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.

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, 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.
