    7-3. Related Laws and Regulations As nailers and staplers are designed to instantaneously drive nails and staples, there is an ever-present danger of misfiring and subsequent possible serious injury. Accordingly, close attention in handling is absolutely necessary at all times. Carefully ensure that the customer is fully aware of the precautions listed in the Instruction Manual provided with each unit.

    8. MECHANISM AND OPERATION PRINCIPLE 8-1. Mechanism As illustrated in Fig. 3, the Model N 5008AC can be generally divided into four sections: output section, control valve section, driving section and magazine section. The driving section (nose and piston) and the magazine section have been newly designed though its basic construction is the same as that of the Model NT 65A2 (valve section is common to the Model NT 65A2).

  • Page 14 Air pressure is applied in the shaded areas in the illustration, and each component is held in the position illustrated. If the operator's grip is loosened, air will leak. At there is no o-ring installed here, a very small amount of air will leak from the slight clearance between the components.
  • Page 15 The air pressure on the upper surface of the Exhaust Valve < 2 > is released, and the exhaust valve is pushed upward by the air pressure within the cylinder. This opens the Exhaust Vent < 3 >, and the air pressure in the cylinder is discharged from the nailer.
