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 i s obtained. The depth of cut is
indicated on the scale (1 mm
or
1/16" 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
(5/8")
a t a
pass when cutting grooves with
a (1/4") diameter bit.
[Note: When cutting grooves with an (3/4") diameter bit, the depth of cut should not be
more than (1/4") a t a pass.] When you wish to cut grooves more than
(5/8")
deep with a
(1/4") diameter bit or more than (1/4") deep with an (3/4") diameter bit, make several
passes with progressively deeper bit settings.
Stopper block
The stopper block has three adjusting hex bolts which raise or lower 0.8 mm (about
1/32") 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
o f
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 the desired position.
The stopper block is also convenient for making three passes with progressively deeper bit
settings when cutting deep grooves.
