5. Air consumption

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

Air compressor size formula Amount of air required =number of Nailers

⋅average nails driven each minute per Nailer

⋅air consumption at given air pressure

⋅safety factor (always 1.2)

Example: 2 Nailers operating at 100 psi driving 30 nails per minute

Amount of air required =2 ⋅ 30 ⋅ .063 (1.8) ⋅ 1.2

=4.5 CFM (ft3/min) (180 ltr/min)

After making the calculations as shown above, you should find a compressor providing 4.5 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.

￿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 Nailer 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 Nailer twice a day.

COLD WEATHER CARE

￿Do not store the Nailer in a cold weather environment. Keep the Nailer in a warm area until beginning the work.

￿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 70 psi (4.9 bar 5 kgf/cm2).

2Remove all nails from the Nailer.

3Connect 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.

TESTING THE NAILER

DANGER

￿Operators and others in

work area MUST wear safety glasses with side shields which conforms to ANSI Z87.1 specifications.

WARNING

￿Never use Nailer unless push lever is operating properly.

￿Do not push tool forward when positioning the first nail in metal hole. If pushing forward, nail head will be damaged and broken, or will cause jamming.

This tool has a Sequential Trip Mechanism (Single Shot) for use when precision nail placement is necessary.

You must first depress the nail point where you want to drive a nail and then pull the trigger. After the nail is driven, completely release the trigger and lift the tool off the work surface.

This tool is not designed for contact trip operation (bounce fire), and not available for contact trip valve units. And this tool has a new push lever (safety) mechanism, this is a different push lever mechanism from another nailers.

The position of the push lever when the nail feeder is pulled back is shown as below.

At Non-Firing

Nose

Push Lever

When nails are loaded and the trigger is depressed, the push lever comes down and when the push lever touches the workpiece, a nails is driven.

At Firing

This tool is equipped with a lockout feature that prevents the tool from being activated when there are 5 or less nails in the magazine.
