AIR-POWERED COIL ROOFING NAILER 058-8179-2
Air system
• Always use clean, dry, regulated, compressed air at 5 to 7 bar (70 to 100 psi).
• Do not exceed the maximum or minimum pressures. Operating the tool at the wrong pressure
(too low or too high) will cause excessive noise or rapid wear, or misfiring.
• It is recommended that a filter-regulator-lubricator be used and be located as close to the tool
as possible.
• If a filter-regulator-lubricator is not installed, place up to 6 drops of pneumatic tool oil into the
air inlet plug before each use.
• If a filter-regulator-lubricator is installed, keep the air filter clean. A dirty filter will reduce the
air pressure to the tool, which will cause a reduction in power, efficiency, and general
performance.
• For optimal performance, install a quick connector to the tool and a quick coupler on the
hose, if applicable.
• Verify that all connections in the air supply system are sealed in order to prevent air leakage.
WARNING!
Potential hazard that could result in serious injury or loss of life.
•Keep hands and other parts of the body away from the tool’s discharge and
working areas when connecting the tool to the air supply. Failure to comply
could lead to serious injury or loss of life.
• Do not use the tool if it is not in proper working order.
• Do not use oxygen or any other combustible or bottled gas to power this tool.
• Do not use this tool in the presence of any flammable liquids or gases.
• Keep hands and other parts of the body away from the firing head during use.
• Do not point the tool towards the operator or other people.
• Do not attempt to clear a jammed nail when the air hose is connected.
•Do not drive a nail on top of an existing nail. Failure to comply could lead to
serious injury or loss of life.
