output per minute (L/min) 3. 0.83 MPa (8.3 bar) 4. 0.66

The air compressor must comply with the requirements
of EN60335-2-34.
Select a compressor that has ample pressure and air
output to assure cost-efficient operation. The graph
shows the relation between stapling frequency, applica-
ble pressure and compressor air output.
Thus, for example, if stapling takes place at a rate of
approximately 60 times per minute at a compression
of 0.83 MPa (8.3 bar), a compressor with an air output
over 50 liters/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.

Selecting air hose
CAUTION:
or a long or smaller diameter air hose in relation
to the stapling frequency may cause a decrease in
the driving capability of the tool.
► Fig.2
Use an air hose as large and as short as possible to
assure continuous, efficient stapling operation.
With an air pressure of 0.49 MPa (4.9 bar), an air hose
with an internal diameter of over 6.5 mm and a length
of less than 20 m is recommended when the interval
between each stapling is 0.5 seconds.
Air supply hoses shall have a minimum working pres-
sure rating of 1.03 MPa (10.3 bar) or 150 percent of the
maximum pressure produced in the system whichever
is higher.
Lubrication
► Fig.3
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 staples.
When an air set is not used, oil the tool with pneumatic
3
tool oil by placing 2 (two) or 3 (three) drops into the air
4
fitting. This should be done before and after use.
For proper lubrication, the tool must be fired a couple of
times after pneumatic tool oil is introduced.
