Air supply
1. Use clean, Dry and Regulated compressed air at 4-7 bar (60-100psi)
2. Never exceed maximum and minimum pressure. Too low or too high pressure would cause noise, fast-worn
or misfiring.
3. When connecting air supply always keep hands and body from discharge area of tool.
4. A filter-regulator-lubrication is required and should be located as close to tool as possible.
5. Keep air filter clean. A dirty filter will reduce the air pressure to the tool causing a reduction in power and
efficiency.
6. For better performance, install a quick connector in your tool and quick coupler on the hose if possible.
7. Be sure all connections in air supply system are sealed to prevent air loss.
Loading fastener and operation

2. Release the latch and pusher, slid the pusher against the nails.
3. Connect the tool to the air supply. Make sure the air pressure is in the correct range denoted in the
Technical Data.
4. Then test the driving depth in a sample piece of wood before using. If the fasteners are being driven too far
or not far enough, adjust the regulator to provide less air pressure or more air pressure.
5. Never operate tool unless safety nose is contact with workpiece. Do not operate tool without fasteners or
damage to tool may result.
6. Never fire fasteners into air because fasteners may injury operator or others and damage to tool may result.
7. The air tool is equipped with safety stand mechanism that disable tool unless safety stand is pushed against
work. Hold gun body firmly and press safety stand on workpiece where fastener is to be applied. Pull the
