3. Confirm the input power is correct.
4. Confirm the cylinder are positioned.
5. Confirm that all parts are securely locked
Confirm the working air pressure (at 5.5(±0.5)kg/cm2)。
VIII、Test run
1. Open the hopper and cover and load hopper with a small quantity of screw.
Load Screws
Max Volume
2. Turn power switch on and connect air source
3. check feeding action is correct
1. check if pushing board move repeat until screw full on chute, the pushing board will stop if screw level over
sensor.
2. check if screw on chute can move smoothly.
3. the cylinder of screwdriver will move quickly.
4. The screwdriver will activate after pressing lever. See Fig.1

12
5.the cylinder move forward after releasing lever (feeding) see Fig.2
6.The cylinder will retract after few seconds, the screwdriver is ready to work. See Fig.1
7.there is no screw for first using. Do step 4.5. then the screw feeder to BIT.

4.check if working correct:
◼check if screwdriver work correct after press lever, and no noise.
◼Check if delivery hose, cable is smooth or not.
5.Check torque setting is correct.
◼Use screwdriver to tighten first screw to make sure torque setting.
◼Adjust torque setting if torque range is not proper.

IX、Operating steps
1. The machine can work after test run.
2. Aim screw to screw hole vertical and press the lever.
3. Move the screwdriver upward after screwing to avoid jaw set impact to work-piece when during cylinder
movement.
4. Do step 2.3 to continue working after feeding next screw.

X、Adjustment and replacement
1. air volume adjustment：
If the screw can’t reach to screwdriver within feeding time, please adjust air volume by procedures as below.
a.Use wrench to release nut of escapement.
b. Then use wrench to adjust screw by procedures as below.
※Reduce air volume ：Turn clockwise
※Increase air volume：Turn counter-clockwise
c. Then assemble nut after adjusting.
Caution: The different length of delivery hose will need different air volume. The jaw
will be damaged easily if air volume is too strong. The proper volume just let
screw deliver to tip of screwdriver.
2. Adjustment of escapement speed：
If the shutter of escapement works badly, then need to adjust speed value by procedures as below.
a. Change shutter for rightward speed, adjust right valve
b. Change shutter for leftward speed, adjust left valve.
Use 5mm hex-wrench to
adjust
Use 10mm hex-wrench
to adjust
left valve
right valve

16
3. regulating plate adjustment：
If the regulate plate is too high or low, please adjust by 4 ㎜hex-wrench and 8mm wrench to adjust.
4.torque adjustment and BIT replacement
Please remove air source, turn off power of
screw feeder and electric screwdriver if need to
replace BIT or adjust torque setting.
XI、Troubleshooting
1. Screw can’t reach tip of screwdriver：
(1). The screw jammed or delivery hose disconnected.
*Check whether there is miscellaneous material and tube didn’t connect or not.
(2). The air volume is too weak to feed screw from screw feeder to screwdriver.
*Adjust air volume
(3). Regulation plate chocked.
*Please adjust regulation plate and clean screw on track then adjust regulation plate to
appropriate position.
(4). If feeding time is too short.
Adjust screw
Replace BIT
Torque adjust ring

17
*Please【refer to VI.】
(5) If screw can’t fed in normal condition.
* Make sure there are screws in hopper.；If yes, please press lever for 1 second then release.
2. Screw can’t fed through escapement：
◆Please turn off power and air.
(1). The escapement is jammed by material.
*Move the ring around and try to remove.
*If it isn’t useful. Please release screw to open ES. cover
by 3mm Hex-wrench then clean it.
Re-assembly after done well.
3. screw can’t go through delivery hose ：
(1). There is material stuck inside delivery hose。
➢Remove delivery hose from escapement then clean it.
(2). There is material stuck inside hose joint.
➢Press the jaw and remove it.
4. screw stuck on rail：
(1). The rail is dirty
*Please use cotton dip alcohol to clean.
(2). The regulation plate position is not appropriate or screw tolerance is too big.
* Check regulation plate location. If it suppressed the screw, please adjust regulation plate.
(3). The track deformed or damaged.
* If yes, please ship back to dealer or our company.
5.stripping ：
(1) Check if the screw aim to screw hole correctly.

(2) The torque setting of the screwdriver is too large to damage the
screw hole type.
➢Please adjust the screwdriver torque setting
(3) The BIT is bent and cannot be accurately aligned to the screw
position.
➢Check if the BIT is bent
➢Change BIT
(4) The BIT is worn after working period of time.
➢Check if the BIT is worn.
➢Change BIT
(5) The screw head is deformed and abnormal and the BIT can’t align to screw, causing for stripping issue.
(6) Check if the screws are normal. Change abnormal screws.
➢Check if the screws are normal. Change abnormal screw.
6. Electric screwdrivers breakdown：
➢If the Electric Screwdriver cannot rotate, check if the power line is normal.
➢Check if the screwdriver switch is correct or not.
7.screw didn’t attach on BIT ：
1. The timer setting is too short
➢The screw will not reach jaw or stuck inside
hose joint.
2. The cylinder speed is too fast, the screw can’t attach
on BIT
➢adjust speed control valve
3. The cylinder speed is too low.
➢The BIT can’t move screw forward.
