５．Pre-operating setup
5-1．How to install
1) Install at a position 200 to 250 mm higher than the
location where the screws are supplied and
be careful not to twist or forcibly bend
the feed hose.
2) Prepare a stand block for use during installation
and set so that the rubber feet of the feeder unit
are on the stand block.
Installing directly without using a stand block will
cause a drastic bend in the screw feed hose.
5-2．Installing the wiring and piping
Always connect to ground line. Failure to connect
to ground may cause elecrical shocks.
1) Connect the ground terminal on the rear panel to
ground by using a ground wire.
2) Then connect power supply cord to a powers supply.
3)Connect the air hose to the factory air source.
(or air compressor.)
The air hose fitting is the φ8
The source air pressure cannot be adjusted on this
unit,so adjust the factory source air pressure to a
range wihtin 0.4 to 0.5 MPa.
4) If using the air screwdriver,connect the air
screwdriver hose to the φ8 fitting
on the front panel of the feeder.
5) Connect the screw feed signal plug (from external
section) to the receptacle (3P) on the front panel of
the feeder.

5-3．Setup prior to installation work
① Setting the screw feed pressure
Open the factory air source (or air compressor) knob
and use the pressure-relief valve on the air unit to
adjust the pressure as needed while checking the
pressure gauge on the front panel.
Raising the air pressure higher than necessary will
damage the screw feed hose,or the solenoid valve.
Setting the pressure too low on the other hand will
cause poor screw feed. Normally use a pressure
within 0.15 to 0.25 MPa.
② Setting the screw feed timer
Set a suitable time on the front side of the screw
feed timer (FEEDTIMER), form feeding
the screw through the hose unitl reaching
the specified location.
See ② DATA LED MODES ”D”and”D.”on page 6 for
detailed information.
③ Adjust the empty screw warning time
A buzzer sounds and an error signal is sent when the
rotating drum has run longer than a preset time.
Note：The buzzer and error signal are optional features.

６．How to use
① Fill screws up to or below the referende line
in the hopper.
Refill after finished using up the last loaded screws.
Do not let malformed,different type screws or metal
scrap get mixed in with the screws you are loading.
Do not use screws that were picked up by magnets
or that are coated with oil.
② Turn on the power switch
The three digit LED lamp then light up
and the rotating drum starts turning.
Screws are then fed along the chute and the unit
rotates for a fixed quantity of screws. The rotating
drum automatically stops when the screws are
aligned and the motor lamp turns off.
Do not point the screw feed hose tip at other persons. The screws
may fly outwards creating a hazardous situation.
③
Send a screw feed signal from external source.
Sending a first signal causes the escapement to
move back and forth one time, sorts out one screw
on the chute,and sends it by compressed air
along the screw feed hose to a specified location.
Never point the tip of the screw feed hose
at someone since the screw may fly outwards
causing injuries or hazardous situations.
If using the VIS SETTER Handy as the screwdriver,
you can send a feed screw signal from the
screwdriver switch to the VIS SETTER by
retracting-extending the Y-pipe on the driver
one time by hand as shown in the figure.

７．Maintenance and storage
7-1．Maintenance after daily work
Always turn off the power switch before cleaning or
servicing the unit. Unplug the power cord from the outlet
(socket) if not planning to use it for a long time.
① Cleaning the chute
Use a brush or similar tool to clean dust or
metal powder that is sticking to the screw
sliding surfaces of the chute.
Gently wipe away oil using new cloth moistened with
alcohol.Take care not to scratch or dent the sliding
surfaces during cleaning.
② Supplying oil and draining water from
the filter
If using the VIS SETTER Handy as an air screwdriver,
loosen the needle valve on the oiler and check
from the droplet window that 3 to 5 drops of oil
fall while operating the air screwdriver under no load
(run with no load on the tip).
Then tighten the needle valve. Finally operate the air
screwdriver under no load for 1 to 2 minutes.
Loosen the drain cock and let water from inside
the tank drain off. Do not let water accumulate
above the upper limit line in the drain window.
7-2．Once a week maintenance
① Cleaning the inside of the hopper
Take out the screws from inside the hopper and
remove debris.
If extremely dirty or oil is adhering, wipe away gently
with a fresh cloth moistened with alcohol.
Do not use anything other than alcohol.
② Checking the oil level in the oiler.
If using the VIS SETTER Handy as an air screwdriver,
check whether the oil level in the oiler is within
the upper and lower limits. If the oil level is low,
shut off the air source (compressor, etc.),
remove the oil fill plug,and fill with oil.

secure the outer gear.
④ Adjusting the drive roller transmission force
Adjust the transmission force by the drive roller to
prevent the motor gear head from seizing up
when the rotating drum makes an emergency stop.
1)Remove the screws from inside the hopper and chute.
2)Turn on the power and after loosening the setscrew,
adjust the spring holder nut so that the roller shaft still
turns even if the rotating drum is stopped by hand.
Turn to the right to increase the transmission force
or turn to the left to reduce the transmission force.
⑤ Adjusting the optical axis of the optical switch
The optical sensor switch temporarily stops the drive
motor for the rotating drum in order to prevent
damage to the specified number of screws aligned
on the chute and to reduce power consumption.
However,if the optical axis deviates from the proper
position,this function is disabled, so adjust the optical
axis as follows:
1)Remove the screws from inside the hopper and chute.
2)Turn on the power and if the motor lamp lights up,
then the optical axis is in the roughly correct range.
3)Loosen the screw ① on the right side bracket,swing it
along the direction of arrow A and tighten the screw ①
at the middle position in the range where the motor
lamp lights up.
4)If just adjusting the right side bracket is insufficient, then also loosen the left side bracket,swing it
along the direction of arrow B and adjust the left and right brackets at the mid-position
where the motor lamp lights up.
5)If the adjustment is still unsatisfactory, then loosen the setscrew ③ for the optical sensor and
slide the optical sensor along the direction of arrow C, to adjust it to a mid-position where the
motor lamp lights up.

⑧ Adjusting the screw feed air flow rate
If operation is still unsatisfactory after adjusting the
screw feed air pressure and time, then try adjusting
the feed air flow rate. Adjust this by using the
switch rod adjuster screw on the left side of the
escapement of the feeder unit. To make the
screw feed speed faster, increase the air flow in the
screw feed hose by first loosening the nut and
then turning the switch rod adjuster screw
counterclockwise. To lower the screw feed speed
on the other hand , turn the adjuster screw clockwise
to lower the air intake flow. Setting too high an air flow
rate will speed up the screw feed speed but
also damage the screw feed hose's internal surfaces.
Use caution here because the screw feed will
also use more compressed air so that the escapement
Note：In the auto feeder unit, screws are operation will worsen somewhat.
pressured-fed from the hose fitting
air-blow unit (pressure feed block)
of the ES unit, so the switch rod
adjuster screw is tightened in the clockwise
direction.(see page 17 clause 8)
⑨ Changing the screw specifications
Screw specifications on the MK-3020 can be changed by
replacing the cartridge type escape attachment.
(You must also change the screwdriver if using the
VIS SETTER Handy as the screwdriver.) In that case,
consult your dealer for information.
1) Remove the screws from inside the hopper and chute.
2) Open the upper cover, pull the nylon latch on the
front cover and remove it.
3) Remove the left side cover.
4) Loosen impeller bolt ①, turn the bolt ② to the right,
and raise the impeller up all the way.
5) Loosen the impeller setscrews ① (two screws),
and pull off (remove) the raised impeller.
6) Pull off (remove) the gate.
