NoticeImportant Safety Instructions
Please read this manual and the power supply unit manual carefully before use to ensure proper operation. In
addition, do not use the product in the way not described in this manual. Please note that we are notresponsible for any problems caused by using the product in a manner that does not conform to the contentsof this manual, using it improperly, or repairing / modifying by a third party except by us or someone specified
by us.

Installation

Handling◦Do not install the device at the places described
below. Otherwise, it may cause a fire or a failure.
・A place of high humidity or with a lot of dust
・A place where it becomes high temperatures
・A place of fire・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.

◦Do not wear clothes with flippers on the cuffs,
gloves, neckties etc. Otherwise, they may getcaught in the rotating screwdriver and cause an
injury or a failure.

Power Supply◦Be sure to install an earth leakage breaker and asafety breaker on the commercial power source
before using it.
◦Connect the earth wire to the earth wire terminalof the outlet. You may have an electric shock
without the earth wire connection in case of anelectric leakage.
◦Avoid the octopus foot wiring and use of an
extension cord. Otherwise, it may cause a fire or anelectric shock.
◦Do not connect anything other than specified tothe connection part of this device. Otherwise, it
may cause an electric shock or a failure.

◦Wear suitable clothing and protective eye-wear forwork. Cover long hair with a hat etc. so that you
can work safely.
◦Turn off power when you leave the workplace, or
when you attach / remove a bit / an optional item.
◦If static electricity is charged, you need toneutralize 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 breakregularly.
◦We recommend use of a balancer to prevent thedevice from falling and to protect cords / wires.
◦Hold the plug when you attach / remove thepower cord, screwdriver and so on.
◦Protect cords / wires by not giving damages tothem; not remodeling them; not pulling them; notbending them forcibly; etc. Also, do not place
heavy items on the power cord. Otherwise, it may
cause a fire or an electric shock.
◦If you detect an uneven rotation, strange noises,
overheating or activation of a breaker, etc., stopusing the device immediately and have it repaired.
03

However, note that the device may be overheateddepending on the frequency of the workpiece orscrew types. As a countermeasure, prepare sparescrewdrivers of the same model to extend the tacttime and use them alternately, or review theselection 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.

Maintenance and Inspections◦Turn off power and remove the power plug fromthe outlet when the device is not in use for a longtime.
◦Remove the accessories from the screwdriver andstore them in the package box when it is not in use
them for a long time.
◦Inspect the device regularly to confirm there are
no damages. If you use it with damages, it may
cause a fire or an electric shock.
◦When you clean the device, turn off the power andremove the power plug from the outlet.
Otherwise, it may cause a fire or an electric shock.

◦Remove the bit from the screwdriver when you are
not working.

◦Use dry cloth to wipe of dust or stains. The dust
may absorb moisture to allow current to flow,
causing a fire.

◦If you cannot attach / remove the bit in the way
described in this document, please make contact
with our service section.

◦Store the device in a place where the appropriate
temperatures and humidity are controlled.

◦Fix the workpiece with jig / clump while inworking.
◦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 thescrewdriver completely stops. Otherwise, it may
cause a failure.
◦Do not disassemble / remodel this device.
Otherwise, it may cause a failure.
◦High torque has a large recoil on the hand or arm.
Hold the driver firmly to avoid being swung
around.
◦Do not work with the attached anti-reaction stand or
handle removed. It may cause an accident or injury.
04◦Do not store the device in an unstable place or aplace with vibrations. Otherwise, it may cause afailure.
◦Keep the device out of reach of anyone but people
involved in the workpiece.
◦We recommend genuine HIOS parts for
replacement.

Setting the Torque
The torque can be adjusted by pushing the torque adjustment spring with pressure. If you turnthe torque adjustment nut clockwise, the torque becomes large, and you turn it
counterclockwise, it becomes small.

Caution“Output Torque Guide” and the torque adjustment scale should be considered as a guide; they
do not guarantee actual torques. Use the torque meter by HIOS to check the torque precisely.

This section describes how to set the pass / fail criteria. There are two ways of setting, directteaching and manual setting.

Setting by Direct Teaching
Direct teaching uses real screws and workpieces. It measures the pulses of motor rotation fromwhen the screwdriver starts turning to when it reaches the torque-up. The maximum and theminimum measurements of pulses are set as the thresholds for pass / fail. Considering themeasurement errors, you can set allowable ranges on thresholds.
Example: Minimum pulse = 100, Maximum pulse = 120, Allowable range = +/-10%
The number of pulses during teaching
Allowable range: +10%

Allowable range: -10%

Caution◦Do not use the conditions (i.e. screws, workpieces, etc.) for teaching different from those ofreal operation. Otherwise, it may cause larger errors.
◦Before teaching you need to define the home position by fastening a screw.
