II. Installment
1. Preparation
1. Connect the screw delivery hose, air hose and signal cable to the feeder unit
Take a balance of the driver unit for easier fastening. While taking balance, make sure that the signal cable and
air hose do not contact with hook or balancer wire. Care should be taken to prevent excessive bending or
twisting of hoses and cables, since this can cause damage or disconnection.
Connect the screw delivery hose between the feeder and the driver as soon as possible. Make sure that it is not
excessively bent or twisted after installation.

3. Since this unit has no provisions for adjusting air pressure, pressure must be controlled at the
source. ( PULLUPFIRST,AND ROTATE )

4. Screw delivery timer check.
Check screw delivery timer setting on the front of the feeder unit.
Standard operation setting is between 0 to1.
5. Connect power cord to a single-phaseAC-220 wall outlet.

2. Tryout
1. Open the hopper and cover and load hopper with a small quantity of screw.
Load Screws Max Volume
2. Turn power switch on.
The power and motor pilot lamps will light, the feeding track will start reciprocating and screw will
be fed into the chute. Once the chute is filled, the rotary drum automatically stops and the motor
pilot lamp will go off.
Turn Power Switch
3. While holding the driver unit, telescope the Y-pipe manually.
One cycle will send a signal to the feeder from the driver unit and the escapement will release one
screw from the chute for delivery to the driver’s tip by compressed air. First cycle has a 3~5
seconds delay of feeding.
Never point the driver tip toward a person since a screw might shot out accidentally, causing
possible injury.

4. Confirmation of driver bit rotation.
The driver should rotate when the bit is pressed against a flat surface while the Y-pipe is
compressed. Check for any abnormal sounds during rotation.
The driver rotates clockwise only.
Check Screw Feeding Check Rotating
5. Tighten torque check
Fit the driver tip over the hole of screw to be tightened a perform test fastening.
The screw is driven into the hole when the driver bit is pressed against the screw.
Check that the screw is fastened to the specified torque.
If not, adjust fastening torque. (See item 8 “Tightening torque adjustment” on page 14 for
adjustment).
Make sure that the driver is vertical to the work surface and the delivery hose is free of twists
and bent.
Lift the driver only after the whirring noise indicating clutch release is heard.
After completing installation and test operation, switch power off once before beginning normal
operation.

3. Normal Operation
1. After all preparatory steps have been competed, load screw into the hopper.
2. Turn power switch on.
1. Load Screws 2. Turn Power Switch
3. Hold the driver unit and press the Y-pipe manually to confirm that a screw is seen at the tip of the
driver at the first time.
4. Align the screw at the driver tip vertically with the screw hole of the work-piece.
5. When the driver bit is pressed against the screw, the screw will be tightened.
6. Then, repeat steps 4 and 5 to tighten subsequent screw.

4. After Operation
1. Lubrication
Loosen the needle valve of the oiler while idling the driver.After confirming oil flow of 3 to 5 drops
through the window, retighten the needle valve. Then, idle the driver unit alone for one or two
minutes to allow oil to circulate.
2. Chute cleaning
With a brush, remove dust and metal fragments from sliding surface of chute. Remove any grease
with a cloth soaked in alcohol.
Be sure power switch is turned off. Do not scratch or bruise the chute-sliding surface during
cleaning.
3. Power
Turn power switch off after completing operations.
5. Maintenance
1. Cleaning hopper interior
Clean the hopper interior once a week. Remove any remaining screw and dust. If the interior is
extremely dirty, wipe thoroughly with a clean
2. Oiler oil level check
Check that oil level is between the top and bottom marks.
Supply oil if oil is running low.
