Basic operations
○Loading the screws
・
Turn the power switch ON and OFF so that the brush stops vertically above
the rail.
・
Open the top cover and load screws on the left and right side of the rail
evenly.
・
Do not load screws above the surface of the rail.
・
Be sure to determine the screw load by observing the machine while it is in
operation.
Screws with a diameter larger than 5 or longer than 20mm,
under the head, should not be loaded higher than the rail bottom.
○Turning ON the power
・
Use only the adapter supplied with this machine to connect it to a wall outlet.
When you turn the power on, the switch lamp lights up, the motor rotates and
screws are scooped onto the rail.
・
The rail vibrates to deliver screws towards the end of the rail, then the
escaper rotates to deliver screws to the pick up spot. When the screws come
to the stopper, the LED indicator lights up and the escaper stops rotating.
Rail cover
(INDICATION:The maximum screw load must not be
over 30mm below the rail-groove surface.)
Disassembled state
Do not load screws
above this point.

[CAUTION]
・The type and length of screw changes the load capacity so check and adjust
the load accordingly.
・Do not overload the hopper with screws otherwise it may cause a
malfunction or damage the machine.
・This machine accepts only steel screws. Plastic or stainless screws are not
accepted.
[CAUTION] Use only the AC adapter supplied with this machine
otherwise it may cause damage to the machine.

○Pick uping Screws
・
Pick up the screws at the stopper with the electric screw driver.
Use the bit guide to put the screwdriver down vertically into the screwhead's slots,
then pull the screwdriver, horizontally, towards you as pick uping the screw.
・
When inserting the screwdriver into the screwhead slots, do not use excessive force
as it may alter the position of the escaper or cause damage to the machine.
・
To insert the screwdriver bit into the screwhead slots properly, it may be necessary to
twist the driver slightly.
・
Use a driver bit which corresponds with the screw's diameter.
○Action of the escaper
・
The escaper rotates 90° clockwise--> stops for about 0.6 seconds
--> and rotates again 90° clockwise.
When a screw is caught in the escaper and the notch position is altered, the escaper
automatically rotates to the left, as a reference point run, in order to adjust the notch
position and then returns to the right rotation.
・
This machine continues its operation when no screw is found at the screw pick up
spot. The machine continues operating with a screw at the pick up spot but will stop,
after a certain lapse of time, if the screw is not picked up. After the screw is picked
up, the machine starts operating again. This time lapse can be varied by adjusting
the timer.
・
When no screw is found at the pick up site after a certain lapse of time, the rail
vibration increases.
(The vibration sound, also, increases however, this is not a problem.)
If no screw is still not found at the pick up site, then the machine stops operating. At
this time the escaper keeps rotating. When you want to start operation again, turn
the power switch OFF and ON again.

The rotation of the escaper, in the opposite
direction, is a reference point run of the escaper
motor.
The rotation of the escaper, in the opposite
direction, occurs when the power is turned on and
the starting point of the escaper is not alligned
with the reference point of the escaper motor.
During regular operation, as in the gure above,
the escaper rotates clockwise.

Adjusting the brush height
Load the screws into the scooping hopper, turn ON and OFF the
power switch so that screws are alligned into the rail groove.
・
Turn ON and OFF the power switch in order to set the brush to the
left as shown in the gure on the right.
・
Move the brush by hand to check that the screws, in the rail
groove, are in slight contact with the brush bristles and if needed
make the necessary adjustments.
・
When the brush height is too high or low, this will have an adverse
effect on the screw allignment and transport.
・
If any adjustment is necessary, loosen the brush height adjusting
bolt to adjust the brush height.
・
If the plastic portion, at the front of the brush, comes into contact
with the passing plate, loosen the brush assembly mounting screw
and move the brush assembly back so there is 0 mm clearance.
・
Turn ON the power switch to check that the brush operation is
normal.
Turn OFF the power switch before starting replacement and
adjustment.

Checking and adjusting the rail vibration
The amplitude and frequency of the rail vibration can be adjusted.
The vibration has been adjusted at the factory for screws that correspond with
the rail.
Put some screws into the rail and turn the power on. If they are delivered
smoothly, there is no need for adjustment.
The screw transport feed differs depending on screw type.
For screws with a low transport speed, or screws that easily jump, an
adjustment is necessary.

①
Turn the frequency adjusting knob (rst hole at the top in the
back of the machine) using the accompanying screwdriver.
Find the frequency at which the rail vibrates the most.
②
Turn the amplitude adjusting knob (second hole from the top)
and nd the amplitude for which screws are delivered smoothly.
・
If the vibration is adjusted to a too large a value to increase the transport
speed, screws may jump from the rail and fall into the machine from the
clearance, failing to unload screws normally.
Adjust the vibration to a proper value that matches the loaded screws.
・
With the accompanying screwdriver, turn the knob without using excessive
force.
・
When no screws are scooped onto the rail for a certain period of time, the rail
vibration increases. If, still, no screws are scooped on to the rail, the machine
stops operating.

・
If the rail comes into contact with the escaper, or the clearance between the
rail and escaper is too large, loosen the rail xing bolt, hold the rail groove
and adjust the rail assembly either backward or forward.
After making an adjustment, be sure to tighten the rail xing bolt.
・
When the rail comes in contact with the escaper, the escaper disk doesn't
rotate properly. When the clearance between the rail and the escaper is too
large, screws may fall down into the machine.
・
After making an adjustment, try making a vibration readjustment by referring
to " 5-4 Checking and Adjusting the Rail Vibration".
・
Check that the clearance between the rear hopper cover and the rail
assembly is about 0.2 mm.
・
If the rail hits against the rear hopper cover, the vibration will become weak
and the screws will be delivered slowly.
If the rear hopper cover is too high, the slit between the rail and the scraper
catches screws easily.
・
If adjustment is required, loosen the rear hopper cover attaching bolts and
make an adjustment either up or down.
