TOOL INSTALLATION INSTRUCTIONS 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

 

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 3 ft3/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.

Nailing frequency (timedmin.)

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 0.5 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 30 nails.

When n ir et 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.
