To start the tool, move the switch lever to the I (ON)
position. To stop the tool, move the switch lever to the O
(OFF) position.
For tool with lock-off button (Fig. 6)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
• Make sure that the shaft lock is released before the
switch is turned on.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, push in the lock-off button and pull the
switch trigger. Release the switch trigger to stop.
Speed adjusting dial
For model 3612C only (Fig. 7)
The tool speed can be changed by turning the speed
adjusting dial to a given number setting from 1 to 5.
Higher speed is obtained when the dial is turned in the
direction of number 5. And lower speed is obtained when
it is turned in the direction of number 1.
This allows the ideal speed to be selected for optimum
material processing, i.e. the speed can be correctly
adjusted to suit the material and bit diameter.
Refer to the table for the relationship between the number
settings on the dial and the approximate tool speed.

CAUTION:
• If the tool is operated continuously at low speeds for a
long time, the motor will get overloaded, resulting in
tool malfunction.
• The speed adjusting dial can be turned only as far as 5
and back to 1. Do not force it past 5 or 1, or the speed
adjusting function may no longer work.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing the bit (Fig. 8)
CAUTION:
• Install the bit securely. Always use only the wrench
provided with the tool. A loose or overtightened bit can
be dangerous.
• Use always a collet which is suitable for the shank
diameter of the bit.
• Do not tighten the collet nut without inserting a bit or
install small shank bits without using a collet sleeve.
Either can lead to breakage of the collet cone.

• Use only router bits of which the maximum speed, as
Insert the bit all the way into the collet cone. Press the
shaft lock to keep the shaft stationary and use the wrench
to tighten the collet nut securely. When using router bits
with smaller shank diameter, first insert the appropriate
collet sleeve into the collet cone, then install the bit as
described above.
To remove the bit, follow the installation procedure in
reverse.
OPERATION

Set the tool base on the workpiece to be cut without the
bit making any contact. Then turn the tool on and wait until
the bit attains full speed. Lower the tool body and move
the tool forward over the workpiece surface, keeping the
tool base flush and advancing smoothly until the cutting is
complete.
When doing edge cutting, the workpiece surface should
be on the left side of the bit in the feed direction. (Fig. 10)

Straight guide (optional accessory)
(Fig. 12)
The straight guide is effectively used for straight cuts
when chamfering or grooving.
Install the straight guide on the guide holder with the wing
bolt (B). Insert the guide holder into the holes in the tool
base and tighten the wing bolt (A). To adjust the distance
between the bit and the straight guide, loosen the wing
bolt (B) and turn the fine adjusting screw (1.5 mm per
turn). At the desired distance, tighten the wing bolt (B) to
secure the straight guide in place. (Fig. 13)
Wider straight guide of desired dimensions may be made
by using the convenient holes in the guide to bolt on extra
pieces of wood.
When using a large diameter bit, attach pieces of wood to
the straight guide which have a thickness of more than 15
mm to prevent the bit from striking the straight guide.

quality of cut, or damage to the 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.
sure to install it on the right side in the feed direction.
This will help to keep it flush with the side of the
workpiece. (Fig. 11)
