4. Adjusting the Nailing Depth
The nailing depth can be adjusted by simply turning the adjuster.
* Adjusting the adjuster (Fig. 3)
•
Conduct test punching. If the nail sinks too deep, turn the adjuster knob toward the Shallow position
(
mark). If the nail sinks too shallow, turn the adjuster knob toward the Deep position (
mark)
(see Figs. 3 and 4). The nail sink quantity is changed 1 mm per rotation of the adjuster knob.
•
Do not push up the pushing lever when turning the adjuster.
•
Set the lock lever to the "FREE" position when punching nails.
5. Dual Action Trigger
The Model NV 90HMC is equipped with an automatic mode switching mechanism that automatically
switches between "single sequential actuation mode" and "contact action mode".

(2) Precautions on using the dual action trigger
•
Nails are not punched even with the pushing lever again pressed against the workpiece and the trigger
pulled in single sequential actuation mode. To punch nails continuously, remove your finger from the
trigger and operate according to the contact action procedure.
•
Note that when you raise the Model NV 90HMC from the floor (after pressing the pushing lever against
the floor) with the trigger pulled, single sequential actuation mode is automatically selected. Therefore,
nails are not punched even when you press the pushing lever against the workpiece. Release the
trigger and operate according to the procedure of the desired mode.
