● After adjustment, place a screw into the end of the rail groove. Tilt the
rail and check that the screw moves smoothly to the stopper position.
(See Picture 12)
● After checking, reverse the procedure for removing the rail to reattach it.
(Fix the screws when the rail makes contact with the machine.)
Note: If the front and rear rail xing screws are not loosened, the rail can-
not be attached to the correct position.
● Put a screw into the rail groove, just beneath the holding plate, and adjust the holding plate height so that there is an
adequate gap between the holding plate and the rail groove for the screw head. Loosen the holding plate xing screw
and adjust the gap between the holding plate and rail groove. (See Picture 10) Removing the holding plate before ad-
justment will allow you to easily place screws into the rail groove easily. (See Picture 11) If the gap between the hold-
ing plate and the rail grove is too wide, screws may fall out. If the gap is too small, the screws may not be able to pass
through. Set the gap to between 0.2 to 0.5mm above screw heads. If you are using long screws, adjust the gap so that
it is a little higher.
Note: When using washer head screws, make the gap wider. If the gap between the holding plate and the rail groove is
not wide enough, washers may become stuck between the holding plate and the rail causing the screw ow to stop.

● Adjustment is necessary if the screw ow is not smooth or if there is too much rail vibration.
○ Adjust the Amplitude control dial on the back of the machine using the precision screwdriver.
○ Adjust the Vibration frequency control dial on the back of the machine using the precision screwdriver and nd the
resonance point.
Adjust these dials to locate the optimum conditions for smooth movement of screws.
● Maximize the amplitude and adjust the vibration frequency to locate the resonance point (frequency when the rail vi-
bration is at a maximum.) Then turn down the amplitude to locate the optimum conditions for smooth movement of
screws.
● Although it is not recommended, the rail vibration can be adjusted while the machine is operating.
● During control dial adjustment, do not force the screwdriver beyond its rotation limits.
● The rail vibration has been adjusted before shipment using screws that correspond to the rail size.
(Refer to the label number on the rail for the nominal screw diameter: e.g. 17 is φ1.7)
● Put 2 or 3 screws into the rail groove and turn the machine on.
● No adjustment is necessary if the screws move to the stopper position smoothly. (See Picture 13)
●When the number of screws is low and no screw is picked up in a given period of time, vibration will become the
maximum and it will stop operation after that. (Refer to 4-2 “Basic Operation.”)Adjustment of volume is not effective
at the time of a forced oscillation.
● After it stops, turn on the machine again and repeat the above procedure.

5 - 7. Timer Adjustment
The machine is equipped with a screw sensor that detects the number of screws on the rail.
If a screw accumulates to some extent on a rail, operation of a scooping block will stop and vibration will stop after
timer set time.
The timer should normally be set to “Min.”
However if screws are moving slowly, it may be necessary to set the timer to “Max.”
● Adjust the Timer control dial on the back of the machine using a precision screwdriver. (See Picture 16)
● Turn the dial clockwise to reduce the vibration time. Turn it counterclockwise to increase the vibration time.
● During control dial adjustment, do not force the screwdriver beyond its rotation limits.
● Set the timer after checking that the rail is lled and that the screws are properly aligned.
● Use the provided screwdriver for adjusting the timer.

ment. However, if you are using screws outside the specications in this manual,
the machine may not work properly. In this case check and readjust the following:
Adjust the sensor levels for when screws are on the rail and for when no screws
are on the rail.
Remove the rear cover of the machine to check the IC on the printed circuit board.
(See Picture 17)
Measure the voltage level using Pins 3, 5, and 7 on the IC4050. Ground the metal
part of the body. (Use testing clips for the voltage measurement. Recommended
item: Testing clip <FP-7> manufactured by Sunhayato Corp.)
*** Screw Sensor Adjustment (Pin 3) ***

● Adjust the scooping chamber to its lowest position by turning the power to the machine on and off.
● Fill the scooping chamber with screws up to 2mm below the rail groove.
● Be sure not to cover the front of the sliding plate with screws.
● Always ensure there are adequate screws for the operation.
6 - 1. Number of Screws
6. Basic Operation
The driving motor repeats normal rotation and an inversion for about 2 seconds at a time, and the scooper carries screws
to the rail. The vibrator (solenoid) continuously sends screws to the front stopper to be picked up using the screwdriver.
Note:
If no screws are sent for approximately 10 seconds, vibration of a rail becomes stlonger. (The vibration sound, also, in-
creases; however, this is not a problem.)
If no screw is not detected for about 20 more seconds, then the machine stops operating. When you want to start opera-
tion again, turn the power switch OFF and ON again or a stopper is operated (extraction sensor perception),
View from the Above
Do not cover the front of the sliding plate with screws. Picture 2

- 18 -
6 - 2. Operation Check
● If each part is adjusted appropriately, screws are sent to the stopper.
● Pick up screws from the stopper using the electric screwdriver. Using the bit guide as a guide, pull the screwdriver
downward. Fit the screwdriver bit into the cross slot of the screw and then pull the screwdriver toward you in a hori-
zontal direction to pick up the screw. (See Picture 3)
● Do not use force when tting the screwdriver bit to the screw head. This may bend the rail or lead to malfunction of the
machine.
● To t the bit securely into the cross slot of the screw, slightly rotate the screwdriver bit.
● Select the screwdriver bit according to the nominal diameter of the screws you are using. (Refer to “4-1. Model Type.”)
● If screw alignment or ow is abnormal, check and adjust each part. (Refer to “4-1. Model Type”)
● Pull the screwdriver downward and fit the
screwdriver bit into the cross slot of the screw.
● Pull the screwdriver toward you in a horizontal
direction to pick up the screw.

7 - 2. Maintenance
Dust, dirt, or grease in the rail groove may reduce the screw feeding speed.
If dust, dirt, or grease is evident in the rail groove, wipe it with a soft, clean alcohol-soaked cloth. Remove the rail if it is
hard to wipe.
Be sure to turn off the machine and remove all screws from the scooping chamber before removing the rail. (Refer to
Page 9 “4-5-1. Height Adjustment of Passing and Holding Plates (How to Remove the Rail)”)
Please replace the rail if there is noticeable grease, dirt or scratch on it.
7. Miscellaneous
7 - 1. Overload Protection Circuit
The machine is equipped with an overload protection circuit.
Normally, the driving motor rotates and sends screws to the rail.
However, if an overload is applied to the machine’s moving parts, the driving motor rotates in the counter
direction for a given length of time and then rotates normally again.
If this action recties the overload, the machine resumes screw feeding; however, if there is still an overload,
the motor continues to rotate in normal and opposite directions and then the power to the motor is cut off.
If the power to the motor is cut off, turn off the machine and remove the cause of overload.
For example, if there are too many screws in the scooping chamber, remove some of them. Remove any
screws stuck in the machine’s moving parts.
After eliminating the cause of overload, turn the machine on and restart operation. (Power reset)
