Hitachi N 5008AC manual Lubrication, Power source

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).

◯Filter-regulator-lubricator units supply an optimum condition for the Stapler and extend the Stapler life. 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 plug-female coupler) must remove all pressure from the Stapler when disconnected.

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	.028	.034	.040
	(ltr/cycle)	(.80)	(.95)	(1.14)

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 (N5008AC) operating at 100 psi driving 30 staples per minute

Amount of air required =3 ⋅ 30 ⋅ .040 (1.1) ⋅ 1.2

=4.3 CFM (ft3/min) (119 ltr/min)

After making the calculations as shown above, you should find a compressor providing 4.3 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 O-rings and other rubber parts. This will cause the Stapler to malfunction.

◯Filter-regulator-lubricator units should always be used. 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.
