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.

2. NEVER USE REACTIVE GASES OR OTHER

BOTTLED GASES. EXPLOSION MAY OCCUR. Never use reactive gases such as 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.

DISCHARGE. Never carry the Nailer with fi nger on Trigger since you could drive a fastener unintentionally and injure yourself or someone else. Always carry the Nailer by the handle only.

5. KNOW AND UNDERSTAND WHAT TRIGGER

SYSTEM YOU ARE USING. Read and understand section titled “METHODS OF OPERATION.” (pages 19 – 21)

FASTENERS. 000BookNR83A5USmetabo.indb4000BookNR83A5USmetabo.indb4 2018/05/2213:58:542018/05/2213:58:545 English SAFETY — Continued WARNING When using tools, basic precautions should always be followed, Including the following:

(1) Keep the work area clean and well lighted. Cluttered benches and dark areas increase the risks of electric shock, fi re, and injury to persons. (2) Do not operate the Nailer in explosive atmospheres, such as in the presence of fl ammable liquids, gases, or combustible 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.

(1) Stay alert. Focus on your work and use common sense when working with the Nailer. Do not use the Nailer while tired, after having consumed drugs or alcohol, or while under the infl uence of 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 fi nger 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, attaching or removing the nose cap, when not in use, leaving work area, leaving the Nailer outside of the operator's supervision or control, loading, or unloading the Nailer, handing it to another person, elevating, lowering or otherwise moving the Nailer to a new location. 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 hearing protection. Hearing protection shall have a Noise Reduction Rating (NRR) determined in accordance with US Environmental Protection Agency rules that is appropriate for noise exposure. (8) Always wear head protection. Always wear head protection to protect your head from fl ying 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) – Drive Nails into proper work surface only. Do not drive nail into other nails. This is able to cause the fastener to be defl ected 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 metabo HPT authorized service center. 000BookNR83A5USmetabo.indb5000BookNR83A5USmetabo.indb5 2018/05/2213:58:542018/05/2213:58:546 English (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 may aff ect 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) Do not use the Nailer that is not in proper working order. Tags and physical segregation shall be used for control. (9) Use only accessories that are identifi ed by metabo HPT for the specifi c Nailer. Use of an accessory not intended for use with the specifi c Nailer , increases the risk of injury to persons. (10) Use only those fasteners listed in the Accessories section of this manual. Fasteners not identifi ed for use with this Nailer by metabo HPT are able to result in a risk of injury to persons or Nailer damage when used in this Nailer.

(1) Tool service must be performed only by qualifi ed 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 specifi ed by metabo HPT.

(1) Never connect to an air source that is capable of exceeding 200 psi (13.7 bar 14 kgf/cm

) if a regulator fails. 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/cm

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 reactive gases such as 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.

(1) Before starting work, check the nailing operation switching device. This metabo HPT 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) Always select the switching device that is appropriate to the application and the training of the operator. (3) When switching between SINGLE SEQUENTIAL and CONTACT, disconnect the air hose and remove all nails. (4) When the hook is attached, operate only with

SINGLE SEQUENTIAL ACTUATION MECHANISM

and not with CONTACT ACTUATION MECHANISM. SAFETY — Continued WARNING 000BookNR83A5USmetabo.indb6000BookNR83A5USmetabo.indb6 2018/05/2213:58:542018/05/2213:58:547 English (5) Be careful of double fi re and being hit by the Nailer due to spring back (“recoil”). After driving a nail, the Nailer may recoil causing it to move away from the work surface. To reduce risk of injury always manage recoil by:

1) always maintaining control of the Nailer.

2) allowing recoil to move the Nailer away from work

3) not resisting recoil such that the Nailer will be

forced back into the work surface. In “CONTACT ACTUATION MECHANISM”, if push lever is allowed to re-contact work surface before the trigger is released, an unintended discharge of a nail will occur. In order to avoid this undesirable double fi re,

Intermittent operation (Trigger fi re)

Set the switching device to SINGLE SEQUENTIAL ACTUATION MECHANISM.

Pull the trigger rapidly and fi rmly.

Continuous operation (Push lever fi re)

Set the switching device to CONTACT ACTUATION MECHANISM.

Do not press the Nailer against the wood with excessive force.

