manuals for the optional accessories.
2.4.1 Safety valve
A safety valve is located on the air motor hidden behind the covering
of the muffler on the machine.
The safety valve prevents
the maximum permissible
air inlet pressure from
being exceeded. If the air
inlet pressure exceeds the
permanently set threshold
value, the safety valve blows
off.
This is how to check the
function of the safety valve:
Fig. 2
: Safety valve
Increase the air inlet pressure briefly by approx. 10% over the
maximum permissible pressure according to the type plate. – The
safety valve must discharge.
WARNING
If the maximum permissible air inlet pressure is exceeded, parts
may rupture. The consequences may be personal injuries and
property damage.
➤
Never operate the machine without a safety valve or with a
defective safety valve!
➤
If it is necessary to replace the safety valve, please refer to
the spare parts list for the order number.
➤
With new safety valves, make sure that these are set to the
maximum permissible air inlet pressure of the machine (see
type plate or technical data) and sealed.
