3. Parts of Names
Note: ① The design of bit-guide has been changed form V-type to bowl-type since September,1998.
However, the operation method is same as the former V-type , therefore, the descriptions and the drawings for the Vtype are still used in this manual. Pleas be careful that the bit type have been changed.(See p.10)② A drop preventive plate is provided in this machine. However, this part should not be touched or maintained by users,
consequently, the explanations and the drawings for this part are omitted in this manual.

4-2. Checking and Adjusting he Brush
Check the height of the brush. Ensure that the brush check/adjustment procedure iscompleted 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 isapproximately 0 mm. In this instance, avoid lowering the brush too much. Aftercompletion of adjustments, tighten the brush mounting screws.
After the brush is properly adjusted, rotate it again to verify that it smoothly moves
without any obstruction.

Drop the employed screws into the rail groove. Slide the screws to thepassage window section and check or adjust the passage plate height.
Check that the clearance between the passage window upper end andthe 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, fine adjustments may beneeded.
For screws having a relatively long shank, however, coarse adjustments
will suffice.

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 tomove. The screws can move when the shutter is open with an adequate
clearance provided between the holding plate (screw guide1) and screw
heads.
When the clearance is 0 to 1 mm, the holding plate (screw guide1) heightneeds 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.

Tilt this machine or operate it so that the screws are delivered to therail assembly stopper. If there is no clearance between the holding
plate (screw guide1) 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) andscrew heads.
If the screws do not move to the escaper section, loosen the bit guideassembly 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 heightadjustment screw to provide a clearance of 0 to 1 mm between theholding 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 therail are the same on the rear end and the front end. After completionof adjustment, be sure to tighten the bit guide assembly retaining
screw.
If the employed screw has a relatively short shank, fine djustments
are needed. For screws having a relatively long shank, however,coarse adjustments will suffice.

Holding plate

Place five to ten screws in the rail and tilt this machine until
they hit the stopper on the rail assembly.
When the internal shutter is closed, the screws cannot go
through the passage plate. If it is closed, turn the timing shaft
clockwise with the Allen wrench to keep it open. The stopper
is fixed to the rail assembly. The adjustment of the stopper
is made by moving the rail assembly front and rear. If the “V”
groove on the bit guide and the rear point of the Phillips screw
head are not aligned, adjust as follows:
Loosen the bit guide mounting screw with the Allen wrench
and move the bit guide forward and back to put them in alignment.

Please remember to tighten the screws after adjusting.

Necessary adjustment when the bottom of the Phillips head of thescrew doesn’t match
Loosen the bit guide mounting screw with the Allen wrench and adjust
the position so that the “V” groove of the bit guide and the bottom of
the Phillips head of the screw match.
After making this adjustment, tighten the bit guide mounting screw.

<Replacement of the bit guide>     To change the bowl-shaped bit guide to the “V”
grooved bit guide, remove the bit guide mounting
screw and replace the guide.

5. Operating Procedures and Operational ChecksRail

5-1. Loading the Screws

Screw bin

Approx. 3 mm

Open the screw bin lid. While the bin dipper plates are at thelowest position, pour in the screws until they are piled up to
about 3 mm below the rail upper surface. Make sure thatscrews are equally distributed into the right-and left-hand bins.
CAUTION

5-2. Operating this machine
Connect the accessory AC adapter plug to the DC jack on therear 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, andthe rail to vibrate. After a while, the loaded screws aresequentially transported along the rail and delivered tothe stopper. If the screw is not picked up for an extended
period of time, the vibration will automaticallycome 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 theescaper 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 instance, when the screw bins are overloaded with screws, reduce the number of screws in the bins. If a screw or other article istrapped in a movable section, please remove it with tools. After the cause of the overload is eliminated, turn the power switch backon (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 whena predetermined period of time elapses after a screw is retainedin the removal section. This duration of time can be adjusted withthe 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.
