Precautions on Using Nailer

1. Safe operation through correct usage
   This tool was designed for driving nails into wood and similar materials. Use it for its intended purpose only.

2. Make sure air pressure is within the rated range of air pressure.
   Please make sure that the air pressure is within a range of 4.9 bar – 8.3 bar (70 ~ 120 psi.), and that the air which is used is clean and dry. If the air pressure is greater than 8.3 bar (120 psi.), the life of the power tool will be shortened and dangerous conditions could develop. Tools shall not be connected to pressure which potentially exceeds 14 bar (200 psi.).

3. Never operate the equipment with high-pressure gases other than compressed air.
   Never use carbon dioxide, oxygen or another gas from pressurized containers under any circumstances.

4. Be careful of ignition and explosions.
   Since sparks may fly during nailing, it is dangerous to use this tool near lacquer, paint, benzine, thinner, gasoline, gas, adhesives and similar inflammable substances as they may ignite or explode. Under no circumstances should this tool therefore be used in the vicinity of such inflammable material.

5. Always wear eye protection (protective goggles). When operating the power tool, always wear eye protection, and ensure that surrounding people wear eye protection too.
   The possibility of fragments of the wire or plastic linking the nails or nails that were not properly hit entering the eye is a threat to sight. Eye protection can be bought at any hardware store. Always wear eye protection while operating this tool. Use either eye protection or a wide vision mask over prescription glasses.
   Employers should always enforce the use of eye protection equipment.

6. Protect your ears and head.
   When engaged in nailing work please wear ear mufflers and head protection. Also, depending on condition, ensure that surrounding people also wear ear mufflers and head protection.

7. Pay attention to those working close to you.
   It would be very dangerous if nails that were not properly driven in should hit other people. Therefore, always pay attention to the safety of the people around you when using this tool. Always make sure that nobody’s body, hands or feet are close to the nail outlet.

8. Never point the nail outlet towards people. Always assume the tool contains fasteners.
   If the nail outlet is pointed towards people, serious accidents may be caused if you mistakenly discharge the tool. When connecting and disconnecting the hose, during nail loading or similar operations, be sure the nail outlet is not pointed towards anyone (including yourself). Even when no nails are loaded at all, it is dangerous to discharge the tool while pointing it at someone, so never attempt to do so. No horseplay. Respect the tool as a working implement.

9. 9. Before using the power tool, check the push lever.
   Before using the power tool make sure to check that the push lever and valve operate properly. Without nails loaded into the power tool, connect the hose and check the following. If the sound of operation occurs this indicates a fault, so in such a case do not use the power tool until it has been inspected and repaired.

   • If merely pulling the trigger causes operating sound of drive bit movement occur, the power tool is faulty.
   • If merely pushing the push lever against the material to be nailed causes the sound of drive bit movement to occur, the power tool is faulty. Furthermore, with regard to the push lever, please note that it must never be modified or removed.

10. Use specified nails only.
    Never use nails other than those specified and described in these instructions.

11. Be careful when connecting the hose.
    When connecting the hose and loading nails in order not to fire the tool by mistake, make sure of the following.

    • Do not touch the trigger.
    • Do not allow the firing head to contact with any surface.
    • Keep the firing head down. Strictly observe the above instructions, and always make sure that no part of the body, hands or legs is ever in front of the nail outlet.

12. Do not carelessly place your finger on the trigger. Do not place your finger on the trigger except when actually nailing. If you carry this tool or hand it to someone while having your finger on the trigger, you may inadvertently discharge a nail and thus cause an accident.

13. Completely Close the nail guide and do not open it during operation.
    If nailing is attempted when the nail guide is open, nails will not be driven into the timber, and there is a risk of dangerous discharge.

14. Press the nail outlet firmly against the material to be nailed.
    When driving in nails, press the nail outlet firmly against the material to be nailed. If the outlet is not applied properly, the nails may rebound.

15. Keep hands and feet away from the firing head when using.
    It is very dangerous for a nail to hit the hands or feet by mistake.

16. Beware of the tool’s kickback
    Do not approach the top of the tool with your head etc. during operation. This is dangerous because the tool may recoil violently if the nail currently being driven in comes into contact with a previous nail or a knot in the wood.

17. Take care when nailing thin boards or the corners of wood.
    When nailing thin boards, the nails may pass right through, as may also be the case when nailing the corners of wood due to deviation of the nails. In such cases, always make sure that there is no one (and nobody’s hands or feet; etc.) behind the thin board or next to the wood you are going to nail.

