Product Specific Safety Rules
WARNING
 This product is for domestic use.
This unit complies with the domestic safety standards only. The product cannot be used overseas.
 When using an extension cord, select the wire diameter according to the extended length.
If the power cord is too long or a thin cable is wound on a coil drum for a long length, voltage drop could be
caused. In such a case, the original product performance cannot be demonstrated.
Maximum extended cable length Wire diameter
(conductor nominal cross-sectional area)
10 m 1.25 mm2or more
20 m 2 mm2or more
30 m 3.5 mm2or more
 Do not use the product together with another electric tool.
CAUTION
 This tool is not an impact type electric screwdriver. Do not tighten twice (extra tightening). Also, it cannot be
used for screw tightening of such things as wood or drywall.
Depending on fastening conditions, screws may become loose.
Improper impacts could decrease product life or cause product failure.
 Do not use the tool for anything other than screw tightening.
It should not be used for tasks such as drilling or threading (such as a tapper).
 Install the power cord and signal line separated from each other.
If AC line noise directly propagates to the signal line, poor contact of ASLINK may occur. If the product is used as
in the shipped status (1 m portion is in a collected state), it is no problem.
About Unit Notation
This instruction manual is written using both SI units and the imperial measurement method (yards, pounds).
Numeric values outside the ( ) are the value in SI units, while those inside the ( ) are the imperial measurement
value.

6 Basic Operation
Start
WARNING
 Properly connect the power plug.
 Always make sure the tool is grounded.
No grounding the tool could cause failure or electric shock at the time of electrical leakage.
If you are not sure about the grounding of the outlet, request an electrical contractor to check if it is grounded.
When an extension cord is used, use a 3-core cord that includes a ground wire.
1 Insert the power plug into an outlet (230 V AC)
Changeover switch
CAUTION
 Do not operate the changeover switch while the tool is rotating. Doing so could cause a failure.
 When the tool is not used, set the switch to neutral position.
 Do not apply a shock (such as dropping) or excessive load to the changeover switch. Doing so could cause a
failure.
By sliding the changeover switch, you can change the rotation direction of the electric screwdriver.
“ - ” means neutral. The electric screwdriver does not rotate.

The bit rotates when the electric screwdriver is pushed
in the bit direction.
Releasing it stops rotation.
The push start type has a start switch inside the electric
screwdriver.
Screw tightening
WARNING
 Firmly hold the main body to avoid losing your grip.
CAUTION
 Properly apply the bit end to the screw head.
 Check that the bit is not worn.
1 Slide the changeover switch to the “R” side
2 Apply the bit end to the screw head and press the start switch
3 When the electric driver stops, release the start switch

 Before adjusting the output torque, always turn OFF the power.
CAUTION
 The torque scale is a standard. The output torque range is not guaranteed.

7 Appendix
Troubleshooting
Symptoms Location to investigate Solution
The electric screwdriver
does not operate
Is the power plug inserted into an
outlet?
Is power supplied to the outlet?
Properly insert the power plug into the outlet.
Check the power supply.
Is the changeover switch set to
neutral? Slide the changeover switch to the R or L side.
The output torque is low
Screws cannot be
tightened
Are you using a combination of
NITTO KOHKI measuring devices for
measurement?
Use a combination of NITTO KOHKI's measuring
devices for measurement. (p. 4)
Are you turning the torque adjustment
ring clockwise?
Has the output torque dropped?
The output torque decreases as the tool is used.
Turn the torque adjustment ring clockwise. (p. 14)
Did you check the correlation between
the output torque occurred on screws
and the output torque measured using
a measurement device?
The output torque occurred on screws and the
output torque measured by the measurement device
are different.
Adjust the output torque according to the screw
fastening conditions. (p. 4)
Is the bit worn out?
When the bit is worn out, it becomes difficult to
transmit torque to screws.
Replace the bit. (p. 7)
Are you tightening while crushing a
part between the screws.
Has regression loosening occurred?
Torque may not be transmitted. Crush the part once
and then tighten the screw.
Has axial force occurred to the screw?
Without axial force, even though the output torque
is increased, screws are not tightened. Review the
screw fastening conditions.
Also, by tightening at low speed, it becomes easier
to transmit torque.
Has initial loosening occurred?
Initial loosening occurs as a result of permanent set
in fatigue when fine irregularities such as surface
roughness are lost over time after the screw is
tightened or outside force is applied. Tighten the
screw again.
Has the permanent set in fatigue
occurred due to permanent
deformation of sealing material such
as the gasket?
Carefully check the screw fastening conditions and
set the output torque.
Depending on the material, torque may not be
transmitted.
Is the area surrounding the screw at a
high temperature?
Screws could be extended or loosened by
temperature changes.
Review the screw fastening conditions and process.
Have you considered the occurrence
of vibration or outside force?
Loosening of screw occurs if no measures are taken
for vibration or outside force.
Take appropriate loosening prevention measures.
The output torque is high
Screws are tightened
too much
Did you check the correlation between
the output torque occurred on screws
and the output torque measured using
a measurement device?
The output torque occurred on screws and the
output torque measured by the measurement device
are different.
Adjust the output torque according to the screw
fastening conditions. (p. 4)
Have you attached a heavy jig or a jig
having a large radius at the end?
After the torque reaches the set torque, the inertial
force of the jig might have been transmitted to
screws.
Review the jig and reduce the weight or size of the
jig.
The torque scale and
output torque do not
match
The torque scale is a standard. The output torque range is not guaranteed.
The output torque range sometimes differs from the scale but this is not a product error.

Symptoms Location to investigate Solution
The electric screwdriver
gets hot
Is the ON time of the electric
screwdriver too long?
Alternatively, is the OFF time too
short?
Review the operation time.
The rated operating time is 0.5 sec. ON and 3.5 sec.
OFF.
Aim at 15 screws per minute. (p. 4)
Is the input voltage 230 V AC? Check the input voltage.
Even though the output torque is set
to the specification lower limit value,
does the screwdriver get hot to a level
where you cannot touch it?
When the output torque becomes higher, the electric
screwdriver becomes hot.
If it gets hot to a level where you cannot touch even
with the specification lower limit value, a failure is
suspected.
The rotation speed is not
stabilized.
Is the electric screwdriver heating up?
Is it the same electric screwdriver?
The specification value of the rotation speed is a
