IMPORTANT SAFETY INSTRUCTIONS

INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS

• 
  General
  To reduce the risks of electric shock, fire, and injury to persons, READ ALL THE INSTRUCTIONS BEFORE USING TOOL.

1. OPERATORS AND OTHERS IN WORK AREA MUST WEAR EYE PROTECTION (SAFETY GLASSES WITH SIDE SHIELDS).
   When operating the Nailer, always wear safety glasses with side shields, and make sure others in work area wear safety glasses, too.
   Safety glasses must conform to the requirements of American National Standards Institute, ANSI Z87.1 and provide protection against flying particles both from the front and side.
   The employer must enforce the use of safety glasses by the Nailer operator and others in work area.
   
2. NEVER USE OXYGEN OR OTHER BOTTLED GASES. EXPLOSION MAY OCCUR.
   Never use oxygen, combustible gases or any other bottled gases as a power source for the Nailer.
   Use of the above gases is dangerous, as the Nailer will explode.
   Use only clean, dry, regulated compressed air.
   

3. NEVER POINT TOOL AT YOURSELF OR OTHERS IN WORK AREA.
   Always assume that the Nailer contains fasteners.
   Never point the Nailer toward yourself or others, whether it contains fasteners or not.
   If fasteners are mistakenly driven, it can lead to severe injuries.
   Never engage in horseplay with the Nailer.
   Respect the Nailer as a working implement.
   
4. DO NOT PLACE FINGER ON TRIGGER AND KEEP FINGER AWAY FROM THE TRIGGER WHEN NOT DRIVING FASTENERS TO AVOID ACCIDENTAL FIRING.
   Never carry the Nailer with finger on Trigger since you could drive a fastener unintentionally and injure yourself or someone else.
   Always carry the Nailer by the handle only.
5. CHOICE OF TRIGGERING METHOD IS IMPORTANT.
   Read and understand section titled "METHODS OF OPERATION."
6. DO NOT MAKE CONTACT WITH SAFETY TIP (PUSH LEVER) WHEN NOT DRIVING FASTENERS.

When using tools, basic precautions should always be followed, Including the following:

1. Work area
   1. 
      Keep the work area clean and well lighted. Cluttered benches and dark areas increase the risks of electric shock, fire, and injury to persons.
   2. Do not operate the Nailer in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. The Nailer is able to create sparks resulting in the ignition of the dust or fumes.
   3. Keep bystanders, children, and visitors away while operating the Nailer. Distractions are able to result in the loss of control of the Nailer.
2. Personal safety
   1. Stay alert. Watch what you are doing and use common sense when operating the Nailer. Do not use the Nailer while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating the Nailer increases the risk of injury to persons.
   2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair increases the risk of injury to persons as a result of being caught in moving parts.
   3. Avoid unintentional starting. Be sure the switch is off before connecting to the air supply. Do not carry the Nailer with your finger on the switch or connect the Nailer to the air supply with the switch on.
   4. 
      Disconnect the Nailer from the air source before making adjustments, doing Nailer maintenance, clearing jams, touching the Push Lever, when not in use, leaving work area, loading, or unloading the Nailer, handing it to another person. Never attempt to clear a jam or repair the Nailer unless you have disconnected air hose from the Nailer and removed all remaining fasteners from the Nailer. The Nailer should never be left unattended since people who are not familiar with the Nailer might handle it and injure the themselves. Such precautionary measures reduce the risk of injury to persons.
   5. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the Nailer in unexpected situations.
   6. Use safety equipment. A dust mask, non-skid safety shoes and a hard hat must be used for the applicable conditions.
   7. 
      Risk of hearing loss. Wear ear protection.
   8. Always wear head protection. Always wear head protection to protect your head from flying objects.
   9. Do not attach the hose or Nailer to your body. Attach the hose to the structure to reduce the risk of loss of balance if the hose shifts.
   10. 
       Place Nailer properly on workpiece. Do not fasten on top of another fastener. This is able to cause the fastener to be deflected and hit someone, or cause the Nailer to react and result in a risk of injury to persons.
3. Nailer use and care
   1. Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against the body is unstable and is able to lead to loss of control.
   2. Do not force the Nailer. Use the correct Nailer for the application. The correct Nailer will do the job better and safer at the rate for which the Nailer is designed.
   3. Do not use the Nailer if the switch does not turn the Nailer on or off. Any Nailer that cannot be controlled with the switch is dangerous and must be repaired. Never use Nailer which is defective or operating abnormally. If the Nailer appears to be operating unusually, making strange noises, or otherwise appears defective, stop using it immediately and arrange for repairs by a Hitachi authorized service center.
   4. Disconnect the Nailer from the air source before making any adjustments, changing accessories, or storing the Nailer. Such preventive safety measures reduce the risk of starting the Nailer unintentionally.
   5. Store the Nailer when it is idle out of reach of children and other untrained persons. A Nailer is dangerous in the hands of untrained users.
   6. Maintain the Nailer with care. Keep the Nailer Clean and lubricated for better and safer performance.
   7. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that affects the Nailer's operation. If damaged, have the Nailer serviced before using. Because of high air pressure in the Nailer, cracks in the surface are dangerous. To avoid this, do not drop the Nailer or strike the Nailer against hard surfaces; and do not scratch or engrave signs on the Nailer. Many accidents are caused by poorly maintained Nailers. There is a risk of bursting if the Nailer is damaged.
   8. Use only accessories that are identified by Hitachi for the specific Nailer. Use of an accessory not intended for use with the specific Nailer, increases the risk of injury to persons.
   9. Use only those fasteners listed in the Accessories section of this manual. Fasteners not identified for use with this Nailer by Hitachi are able to result in a risk of injury to persons or Nailer damage when used in this Nailer.
4. Service
   1. Tool service must be performed only by qualified repair personnel.
   2. When servicing a Nailer, use only identical replacement parts. Use only authorized parts.
   3. Use only the lubricants supplied with the Nailer or specified by Hitachi.
5. Air source
   1. Never connect to an air source that is capable of exceeding 200 psi (13.7 bar 14 kgf/cm²).
      Over pressurizing the Nailer is able to result in bursting, abnormal operation, breakage of the Nailer or serious injury to persons.
      DO NOT EXCEED 120 psi (8.3 bar 8.5 kgf/cm²).
      Use only clean, dry, regulated compressed air at the rated pressure or within the rated pressure range as marked on the Nailer.
      Always verify prior to using the Nailer that the air source has been adjusted to the rated air pressure or within the rated air-pressure range.
      