18. Simultaneous nailing on both sides of the same wall is dangerous
    Under no circumstances should nailing be performed on both sides of a wall at the same time. This would be very dangerous since the nails might pass through the wall and thus cause injuries.
    Do not use the power tool on scaffoldings, ladders. The power tool shall not be used for specific application for example:

    • when changing one driving location to another involves the use of scaffoldings, stairs, ladders or ladder alike constructions, e.g. roof laths,
    • closing boxes or crates,
    • fitting transportation safety systems e.g. on vehicles and wagons

19. Do not disconnect the hose with your finger on the trigger.
    If you disconnect the hose with your finger on the trigger, the next time the hose is connected, there is a danger that the power tool will fire a nail spontaneously, or operate incorrectly.

20. Disconnect the hose and take out any nails left in the magazine after use.
    Disconnect tool from air before doing tool maintenance, cleaning a jammed fastener, leaving work area, moving tool to another location, or after use. It is very dangerous for a nail to be fired by mistake.

21. When removing a nail which has become stuck, make sure to first of all disconnect the hose and release compressed air.
    When removing a nail which has become stuck in the nail outlet, first of all make sure to disconnect the hose and release compressed air inside the power tool.
    Accidental firing of the nail could be very dangerous.

22. To avoid hazards caused by falling nails, never open the magazine with the device facing downward while loading nails.

23.  A female plug (air socket) should not be used in the body.
    If a female plug is installed in the body, the compressed air sometimes can not be drawn when the hose is disconnected so avoid this.
    The tool and air supply hose must have a hose coupling such that all pressure is removed from the tool when the coupling joint is disconnected.

24. Do not remove the dust cover
    Never operate with the dust cover removed in order to avoid the danger of breakage of the wire or plastic retaining the nails or missed-fired nails flying about.

• Recheck on operational safety.

BEFORE USE

1. Check the air pressure
   CAUTION:
   The air pressure must be constantly maintained at 4.9 – 8.3 bar (70 – 120 psi.).
   Adjust the air pressure between 4.9 to 8.3 bar (70 ~ 120 psi.) according to the diameters and length of nails and hardness of the wood being nailed. Pay special attention to the output pressure, capacity, and piping on the air compressor, so that air pressure does not exceed the specified limit. Note that excessive pressure may affect overall performance, service life, and safety.

2. Lubrication

3. Prior to operating this nailer, be sure to provide an air set between the air compressor and this device. Lubrication through the air set offers smooth operation, extended service life, and anticorrosion. Adjust the oiler so that a single drop of oil is supplied at intervals of 5 to 10 nailing cycles.

4. It is recommended using the recommended oil (SHELL TONNA). Other applicable oils are listed. Never mix two or more types of different oils.

5. Load nails

   • Press the magazine stopper and open the magazine cover.

   • Adjust the position of the nail holder according to the nail length.
     The nail will not feed smoothly if the nail holder is not correctly adjusted.

   • Turn the nail holder about 90 degrees counterclockwise.

   • Move the nail holder up and down to align the top of the nail holder with a mark on the holder shaft in accordance with the length of the nails being used.

   • Turn the nail holder 90 degrees clockwise until you hear “click”.

NOTE :
Before loading nails in the magazine, adjust the nail holder. If the magazine cover is forcibly closed without adjusting the nail holder correctly, the nail holder may be damaged.

  * Place the nail coil in the magazine. Insert the first nail into the magazine opening.
  * Close the magazine cover.
  * Grip the nail guide and knob with finger.  

Press the knob down and swing the nail guide open.

  * Uncoil enough nails to reach the driving hole.  

Insert the first nail into the driving hole and the second nail between the two pawls of the feeder.
Fit the nail heads in the guide slot.
NOTE :
Be careful not to deform the collated wires and not to disengage the nails with the guide surface. Otherwise, the nail guide will not close correctly.

  * Pulling the nails to the right, swing the nail guide closed. 
  * Lock the knob completely.

HOW TO USE THE NAILER

CAUTIONS:

• Never use the head or body of this device as a hammer.
• Take precautions to ensure the safety of persons in the vicinity during 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:
Intermittent operation (Trigger fire)
Continuous operation (Push lever fire)

1. Intermittent operation (Trigger fire)

   • Position the nail outlet on the workpiece with finger off the trigger.
   • Depress the push lever firmly until it is completely depressed.
   • Pull the trigger to drive a nail.
   • Remove finger from the trigger.
     To drive another nail, move the Nailer along the workpiece and repeat this procedure.

