ADDITIONAL SAFETY RULES ENB033-2
1. Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact with a “live”wire will make exposed metal parts
of the tool “live”and shock the operator.
2. Wear hearing protection during extended period
of operation.
3. Handle the bits very carefully.
4. Check the bit carefully for cracks or damage
before operation. Replace cracked or damaged
bit immediately.
5. Avoid cutting nails. Inspect for and remove all
nails from the workpiece before operation.
6. Hold the tool firmly with both hands.
7. Keep hands away from rotating parts.
8. Make sure the bit is not contacting the work-
piece before the switch is turned on.
9. Before using the tool on an actual workpiece, let
it run for a while. Watch for vibration or wob-
bling that could indicate improperly installed bit.
10. Be careful of the bit rotating direction and the
feed direction.
11. Do not leave the tool running. Operate the tool
only when hand-held.
12. Always switch off and wait for the bit to come to
a complete stop before removing the tool from
workpiece.
13. Do not touch the bit immediately after operation;
it may be extremely hot and could burn your
skin.
14. Always lead the power supply cord away from
the tool towards the rear.
15. Do not smear the tool base carelessly with thin-
ner, gasoline, oil or the like. They may cause
cracks in the tool base.
16. Draw attention to the need to use cutters of the
correct shank diameter and which are suitable
for the speed of the tool.

FUNCTIONAL
DESCRIPTION CAUTION:
•Always be sure that the tool is switched off and unplugged before
adjusting or checking function on the tool.
Adjusting the depth of cut
Place the tool on a flat surface. Loosen the screw securing the stopper pole.
Loosen the lock lever and lower the tool body until the bit just touches the flat
surface. Tighten the lock lever to lock the tool body.
Next, lower the stopper pole until it makes contact with the adjusting hex bolt.
Align the depth pointer with the “0”graduation.
Raise the stopper pole until the desired depth of cut is obtained. The depth of
cut is indicated on the scale (1 mm per graduation) by the depth pointer. Then
tighten the screw to secure the stopper pole.
Now, your predetermined depth of cut can be obtained by loosening the lock
lever and then lowering the tool body until the stopper pole makes contact with
the adjusting hex bolt.
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 15 mm at a
pass when cutting grooves with an 8 mm diameter bit.
•When cutting grooves with a 20 mm diameter bit, the depth of cut should
not be more than 5 mm at a pass.
When you wish to cut grooves more than 15 mm deep with an 8 mm
diameter bit or more than 5 mm deep with a 20 mm diameter bit, make
several passes with progressively deeper bit settings.

Stopper block
The stopper block has three adjusting hex bolts which raise or lower 0.8 mm
per turn. You can easily obtain three different depths of cut using these adjust-
ing hex bolts without readjusting the stopper pole.
Adjust the lowest hex bolt to obtain the deepest depth of cut, following the
method of “Adjusting depth of cut”. Adjust the two remaining hex bolts to
obtain shallower depths of cut. The differences in height of these hex bolts are
equal to the differences in depths of cut.
To adjust the hex bolts, first loosen the hex nuts on the hex bolts with the
wrench and then turn the hex bolts. After obtaining the desired position,
tighten the hex nuts while holding the hex bolts in that desired position. The
stopper block is also convenient for making three passes with progressively
deeper bit settings when cutting deep grooves.
CAUTION:
When using a bit having total length of 60 mm or more, or edge length of 35
mm or more, the depth of cut cannot be adjusted as previously mentioned. To
adjust, proceed as follows:
Loosen the lock lever and carefully adjust bit protrusion below the tool base to
the desired depth of cut by moving the tool body up or down. Then retighten
the lock lever to lock the tool body at that depth of cut. Keep the tool body
locked at this position during use. Since the bit always protrudes from the tool
base, be careful when handling the tool.
Adjusting the lock lever
The locked position of the lock lever is adjustable. To adjust it, loosen the lock
lever 3/4 turn and press the center of the lock lever. The hex nut will come out.
Set the hex nut to the desired position and tighten the lock lever.
Switch action
CAUTION:
•Before plugging in the tool, always check to see that the switch trigger
actuates properly and returns to the “OFF”position when released.
To start the tool, simply pull the switch trigger. Release the switch trigger to
stop.

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
CAUTION:
•Install the bit securely. Always use only the wrenches provided with the
tool. A loose or overtightened bit can be dangerous.
•Do not tighten the collet nut without inserting a bit. It can lead to
breakage of the collet cone.
Insert the bit all the way into the collet cone and tighten the collet nut securely
with the two wrenches.
A 6 mm or 1/4”collet cone is also provided as standard equipment besides the
8 mm or 3/8”collet cone that is factory installed on the tool. Use the correct
size collet cone for the bit which you intend to use.
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 con-
tact. 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.
NOTE:
•Moving the tool forward too fast may cause a poor 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.
•When using the straight guide, be 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.

Straight guide
The straight guide is effectively used for straight cuts when chamfering or
grooving.
To install the straight guide, insert the guide bars into the holes in the tool
base. Adjust the distance between the bit and the straight guide. At the desired
distance, tighten the wing bolts to secure the straight guide in place.
When cutting, move the 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 if the 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 router base. Feed the tool in the
direction of the arrow.
Templet guide (Accessory)
The templet guide provides a sleeve through which the bit passes, allowing
use of the tool with templet patterns.
To install the templet guide, loosen the screws on the tool base, insert the tem-
plet guide and then tighten the screws.

Secure the templet to the workpiece. Place the tool on the templet and move
the tool with the templet guide sliding along the side of the templet.
NOTE:
•The workpiece will be cut a slightly different size from the templet. Allow
for the distance (X) between the bit and the outside of the templet guide.
The distance (X) can be calculated by using the following equation:
Distance (X) = (outside diameter of the templet guide - bit diameter) / 2
Vacuum head set (Accessory)
Use the vacuum head for dust extraction. Install the vacuum head on the tool
base using the two screws.