   2. Never use oxygen, carbon dioxide, combustible gases or any bottled gas as an air source for the Nailer. Such gases are capable of explosion and serious injury to persons.
6. Others
   1. Before starting work, check the nailing operation switching device.
      This Hitachi nailer includes a nailing operation switching device.
      Before starting work, check the setting of the operation switching device.
      If the switching device is not set properly, the nailer will not operate correctly.
   2. 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,
      • Intermittent operation (Trigger f ring)
        1. Set the switching device to SINGLE SEQUENTIAL ACTUATION MECHANISM.
        2. Pull the trigger rapidly and firmly.
      • Continuous operation (Push lever firing)
        1. Set the switching device to CONTACT ACTUATION MECHANISM.
        2. Do not press the nailer against the wood with excessive force.
        3. Separate the nailer from the wood as it recoils after nailing.
   3. Never Use NON relieving coupler on Nailer. If a non relieving coupler is used on the Nailer, the Nailer can remain charged with air after disconnecting and thus will be able to drive a fastener even after disconnecting. The Nailer and air hose must have a hose coupling such that all pressure is removed from the Nailer when the coupling joint is disconnected.
   4. Check Push Lever before use. Make sure the Push Lever operates properly. (The Push Lever may be called "Safety".) Never use the Nailer unless the Push Lever is operating properly, otherwise the Nailer could drive a fastener unexpectedly. Do not tamper with or remove the Push Lever, otherwise the Push Lever becomes inoperable.
   5. Keep all screws and covers tightly in place. Keep all screws and covers tightly mounted. Check their condition periodically. Never use the Nailer if parts are missing or damaged.
   6. Do not load fasteners with Trigger or Push Lever depressed. When loading fasteners into the Nailer or when connecting the air hose,
      1. do not depress the Trigger;
      2. do not depress the Push Lever; and
      3. keep the Nailer pointed downward.
   7. 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.
   8. 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.
   9. 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
   10. 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.
   11. Never carry Nailer by hose.
   12. Do not disconnect air hose from Nailer with finger on Trigger. The Nailer can fire when re-connected to An air supply.
   13. Handle Nailer correctly. Operate the Nailer according to this Manual. Never allow the Nailer to be operated by children, individuals unfamiliar with its operation or unauthorized personnel.
   14. Never use Nailer for applications other than those specified in this manual.
   15. Never modify or alter a Nailer. Doing so may cause it to malfunction and personal injuries may result.
   16. Be careful of the following when using blow nozzle.
       1. Do not touch the trigger.
       2. Do not point the air outlet at a person.
       3. Do not touch the push lever or set it to pushed up status.
          Flying nails can cause severe injury

BEFORE OPERATION

Read section titled "SAFETY".
Make sure of the followings before operation.