Separate the Nailer from the wood as it recoils after nailing.

4) keeping face and body parts away from the Nailer.

(6) 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. (7) Check Push Lever before use. Make sure the Push Lever operates properly, and is not inoperable, disconnected, or altered. (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, or otherwise cause the Push Lever to become inoperable. (8) 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. (9) 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.

(10) Keep hands and body away from fi ring head during use. Never place your hands or feet closer than 8 inches (200 mm) from the fi ring head. A serious injury can result if the fasteners are defl ected by the workpiece, or are driven away from the point of entry. (11) When working close to an edge of a workpiece or at steep angles, or driving fasteners into thin workpiece use care to minimize chipping, splitting or splintering, or free fl ight, ricochet or piercing of fasteners, which may cause injury. (12) 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. (13) Use extra caution when driving the Nailer into existing walls or other blind areas to prevent contact with hidden objects or persons on other side (eg., wires, pipes). (14) Check for live wires. Avoid the risk of severe electrical shock by checking for live electrical wires that may be hidden by walls, fl oors or ceilings. Turn off the breaker switch to ensure there are no live wires. (15) Do not lift, pull or lower the Nailer by the hose. (16) Do not disconnect air hose from Nailer with fi nger on Trigger. The Nailer can fi re when re- connected to An air supply. (17) 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. (18) Never use Nailer for applications other than those specifi ed in this manual. (19) Never modify or alter a Nailer. Doing so may cause it to malfunction and personal injuries may result. (20) Disconnect the air hose when affi xing the hook. (21) Do not affi x the hook on high or unstable locations. Also, do not affi x it to the body, clothing, belt or other personal items.

The lubricator supplies an oil mist to the Nailer. Inspect the lubricator before operation to be sure the supply of lubricant is adequate. Use metabo HPT pneumatic tool lubricant. Nailer Side Filter Lubricator Compressor Side Regulator

Compressed air supply hoses shall have a minimum working pressure rating equal to or greater than the pressure from the power source if a regulator fails, or 150 psi (10.4 bar 10.6 kgf/cm

), whichever is greater.

Using the Air consumption table and the Air compressor size formula, fi nd a correct compressor size. Air consumption table Operating pressure psi (bar) (kgf/cm

(6.9) (7) Air consumption

(2.5) 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: 2 Nailers operating at 100 psi driving 30 nails per minute Amount of air required =2 × 30 × .088 (2.5) × 1.2 =6.3 CFM (ft

/min) (180 ltr/min) After making the calculations as shown above, you should fi nd a compressor providing 6.3 CFM of air that is 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 metabo HPT 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 fi lled with metabo HPT pneumatic tool lubricant.

If a lubricator is not available, supply 5 – 10 drops of metabo HPT pneumatic tool lubricant into the air plug on the Nailer twice a day.

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.

Reduce the air pressure to 64 psi (4.4 bar

Remove all nails from the Nailer.

Position of Change Rod

Previously pull the trigger WARNING

Keep your fi nger 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. This metabo HPT nailer may bounce from the recoil of driving a fastener and unwanted subsequent fastener may be driven, possibly causing injury.

Some types of loaded nails can spark out of the muzzle during a nail driving operation. Exercise caution! 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 two systems: SINGLE SEQUENTIAL ACTUATION MECHANISM and CONTACT ACTUATION MECHANISM.

Always handle nails and package carefully. If nails are dropped, collating plastic may be broken.

1) disconnect air hose from the Nailer;

2) remove all nails from the Nailer;

3) supply 5 – 10 drops of metabo HPT pneumatic

tool lubricant into the air plug on the Nailer; and

4) open the petcock on the air compressor tank to

ADJUSTING THE NAILING DEPTH

[Only NR83A5 (with depth adjustment)] WARNING

Disconnect the air hose from the nailer before turning the adjuster. 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 fi rmly against the workpiece.

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

If nails are driven too deep, turn the adjuster to the shallow side. Adjustments are in half-turn increments.

Too Deep Turn Adjuster Flush 000BookNR83A5USmetabo.indb21000BookNR83A5USmetabo.indb21 2018/05/2213:58:562018/05/2213:58:5622 English If nails are driven too shallow, turn the adjuster to the deep side. Turn Adjuster Flush
