11. Be careful of the bit rotating direction and the feed
direction.
12. Do not leave the tool running. Operate the tool
only when hand-held.
13. Always switch off and wait for the bit to come to a
complete stop before removing the tool from
workpiece.
14. Do not touch the bit immediately after operation; it
may be extremely hot and could burn your skin.
15. Do not smear the tool base carelessly with
thinner, gasoline, oil or the like. They may cause
cracks in the tool base.
16. Draw attention to the need to use cutters of the
correct shank diameter and which are suitable for
the speed of the tool.
17. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
18. Always use the correct dust mask/respirator for
the material and application you are working with.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting the depth of cut (Fig. 1)
Place the tool on a flat surface. Loosen the lock lever and
lower the tool body until the bit just touches the flat
surface. Tighten the lock lever to lock the tool body.
Turn the stopper pole setting nut counterclockwise. Lower
the stopper pole until it makes contact with the adjusting
bolt. Align the depth pointer with the “0” graduation. The
depth of cut is indicated on the scale by the depth pointer.
While pressing the fast-feed button, raise the stopper pole
until the desired depth of cut is obtained. Minute depth
adjustments can be obtained by turning the adjusting
knob (1 mm per turn).
By turning the stopper pole setting nut clockwise, you can
fasten the stopper pole firmly.
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 of the stopper block.
Nylon nut (Fig. 2)
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.
Stopper block (Fig. 3)
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.
Switch action (Fig. 4)
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.
Speed adjusting dial
For model RP2300FC, RP2301FC only (Fig. 5)
The tool speed can be changed by turning the speed
adjusting dial to a given number setting from 1 to 6.
