Safety devices
The safety devices are designed to protect the user
and may not be de- activated or repurposed .
Relief valve
· If the hand spray gun is closed, the relief valve
opens and the high-pres- sure pump routes the
water back to the pump suction side . This prevents
the permissible working pressure from being
exceeded .
· he relief valve is set and sealed at the factory . It
may only be adjusted by the customer service .
Safety valve
The safety valve opens if the permissible maximum
allowable working pressure is exceeded (see
technical specifications); the water flows out .
The safety valve is set and sealed at the factory . It
may only be adjusted by the customer service .
Thermal valve
The thermal valve protects the high-pressure pump
from impermissible warming in circulation
operation if the hand spray gun is closed .
The thermal valve opens if the maximum permissi-
ble temperature of 68°C is exceeded and drains the
hot water .
High-temperature water and petrol
engine appliances
DANGER!
· Use only the fuel specified in the operating
instructions . The use of non-approved fuels
increases the risk of explosion .
· When refuelling petrol engine devices, take care
not to get any fuel on the hot surfaces .
· Always observe the special safety instructions for
petrol engine appliances contained in the operating
instructions!
· When operating the appliance in interior rooms,
sufficient ventilation and exhaust gas extraction
must be ensured (risk of poisoning) .
· The exhaust opening must not be blocked .
· Ensure that no exhaust gas emissions occur in the
immediate vicinity of the air inlets .
WARNING!
· Do not bend over or touch the exhaust outlet .
During burner operation do not touch the boiler .
(Risk of burns) .
Safety instructions
DANGER!
· Do not operate the high-pressure cleaner if fuel has
been spilt . Move the appliance to another location
and avoid all spark generation .
· Do not store, spill or use fuel in the vicinity of open
flames or appliances such as ovens, boilers, water
heaters, etc . that have a pilot flame or could
generate sparks .
· Keep easily inflammable objects and substances
away from the exhaust silencer (at least 2 m) .
· Do not operate the engine without the exhaust
silencer and check and clean this regularly (replace if
necessary) .
· Do not use the engine in wooded, bushy or grassy
terrain unless the exhaust pipe is fitted with a spark
