4. Making checks and adjustments before use
4-1 Checking model number
• Ensurethat the screw driver bit used matches the size of the screw
thread.
The compatible screw thread is shown on the rail section (Image 1).
Check the rail section for this information.
• Adjustmentsand checks are made to each section of the unit when
ordered, to match the screws used (M1.0 to 1.7 <flat head>/M2.0 to 3.0
(pan head).
• Thefactorydefaultsettingscanbeusedforthemajorityofscrews.
However, if the screw head height or shape differs and causes the unit to
operate abnormally, further adjustments of each section may be required.
In this case, check and adjust the following areas.
 Check the screw capacity
 Check and adjustment of rail oscillation
 Check and adjustment of passing plate・holding plate
Check and adjustment of rail oscillation
Check and adjustment of bit guide
 Check and adjustment of timer
 Check and adjustment of sensor voltage levels
• Therailcanbereplaced easily and quickly in this device to allow different
sized screw threads to be used.
Fine adjustments may be required after replacement of the rail.
These adjustment methods are outlined in a separate section. Please
read the relevant section first.
Caution Adjustments should only be made with the power switch in the
OFF position.

4-2 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 stronger.
(The vibration sound, also, increases; however, this is not a problem.)
If no screws is not detected for about 20 more seconds, then the machine stops operating. When you want to start operation again,
turn the power switch OFF and ON again or a stopper is operated (extraction sensor perception).
4-3 Screw capacity
Placing too many screws into the hopper can adversely affect the alignment and transport of screws.
The image below (Image 2) is the maximum capacity and should be used as a guide to filling the hopper.
• TurnthepowerswitchON-OFFandensurethatthepanningblockisatitslowestposition.
• Fillthehopperwithscrewsuptoapointapproximately2mmbelowtherailentrance.
• Checkthatthefrontoftheslopedplateisnotcoveredbyscrews.
• Constantlycheckthattheoptimumscrewlevelismaintainedduringoperation.
Ensure that the front of the sloped plate remains visible

4-4 Check of operation
• Ifeachsectionhasbeenadjustedcorrectly,screwswillbetransportedtothestoppersection.
• Screwsinthestoppersectioncanbetakenoutwithanelectronicscrewdriver.
The screw driver should be vertical using the bit guide as a guide. The screw driver should then be briefly rotated and moved
horizontally to take the screw (Image 3).
• Donotapplyexcessiveforcewhenmovingthescrewdriverhorizontally(whenmatchingthebittothescrewhead).
Rotating the screw driver bit briefly makes it easier to line up the bit with the cross in the screw thread.
• Ensurethatthescrewdriverbitmatchesthatofthescrewbeingused.(Referto4-1Checkingmodelnumber)
• Checktheadjustmentofeachsectionifyoubelievethescrewalignmentandtransportisnotoperatingcorrectly.4-5 Adjusting
the height of the brushes
• Placethescrewdriververti-
cally and line up the bit with the
cross on the screw head.
• Movethescrewdrivertowards
you into a horizontal position.

4-5 Adjusting the height of the brushes
No adjustment is required if the brushes rotate at a height where they come in contact with the screw heads going into the rail
groove when the power is switch on.
• TurnthepowerOFFiftheheightofthebrushesrequiresadjustment.
• Ifadjustmentisrequired,loosenthebrushheightadjustmentscrew(Image4-1).
Move the brushes by hand and make adjustments by checking that the head of the screws entering the rail groove come in
contact with the brushes (Image 4-2).
• Ifthebrushesaresettoohigh,misalignedscrewsmaynotbesweptup.
• Ifthebrushesaresettoolow,thescrewsmaybethrowntooneside,orthebrushesmaynotrotate.

mounting screw to ensure that the gap in the passing plate is sufficient.
Screws can become easily jammed if this gap is too large. If there is no gap, the screws cannot pass through.
The ideal gap is one that allows the screws to just pass through.
A passing plate compatible with specially shaped screws, such as those with low heads, is available.
A new passing plate can be designed upon request if details of the screws to be used, or their dimensions, are provided.

• After adjustment is complete, insert a screw to be used into rear of the rail
groove and tilt the rail. Check that the screw moves to the stopper section
without any jamming (Image 12).
• Aftercheckingthis,reassembletherailintothedeviceinthereverseorder.
(When reassembling the rail, insert it into the device as far as it goes and
tighten the screw).
Note) Front/rear: The rail cannot be inserted into the correct position if the rail
mounting screw is not loosened.
• Theholdingplatedropsscrewstobeusedintotherailgroovedirectlybelowtheholdingplate.Adjusttheheightoftheholding
plate mounting screw to ensure that the gap is sufficient. (Image 10)
<Remove the holding plate and drop a screw into the groove to allow easy adjustment> (Image 11)
Screws may be thrown out if this gap is too large. If there is no gap, the screws cannot move.
The ideal gap size is between 0.2 and 0.5mm. The gap can be slightly larger if the screw thread is long.
Note) The gap should be made larger if screws with plain washers are used.
Washers may hit each other if the gap is small, causing jamming of the holding plate, stopping movement of the screws.

