Adjustment of the tilting bolts
- As the original setting, the automatic screw feeder shall be horizontal when set on a surface. Depending on specific type of screw applied, there may be cases that the screws cannot move smoothly. At such instance, please check the “Adjustment of the rail” section listed in this operation booklet, or adjust tilting angle of the machine as necessary:
- The tilting bolts are located on bottom rear end of the machine.
- When these bolts are used, they shall be set at the same height and angle on both sides.
- Since the bolts do not have stoppers equipped inside, please be careful not to detach them from the machine body.
- After the adjustment, please verify if screw delivery functions properly before application.
◆ 
Check/adjustment of rail vibration
Transfer speeds of screws differ according to screw type. This machine can change rail amplitude and adjust the transfer speed.
* To adjust amplitude, loosen an amplitude xing screw at the rear of
this machine and turn the amplitude adjusting screw at the bottom of the machine. Viewing it from the bottom, if turned clockwise, the amplitude becomes larger, and if turned counterclockwise, the amplitude becomes smaller. * If you make the amplitude too large in order to speed up the transfer,
it may become difcult to pull up screws. So, adjust it to appropriate
amplitude for the type of screw being used.
* After adjustment is completed, be sure to tighten the amplitude xing
screw on the rear of the machine.

Check of the sensor’s optical axis
If there is no screw at the stopper section, this machine continues operation, and if there are screws, it stops after a certain period of time has passed. This machine has the level of the screw/no screw sensor adjusted by the reference rail on shipment. In reality, however, a level adjustment of the sensor may become necessary when using thin-head screws or due to occurrence of variation on rail replacement. Then, follow the directions (1) and (2) for the adjustment.
(1)
- Loose the sensor attaching screw on the side lit up as much as it moves by picking up the sensor holder with ngers,
and turn on the power switch.
- Place a screw on the fail within the sensor range.
- Hold the rail end lightly with ngers as much as it doesn’t vibrate so that screws doesn’t pass through.
- When the sensor holder is moved up and down, there is a position the sensor of the receiving light side defects a screw head and stops the vibration.Tight the sensor attaching screw at this position.
- Comrm whether it really works or not. See if a screw passes through and the sensor detects if and stops.
(2)
* Remove the machine body rear cover, and measure the voltage level. Adjust the IC4050 7th-pin voltage level. The ground, when mea­suring it, is the body’s metal part. * Adjustment is not necessary if the voltage level is within 0.25 to 1.5V when a rail is and if there is no screw at the stopper section. * When adjustment is necessary, loosen the sensor attaching screw on the side. Adjust the voltage level by moving it up and down. (It is easier to make an adjustment if connector of the main motor is removed.) * After the adjustment, throw in the screws and run it practically in or­der to check the operation.
Note: When no loaded screws are: 0.25 V to 1.5 V When loaded screws are: 3.5 V or more

◆ 
Adjustment and Check of the timer
he speed of screw delivery depends on the actual kind of screw. By adjust­ing the timer of the machine the screws are picked up smoothly. * If a screw is picked up on the stopper and the screw coming next is not picked up for a certain amount of time, the unit stops the operation. Then if you pick up the screw, it starts operating again. You can change the time by adjusting the timer within 1 to 6 seconds. * Time changes after adjusting the times setting volume on the rear of the machine as shown on the right. Viewing the unit from the back, if it’s turned clockwise, the time becomes longer, and if it’s turned counterclockwise, the time becomes shorter. * Do not use excessive force while making an adjustment. Turn it only as much as the possible rotating range allows.
◆ 
The operation check of the overload protection circuit
For overload detection and check of protection circuits: Try to force the movement of the scooping block to stop, to check the opera­tion of overload detection and overload protection circuits. If you force the movement of the scooping block to stop for about 4.5 sec­onds or less, the main motor stops after repeating rotations of
reverse -> forward -> reverse -> ....
To cancel the above operational check, turn off and then turn on the power switch again.
Caution : Use the screwdriver provided with the machine. Using other screwdrivers may damage circuit components.
