8. Do not rush the job or force the tool. Handle the tool carefully.
9. Watch your footing and maintain your balance with the tool. Make sure there is no one below when working in high locations, and secure the air hose to prevent danger if there is sudden jerking or catching.
10. On rooftops and other high locations, drive fasteners as you move forward. It is easy to lose your footing if you drive fasteners while inching backward. When driving fasteners against perpendicular surface, work from the top to the bottom. You can perform driving operations with less fatigue by doing so.
11. A fastener will be bent or the tool can become jammed if you mistakenly drive the fastener on top of another fastener or strike a knot in the wood. The fastener may be thrown and hit someone, or the tool itself can react dangerously. Place the fasteners with care.
12. Do not leave the loaded tool or the air compressor under pressure for a long time out in the sun. Be sure that dust, sand, chips and foreign matter will not enter the tool in the place where you leave it sitting.
13. Never attempt to drive fasteners from both the inside and outside at the same time. Fasteners may rip through and/or fly off, presenting a grave danger.

Repetitive motions hazards

1. When using a tool for long periods, the operator may experience discomfort in the hands, arms, shoulders, neck, or other parts of the body.
2.  While using a tool, the operator should adopt a suitable but ergonomic posture. Maintain secure footing and avoid awkward or off-balanced postures.
3. If the operator experiences symptoms such as persistent or recurring discomfort, pain, throbbing, aching, tingling, numbness, burning sensation, or stiffness, do not ignore these warning signs. The operator should consult a qualified health professional regarding overall activities.
4. The continuous use of the tool may cause repetitive strain injury due to recoil produced by the tool.
5. To avoid repetitive strain injury, the operator should not overreach or use excessive force. Additionally, the operator should take a rest when feeling fatigued.
6. Conduct a risk assessment regarding repetitive motion hazards. It should focus on muscular-skeletal disorders and be preferentially based on the assumption that decreasing fatigue during work is effective in reducing disorders.

Accessory and consumable hazards

1. Disconnect the energy supply to the tool, such as air or gas or battery as applicable, before changing/replacing accessories such as workpiece contact, or making any adjustments.
2. Use only the sizes and types of accessories that are provided by the manufacturer.

3. If dust or objects are emitted in the work area, reduce the emission as much as possible to reduce the health hazards and risk of injury.

Noise hazards

1. Unprotected exposure to high noise levels can cause permanent, disabling, hearing loss and other problems such as tinnitus (ringing, buzzing, whistling or humming in the ears).
2. Conduct a risk assessment regarding noise hazards in the work area and implement appropriate controls for these hazards.
3. Appropriate controls to reduce the risk may include actions such as damping materials to prevent workpieces from “ringing”.
4. Use appropriate hearing protection.
5. Operate and maintain the tool as recommended in these instructions, to prevent an unnecessary increase in noise levels.
6. Take noise reduction measures, for example placing workpieces on sound damping supports.

Vibration hazards

1.  The vibration emission during operation depends on the gripping force, the contact pressure force, the working direction, the adjustment of energy supply, the workpiece, and the workpiece support. Conduct a risk assessment regarding vibration hazards and implement appropriate controls for these hazards.
2. Exposure to vibration can cause disabling damage to the nerves and blood supply of the hands and arms.
3. Wear warm clothing when working in cold conditions, and keep your hands warm and dry.
4. If you experience numbness, tingling, pain or whitening of the skin in your fingers or hands, seek medical advice from a qualified occupational health professional regarding overall activities.
5. Operate and maintain the tool as recommended in these instructions, to prevent an unnecessary increase in vibration levels.

5. Sliding door

INSTALLATION

Selecting compressor

1. Nailing frequency (times/min)
2. Compressor air output per minute (L/min)
3. 0.69 MPa (6.9 bar)
4. 0.57 MPa (5.7 bar)
5. 0.45 MPa (4.5 bar)

The air compressor must comply with the requirements of EN60335-2-34.
Select a compressor that has ample pressure and air output to assure cost- efficient operation. The graph shows the relation between nailing frequency, applicable pressure and compressor air output.
Thus, for example, if nailing takes place at a rate of approximately 60 times per minute at a compression of 0.57 MPa (5.7 bar), a compressor with an air output over 25 liters/minute is required.
Pressure regulators must be used to limit air pressure to the rated pressure of the tool where air supply pressure exceeds the tool’s rated pressure. Failure to do so may result in serious injury to tool operator or persons in the vicinity.

Selecting air hose

CAUTION: Low air output of the compressor, or a long or smaller diameter air hose in relation to the nailing frequency may cause a decrease in the driving capability of the tool.
Fig.2
Use an air hose as large and as short as possible to assure continuous, efficient nailing operation.
With an air pressure of 0.49 MPa (4.9 bar), an air hose with an internal diameter of over 6.5 mm and a length of less than 20 m is recommended when the interval between each nailing is 0.5 seconds. Air supply hoses shall have a minimum working pressure rating of 1.03 MPa (10.3 bar) or 150 percent of the maximum pressure produced in the system whichever is higher.

Lubrication

Fig.3
To ensure maximum performance, install an air set (oiler, regulator, air filter) as close as possible to the tool. Adjust the oiler so that one drop of oil will be provided for every 50 nails.
When an air set is not used, oil the tool with pneumatic tool oil by placing 2 (two) or 3 (three) drops into the air fitting. This should be done before and after use. For proper lubrication, the tool must be fired a couple of times after pneumatic tool oil is introduced.
