TOOL INSTALLATION INSTRUCTIONS AND USE

Selecting compressor

The air compressor must comply with the requirements of ANSI 619.3 - 1981.

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 40 times per minute at a compression of 6 kgf/cm2G(85 PSIG), a compressor with an air output over 95 l/minute is required. Pressure regu- lators must be used to limit air pressure to the rated pres- sure of the tool where air supply pressureexceeds 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

Nailing frequency (timeshin )

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 0.5 seconds. 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.

Lubrication

To insure 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

30nails.

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 lubri- cation, the tool must be fired a couple of times after pneu- matic tool oil is introduced.