WORKING ENVIRONMENT

• No flammable gas, liquid or other flammable objects at worksite.
• Clear the area of children or unauthorized personnel.

AIR SUPPLY

• 
  NEVER use oxygen or other bottled gases. Explosion may occur.
  

• Never connect Nailer to pressure which potentially exceeds 200 psi (13.7 bar 14 kgf/cm²).
• Never use non relieving coupler on Nailer.

1. Power source
   • Use only clean, dry, regulated compressed air as a power source for this Nailer.
   • Air compressors used to supply compressed air to this Nailer must comply with the requirements of the latest version of ANSI Standard B 19.3 "Safety Standard For Compressors For Process Industries."
   • Moisture or oil in the air compressor may accelerate wear and corrosion in the Nailer.
     Drain daily.
2. Filter-Regulator-Lubricator
   • Use a regulator with a pressure range of 0 – 120 psi (0 – 8.3 bar 0 – 8.5 kgf/cm²).
   • Filter-regulator-lubricator units supply an optimum condition for the Nailer and extend the Nailer life. These units should always be used.

Filter
The filter removes moisture and dirt mixed in compressed air.
Drain daily unless fitted with an automatic drain.
Keep the filter clean by regular maintenance.

Regulator
The regulator controls the operating pressure for safe operation of the Nailer.
..Inspect the regulator before operation to be sure it operates properly.

Lubricator
The lubricator supplies an oil mist to the Nailer.
Inspect the lubricator before operation to be sure the supply of lubricant is adequate. Use Hitachi pneumatic tool lubricant.

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

Operating pressure	psi (bar) (kgf/cm2)	80 (5.5) (5.6)	90 (6.2) (6.3)	100 (6.9) (7)
Air consumption	ft3/cycle (ltr/cycle)	.038 (1.07)	.042 (1.18)	.045 (1.29)

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 (ft³/min) (139 ltr/min)

After making the calculations as shown above, you should find a compressor 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 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 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).
  2. Remove all nails from the Nailer.
  3. Connect the air hose and free-fire (blank-fire) the Nailer.
     The lowered air pressure will be enough to free-fire the Nailer.
     Slow speed operation tends to warm up the moving part.
• 
  Do not free-fire the Nailer at high pressure.

TESTING THE TOOL

• 
  Operators and others in work area MUST wear safety glasses with side shields which conforms to ANSI Z87.1 specifications.
  
• 
  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.
     
   • The push lever and trigger must move smoothly.
     
2. Adjust the air pressure to 70 psi (4.9 bar 5 kgf/cm²).
   Connect the air hose.
   Do not load any nails in the Nailer.
   Set the switching device to the upward position (SINGLE SEQUENTIAL ACTUATION MECHANISM).
   (Set the switching device to the upward position completely as shown in the diagram. Otherwise, it will not operate properly.)
   
   • The nailer must not leak air.
3. Remove the finger from the trigger and press the push lever against the wood.
   
   • The nailer must not operate.
4. Separate the push lever from the wood. Next, point the nailer downward, pull the trigger and then wait in that position for 5 seconds or longer.
   • The nailer must not operate.
5. 1. Without touching the trigger, depress the push lever against the workpiece. Pull the trigger.

This Hitachi nailer is equipped with a nailer operation switching device.
Use SINGLE SEQUENTIAL ACTUATION MECHANISM or CONTACT ACTUATION MECHANISM in accordance with the work to be performed.

Explanation of the various nailing operations

• SINGLE SEQUENTIAL ACTUATION MECHANISM: First, press the push lever against the wood; next, pull the trigger to drive the nail.
  After nailing once, nailing will not be possible again until the trigger is released and pressed again.
• CONTACT ACTUATION MECHANISM:
  First, press the push lever against the workpiece; next, pull the trigger to driver the nail. Or,
  pull the trigger; next, press the push lever against the workpiece to drive the nail.
  If the trigger is held back, a nail will be driven each time the push lever is pressed against the wood.

METHODS OF OPERATION

This Nailer 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 nails with this Nailer.

They are:

1. Intermittent operation (Trigger fire):
2. Continuous operation (Push lever fire):

1. Intermittent operation (Trigger fire)
   Use the SINGLE SEQUENTIAL ACTUATION MECHANISM setting.

• For intermittent operation, set the switching device to the upward position completely. (i.e. Set to SINGLE SEQUENTIAL ACTUATION MECHANISM.)
• To avoid double firing or accidental firing due to recoil.
  1. Set the switching device to SINGLE SEQUENTIAL ACTUATION MECHANISM.
  2. Pull the trigger rapidly and firmly.

