AND USE

Selecting compressor

The air compressor must comply with the requirements of

ANSI B19.3 - 1981.

Select a compressor that has ample pressure and air output to assure cost-efficient operation. The graph shows the rela- tion between nailing frequency and compressor air output at a compression of 8.5 kgf/cm²G (120 PSIG). Thus, for exam- ple, when you drive about 10 nails 3.75 mm x 90 mm (0.148” x 3-1/2”) per minute, a compressor with an air output over 55 l/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.

NOTE:

•Nail size indicates diameter x length.

Selecting air hose

Use an air hose as large and as short as possible to assure continuous, efficient nailing operation. With an air pressure of 5 kgf/cm²G (70 PSIG), an air hose with an internal diameter of over 8.5 mm (5/16”) and a length of less than 20 m (6.6 ft.) is recommended when the interval between each nailing is

0.5seconds. Air supply hoses shall have a minimum working pressure rating of 10.7 kgf/cm²G (150 PSIG) or 150 percent of the maximum pressure produced in the system whichever is higher.

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.
