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
► Fig.1: 1. Stopper pole 2. Screw
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.
► Fig.2: 1. Lock lever 2. Screw
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.

4. Adjusting hex bolt 5. Stopper block
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 diame-
ter 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
► Fig.4: 1. Depth pointer 2. Screw 3. Stopper pole
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.
