WARNING
⬤Never connect Stapler to pressure which potentially exceeds 200 psi (13.7 bar 14 kgf/cm2).
⬤Never use non relieving coupler on Stapler.
1.Power source
◯Use only clean, dry, regulated compressed air as a power source for this Stapler.
◯Air compressors used to supply compressed air to this Stapler must comply with the requirements of the latest version of ANSI Standard B 19.3 “Safety Standard For Compressors For Process Industries.”
◯Moisture or oil in the air compressor may accelerate wear and corrosion in the Stapler.
Drain daily.
2. Filter-Regulator-Lubricator
◯Use a regulator with a pressure range of 0 – 120 psi (0
– 8.3 bar 0 – 8.5 kgf/cm2).
◯
These units should always be used.
Filter ................. The filter removes moisture and dirt
mixed in compressed air. Drain daily unless fitted with an automatic drain.
Keep the filter clean by regular maintenance.
Regulator ......... The regulator controls the operating
pressure for safe operation of the Stapler.
Inspect the regulator before operation to be sure it operates properly.
Lubricator ........ The lubricator supplies an oil mist to
| the Stapler. |
| Inspect the lubricator before operation |
| to be sure the supply of lubricant is |
| adequate. |
| Use Hitachi pneumatic tool lubricant. |

3. Air hose
Air hose must have a minimum working pressure rating of 150 psi (10.4 bar 10.6 kgf/cm2) or 150% of the maximum pressure produced in the system, whichever is higher.
4. Hose coupling
◯The Stapler can be installed as follows: Remove the dust cap placed at the air inlet. Install a 3/8 NPT male plug at the air inlet.

◯A female coupler must be on the air hose.
The hose coupling (male
Stapler use a non relieving coupler on the Stapler.
5. Air consumption
Using the Air consumption table and the Air compressor size formula, find a correct compressor size.
Air consumption table
| psi | 80 | 90 | 100 | |
Operating pressure (bar) | (5.5) | (6.2) | (6.9) | ||
| (kgf/cm2) | (5.6) | (6.3) | (7) | |
Air consumption | ft3/cycle | .029 | .033 | .037 | |
(ltr/cycle) | (.82) | (.93) | (1.05) | ||

Air compressor size formula Amount of air required =number of Staplers
⋅average staples driven each minute per Stapler
⋅air consumption at given air pressure
⋅safety factor (always 1.2)
Example: 3 Staplers (N5024A) operating at 100 psi driving 30 staples per minute
Amount of air required =3 ⋅ 30 ⋅ .037 (1.05) ⋅ 1.2
=4.0 CFM (ft3/min) (113 ltr/min)
After making the calculations as shown above, you should find a compressor providing 4.0 CFM of air that is required.
LUBRICATION
It is important that the Stapler be properly lubricated. Without proper lubrication, the Stapler will not work properly and parts will wear prematurely.
◯Use Hitachi pneumatic tool lubricant.
Do not use detergent oil or additives. These lubricants will harm the
◯
Keep the lubricator filled with Hitachi pneumatic tool lubricant.
◯If a lubricator is not available, supply 5 – 10 drops of Hitachi pneumatic tool lubricant into the air plug on the Stapler twice a day.
