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, 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 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
009745
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.
