Remember before working instructions for maintenance industrial fans
Before any work whatsoever on the fan, the following must be in compliance:
Tasks must be carried out only by qualified specialist personnel in compliance with these
instructions and the applicable regulations.
Use an isolator to disconnect the drive motor from the mains!
If there is no isolator, disconnect all the drive motor's terminals from the mains.
Ensure that it is not possible for the fan to be started unexpectedly during maintenance or
repair work (e.g. use a lockable isolator switch).
Wait until the rotor has come completely to a standstill!
Check the surface temperature for the danger of burns.
Before maintenance work, use suitable media to remove harmful or dangerous materials
which may have entered the fan in combination with the conveyed material.
Carry out recommissioning only after execution of the necessary safety tests.
Excluded from the above are tasks which can be carried out only in the operational state while
complying with the applicable safety and accident prevention regulations, e.g measurement of
scillation or shock pulses, the use of lubrication equipment to relubricate bearings during operation.
Failure to comply with these items may result in risk to life and limb for the maintenance personnel. If
the state of the fan means that suitable repair measures are no longer possible, then the fan must
immediately be taken out of use, and possibly replaced.
