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. Air consumption
Using the Air consumption table and the Air compressor size formula, find a correct
compressor size.
Air consumption table
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 (N3804AB2) operating at 100 psi driving 30 staples per minute
Amount of air required
=3 ×30 ×.027 (.78) ×1.2
=3.0 CFM (ft3/min) (84 ltr/min)
After making the calculations as shown above, you should find a compressor providing
3.0 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.
䡬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.
䡬Filter-regulator-lubricator units should always be used.
Keep the lubricator filled with Hitachi pneumatic tool lubricant.
䡬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
䡬Do not store the Stapler in a cold weather environment.
Keep the Stapler in a warm area until beginning the work.
䡬If the Stapler is already cold, bring it in a warm area and allow the Stapler to warm up
before use.
1Reduce the air pressure to 40 psi (2.8 bar 2.8 kgf/cm2).
2Remove all staples from the Stapler.
3Connect the air hose and free-fire (blank-fire) the Stapler.
The lowered air pressure will be enough to free-fire the Stapler.

This Hitachi Stapler has a STANDARD CONTACT TRIP MECHANISM (Bounce File). An
OPTIONAL SEQUENTIAL TRIP MECHANISM kit (SINGLE SHOT) is available as order part
number 882332.
THE STANDARD CONTACT TRIP MECHANISM (Bounce Fire) is for use where rapid fastener
placement is desired and must be operated in accordance with the following “Methods of
Operation”.
METHODS OF OPERATION
This Stapler is equipped with the push lever and does not operate unless the push lever is
depressed (upward position).
There are two methods of operation to drive staples with this Stapler.
They are:
1. Intermittent operation (Trigger fire):
2. Continuous operation (Push lever fire):
(1) Intermittent operation (Trigger fire)
1Position the staple outlet on the
workpiece with finger off the trigger.

(2) Continuous operation (Push lever fire)
1Pull the trigger with the Stapler off the
workpiece.
2Depress the push lever against the
workpiece to drive a staple.
3Move the Stapler along the workpiece
with a bouncing motion.
Each depression of the push lever will
drive a staple.
As soon as the desired number of staples
have been driven, remove finger from the
trigger.
WARNING
䢇Keep your finger off the trigger except during fastening
operation, beacuse serious injury could result if the push lever
accidentally contacts you or others in work area.
䢇Keep hands and body away from the discharge area. The
Stapler with contact trip mechanism may bounce from the
recoil of driving a fastener and unwanted subsequent fastener
may be driven, possibly causing injury.
䢇Some types of loaded staples can spark out of the muzzle
during a nail driving operation. Exercise caution!
THE OPTIONAL SEQUENTIAL TRIP MECHANISM (SINGLE SHOT PARTS) is for use where
precision fastener placement is desired and must be operated in accordance with the
following “Method of Operation”.
You must first depress the push lever (upward position) where you want to drive a
staple and then pull the trigger. After the each staple is driven, completely release the
trigger and lift the tool off the work surface. An OPTIONAL SEQUENTIAL TRIP
MECHANISM may reduce the possibility of bodily injury to you or others in the work
area. This is because it is less likely to drive an unwanted staple if you keep the trigger
pulled and accidentally bump the push lever against yourself or others. An OPTIONAL
SEQUENTIAL TRIP MECHANISM may also reduce the speed of operation compared to
the standard contact trip mechanism.
NOTE:
䢇Both STANDARD CONTACT TRIP MECHANISM and OPTIONAL SEQUENTIAL TRIP
MECHANISM are safe if used as described above and accroding to all warnings and
instructions.
䢇Always handle staples and package carefully. If staples are dropped, collating bond
may be broken.

1) disconnect air hose from the Stapler;
2) remove all staples from the Stapler;
3) supply 5 –10 drops of Hitachi pneumatic tool lubricant into the air plug on the
Stapler; and
4) open the petcock on the air compressor tank to drain any moisture.
ADJUSTING THE STAPLING DEPTH
To assure that each staple penetrates to the same depth, be sure that:
1) the air pressure to the Stapler remains constant (regulator is installed and working
properly), and
2) the Stapler is always held firmly against the workpiece.
If staples are driven too deep or shallow into the workpiece, adjust the stapling in the
following order.
1DISCONNECT AIR HOSE FROM STAPLER.
2If staples are driven too deep, turn the
adjuster to the shallow side.
Adjustments are in half-turn increments.
3If staples are driven too shallow, turn the
adjuster to the deep side.
Stop turning the adjuster when a suitable
position is reached for a stapling test.
