Adjusting the depth of cut (Fig. 3)
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" gradua-
tion. 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 adjust-
ing 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
bolt of the stopper block.
Nylon nut (Fig. 4)
CAUTION:
• Do not lower the nylon nut too low or the bit will pro-
trude dangerously.
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.
Stopper block (Fig. 5)
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. Adjust the two remaining hex bolts to obtain shal-
lower 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
progressively deeper bit settings when cutting deep
grooves.
Switch action (Fig. 6)
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 con-
tinuous operation, pull the trigger and then depress the
lock button further.
To stop the tool, pull the trigger so that the lock-off button
returns automatically. Then release the trigger. After
releasing the trigger, the lock-off function works to pre-
vent the switch trigger from being pulled.
Speed adjusting dial (Fig. 7)
For RP1110C
The tool speed can be infinitely adjusted between 8,000
-1
and 24,000 min by turning the speed adjusting dial.
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 below for the relationship between the
number settings on the dial and the approximate rotating
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.
Operation (Fig. 8)
• Set the tool base on the workpiece to be cut without the
bit making any contact. Then turn the tool on and wait
until the bit attains full speed. Lower the tool body and
move the tool forward over the workpiece surface,
keeping the tool base flush and advancing smoothly
until the cutting is complete.
• When doing edge cutting, the workpiece surface
should be on the left side of the bit in the feed direction.
NOTE:
• Make sure that the tool raises automatically when the
lock knob is loosened. The position of the bit must be
higher than the tool base.
• Also, make sure that the dust guide is installed prop-
erly.
• Moving the tool forward too fast may cause a poor qual-
ity of cut, or damage to the bit or motor. Moving the tool
forward too slowly may burn and mar the cut. The
proper feed rate will depend on the bit size, the kind of
workpiece and depth of cut. Before beginning the cut
on the actual workpiece, it is advisable to make a sam-
ple cut on a piece of scrap lumber. This will show
exactly how the cut will look as well as enable you to
check dimensions.
• When using the straight guide, be sure to install it on
the right side in the feed direction. This will help to keep
it flush with the side of the workpiece.
