Lubrication; Cold Weather Care; Testing The Nailer - Hitachi NT 65MA4 S Instrucciones Y Manual De Seguridad

English
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: 3 Nailers operating at 100 psi
driving 30 nails per minute
Amount of air required
= 3 × 30 × .045 (1.29) × 1.2
= 4.9 CFM (ft
After making the calculations as shown
above, you should fi nd a compressor
providing 4.9 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

● Operators and others
● Never use Nailer unless push lever
is operating properly.
Before actually beginning the nailing work,
test the Nailer by using the check list 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.
DANGER
in work area MUST
wear safety glasses
with side shields which
conforms to ANSI Z87.1
specifi cations.
Ordinary eyeglasses
do not provide
adequate protection.
