6.1 Checks one month after installation
and every year
WARNING! Risk of electric shock
Always disconnect the supply voltage with
the maintenance switch before any service,
whether mechanical or electrical. Always lock
the maintenance switch in the off position. Do
not use the emergency stop button as a substi-
tute.
WARNING! Risk of personal injury
• Ensure that there is no vacuum present in the
system during service.
• Always disconnect the compressed air supply
before any service.
NOTE!
Check all power conductors and protective con-
ductors one month after installation and tight-
en, if required, to ensure good contact. Service
to the electrical equipment may only be carried
out by a qualified electrician.
One month after installation, and then every year,
perform the following checks:
• Check all power and protective conductors and
ground wire connections. Tighten, if required, to en-
sure good contact.
• Inspect the integrity of the dust separator.
• Ensure that the inside of the unit and the connec-
tion ducts are free from deposits. A build-up of de-
posits inside the duct system may cause the dis-
charge of static electricity.
• Inspect valves, hoses and seals for leakage.
• Clean the area around the unit and all areas where
the collected material is stored to ensure that there
are no dust deposits.
• Check that all signs/markings regarding safe opera-
tion are in place and that the personnel knows about
them.
• Verify the function of all emergency stop buttons,
alarms and signalling devices.
