General Safety Warnings
■General Safety Warnings
WARNING: Read all safety warnings and instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or
serious injury.
Save all warnings and instructions for future reference.
■Work area safety
-Keep work area clean and well lit. Cluttered or dark areas invite accidents.
-Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases
or dust. Power tools create sparks which may ignite the dust or fumes.
-Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
■Electrical safety
-Power tool plugs must match the outlet. Never modify the plug in any way. Unmodified plugs and
matching outlets will reduce risk of electric shock.
-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.
-Do not expose power tools to rain or wet conditions. Water entering a power tool/its adaptor will increase
the risk of electric shock.
-Do not abuse the cord. Never use the cord for carrying, 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.
-When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric shock.
-If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)
protected supply for its adaptor. Use of an RCD reduces the risk of electric shock.
■Personal safety
-Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a
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.
-Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
-Carrying power tools with your finger on the switch or energizing power tools that have the switch on
invites accidents.
-Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to
a rotating part of the power tool may result in personal injury.
-Do not overreach. Keep proper footing and balance at all times. This enables better control of the power
tool in unexpected situations.
-Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

General Safety Warnings
■ Use and Maintenance of power tool
- Please choose proper power tool according to the fastened object. Proper selected
power tool gets better efficiency.
- Do not use the power tool whenever power switch is faulty. Any power tool with faulty power switch is
dangerous and must be repaired.
- Before making any adjustment, replacing parts or putting away, please unplug the power tool to ensure the
safety and avoid unexpected start-up of power tool.
- Keep the idle power tool away from children, and prevent people who are not familiar with it from
operation. Power tool operated by untrained users is dangerous.
-The maintenance of power tool. Please check for all the possibilities that could affect the operation of
power tool. For example, uncalibrated power tool, movable parts are tied, damaged parts etc.
If any damage is found, repair it before use. Please also note improper repair can lead to an accident
easily.
- Keep the bits clean, and keep the bits with sharp edge, since it can get better control.

Read before use
Read before use:
■Please read the following notices before use:
‧Set-up Notice
-The controller should be used indoor and in dry place without the presence of dust and iron grindings.
-The controller should be positioned on a stable surface to avoid falling caused by vibration.
-The controller should be kept away from high voltage sources and noise generating sources to avoid
electromagnetic interference.
-No objects should be placed on the top of the controller. Keep its surrounding clear to allow heat
dissipation.
‧Caution during the operation:
-Please use the power supply with AC circuit which overload relay is included.
-The plug of the power cord is attached with ground pin, which must be connected to the socket equipped
with ground circuit to avoid electric shock.
-The plug of the power cord must be tightly plugged into the socket.
-For plugging and withdrawing the connecting cord between controller and screwdriver, please hold the
plug, do not pull the cable to avoid short circuit of the internal wires.
-It is directional when you plug the connecting cord into the driver and the controller’s socket. You have to
insert it in powerfully after aligning with covex point in the socket; then twist it to fix it on the driver or the
controller. Thus it will reduce the occurrence breakage of connecting cord due to drag. Use the knob to fix
the cable with the controller. Please see the picture below.
-Please do not suddenly switch between forward and reverse when the electric screwdriver is in operation.
-Please use the electric screwdriver with under 80% of the rated maximum torque to avoid inaccurate clutch
escape (The rated maximum torque may vary with the flexibility of the fastened object). If you need to use
over 80% of the rated maximum torque, please use the screwdriver with higher torque.

Product information
■Feature
-Universal power source: It is suitable for any power source ranges between 100-240VAC 50/60Hz.
-Stepless control: Output stepless control and constant voltage makes the assembly of light, thin, short, and
small works more efficient and they are key features electron industry pursues after. The smaller the
screw, the higher locking and tightening is required. With this function, it can satisfy the requirements of
high precision and low inertia in both long and short screws fastening.
-Soft start: There is 0-1 sec. soft-start function inside the power supply. The speed of fastening will
gradually change from slow to fast motion during the operation. This lowers the risk of screw shaking
when fastening.
- With output terminal for connecting to External controller for integrated control.
-Digital identified system: When power supply connects to screwdriver and power is On, it
will detect the type of screwdriver automatically.

Troubleshooting
■Troubleshooting
If the screwdriver does not work properly, follow the check-list below to examine your power supply. If
none of the scenarios can apply to the problem you encountered, do not open the power supply. Contact
your local sales agent immediately for further guidance.
‧The screwdriver is out of operation
-Please check the LED indicator on the power supply
-Please check whether the power plug is correctly and firmly plugged into the designated power source.
-Please check whether there is designated DC voltage between 5P-5P or 6P-6P terminal block needle NO:
1“-” potential, NO. 4“+” potential.
-Caution: If the screwdriver is 6-pin output in design, needle No. 3 and NO. 5 should be short-circuit first
to trigger the relay inside the screwdriver, and then you are able to measure the output voltage.
-Please check whether the connection cable plug of 5P-5P and 6P-6P was short-circuited. If yes, please
replace it with a new connection cable or a new plug. (This problem occurs more at the end of the plug
connecting to screwdriver.)
‧The screwdriver keeps rotating
-APM series: The power supply is designed with electric braking system. If you notice this problem,
please contact your sales agent.
‧The screwdriver did not stop automatically when the clutch shut off at preset torque (Except
reversed rotating)
-APM series: Turn the power supply off and make sure LED is off. Follow the instruction below and
connect the DC cable again.

Troubleshooting
DC cable is required to connect between
screwdriver and power supply. Please
kindly note the minimum bend radius(r)
of the cable is 60 mm.
While connecting DC cable
between screwdriver and
power supply (refer to
drawing below), please
align and match the covex
points inside the plug of DC
cable to the plugs on
screwdriver/ power supply,
and insert it properly. Then
rotate and tighten the nut in
clockwise direction.
Turn the power supply ON after
