Measuring an actual operation (Self-diagnosis)
NOTICE:
This function is available by default. If you have disabled the Field Setting mode on the computer,
enable this function beforehand. Refer to the instruction manual of "Makita Industry Tool Settings" for how to
configure.
You can measure the torque level and operating time of an actual operation by operating the tool. Measured torque
level and time can be used for such as;
• Reproducing a torque control technic of a well-skilled worker and;
• A time reference for the setting of the shortest/longest workable time range.
Measuring the torque level and operating time
1. Press the setting button several times until "Ad." is displayed on the indicator.
2. Press and hold the setting button until the indicator shows "Ch".
3. Perform the operation that you want to measure the operating time.
• If you have configured the torque level, operate the tool until it stops in the Tightening Auto Stop mode.
• If you have not configured the torque level (Free mode), operate the tool as necessary.
4. Check the measured result. Press the setting button once to display the actual torque level, and press it one
more time to display the actual operating time.
Every time you press the setting button, the indicator shows "Ch", the number of actual torque level, and the
number of actual operating time in a cycle.
5. Press and hold the setting button to exit the Self-diagnosis.
NOTE: The Tightening Auto Stop mode works even in the Self-diagnosis. If you want to measure the torque level
without limitation, set the torque level "FF" (Free mode) and perform the procedures above.
NOTE: If "- -" is displayed on the indicator, the impact did not work or the torque level is higher than 40. If "-.-" is
displayed in the indicator, the operating time exceeded 9.9 seconds.
• In case the impact did not work: Remeasure the torque level with longer workable time.
• In case the torque level is higher than 40: The tool cannot measure the torque level. Use the tool with higher
torque range if available.
• In case the operating time exceeded 9.9 seconds, the workable time range is not available.

Diagnosis
The tool has stopped by the
setting of the longest workable
time range (3.5 sec.) before
it reaches the setting of the
Tightening Auto Stop mode
(torque level 23).
