The upper limit of the tool body can be adjusted by
turning the nylon nut.
CAUTION:
•
Do not lower the nylon nut too low. The bit will
protrude dangerously.

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 with a
screwdriver or wrench. The stopper block is also
convenient for making three passes with progressively
deeper bit settings when cutting deep grooves.
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.
•
For extra-deep grooving operations, make two or
three passes with progressively deeper bit
settings.

CAUTION:
•
Before plugging in the tool, always check to see
that the switch trigger actuates properly and
returns to the "OFF" position when released.
•
Make sure that the shaft lock is released before the
switch is turned on.
To prevent the switch trigger from being accidentally
pulled, a lock button is provided.
To start the tool, depress the lock button and pull the
switch trigger. Release the switch trigger to stop.
For continuous operation, pull the switch trigger and
then depress the lock button further. To stop the tool, pull
the switch trigger so that the lock button returns
automatically. Then release the switch trigger.
After releasing the switch trigger, the lock-off function
works to prevent the switch trigger from being pulled.
CAUTION:
•
Hold the tool firmly when turning off the tool, to
overcome the reaction.
Electronic function
For model RP2300FC,RP2301FC only
Constant speed control
•
Possible to get fine finish, because the rotating
speed is kept constantly even under the loaded
condition.
•
Additionally, when the load on the tool exceeds
admissible levels, power to the motor is reduced to
protect the motor from overheating. When the load
returns to admissible levels, the tool will operate as
normal.
Soft start feature
•
Soft start because of suppressed starting shock.
