2.2 Safety devices on the machine
Circulation valve
(safety valve)
The pressure side of the high pressure pump is fi tted with a circulation valve (safety valve). This valve
cir cu lates the water back to the suction side of the pump when the spray handle is closed or if a nozzle
is blocked. The circulation valve has been constructed as a safety function ensuring that the pres sure will
never exceed the working pres sure by more than 25 bar. At this pres sure the circulation valve will au to mat -
i cal ly switch from high pressure to cir cu la tion mode.
Never let the machine run for more than 5 min. upon release of the spray handle as it may be damaged.
The valve has been adjusted and sealed from the factory.
This adjustment must not be changed!
The
cir cu la tion valve ensures that the machine becomes devoid of pressure when it is stopped.
Motor protection
The engine will automatically stop if the oil level is insuffi cient. The engine can be restarted when having
been re fi lled with oil.
2.3 General
1. It is not allowed to clean asbestos-containing surfaces with high pressure, unless using spe cial equip ment.
