Staple Driving Force; Optional Accessories - Hitachi N 5024A Technical Data And Service Manual

5-3. Staple Driving Force

Figure 2 shows by type of wood and staples, the stapler output energy provided by the supply pressure and the
stapling energy required for driving the staple flush. Air pressure which exceeds the intersecting point between
the stapler output energy and the stapling energy required for driving the staple allows the staple to be fully
driven.
For example, when driving a staple of 50 mm length (2") into a workpiece of hemlock with the Model N 5024A, a
2
pressure of about 7.7 bar (7.8 kgf/cm , 111 psi) allows the stapler to drive the staple flush with the wood surface.
A pressure beyond this value causes the staple head to be driven below the wood surface. Figure 2 should be
used as reference data because those values vary depending on the type, moisture content, and grain of wood.

5-4. Optional Accessories

Sequential trip mechanism kit (Single shot) (Code No. 876762)
A sequential trip mechanism kit is provided as an optional accessory for the Model N 5024A. By using this
optional accessory, a staple is driven by pressing the pushing lever first against a workpiece and then pulling the
trigger (single-shot operation), and no staple 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 N 5024A thoroughly for correct use.
