Dual Action Trigger - Hitachi NV 65AF3 Technical Data And Service Manual

6-4. Dual Action Trigger

The Model NV 65AF3 is equipped with a mechanism that allows switching the mode automatically between
"single sequential actuation" and "contact action" (see section 9 for the mechanism). Although S features a
similar automatic switching function, the mechanism is different from the Model NV 65AF3.

(2) Precautions for using dual action trigger
Nails are not driven even if the pushing lever is pushed against the workpiece again with the trigger pulled in
the single sequential actuation mode. To drive nails continuously, remove finger from the trigger and operate
according to the procedure of the contact action.
When the Model NV 65AF3 is raised from the floor (pushing lever was pushed against the floor) with the
trigger pulled, the Model NV 65AF3 turns into the single sequential actuation mode. Therefore, nails are not
driven even if the pushing lever is pushed against the workpiece. Release the trigger and operate according
to the procedure of the desired mode.
