Lubrication; Cold Weather Care; Testing The Stapler - Hitachi n3804ab3 Instruction And Safety Manual

English
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 (N3804AB3 (S)) operating at 100
psi driving 30 staples per minute
Amount of air required
=3 × 30 × .025 (.73) × 1.2
=2.7 CFM (ft /min) (78.8 ltr/min)

After making the calculations as shown above, you
should fi nd a compressor providing 2.7 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 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 Stapler twice a day.

COLD WEATHER CARE

○ Do not store the Stapler in a cold weather
environment.
Keep the Stapler in a warm area until beginning the
work.
○ If the Stapler is already cold, bring it in a warm area
and allow the Stapler to warm up before use.
1 Reduce the air pressure to 40 psi (2.8 bar 2.8
kgf/cm ).
2
2 Remove all staples from the Stapler.
3 Connect the air hose and free-fi re (blank-fi re) the
Stapler.
The lowered air pressure will be enough to free-
fi re the Stapler.
Slow speed operation tends to warm up the
moving part.
CAUTION
● Do not free-fi re the Stapler at high pressure.

TESTING THE STAPLER

● Operators and others in work
area
glasses with side shields
which conforms to ANSI Z87.1
specifi cations.
Ordinary eyeglasses do not
●
provide adequate protection.
● Never use Stapler unless push lever is
operating properly.
Before actually beginning the stapling work, test the
Stapler by using the checklist below. Conduct the tests in
the following order.
If abnormal operation occurs, stop using the Stapler and
contact a Hitachi authorized service center immediately.
(1) DISCONNECT AIR HOSE FROM STAPLER.
REMOVE ALL STAPLES FROM STAPLER.
□ ALL SCREWS MUST BE TIGHTENED.
If any screws are loose, tighten them.
□ THE PUSH LEVER AND TRIGGER MUST MOVE
SMOOTHLY.
