Ensuring that the
cleaning device is
depressurised
Attempt to briefly activate the cleaning device without any compressed air supply to check
whether the cleaning device is depressurised. Proceed as follows:
Take protective measures:
- The brush head, brush head lifting device, wire cutter and cleaning nozzles could
start up. Therefore keep your body, especially your hands, face and hair, any ob-
jects and all clothing away from the parts referred to above
- wear ear protection
- wear protective goggles with side protection
Ensure that the cleaning device has been disconnected from the compressed air sup-
ply
Briefly turn the "Cleaning" screw on the cleaning device 90° to the right, then turn it
straight back to its original position
- If the cleaning device does not respond to the turning of the screw, the cleaning device
is depressurised
- If the cleaning device responds to the turning of the screw, the cleaning device is still
connected to a compressed air supply. If this is the case, you must disconnect the
cleaning device from the compressed air supply and check again that the cleaning de-
vice is depressurised before starting work