1. Set the switching device to the upward position (to set to SINGLE SEQUENTIAL ACTUATION MECHANISM).
   (Set the switching device to the upward position completely as shown in the diagram. Otherwise, it will be set to CONTACT ACTUATION MECHANISM.)
   
2. Position the nail outlet on the workpiece with finger off the trigger.
3. Depress the push lever firmly until it is completely depressed.
   
4. Pull the trigger to drive a nail.
5. Remove finger from the trigger.

To continue nailing in a separate location, move the nailer along the wood, repeating steps - as required.

• 
  A nail will fire each time the trigger is depressed as long as the push lever remains depressed.

2. Continuous operation (Push lever fire)
   Using CONTACT ACTUATION MECHANISM

• 
  To avoid double firing or accidental firing due to recoil.
  1. Do not press the nailer against the wood with excessive force.
  2. Separate the nailer from the wood as it recoils after nailing.

1. Set the switching device to the downward position (to set to CONTACT ACTUATION MECHANISM).
2. (Set the switching device to the downward position completely as shown in the diagram. Otherwise, it will not operate properly.)
3. Pull the trigger with the Nailer off the workpiece.
4. Depress the push lever against the workpiece to drive a nail.
5. Move the Nailer along the workpiece with a bouncing motion.
   Each depression of the push lever will drive a nail.

As soon as the desired number of nails have been driven, remove finger from the trigger.

• Keep your finger off the trigger except during nailing 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. This Hitachi nailer may bounce from the recoil of driving a nail and unwanted subsequent nail may be driven, possibly causing injury.

The SINGLE SEQUENTIAL ACTUATION MECHANISM is for use where precision fastener placement is desired.

The SINGLE SEQUENTIAL ACTUATION MECHANISM may reduce the possibility of bodily injury to you or others in the work area compared to the CONTACT ACTUATION MECHANISM. This is because it is less likely to drive an unwanted nail if you keep the trigger pulled and accidentally bump the push lever against yourself or others.
The SINGLE SEQUENTIAL ACTUATION MECHANISM may also reduce the speed of operation compared to the CONTACT ACTUATION MECHANISM. The SINGLE SEQUENTIAL ACTUATION MECHANISM is recommended to inexperienced users.

NOTE

• If all warnings and instructions are followed, safe operation is possible with all two systems: SINGLE SEQUENTIAL ACTUATION MECHANISM and CONTACT ACTUATION MECHANISM.
• Always handle nails and package carefully. If nails are dropped, collating bond may be broken, which will cause mis-feeding and jamming.
• After nailing:
  1. disconnect air hose from the Nailer;
  2. remove all nails from the Nailer;
  3. supply 5 – 10 drops of Hitachi pneumatic tool lubricant into the air plug on the Nailer; and
  4. open the petcock on the air compressor tank to drain any moisture.

ADJUSTING THE NAILING DEPTH

• 
  When adjusting the Adjuster, be sure to remove your finger from the trigger and disconnect the air hose from the nailer.

To assure that each nail penetrates to the same depth, be sure that:

1. the air pressure to the Nailer remains constant (regulator is installed and working properly), and
2. the Nailer is always held firmly against the workpiece.

If nails are driven too deep or shallow into the workpiece, adjust the nailing in the following order.

1. DISCONNECT AIR HOSE FROM NAILER.
2. If nails are driven too deep, turn the adjuster to the shallow side.
   Adjustments are in half-turn increments.
   

If nails are driven too shallow, turn the adjuster to the deep side.

3. Stop turning the adjuster when a suitable position is reached for a nailing test.
4. Connect the air hose.
   ALWAYS WEAR SAFETY GLASSES.
   Perform a nailing test.
5. DISCONNECT AIR HOSE FROM NAILER.
6. Choose a suitable position for the adjuster.

USING THE BLOW NOZZLE

• Be sure to release your finger from the trigger before using the blow nozzle.
• Do not point the air outlet at a person.
• Do not use the blow nozzle with the push lever left fit.

This Nailer has a blow nozzle that blows out wood shavings which occur during work.
Press the knob with your thumb to use the blow nozzle, as shown in the figure.

NOTE

• When the blow nozzle is used for a long time, the nailing force may degrade temporarily. In this case, allows the air supply pressure to stabilize before starting work.
• Oil in the body or drained water from the compressor can sometimes spout out of the air outlet. It is recommended that you once conduct a test before use and see if such phenomenon happens at an environment where spouted oil will cause any inconvenience.

CHANGING THE EXHAUST DIRECTION
