• Fig 4](https://manuals.plus/wp-content/uploads/2024/02/HITACHI-NR83A-Round- Head-Framing-Nailer-Fig-4.png)

  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
     o The Nailer can be installed as follows:
     Remove the dust seal placed at the air inlet.
     Install a 3/8 NPT male plug at the air inlet. o A female coupler must be on the air hose.
     The hose coupling (male plug-female coupler) must remove all pressure from the Nailer when disconnected.
     Never use a non relieving coupler on the Nailer.

  5. Air consumption
     Using the Air consumption table and the Air compressor size formula. find a correct compressor size.

Air consumption table

psi Operating pressure (bar) (kgf/cm2)| 80  (5.5) (5.6)| 90 (6.2) (6.3)|  100 (6.9) (7)
---|---|---|---
Air consumption ft3 /cycle (It/cycle)| NR83A| .062(1.7)| .075 (2.1)| .088 (2.5)
NR83AA| .062 (1.7)| .075 (2.1)| .088 (2.5)

Air compressor size formula Amount of air required
=number of Nailers
X average nails driven each minute per Nailer
X air consumption at given air pressure
X safety factor (always 1 .2)
Example: 2 Nailers (NR83A) operating at 100 psi driving 30 nails per minute
Amount of air required
=2X30X .088(2.5)X 1.2
=6.3 CFM (ft3/min)(180 ltr/min)
After making the calculations as shown above, you should find a compressor providing 6.3 CFM of air that is required.

LUBRICATION
It is important that the Nailer be properly lubricated.
Without proper lubrication, the Nailer will not work properly and parts will wear prematurely.
o Use Hitachi pneumatic tool lubricant.
Do not use detergent oil or additives. These lubricants will harm the 0-rings and other rubber parts. This will cause the Nailer to malfunction.
o Filter-regulator-lubricator units should always be used.
Keep the lubricator filled with Hitachi pneumatic tool lubricant.
o If a lubricator is not available, supply 2 – 3 drops of Hitachi pneumatic tool lubricant into the air plug on the Nailer twice a day.

COLD WEATHER CARE
o Do not store the Nailer in a cold weather environment.
Keep the Nailer in a warm area until beginning the work.
o If the Nailer is already cold, bring it in a warm area and allow the Nailer to warm up before use.
(1) Reduce the air pressure to 40 psi (2.8 bar 2.8 kgf/cm2).
(2) Remove all nails from the Nailer.
(3) Connect the air hose and free-fire (blank-fire) the Nailer.
The lowered air pressure will be enough to free-fire the Nailer.
Slow speed operation tends to warm up the moving part.

CAUTION

• Do not free-fire the Nailer at high pressure.
