ⅠAbout SF501/ SF502
Designed for speed, stability, and convenience.
Improving screw driving speed and work efficiency by integrating pneumatic/ electric screwdriver,
high-tech automatic feeder, and high precision jaw.
The jaw is customized by particular screw and working environment to provide a stable operation.
Standard pneumatic screwdriver; optional models by customer also available.

ⅡInstallment
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.
◆For pneumatic screwdriver only.
Connect delivery hose Connect air hose
Connect signal cable

◆For electric screwdriver only.
Connect delivery hose Connect wire of elec. screwdriver
1. Connect feeder unit to compressed air source (air pressure 4-5 kg/cm2.)
2. Adjust air pressure
Connect air source Adjust air pressure
4. Check screw delivery timer setting on the front of the feeder unit. Standard operation
setting is approximate 0.5
5. Connect power cord to a single-phase AC-220 wall outlet.
Check delivery timer Connect power cord

2. Tryout:
(1) Open the cover of machine then load some screws.
Load screw Max. volume
(2) Turn power switch on
Check whether the light of power and VFD is “ON”.
Turn power switch on
(3) Check whether feeding action is normal
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) Check the pneumatic screwdriver is normal.(For pneumatic screwdriver only)
(4-1) Check the electric screwdriver is normal. (For electric screwdriver only)
Push-start type:
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.
Lever-start type:
The driver should rotate after pressing lever. Check for any abnormal sounds during
rotation.
(5) Check whether torque setting of pneumatic (elec.)is proper or not.
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.
Please refer to page 14 ”Torque adjustment” for pneumatic screwdriver
Please refer to page 14”Torque adjustment” for electric screwdriver.
Make sure that the driver is vertical to the work surface and the delivery hose is free of twists
and bent.

3. Normal Operation
(1) After all preparatory steps have been competed, load mass screw into the hopper.
(2) Turn power switch on
Load mass screws 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) Then, repeat the steps to tighten subsequent screw.

4. After Operation:
(1) Lubrication(For pneumatic screwdriver only)
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.
Lubricate
(2)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) Check air unit：Check that oil level is between the top and bottom marks.
Supply oil if oil is running low.
(Only pneumatic screwdriver needs oil; elec. screwdriver didn’t need lubricate.)
Lubricate Supply oil

(3) Drain the water which is accumulated in filter..
(4) BIT Replacement(For pneumatic screwdriver only)
To release the nut，disassembly pipe cover, pipe spring, Y pipe.
Use a negative driver and push the ring forward. Keep pushing the ring forward and
pull the bit out. And, still keep pushing the ring forward and insert the new BIT.
Lubricate and assembly it.
