Stopper block

4. Adjusting hex bolt 5. 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 adjusting 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, turn the hex bolts. 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 protru-
sion 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: 1. Lock lever 2. Screw
The locked position of the lock lever is adjustable. To
adjust it, remove the screw securing the lock lever. The
lock lever will come off. Set the lock lever at the desired
angle. After adjustment, tighten the lock lever clockwise.
Switch action
► Fig.6: 1. Switch trigger
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.
Use the correct size collet cone for the bit which you
intend to use.
To remove the bit, follow the installation procedure in
reverse.
Changing the collet cone
► Fig.8: 1. Collet nut 2. Collet cone
CAUTION:
• Use the correct size collet cone for the bit that
you are going to use.
• Do not tighten the collet nut without installing a
bit, or the collet cone may break.
To change the collet cone, loosen the collet nut and
remove. Replace the installed collet cone with desired
collet cone. Reinstall collet nut.

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.

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.
