By
turning the knob, the upper limit of the
tool body can
be
adjusted. When the tip of
the bit
is
retracted more than required in
relation to the base plate surface, turn the
knob to lower the upper limit.
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 20 mm (25/32")
at
a
pass when cutting
grooves. When you wish to cut grooves more than 20 mm (25/32") deep, make several
passes with progressively deeper bit settings.
.Do
not lower the knob too low. The bit will protrude dangerously.
Stopper
The stopper has three adjusting hex bolts
which raise or lower
0.8
mm (about 1/32")
per turn. You can easily obtain three dif-
ferent 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 dif-
ferences 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 hold-
ing 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.
Switch
action
To start the tool, move the switch lever to
the
"ON"
position. To stop, move the
Switch
lever
switch lever to the
"OFF"
position.
CAUTION
