Assembly
Connecting the Air Supply (see figure A)
Make sure that the pressure of the compressed-air system is below the
maximum permitted rated pressure of the pneumatic tool. Firstly, set the
air pressure to the lower value of the recommended rated pressure (see
"Technical Data").
When in doubt, check the pressure at the air inlet with a pressure gauge
with the pneumatic tool switched on.
For maximum performance, the values for the supply-air hose 13 (con-
nection thread, maximum operating pressure, inner hose diameter, max-
imum hose length; see "Technical Data") must be observed.
The compressed air supplied should be free of foreign material and mois-
ture to protect the tool from damage, contamination, and the formation of
rust.
