TOOL INSTALLATION INSTRUCTIONS AND US€

Selecting compressor

The air compressor must comply with the require-

ments of ANSI 819.3 - 1981.

Select a compressor that has ample pressure and air

output to assure cost-efficient operation. The graph

8 3

shows the relation between nailing frequency, applica-

a

 

.-

ble pressure and compressor air output. Thus, for

a

 

-

 

example, if nailing takes place at a rate of approxi-

a 2

-

 

mately 40 times per minute at a compressionof 0.49

m

 

b

 

MPa (70 PSIG). a compressor with an air output over

t

l

2 ft3/minuteis required. Pressure regulators must be

ii

 

used to limit air pressure to the rated pressure of the

5

 

tool where air supply pressure exceedsthe tool’s rated

0 0

 

 

pressure. Failureto do so may result in serious injury

 

 

to tool operator or persons in the vicinity.

 

 

Selecting air hose

 

 

Use an air hose as large and as short as possible to

 

 

assure continuous, efficient nailingoperation. With an

 

 

air pressure of 0.49 MPa (70 PSIG), an air hose with

 

 

an internal diameter of over 6.5 mm (1/4”) and a length

 

 

of less than 20 m (6.6 ft.) is recommendedwhen the

 

 

interval between each nailing is 0.5 seconds. Air

 

 

supply hoses shall have a minimum working pressure

 

 

rating of 1.06 MPa (150 PSIG) or 150 percent of the

 

 

maximum pressure produced in the system whichever

 

 

is higher.

 

 

CAUTION:

I

 

Low air output of the compressor, or a long or smaller diameter 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 50 nails.

Nailing frequency (timeshnin

air hose in relationto the nailing frequency

When an air set is not used, oil the tool with pneu- matic tool oil by placing 2 (two) or 3 (three) drops into

the air fitting. This should be done before and after IPneumatic use. For proper lubrication, the tool must be fired a

couple of times after pneumatic tool oil is introduced.
