Do not allow screws hide the top surface of the rail groove.
(The screws must be positioned about 2 to 3 mm lower than
the top surface of the groove.)
5. Getting the Feeder into Motion
5.1 Supply of Screws
Loading the feeder with too many screws could adversely affect their
alignment and transfer.
The approximate maximum supply of screws is illustrated in the figure
at right. Consult this figure in loading screws.
• Turn the power switch on, then off to move the scooping plate to the
lower limit position.
• Load screws to a position about 2 to 3 mm lower than the top surface
of the rail groove. Check to make sure that the top surface of the rail
groove is not hidden by the screws.
• Adjust the supply of screws by observing the behavior of the feeder in
operation.
This feeder comes with an overload protection circuit.
The protection circuit trips when the moving parts of the feeder are
overloaded, as by screws being stuck in the moving parts or too many
screws being put in the scooping chamber.
Actuation of the overload protection circuit
If the moving parts of the feeder are overloaded, the drive motor
reverses for a predetermined period of time and then returns to
forwarding. When the overload imposed on the moving parts of the
feeder no longer exists during reversing, the drive motor returns to
normal forwarding. If the overload imposed on the moving parts of the
feeder persists during reversing, the drive motor reruns the sequence
of reversing, forwarding, reversing, forwarding and so forth for a
predetermined period of time before it is powered off. The cutting disc
continues operating, though.
Thus explained, if the drive motor is powered off, turn off the power
switch and remove the overload imposed on the moving parts of the
feeder. For example, if you have put too many screws in the scooping
chamber, correct the supply of screws. If screws or any other objects
are stuck in the moving parts of the feeder, remove them.
After the overload has been removed, turn on the power switch to put
the feeder back into operation (power-on reset).
• A screw stock option, NEJIKURA is available which loads screws
automatically to maintain a metered count of screws to be loaded.
Please check us if you need this option. – 8 –

While the LCD panel LED is on, push the unloading lever
forward until it hits the stopper.
Screws will drop onto your palm at the same time.
The feeder, when just powered on, behaves differently
depending on the state in which it had been powered off.
The feeder won’t start unless you manipulate the unloading
lever.
Return your hand to front with care not to drop the screws off
your palm.
The LCD panel LED goes out and the feeder restarts.

5.6 Retaining Plate Check and Adjustment
Check the retaining plate position.
• Check that there is a clearance of about 0 to 1 mm between the head
of the working screw in the rail groove and the retaining plate.
• Without a clearance, screws could be stuck. Too large a clearance
could cause screws to overlap or cause them to pop out.
• If the retaining plate requires adjustment, adjust it.
• Loosen the bit guide assembly setscrew and turn the bit guide
assembly vertical adjustment screw counterclockwise with an Allen
wrench to move up the retaining plate or clockwise to move it down.
Make adjustments for a clearance of about 0 to 1 mm between the
head of the working screw.
• In clamping the bit guide assembly setscrew following the completion
of the adjustment, do so to maintain a parallel clearance between the
retaining plate and the rail.
Ensure that the clearance in the rear of the feeder is not smaller than
that in the front of the feeder.
• When the adjustment is complete, verify correct operations.
5.7 Timer Check and Adjustment
The working screw transfer speed varies depending on the screw type.
A longer timer interval setting is recommended for screws with a lower
transfer speed, and a shorter timer interval setting is recommended for
screws with a faster transfer speed.
• This feeder is designed to halt screw transfer with a certain delay after
a certain count of screws has accumulated at the unloading port. This
delay can be adjusted with the timer.
• A timer trimmer is found in the rear of the feeder as shown at right.
• Turn the trimmer clockwise when the feeder is viewed from the rear to
decrease the interval or counterclockwise to lengthen the interval.
• Adjust the trimmer within the range of its rotation, without using undue
force.
• Use the provided screwdriver for adjusting the timmer.
• Set an appropriate timer interval by verifying a correct feeder operation
on working screws.

5.8 External Output Signal Line
This feeder has an external output signal line, allowing for external
generation of a signal synchronized with the timing at which the LCD
panel LED lights up, as an open collector output. Use this output to
connect an indicator, buzzer or the like externally.
The signal line is housed inside the feeder. To use the signal line, lead
it outside through the grommet in the rear of the cover.

6. Maintenance
Turn off the power switch before performing check
and adjustment work.
Eject all working screws from within the feeder before
proceeding with maintenance work.
A dirty rail groove could slow down the working screw transfer speed. If
the rail groove is found noticeably soiled, wipe it off with a thin cloth
impregnated with alcohol.
If the rail groove is difficult to clean, the rail can be detached from the
feeder for cleaning. Before detaching the rail from the feeder, turn off the
power switch and remove the screws from the scooping chamber (to
prevent screws from falling out).
Remove two front cover mounting screws and move the front cover.
Remove the cutting disc assembly mounting screw and then detach the
cutting disc.
(See 7.3, “Replacing the Cutting Disc Assembly.”
Then, loosen the rail longitudinal position setscrew and pull out the rail
assembly to front.
The rail should require replacement if its rail groove is soiled or flawed to
impair its successful use.
If the rail assembly has been removed from the feeder, it is necessary to
make positional adjustments with the tip of the rail and the cutting disc.
• Align the groove rail and the groove in the cutting disc with each other.
• Mount the cutting disc assembly to keep the top surface of the groove
in the cutting disc lower than the top surface of the rail groove.
• Turn on the feeder and then make adjustments with the longitudinal
position of the rail so its tip will not hit the cutting disc when the rail
vibrates.
