Product Specific Safety Rules

WARNING
 Always use the electric screwdriver and controller as a set. 
Using other power supplies could result in a fire or accident.
 Do not look directly into the LED (light-emitting part) from close up. 
Powerful LED light could damage your eyes. Also, do not point the LED (light-emitting part) at people's or
animals' eyes.
CAUTION
 Since this tool uses the motor current to control the torque, individual differences in measurement joints or the 
measurement conditions, etc. may lead to fluctuations in the measured torque value. Measurement and control
of torque under the same measurement conditions is recommended.
 The output torque graph is for reference.

The output torque range is not guaranteed. Always measure the torque.
 The speed setting value is for reference. 
 The torque and speed may show individual differences. 
Perform the settings and preliminary evaluation and then use the specified electric screwdriver and controller
combination.
If changing the electric screwdriver and controller combination, before using the new combination, verify the
settings and preliminary evaluation again.
 The torque or speed of the electric screwdriver will change over time. Inspect the torque or speed regularly and

conform to the value for your use.
By using the correct torque, the electric screwdriver will last longer.
 The speed or output torque changes based on the temperature of the main unit. 
 The effect of the bit part thrust and radial direction load on the motor may lead to fluctuations in the torque or 
speed.
 Do not apply a shock (such as dropping) or excessive load to the button, switch, or external signal connector. 
Doing so could cause a failure.
 Do not attempt to perform refastening on a screw that has already been fastened (second fastening, check 
fastening). High torque is applied.
 For screw fastening of screws with short necks, or other screw fastening conditions where the screw is quickly 
seated after the start, high torque may be applied.
Perform preliminary evaluations, and then use with caution.
 This tool is not an impact type electric screwdriver. Do not fasten twice (refastening). Also, it cannot be used 
for screw fastening into a material such as wood or drywall.
Depending on the 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 fastening. 
It should not be used for tasks such as drilling or threading (such as a tapper).
 Connect a connection cord to the electric screwdriver and controller and then provide a power source. 
Note that disconnecting the connection cord during operation will result in an error.
 For the torque setting, use our Torque Checker and special measuring joint. (p. 64) 
 Use this tool after performing adequate evaluation and verification beforehand to check that the various 
settings, screw fastening speed, output torque, operability, and control systems are suited to the usage
environment.
 To ensure that there are no mistakes in operation channel switching, use full caution when performing 
operations.
 Do not perform unnecessary operation of the electric screwdriver (spinning in idle, etc.).

This has an effect on the service life of the mechanical part and motor heating.
 If you use the push start type with the automatic machine, make sure to push completely and then start the 
tool.
