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).
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.

CAUTION
 The output torque is the value measured in combination with the output torque measurement device.
When the output torque is measured by some other measuring device or combination, the value may be
different.
 The output torque and torque that occurs in screws do not match.
Use a torque wrench to check the torque generated on screws.
