– Please follow the national rules and

regulations for fuel spray jets of the re-

spective country.

– Please follow the national rules and

regulations for accident prevention of

the respective country. Fuel spray jets

must be tested regularly and the results

of these tests must be documented in

writing.

Safety devices serve to protect the user

and must not be rendered in operational or

their functions bypassed.

– If the hand spray gun is closed, the

overflow valve opens and the high pres-

sure pump diverts the water back to the

pump suction side. Thus the permissi-

ble working pressure is not exceeded.

– The overflow valve is set by the manu-

facturer and sealed. Setting only by

customer service.

The safety thermostat switches off the mo-

tor when the maximum permissible temper-

ature has been exceeded.