Adjustment is required in the following cases.
• Ifscrewsdonotmoveeasily,orjumpaboutintherail:
→Rotate the oscillation amplitude adjustment volume knob at the rear of the device with a precision screw driver.
→Rotate the oscillation frequency adjustment volume knob at the rear of the device with a precision screw driver until a
resonance point is found.
The two volume knobs above should be adjusted until the optimum operating condition is found.
• To find the optimum operating condition, first maximize the oscillation amplitude and adjust the oscillation frequency until a
resonance point (the frequency at which the rail oscillates the most) is found. Then adjust the oscillation again until it is smaller.
• Whileadjustmentscanbemadewhenthedeviceisoperating,itisrecommendedthatoscillationsbeadjustedbeforeuse.
• Donotapplyexcessiveforcewhileadjustingthevolumeknobs,andadjustthemonlywithintherangethattheycanberotated.
4-6 Checking and adjusting rail oscillations
• Thefactory setting for oscillation suits ordinary purpose screw thread sizes that can be used with the supplied rail.
(Check the rail thread size on the label at the front of the rail. Eg: 17 means a M1.7 thread)
• Place2or3screwstobeusedintotherailgrooveandturnthepoweron.
• Noadjustmentisrequiredifthesescrewsmovesmoothlytothestopper(Image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 effect at the time of a forced oscillation.
•Afteritstops,turnonthemachineagain
and repeat the above procedure.

4-8 Checking and adjusting the timer
This device includes a sensor to detect a rail full with aligned screws.
If a screw accumulates to some extent on a rail, operation of a scooping block will stop and vibration will stop after time set time.
The timer is usually set to MIN.
However, with screws that are taking time to become lined up, the timer is better set to MAX.
• Adjustthetimervolumeknobattherearofthedeviceasshownbelow(Image16).
• Whenviewingfromtherear,clockwiseshortensthetime.
Anti-clockwise lengthens the time.
• Donotapplyexcessiveforcewhileadjustingthevolumeknobs,andadjustthemonlyintherangethattheycanberotated.
• Checkhowthescrewsarebeingaligned,andadjustthetimerappropriately.

4-9 Checking and adjusting the sensor voltage level
The sensor level in the device can be used with the majority of screws with its default settings.
However, differences in screw head height and shape, or if the rail has been
replaced, mean that the device may not operate correctly, therefore requiring
further adjustment.
Adjust the sensor level for when there are screws on the rail and for when there
are no screws on the rail.
The IC to be checked can be seen on the control board after remove the device
cover (Image 17).
The voltage level is set using pins 3, 5, and 7 of IC4050 on the control board.
Metal parts of the device are grounded during this process.
(A test clip can be used to make measuring the voltage easier. The
recommended product is the FP-7 test clip made by Sunhayato Corporation.
Adjusting the full rail sensor <using pin number 3>.
This sensor detects the number of screws on the rail.
Loosen the full sensor light receptor mounting screws (2 places) and move up
or down by rotating the bracket (Image 18).
If there are no screws to be used present, the voltage should be between 0.25
and 1.5V. If there are screws present, the voltage should be 3.5V or greater.
A voltage of 2.5V is used as the electronic threshold for determining the
presence of screws.

Adjusting the screw feed sensor <using pin number 5>
This sensor detects movement of the stopper.
Loosen the stopper sensor bracket mounting screws (2 places) and adjust the
light receptor in a sideways direction. (Image 19)
The sensor level is adjusted so that it is 4V or greater with the stopper in the
ON position, and 0.2V or less with the stopper in the OFF position.
A voltage of 2.5V is used as the electronic threshold for determining the
presence of screws.
Adjusting the tip sensor <using pin number 7>
This sensor detects the presence of screws in the stopper.
Loosen the tip light receptor sensor bracket mounting screws (2 places) and
move up or down by rotating the bracket (Image 20).
If there are no screws to be used present, the voltage should be between 0.25
and 1.5V. If there are screws present, the voltage should be 3.5V or greater.
A voltage of 2.5V is used as the electronic threshold for determining the
presence of screws.
Once adjustment of each section has been completed, check the actual
operation of the device with screws to be used.
If there are any faults in the operation of the device, the adjustments above will
need to be performed again, in addition to adjusting the rail oscillation and front/
rear positioning.
After checking the operation of the device, return all wiring to its original state.
Caution Ensure that the wiring does not become jammed or interrupt the
operation of moving parts.

5. Maintenance
The transport speed of screws to be used may become slower if the rail groove becomes dirty.
If the rail is extremely dirty, use a thin cloth soaked in alcohol to clean the rail groove. The rail can be removed from the device
if you find it difficult to clean the rail. If removing the rail, ensure that the power is turned off and screws inside the panning area
removed. (Refer to “Making checks and adjustments before use” for information on how to remove the rail).
Replacement of the rail is recommended if the rail groove is so dirty or damaged that it affects operation of the device.
6. Replacement and adjustment of parts
The brushes, drive belt, and drive motor are expendable items.
Replacement rails for different sized screw threads are to be ordered separately.
The replacement and adjustment method is outlined separately.
Please read the instructions carefully before making adjustments. Remove all screws within the device before replacing parts.
Caution Replacement and adjustment should only be performed with the power switch in the OFF position.
