GENERAL POWER TOOL SAFETY WARNINGS

WARNING

• Read all safety warnings and all instructions.
• Failure to follow the warnings and instructions may result in electric shock, fi re and/or serious injury.
• Save all warnings and instructions for future reference.
• The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1. Work area safety
2. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
3. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
4. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
5. Electrical safety
6. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodifi ed plugs and matching outlets will reduce risk of electric shock.
7. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
8. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
9. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
10. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
11. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
12. Personal safety
13. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the infl uence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
14. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
15. Prevent unintentional starting. Ensure the switch is in the off -position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your fi nger on the switch or energising power tools that have the switch on invites accidents.
16. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
17. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
18. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
19. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
20. Power tool use and care
21. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
22. Do not use the power tool if the switch does not turn it on and off . Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
23. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
24. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
25. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may aff ect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
26. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
27. Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations diff erent from those intended could result in a hazardous situation.
28. Battery tool use and care
29. Recharge only with the charger specifi ed by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fi re when used with another battery pack.
30. Use power tools only with specifi cally designated battery packs. Use of any other battery packs may create a risk of injury and fi re.
31. When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fi re.
32. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, fl ush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
33. Service
34. Have your power tool serviced by a qualifi ed repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

WARNING
To reduce the risk of injury, user must read instruction manual.

WARNING :
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.
  Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

• Close the magazine cover gently. Applying excessive force may result in deformation of the nail strip, preventing the magazine cover from closing.
• If the magazine cover is hard to close, check the groove of the magazine. Nails sometimes get into the groove. If this happens, tilt the power tool and remove the nails with a precision screwdriver or thin bar. In particular, if any nails get into the hole shown in the cross-section drawing, remove them through the window in the back of the magazine.
  The Nailer is now ready to operate.

Removing the nails:

1. Press the stop lever and pull out the magazine cover.
2. Remove the nails from the blade guide or magazine.

NOTE

• If the strip breaks inside the blade guide, nails may be left behind when the nails at the front are removed.
• Check carefully inside the blade guide, as it will be hard to see any nails that have been left behind there.
• If nails get jammed and cannot be removed, refer to the section “CLEARING A JAM.”

NAILER OPERATION
Read section titled “SAFETY” (pages 5 – 12).

DANGER

• Operators and others in work area MUST wear safety glasses with side shields which conforms to ANSI Z87.1 specifications.

WARNING

• NEVER point tool at yourself or others in work area.
• Keep fingers AWAY from trigger when not driving nails to avoid accidental fi ring.
• Do not use the electrical cord if damaged. Have it repaired immediately
• Choice of triggering method is important. Please read and understand “METHODS OF OPERATION” found below.
• Never place your face, hands or feet near firing head when using.
• Do not drive nails on top of other nails or with Nailer at too steep of an angle; nails can ricochet and hurt someone.
• Do not drive nails into thin boards or near corners and edges of workpiece. Nails can be driven through or away from workpiece and hit someone.
• Never drive nails from both sides of a wall at the same time. Nails can be driven into and through the wall and hit a person on the opposite side.
• Never use Nailer which is defective or operating abnormally.
• Do not use Nailer as hammer.
• Do not secure the push lever. Failure to observe this may result in injury.
• Remove all remaining fasteners and battery  from nailer when:
  1. doing maintenance and inspection;
  2. checking proper operation of push lever and trigger;
  3. attaching or removing the nose cap;
  4. cleaning a jam;
  5. it is not in use;
  6. leaving work area;
  7. moving it to another location; and
  8. handing it to another person.
• Remove battery from Nailer when:
  1. loading nails;
  2. turning the adjuster.

CAUTION: Use caution not to throw the push lever tip onto wood when the push lever cannot be pushed up.

NOTE

• Operation may become sluggish if used at low ambient temperatures. Move to a warm location and allow the power tool and battery to warm up before using.
• Do not use the power tool to nail fl ooring or fl oor materials. Accidentally standing on any nails that stick up may lead to injury.
• Nails may bend or cracks may appear in the material depending on the hardness, thickness or combination of materials. Fire a test nail before commencing full use.

METHODS OF OPERATION

1. Disconnecting the battery Disconnect the battery from the power tool to prevent unexpected operation.

2. Loading the nails
   Load pin nails of the appropriate size for the job into the magazine.

3. Attaching the nose cap
   Attach the nose cap as necessary.

4. Connecting the battery
   Push the battery into the power tool until it clicks into place.

5. Driving in nails

   • Make sure the discharge outlet is fi rmly placed against the place where the nail is to be discharged and pull the trigger.
   • If the nails are not driven in completely, press the head of the power tool down fi rmly when nailing.
   • To adjust the nailing depth, see the section “ADJUSTING THE NAILING DEPTH”. Nails will not be discharged until the push lever is pressed against the object to be nailed and the trigger is pulled. In other words, nails will not be discharged when only the trigger is pulled, or when only the push lever is pressed against the object to be nailed. This is to prevent the nails from being discharged when the trigger is accidentally pulled or when the push lever is accidentally placed against something.

6. Finishing work
   When work is finished, disconnect the battery and then remove all the nails.

ANTI BLANK FIRING MECHANISM
This nailer is equipped with an anti blank fi ring mechanism to prevent blank fi ring when the nails run out. The trigger will cease to operate when 20 or fewer nails remain. Approximately 20 nails will remain after fi ring the strip of nails, but replenishing the magazine with nails of the same length will enable nailing to be continued.

ADJUSTING THE NAILING DEPTH

Make sure that the trigger is turned off and the battery has been disconnected before adjusting the adjuster. The nailing depth can be adjusted by rotating the adjuster.

Fire a test nail and if it is driven in too deep, adjust the depth by rotating the adjuster toward the shallower ( mark). If the nail is not driven in deep enough, rotate the adjuster toward the deeper ( mark).

The adjuster modifi es the depth by 0.75 mm each time it is rotated.

USING THE BELT HOOK

WARNING
Make sure the battery removed when using the hook. Pay suffi cient attention so that the main equipment does not fall. If the toll falls, there is a risk of accident.

Hook can be installed on the left or right side.
