The maximum torque in the list is the set maximum torque that is generated by the tool itself in a selected operation mode.
The tightening torque obtained in an actual tightening operation varies with the screw or clamping member used.
Therefore, you need to try to tighten a few screws for confirmation.
*1: The Bolt mode 1, 2, and 3 are to be stopped by ten times of striking for accuracy improvement of tightening torque.
*2: Before fixing a thin plate with a self drilling screw, make sure that the thickness of the plate is suitable for the screw diameter.
*3: With the electronic clutch mode 4-10 the tool may execute reverse rotation briefly when the load increases in
order to reduce a risk of screw-head damage.
The tool starts up in low rotation speed and tightens softly.
The motor automatically stops rotating when the torque reaches to the pre-set value in order to reduce over tightening.
The clutch sound such as of the mechanical type will not be generated.
You can change the switchable operation modes with the dedicated software by connecting the communication
adaptor between the tool and PC.
2. Characteristics of Electronic Pulse Driver
Unlike a conventional impact driver, the electronic
pulse driver generates the striking force by rotating
the motor in regular and reverse directions repeatedly.
This mechanism has helped to provide quieter
operation.
The following characteristics are uncommon to a
conventional impact driver, however these are not
signs of malfunction.
The tool tends to be heated by continuous screw
tightening.
To protect the motor and electronic parts that control
the motor operation, this tool is equipped with a
temperature protection circuit.
Depending on the screw and material being screwed,
the striking operation may start early.
Since the striking operation causes temperature
increase of the motor and electronic parts, the
temperature protection circuit may be activated early.
Refer to "1. Continuous operation" on page 11 for
recovering from the operation stop caused by the
temperature protection circuit.

Also, the electronic pulse driver controls the motor
rotation consistently to provide the optimum
operation for each mode.
Because of this, the following cases can occur during
operation.
The behavior at operation start differs by the mode.
The self drilling screw mode (1) gradually increases
the speed.
The electronic clutch mode (regular rotation) rotates
the motor at a very slow speed for a certain period
after the start and then increases the speed.
On the other hand, the electronic clutch mode (reverse
rotation) meets the preset rotation speed immediately
after the start.
means default operation mode.
