Makita RP0910 Instruction Manual page 7

To remove the bit, follow the installation procedure in
reverse.
CAUTION:
Do not tighten the collet nut without inserting a bit, or
the collet cone will break.
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 fast-feed button 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 fast-feed button clockwise, you can
fasten the stopper pole firmly.
Now, your predetermined depth of cut can be
obtained by loosening the lock knob and then lower-
ing 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
protrude 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
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 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
continuous 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 prevent the switch trigger from being pulled.
Speed adjusting dial (Fig. 7)
For RP1110C
The tool speed can be infinitely adjusted between
8,000 and 24,000 min
ing 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.
