Check the height of the brush. Ensure that the brush check/
adjustment procedure is completed while the brush is placed in
a horizontal position as shown at right. To place the brush in a
horizontal position, rotate the timing shaft with the Allen wrench
supplied with the machine.
Please prepare the screws to be used. Drop a few of them into
the rail groove, check and adjust the brush height as directed
below.
After the brush is placed in a horizontal position as shown below,
rotate the brush. When the resultant gap between tip of the brush
and screw heads is approximately 0 mm, no adjustments are
needed.
If any adjustment is needed, perform the following procedure:
Loosen the brush mounting screws.
Make adjustments so that the gap between tip of the brush and
screw heads is approximately 0 mm. In this instance, avoid lower-
ing the brush too much. After completion of adjustments, tighten
the brush mounting screws.

Drop the employed screws into the rail groove. Slide the screws to the passage
window section and check or adjust the passage plate height. Check that the
clearance between the passage window upper end and the screw heads is not
greater than about 0.5 mm and that the screws can pass the passage window.
If the above requirements are not met, repeat above adjustment
procedures as needed.
After adjustment is completed, tighten the passage plate retaining screw. If the
screw applied has a relatively short shank, ne adjustments may be needed. For
screws having a relatively long shank, however, coarse adjustments will sufce.
Drop about 10 applied screws into the rail groove.
Tilt this machine or operate it so that the screws are delivered to the rail assembly
stopper.
If the shutter is closed or there is no clearance between the holding plate
(screw guide 1) and screw heads, the screws will not be able to move. The
screws can move when the shutter is open with an adequate clearance provided
between the holding plate (screw guide 1) and screw heads.
When the clearance is 0 to 1 mm, the holding plate (screw guide 1) height needs
no further adjustment.
NOTE: If the rail stopper captures a screw and brings the vibration to a stop
immediately, adjust the timer setting control on the rear side of the unit.

４-４．Checking and Adjusting the Holding Plate (Screw Guide 1)

If the holding plate (screw guide 1) height needs to be adjusted, please proceed as directed below.
Tilt this machine or operate it so that the screws are delivered to the rail assembly stopper. If there is no clearance between the hold-
ing plate (screw guide 1) and screw heads, the screws cannot move. The screws can move while the shutter is open with an
adequate clearance provided between the holding plate (screw guide 1) and screw heads.
If the screws do not move to the escaper section, loosen the bit guide assembly retaining screw, and rotate the bit guide assembly
up-down adjustment screw counterclockwise with the accessory Allen wrench to move the holding plate (screw guide 1) upward.
Adjust the holding plate (screw guide 1) height by rotating the bit guide assembly height
adjustment screw to provide a clearance of 0 to 1 mm between the holding plate
(screw guide 1) and the head of the screws.
When performing the above adjustment procedure, ensure that the gap between
the holding plate (screw guide 1) and rail is uniform. Please make sure that the gaps
between the holding plate and the rail are the same on the rear end and the front end.
After completion of adjustment, be sure to tighten the bit guide assembly
retaining screw.
If the employed screw has a relatively short shank, ne adjustments are needed.
For screws having a relatively long shank, however, coarse adjustments will sufce.
４-５． Checking and Adjusting the Rail Assembly
- ７-
Check the position of the stopper and sensor.
・Ensure that the rail is xed so that "A" portion of the stopper is

５． Operating Procedures and Operational Checks
５-１． Loading the Screws
Open the screw bin lid. While the bin dipper plates are at the lowest position,
pour in the screws until they are piled up to about 3 mm below the rail upper
surface. Make sure that screws are equally distributed into the right-and left-
hand bins.
Do not load the screws to excess amount.
５-２．
Operating this machine
Connect the accessory AC adapter plug to the DC jack on the rear of this machine, and the other side to a power outlet.
Turn on the main power switch. The lamp incorporated in the power switch will illuminate.
Turning on the power switch causes the drive motor to rotate normally, the bin scooper plates to move up and down, and the rail to
vibrate. After a while, the loaded screws are sequentially transported along the rail and delivered to the stopper. If the screw is not
picked up for an extended period of time, the vibration will automatically come to a stop. At the moment the screw is picked up, this
machine resumes operation.

Operational features
This machine is equipped with an overload protection circuit.
If a movable part is overloaded during a feeder operation, for instance, when a small screw or other particles is trapped, or
excessive screw is placed into the screw bins, the overload protection circuit will activate.
Function descriptions and remedies
Under normal conditions, the drive motor in this machine rotates in normal direction to feed the loaded screws continuously to the
escaper section, thereby allowing you to obtain the screws successively. However, if any movable section is overloaded, the drive
motor will rotate in reverse direction for a predetermined period of time and then resumes its normal rotation. When the cause of the
overload is eliminated upon motor reversal, the motor reverts to its normal rotation, resuming normal scret supply.
If the cause of the movable section overload is not cleared upon motor reversal, the overload protection circuit performs the
reverse rotation and normal rotation repetition cycle for a predetermined period of time and then shuts off power supply to the drive
motor.
When the power to the drive motor shuts off as above, please turn off the power switch and clear the cause of overload. For in-
stance, when the screw bins are overloaded with screws, reduce the number of screws in the bins. If a screw or other article is
trapped in a movable section, please remove it with tools. After the cause of the overload is eliminated, turn the power switch back
on (power-on reset) and resume operation.
This machine is equipped with a timer.
The timer setting can be adjusted according to the screw type.
Function descriptions
The actual screw feeding speed varies with screw type.
This machine continues running while there is no screw in the screw removal
area of the escaper section. It stops its operation when a predetermined pe-
riod of time elapses after a screw is retained in the removal
section. This duration of time can be adjusted with the timer setting control
on the rear of the feeder.
It is recommended that you decrease the timer setting when the feeding
speed is high, and increase the setting when the feeding speed is slow.
When adjusting the timer setting, please exercise care and do not rotate the
control beyond its permissible range.
