dle, kickback forces are produced at the spraying device and when the spray lance is held at an angle, a torque is also created. The spray handle and spray lance must therefore be held firmly with both hands • Check that cleaning will not result in dangerous substances (e.g. asbestos, oil) being washed off the object to be cleaned and harming the environment • During use of high pressure cleaners, aerosols may be formed. Inhalation of aerosols can be hazardous to health.
restart after a few minutes when the thermal sensor has cooled. Unloader valve: Unacceptably high pressure is fed back without residual pressure via a bypass line into the intake line of the pump when the safety device is tripped. The unloader valve is set and sealed at the factory and must not be adjusted. Locking device on spray handle: The spray handle features a locking device. When the pawl is activated, the spray handle cannot be operated.
