Product Specific Safety Rules

WARNING
z Always use the electric screwdriver and controller as a set.
z
Using other power supplies could result in a fire or accident.
z Do not look directly into the LED (light-emitting part) from close up.
z
Powerful LED light could damage your eyes. Also, do not point the LED (light-emitting part) at people's or
animals' eyes.
CAUTION
z Since this machine uses the motor current to control the torque, individual differences in measurement joints,
z
or the measurement conditions, etc., may lead to fluctuation of the measured torque value. Measurement and
control of torque under the same measurement conditions is recommended.
z The output torque graph is standard.
z
The output torque range is not guaranteed. Make sure to measure torque.
z The speed set value is standard.
z
z The torque and speed may show individual differences.
z
Perform the settings and preliminary evaluation, and then use the specified electric screwdriver and controller
combination.
If changing the electric screwdriver and controller combination, again verify the settings and preliminary
evaluation before using the new combination.
z The torque or speed of the electric screwdriver will change over time. Inspect the torque or speed regularly and
z
conform to the value for your use.
By using the correct torque, the screwdriver will last longer.
z The speed or output torque changes based on the temperature of the main body.
z
z The effect of the bit part thrust and radial direction load on the motor may lead to fluctuation in the torque or
z
speed.
z Do not apply a shock (such as dropping) or excessive load to the button, switch, or signal terminal block.
z
Doing so could cause a failure.
z Do not apply refastening to a screw that has already been fastened (second tightening, check tightening). High
z
torque is impressed.
z For screw tightening, etc., of screws with short necks, or other screw fastening conditions where the screw is
z
quickly seated after the start, a high torque may be impressed. Perform preliminary evaluations, and then use
with caution.
z This tool is not an impact type electric screwdriver. Do not tighten twice (refastening). Also, it cannot be used
z
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.
z Do not use the tool for anything other than screw tightening.
z
It should not be used for tasks such as drilling or threading (such as a tapper).
z Connect the electric screwdriver and controller with a connection cord, and then insert the power source.
z
Note that disconnection of the connection cord during operations will result in an error.
z For the torque setting, use our Torque Checker and special screw joint. (p. 10)
z
z Use after performing adequate evaluation and verification beforehand to check that the various settings, screw
z
fastening speed, output torque, operability, and control systems, are suited to the usage environment.
z To ensure that there are no mistakes in operations channel switching, perform operations using full caution.
z
z Do not perform unnecessary operation of the electric screwdriver (spinning in idle, etc.).
z
This has an effect on the structural working life and motor heating.
