
the bar holder.

✷

Insert the guide bar into the hole in the base, then
firm ly tighten the w ing bolt (A).

✸

M ake m inute adjustm ents of the dim ensions betw een
the bit and the guide surface w ith the feed screw ,
then firm ly tighten the 2 w ing bolts (A) on top of
the bar holder and the w ing bolt (B) that secures
the straight guide.

✹

As show n in Fig. 10, securely attach the bottom  of
the base to processed surface of the m aterials. Feed
the router w hile keeping the guide plane on the
surface of the m aterials.

4. Adjusting the rotation speed (M odel M 8V2 only)

The M 8V2 has an electronic control system  that
allow s stepless rpm  changes.
As show n in Fig. 11, dial position “ 1”  is for m inim um
speed, and position “ 6”  for m axim um  speed.

5. Cutting
CAUTION

✁

Wear eye protection w hen operating this tool.

✁

Keep your hands, face and other body parts aw ay
from  the bits and any other rotating parts, w hile
operating the tool.
