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
Fig.5
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
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.
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
Fig.7
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 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.8
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.
Fig.9
Straight guide
Fig.10
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.
Fig.11
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.
Fig.12
Templet guide (Accessory)
Fig.13
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 templet guide and then tighten the
screws.
