<Caution>
•
Using the screwdriver in the reverse rotation for longer than the time set in the Reverse
Counter Timer will be considered as a loosened screw, causing the count display to
count-up.
•
Be aware that releasing the start lever or repeatedly changing reverse rotation from ON
to OFF in order to loosen the screw within the time set by the Reverse Counter Timer
will not be calculated as a count-up.
•
Each previous count-down will be seen as one count-up operation.
•
Count-up will not proceed if no screws from the work set are tightened, but are loos-
ened.
* Note that, although the screw may not be loosened, count-up will occur if the
electric screwdriver is operated in reverse. This is because the torque-up signal
after completion of tightening with normal rotation does not exist in reverse rota-
tion.
