turned on when there is water shortage.
Temperature stop for exhaust gases
The temperature stop switches off the machine when
the waste gases have reached very high temperatures.
Winding protection contact
The winding protection contact in the motor winding of
the pump drive switches off the engine when there is a
thermal overload.
Safety catch
The safety catch on the trigger gun prevents the appli-
ance from being switched on unintentionally.
WARNING
Risk of injury! Appliance, accessories, supply lines and
connections must be in fault-free condition. If they are
not in a perfect state then the appliance must not be
used.
