5-2. Amount of screws to be loaded
An excessive amount of screws, loaded into the chamber, will have an
adverse effect on the screw alignment and transport. The gure, shown
at right, indicates the maximum amount of screws to be loaded. Use
this as a guide when loading the screws.
・ Turn the power switch ON and OFF so that the scooping block is at the
lower limit position.
・ Load screws up to approximately 2-3 mm below the rail surface.
・ At this time, check that screws are not loaded so as to cover the upper
portion of the inclined plate.
・ Be sure to determine the screw load by observing the machine while it is
in operation.

○Loading the screws (cf. p7)
・
Open the upper cover.
When the chamber plates are at their lowest position, load screws up to 2-3 mm below the rail groove surface.
・
Check that the screws are not loaded so as to cover the upper portion of the inclined plates.
[CAUTION] Do not overload the chamber with screws otherwise it may cause a malfunction or damage the machine.
○Turning ON the power
・
Plug the attached AC adapter into the main body and power outlet.
[CAUTION] Do not use any AC adapter other than the one included with this unit, as it may cause damage.
・
When the power switch is turned ON, the power switch lamp lights up. The scooping block starts to move up and down. The rail
starts to vibrate and the escaper starts rotating.
・
Screws move along the rail towards the rotating escaper which selects one screw at a time.
・
The escaper rotates and deposits the selected screw at the extraction site.
・
At this moment, the sensor detects a screw and the screw sensor LED lights up and then the operation stops.
・
Until a screw is extracted, the machine stops operating.
・
When a screw is extracted, the sensor detects this and the sensor LED light goes off and the machine resumes operation.
○Pick uping Screws
・
Screws can be extracted with an electric screwdriver using a magnetized bit.
・
Use the bit guide to put the screwdriver down vertically into the screwhead’s slots, then pull the screwdriver, horizontally, to-
wards you as extracting the screw.
To insert the screwdriver bit into the screwhead slots properly, it may be necessary to twist the driver slightly.