2. Continuous operation (Push lever fire)

   • Pull the trigger with the Nailer off the workpiece.
   • Depress the push lever against the workpiece to drive a nail.
   • 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.

CAUTION:
Exercise care when nailing corners of lumber. When continuous nailing corners of lumber, a nail may go astray or break through the corner.
NOTES :

• Precautions on no-load operation
  Sometimes nailing will continue after driving in all nails previously contained in the magazine.
  This is termed “no-load operation”. Such operation may deteriorate the bumper, magazine, and nail feeder.
  To avoid no-load operation, occasionally confirm the amount of remaining nails. On the other hand, all nails should be removed after using this nailer.

• After completing operation, put into the body about 2cc oil through the hose joint to protect the tool from rust.

• Under low temperature conditions, the machine sometimes does not operate correctly. Always operate the machine at the appropriate ambient temperature.

1. Adjusting the nail-driving depth
   CAUTIONS:
   When making adjustments, be sure remove your finger from the trigger. When making adjustments, be sure that the nail outlet is not facing downward and that body parts or other persons are not in the path of the nail outlet.
   Adjusting the adjuster
   Carry out test driving. If the nails are too deep, turn the adjuster to the shallow side ( mark).
   If the nail depth is too shallow, turn the adjuster to the deep side ( mark).
   Depth is changed 1 mm with each rotation of the adjuster.
   NOTES:

   • When adjusting the adjuster, it does not rotate more than 3 mm from the deepest point where a nail goes down. Do not rotate the adjuster by force beyond that point.
   • The nail-driving depth can also be adjusted by changing the air pressure used. Carry this out together with movement of the adjuster. Using a high air pressure that does not match the nail-driving resistance will shorten the life of this nailer.

2. Changing the exhaust direction
   The direction of the exhaust vent can be changed by turning the top cover.

3. Cutting off the sheet
   Tear off the output sheet in the direction of the arrow when using the sheet collated nails.

INSPECTION AND MAINTENANCE

CAUTION :
Be sure to disconnect the hose during cleaning jams, inspection, maintenance and cleaning.

1. Countermeasure for nail jamming

   • Remove the nail roll from the magazine, open the nail guide, insert a rod into the outlet and tap the rod with a hammer.
   • Remove the jammed nail with slotted screwdriver.
   • Cut off the defective part of the steel wire which links the nails with cutting nippers, correct the deformation, then load the nail roll in the magazine.
   • In case of frequent jams, consult the Authorized Service Center from which you bought this machine.

2. Check on mounting screws for each part
   At regular intervals check every part for loose mounting screws and whether or not there are any air leaks. Retighten any loose screws. Operating the equipment with loose screws untightened will incur a hazard.

3. Inspecting the push lever
   Check if the push lever can slide smoothly.
   Clean up the sliding area of the push lever and use the provided oil for lubrication from time to time. Lubrication enables smooth sliding and simultaneously serves to prevent the formation of rust.

4. Inspecting the feeders

   • Occasionally clean the knob sliding part and then apply the recommended oil.

   • Open the nail guide and remove dust, etc.
     Apply lubricant to the sliding groove of the feeder and shaft. Check the nail stopper (A) and nail stopper (B) slide smoothly by pushing them with your finger.

   • Also, apply the recommended oil to the feeding surface of the nose and nail guide after cleaning. This promotes smooth operation and retards corrosion.
     CAUTION:
     Check for smooth movement of the feeders and stoppers before use. If movement is uneven, nails could be fired at an irregular angle, presenting a hazard to the operator and others nearby.

5. Inspecting the magazine
   Clean the magazine. Remove dust of wooden chips which may have accumulated in the magazine.

6. Storing

   • When not in use for an extended period, apply a thin coat of the lubricant to the steel parts to avoid rust.

   • Do not store the Nailer in a cold weather environment.
     Keep the Nailer in a warm area.

   • When ot in use, the Nailer should be stored in a warm and dry place.
     Keep out of reach of children.

COMPRESSOR

CAUTION:
When the maximum, operating pressure of the air compressor exceeds 8.3 bar (120 psi.), be sure to provide a reducing valve between the air compressor and nailer. Then, adjust the air pressure within the operating range of 4.9 – 8.3 bar (70 – 120 psi.). If the air set is installed, lubrication is also possible, thus providing additional convenience.

OILER-FILTER-REDUCING VALVE (Air Set)

So that the equipment can be operated under an optimum condition to ensure extended service life, it is advisable to use an oiler filter reducing valve. Please limit the length of the hose between the unit and the air set to within 10m when using.
