Important Safety Instructions
Installation
◦Do not install the device at the places described
below. Otherwise, it may cause a re or a failure.
・A place of high humidity or with a lot of dust
・A place where it becomes high temperatures
・A place of re
・A place of direct sunshine
・A place containing corrosive gas in the air
・Unstable place
◦Do not use the device where the ambient
temperatures are out of the range of 5 to 40 °C.
Power Supply
◦Be sure to install an earth leakage breaker and a
safety breaker on the commercial power source
before using it.
◦Connect the earth wire to the earth wire terminal
of the outlet. You may have an electric shock
without the earth wire connection in case of an
electric leakage.
◦Avoid the octopus foot wiring and use of an
extension cord. Otherwise, it may cause a re or an
electric shock.
◦Do not connect anything other than specied to
the connection part of this device. Otherwise, it
may cause an electric shock or a failure.
Handling
◦Do not wear clothes with ippers on the cus,
gloves, neckties etc. Otherwise, they may get
caught in the rotating screwdriver and cause an
injury or a failure.
◦Wear suitable clothing and protective eye-wear for
work. Cover long hair with a hat etc. so that you
can work safely.
◦Turn o power when you leave the workplace, or
when you attach / remove a bit / an optional item.
◦If static electricity is charged, you need to
neutralize it before use.
◦Avoid an unstable place or an unreasonable
posture for work. Otherwise, it may cause an
injury.
◦Long-time work or some types of work may cause
strain on your hands, neck, arms or waist, causing
an injury. Avoid long-time work and take a break
regularly.
◦We recommend use of a balancer to prevent the
device from falling and to protect cords / wires.
◦Hold the plug when you attach / remove the
power cord, screwdriver and so on.
◦Protect cords / wires by not giving damages to
them; not remodeling them; not pulling them; not
bending them forcibly; etc. Also, do not place
heavy items on the power cord. Otherwise, it may
cause a re or an electric shock.
◦If you detect an uneven rotation, strange noises,
overheating or activation of a breaker, etc., stop
using the device immediately and have it repaired.

04
However, note that the device may be overheated
depending on the frequency of the workpiece or
screw types. As a countermeasure, prepare spare
screwdrivers of the same model to extend the tact
time and use them alternately, or review the
selection of screwdriver models.
◦Do not overload the device so much that it cannot
clutch. Otherwise, it may cause a failure of the
motor.
◦Do not touch the screwdriver while it is rotating.
Otherwise, it may cause an injury or a failure.
◦Keep your hands and face away from the rotating
section while in use. Otherwise, it may cause an
injury.
◦Remove the bit from the screwdriver when you are
not working.
◦If you cannot attach / remove the bit in the way
described in this document, please make contact
with our service section.
◦Fix the workpiece with jig / clump while in
working.
◦Do not use the switch lever as a hanger. Otherwise,
it may cause an accident or an injury.
◦Do not give a strong impact or excessive force.
Otherwise, it may cause a failure.
◦Do not operate the screwdriver with wet or oiled
hands.
◦Do not operate the FOR / REV switch before the
screwdriver completely stops. Otherwise, it may
cause a failure.
◦Do not disassemble / remodel this device.
Otherwise, it may cause a failure.
Maintenance and Inspections
◦Turn o power and remove the power plug from
the outlet when the device is not in use for a long
time.
◦Remove the accessories from the screwdriver and
store them in the package box when it is not in use
them for a long time.
◦Inspect the device regularly to conrm there are
no damages. If you use it with damages, it may
cause a re or an electric shock.
◦When you clean the device, turn o the power and
remove the power plug from the outlet.
Otherwise, it may cause a re or an electric shock.
◦Use dry cloth to wipe of dust or stains. The dust
may absorb moisture to allow current to ow,
causing a re.
◦Store the device in a place where the appropriate
temperatures and humidity are controlled.
◦Do not store the device in an unstable place or a
place with vibrations. Otherwise, it may cause a
failure.
◦Keep the device out of reach of anyone but people
involved in the workpiece.
◦We recommend genuine HIOS parts for
replacement.

Setting the Pass / Fail Criteria
This section describes how to set the pass / fail criteria. There are two ways of setting, direct
teaching and manual setting.
Setting by Direct Teaching
Direct teaching uses real screws and workpieces. It measures the pulses of motor rotation from
when the screwdriver starts turning to when it reaches the torque-up. The maximum and the
minimum measurements of pulses are set as the thresholds for pass / fail. Considering the
measurement errors, you can set allowable ranges on thresholds.

Example: Minimum pulse = 100, Maximum pulse = 120, Allowable range = +/-10%
Caution
◦Do not use the conditions (i.e. screws, workpieces, etc.) for teaching different from those of
real operation. Otherwise, it may cause larger errors.
◦Before teaching you need to define the home position by fastening a screw.
