17. KEEP HANDS AND FEET AWAY FROM FIRING HEAD DURING USE.
Never place your hands or feet closer than 8 inches (200 mm) from the firing head. A serious injury can result if the fasteners are deflected by the workpiece, or are driven away from the point of entry.
18. PLACE STAPLER PROPERLY ON WORKPIECE.
Do not drive fasteners on top of other fasteners or with the Stapler at too steep of an angle; the fasteners can ricochet and hurt someone.
19. BE CAREFUL OF DOUBLE FIRE DUE TO RECOIL.
If the push lever is unintentionally allowed to re- contact the workpiece following recoil, an unwanted fastener will be driven. In order to avoid this undesirable double fire, 1) do not push the Stapler on the workpiece with strong force; 2) take the Stapler completely away from the workpiece using recoil, and keep the push lever away from the workpiece until the next desirable shot; and 3) pull the trigger and release it QUICKLY when performing intermittent operation (trigger fire).
20. DO NOT DRIVE FASTENERS INTO THIN BOARDS OR NEAR CORNERS AND EDGES OF WORKPIECE.
The fasteners can be driven through or away from the workpiece and hit someone.
21. NEVER DRIVE FASTENERS FROM BOTH SIDES OF A WALL AT THE SAME TIME.
The fasteners can be driven into and through the wall and hit a person on the opposite side.
22. CHECK FOR LIVE WIRES.
Avoid the risk of severe electrical shock by checking for live electrical wires that may be hidden by walls, floors or ceilings. Turn off the breaker switch to ensure there are no live wires.
23. NEVER CARRY STAPLER BY HOSE.

Regulator Stapler Side Compressor Side Filter Lubricator3. Air hose
Air hose must have a minimum working pressure rating of 150 psi (10.4 bar 10.6 kgf/cm ^2 ) 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
| psi 80 90 100 | ||||
| Operating pressure (bar) (5.5) (6.2) (6.9) (kgf/cm ^2 ) (5.6) (6.3) (7) | ||||
| Air consumption | ft^3/cycle .02 (ltr/cycle) | .034 (.80) | .040(95) (1.14) | |
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 (N5008AC) operating at 100 psi driving 30 staples per minute
Amount of air required
=3 · 30 · .040 (1.1) · 1.2
=4.3 CFM (ft³/min) (119 ltr/min)
After making the calculations as shown above, you should find a compressor providing 4.3 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 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 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.
①Reduce the air pressure to 40 psi (2.8 bar 2.8 kgf/cm ^2 ).
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.
Slow speed operation tends to warm up the moving part.
⚠️ CAUTION
●Do not free-fire the Stapler at high pressure.

⚠ WARNING
- Keep your finger off the trigger except during fastening operation, because serious injury could result if the push lever accidentally contacts you or others in work area.
- 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.
●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 wnat 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:
●Both STANDARD CONTACT TRIP MECHANISM and OPTIONAL SEQUENTIAL TRIP MECHANISM are safe if used as described above and according to all warnings and instructions.
●Always handle staples and package carefully. If staples are dropped, collating bond may be broken.
●After stapling:
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 nail 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.
text_image
Push Lever Piece Screw ①④ Disconnect air hose②To adjust the driven-in depth of a staple, loosen the screw that secures a push lever piece.
