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 (9/16”) at a pass when cutting
grooves with an 8 mm (5/16”) diameter bit.
• When cutting grooves with a 20 mm (13/16”) diameter
bit, the depth of cut should not be more than 5 mm
(3/16”) at a pass.
• For extra-deep grooving operations, make two or three
passes with progressively deeper bit settings.
Stopper block
The stopper block has three adjusting hex bolts which raise
or lower 0.8 mm (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 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 pro-
gressively deeper bit settings when cutting deep grooves.
Switch action
CAUTION:
• Before plugging in the tool, always check to see that the
tool is switched off.
• Switch can be locked in “ON” position for ease of
operator comfort during extended use. Apply caution
when locking tool in “ON” position and maintain firm
grasp on tool.
To start the tool, move the switch lever to the I (ON) position.
To stop the tool, move the switch lever to the O (OFF) posi-
tion.
