4-5. Checking and Adjusting the Rail Assembly and Escaper Components

Bit guide assembly retaining screw

The machine is factory adjusted for pan-head screws prior to shipment. Under normal
conditions, you do not have to readjust the rail assembly or escaper components.
However, if the employed screws have an extremely thin head or a smaller diameter,
it may be necessary to perform a check/adjustment procedure. To check or adjust
the rail assembly and escaper components, you have to remove the four mounting
screws to take off the escaper cover.
NOTE: After the rail has been removed for cleaning or the rail or escaper has been
replaced for a change in the employed screw size, be sure to adjust theescaper components and rail assembly. The replacement procedures aredetailed in Section 6-3, Replacement Procedures.

MountingscrewsWhen the employed screws move along the rail, the escaper receives one of them andmoves it to the screw removal section (sensor optical axis). In this state, the employedscrew is retained in the removable position. The employed screw can be removed only
when the escaper is positioned as shown at right. When you remove the screw fromoutside, the escaper operates to receive the next screw and retains it in the removable
position. When there is no screw in the removable position, the escaper continues its
reciprocating motion. The escaper operation is controlled by the sensor.
If the employed screw has an extremely thin head, the sensor may fail to detect it. If
the sensor does not achieve detection, the escaper does not stop running even if it
retains the employed screw. In such an instance, you have to complete the following
adjustment procedure.
Turn off the power switch and let an employed screw be retained by the escaper.

NOTE: If you lower the sensor bracket assembly to excess, the sensor actuates toinhibit the escaper from operating even when the escaper does not retain an
employed screw.
(Reference)
You can observe the sensor output voltage level when you remove the main
body rear cover and measure the voltage with the pin 7. Note that the metal
portion of the unit provides a signal ground.
The measured voltage should normally be as follows:
When there is a screw in the removal section: 3.5V or higher
When there is no screw in the removal section: 0.25 V - 1.5V or lower

5-1. Loading the Screws

Rail

Remove the screw bin lid.

Approx. 3 mmWhile the bin dipper plates are at the lowest position, you canpour in the screws until they are piled up to about 3 mm fromthe rail upper surface. Ensure that the screws are equallydistributed into the right- and left-hand bins.

the screws to excess.

5-2. Operating the Machine

Connect the accessory AC adapter plug to the DC jack on the rear of the machine. Connect the AC adapter to a power outlet.
Turn on the machine power switch. The lamp incorporated in the power switch then comes on.
Turning on the power switch causes the drive motor to rotate normally, the bin dipper plates to move up and down, and the rail tovibrate. The escaper reciprocates at the same time. After a while, the loaded screws are sequentially transported along the rail
groove and delivered to the escaper. The escaper picks a screw and retains it in the removable position. If you do not remove
the screw from the removable position for a predetermined period of time, the machine comes to a stop. The moment the screw isremoved, the machine resumes operation.

Operational features
The machine is equipped with an overload protection circuit.
If a movable section is overloaded during a machine operation due, for instance, to a trapped screw or other article or excessive screw
introduction into the screw bins, the overload protection circuit actuates.
Function descriptions and remedies
Under normal conditions, the drive motor in the 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 rotates inreverse direction for a predetermined period of time and then resumes its normal rotation. When the cause of the movable section overload
is eliminated upon motor reversal, the motor reverts to normal rotation, permitting you to obtain the screws continuously.
If the cause of the movable section overload is not eliminated 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 the power supply to the drive motor. In thisinstance, however, the escaper continues operating.
When the power to the drive motor shuts off as above, turn off the power switch and then eliminate the cause of the overload. If, for instance, 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, remove it.
After the cause of the overload is eliminated, turn the power switch back on (power-on
reset) and use the machine.

Timer setting
Increase

Decrease

The machine is equipped with a timer.
You can adjust the timer setting as appropriate for the employed screw type.
Function descriptions
The screw feed speed varies with the employed screw type.
The machine continues running while there is no screw in the screw removal areaof the escaper section. It stops its operation when a predetermined period 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 machine.
It is recommended that you decrease the timer setting when the feed speed for theemployed screw type is high and increase the setting when the feed speed is low.
When adjusting the timer setting, exercise care not to rotate the control beyond thepermissible range.
