Example: 3 Nailers operating at 100 psi
driving 30 nails per minute
Amount of air required
= 3 × 30 × .018 (.5) × 1.2
= 1.9 CFM (ft
/min) (94 ltr/min)
3
After making the calculations as shown
above, you should fi nd a compressor
providing 1.9 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
always be used.
Keep the lubricator fi lled 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 64 psi (4.4
bar 4.5 kgf/cm
2 Remove all nails from the Nailer.
3 Connect the air hose and free-fi re
(blank-fi re) the Nailer.
The lowered air pressure will be enough
to free-fi re the Nailer.
Slow speed operation tends to warm
up the moving part.
CAUTION
●
Do not free-fi re the Nailer at high
pressure.

TESTING THE NAILER
●
Never use Nailer unless lock lever
is operating properly.
Before actually beginning the nailing work,
test the Nailer by using the checklist below.
Conduct the tests in the following order.
If abnormal operation occurs, stop using the
Nailer and contact a Hitachi authorized service
center immediately.
(1) Disconnect air hose from Nailer.
Remove all nails from Nailer.
□ All crews must be tightened.
If any screws are loose, tighten them.
□ The lock lever and trigger must move
smoothly.
