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 not
responsible for any problems caused by using the product in a manner that does not conform to the contents
of this manual, using it improperly, or repairing / modifying by a third party except by us or someone specied
by us.

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 c ontaining 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 break er 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.

03

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.
