5-3. Nail Driving Force
Fig. 2 shows by type of wood and nail the nailer output energy provided by the supply pressure and the nailing
energy required for driving the nail flush. Air pressure which exceeds the intersecting point between the nailer
output energy and the required nailing energy for driving the nail allows the nail to be fully driven.
For example, when driving a nail of 3.05 mm dia. x 45 mm length (0.120" x 1-3/4") into a workpiece of hemlock
with the Model NV 45AB2, a pressure of about 6.5 bar (6.6 kgf/cm
2
, 94 psi) allows the nailer to drive the nail flush
with the wood surface. A pressure beyond this value causes the nail head to be driven below the wood surface.
Fig. 2 should be used as reference only because those values vary depending on the type of wood, moisture
content, and grain of wood.

5-4. Optional Accessories
Sequential trip mechanism kit (Single shot) (Code No. 878226)
A sequential trip mechanism kit is provided as an optional accessory for the Model NV 45AB2. By using this
optional accessory, a nail is driven by pressing the pushing lever first against a workpiece and then pulling the
trigger (single-shot operation), and no nail is driven when pulling the trigger first and then pressing the pushing
lever against a workpiece. Please recommend the sequential trip mechanism kit to the customers who want to
use it. Salespersons must instruct the customers to read the Handling Instructions attached to the sequential trip
mechanism kit and also the Handling Instructions of the Model NV 45AB2 thoroughly for correct use.
