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 knob
and lower the tool body until the bit just touches the flat
surface. Tighten the lock knob 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 knob 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
By turning the nylon nut, 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 nylon nut 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 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.
•
Do not lower the nylon nut too low, or 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 bolt height, turn the hex bolts with a
screw driver or wrench. The stopper block is also
convenient for making three passes with progressively
deeper bit settings when cutting deep grooves.
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 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.
Speed adjusting dial
For RP1110C
Fig.5
The tool speed can be changed by turning the speed
adjusting dial to a given number setting from 1 to 5.
Higher speed is obtained when the dial is turned in the
direction of number 5. And lower speed is obtained
when it is turned in the direction of number 1.
This allows the ideal speed to be selected for optimum
material processing, i.e. the speed can be correctly
adjusted to suit the material and bit diameter.
Refer to the table for the relationship between the
number settings on the dial and the approximate tool
speed.

CAUTION:
•
The speed adjusting dial can be turned only as far
as 5 and back to 1. Do not force it past 5 or 1, or
the speed adjusting function may no longer work.
ASSEMBLY
CAUTION:
•
Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.
