7 - 2. Maintenance
Dust, dirt, or grease in the rail groove may reduce the screw feeding speed.
If dust, dirt, or grease is evident in the rail groove, wipe it with a soft, clean alcohol-soaked cloth. Remove the rail if it is
hard to wipe.
Be sure to turn off the machine and remove all screws from the scooping chamber before removing the rail. (Refer to
Page 9 “4-5-1. Height Adjustment of Passing and Holding Plates (How to Remove the Rail)”)
Please replace the rail if there is noticeable grease, dirt or scratch on it.
7. Miscellaneous
7 - 1. Overload Protection Circuit
The machine is equipped with an overload protection circuit.
Normally, the driving motor rotates and sends screws to the rail.
However, if an overload is applied to the machine’s moving parts, the driving motor rotates in the counter
direction for a given length of time and then rotates normally again.
If this action rectifies the overload, the machine resumes screw feeding; however, if there is still an overload,
the motor continues to rotate in normal and opposite directions and then the power to the motor is cut off.
If the power to the motor is cut off, turn off the machine and remove the cause of overload.
For example, if there are too many screws in the scooping chamber, remove some of them. Remove any
screws stuck in the machine’s moving parts.
After eliminating the cause of overload, turn the machine on and restart operation. (Power reset)
