WARNING! Read all instructions Failure to follow all instructions listed below may result in electric shock fire and/or serious
injure. The term "power tool" in all of the warning listed below refer to your mains operated (corded) power tool or battery operated
(cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Electrical Safety
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive atmosphere, such as in the presence of flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust of fumes.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) Electrical Safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed
(grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Don’t expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord to carry, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use.
Use of cord suitable for outdoor use reduces the risk of electric shock.
3) Personal Safety
a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use power tool while you
are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may
result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your finger on
the switch or plugging in power tools that have the switch on invites accidents.
d) Remove any adjusting keys or wrench before turning the power tool on. A wrench or a key that is left attached to a rotating
part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jeweler. Keep your hair, clothing, and gloves away from moving parts. Loose
clothes, jeweler, or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and
properly used. Use of these devices can reduce dust related hazards.
4) Power tool Use and Care
a) Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use power tool if switch does not turn it on or off. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source before making any adjustments, changing accessories,
or storing the power tools.
Such preventive safety measures reduce the risk of starting the power tool accidentally.

Instruction：
SW1：Selects ON, counts screws number forward as 1-----2-----3------4------5-----------------1…
Selects Off, count down the screws number as 5-----4-----3-----2------1-------------------5…
SW2：Sensing Switch, select ON means Counter needs external sensing switch, MYPC40-500 must be in
accordance with the sensing switch mode to determine if electric screwdriver will work. Select OFF
means unnecessary for external switch, count number don’t have to consider external switch to
determine if it works.
Note ： SA settings will affect SW2 = ON, SW4 = OFF the SENSOR drive mode, please refer to the SA
setting for detail information.
SW3：The Count number Reset Mode, when counting screws number reach to the setting value, counter must be reset to default
value, if select ON which stands for manual reset, user must press "SELECT/CONFIRM" / external CONFIRM (CN11+CN14)
Key on the panel back the setting count number, otherwise Electric Screwdriver is unable to start under no confirming situation
on the device. Select OFF makes system automatically to recover from the setting count number.
SW4：Switching Mode：Select ON means the external SENSOR need to have two signals been sent to MYPC40-500 which stands
for the fastener on operational process need to go through the sensor on machine table to identify the fastener has been
removed from working table, and new fastener goes through another SENSOR for confirming the new fastener that has
reached the working table. Therefore two confirming signals allow S MYPC40-500 to start the Electric Screwdriver running.
Select OFF means only need one SENSOR to confirm the fastener that has been removed from this working table；this allows
Electric Screwdriver starts to work.
SW5：Auto-Learning Mode: The Counter counts screws number and sends OK & NG signals followed by Ht/ Lt settings. Thus,
Auto-Learning Mode experiences and memorizes screw fastening time from beginning to the end. To do so, simply user
switches this mode to ON, and then system will ask fastening position (SL), number of screws (SC) to be tightened, whether
needs time to be changed back to default or not (At), and OK LED keeps displaying time (Ot). Besides, user can add slow start
function (Rc) or select speed level (SP), if need.
SW6：Arrangement form：The memory can save five units number, user can push switch ON, the system will automatically arrange
five units, easy for user to make arrangement at work.
SW7：Reverse Resuming：User can turn on the reverse resuming switch to lose screws back. The system is able to count backward for
presetting quantity of screws to be fastened. If the reverse resuming switch is switched to off, the system is only to do
countdown for the last screw.
Note：Multiple cycles (SW6：ON)：
(1) rr =0
Whether Sr = Y or Sr = N, the reverse will both added to the U1.
(2) rr>0：
The screw list set with rr；the screwdriver well not reverses and will not add screws on the screw count.
At this point the user press CLEAR button or use CN13 to clear the count value to solve the problem and restart the
operation after the "new work.
If customers want to reverse all screws, please turn off the counter before start reverse.

＊If the screwdriver stop time is in dotted line. it is normal fastening. "OK" will be shown.
＊If the screwdriver stop time is before Lt or over Ht stop is before Ht or over Lt, it is "N.G.".
＊User can freely adjust Ht. However, if Ht and Lt is closer, it will request more precise.
＊If the user press the push button of the screwdriver after Ht and Lt setting, it is "N.G".
Ht/Lt mainly set up the period of time. If stop is within the set period, it means OK. In contrast, it
will be (NG), as stop before Lt or after Ht. and should reconfirm whether wrong screws is taken.
More precise requested means more correct Ht/Lt set-up should be. The Lt default value: 0.00,
but it can be increased or decreased in SELECT.
