• For user servicing, the machine must be dismantled, cleaned
and serviced, as far as is reasonably practicable, without
causing risk to the maintenance staff and others. Suitable
precautions include decontamination before dismantling,
provision for local filtered exhaust ventilation where the
machine is dismantled, cleaning of the maintenance area and
suitable personal protection.
• Perform a technical inspection at least annually, consisting of,
for example, inspection of filters for damage, air tightness of the
machine and proper function of the control mechanism.
• Besides the operating instructions and the binding accident
prevention regulations valid in the country of use, observe
recognized regulations for safety and proper use.
• When dust removers are used, the rate at which air is
exchanged in the room must be adequate if the exhaust
air from the vacuum cleaner is blown into the room (please
observe regulations valid in your country).
• Before starting work, the operating staff must be informed on
- use of the vacuum cleaner
- risks associated with the material to be picked up
- safe disposal of the picked up material.
• Before transporting the collection tank, close all the locks. Do
not tilt the cleaner if there is liquid in the collection tank. Do not
use a crane hook to lift the cleaner.
• For class M machines, the outside of the machine should be
decontaminated and wiped clean or treated with sealant before
being taken out of a hazardous area. All the machine parts
shall be regarded as contaminated when removed from the
hazardous area and appropriate action taken to prevent dust
dispersal.
