Section 8.0 Maintenance
Please carefully read the SAFETY INSTRUCTIONS in its entirety before commencing any type of
activity as there is potential for serious personal injury if not followed.
Only authorized personnel may perform adjustment of the electrical controls without cover,
when the electrical control is not connected to the supply voltage and in accordance with the
current safety rules.
Please note the following:
-
Before any type of inspection or maintenance activities are commenced, the dust
collector must be completely stopped, the electrical control must be disconnected in
such a way that the collector cannot be started inadvertently. The collector should not
be started again until all guards, doors etc. Have been restored correctly.
-
Only use original NEDERMAN spare parts for repairs.
8.1 Maintenance:
Fan
The fan wheel is carefully balanced at the factory to ensure vibration-free function. Vibrations
can arise during operation due to dust deposits on the fan wheel or loose fan wheel bolts.
These vibrations should stop once the fan wheel has been cleaned and/or tightened. Contact
a certified technician If the vibrations persists after cleaning and tightening of the fan wheel as
vibrations can reduce the life of the fan.
Motor
Normal motor maintenance comprises cleaning of the motor and lubrication of bearings per
the maintenance schedule. Electric motors are lubricated according to the manufacturer’s
instructions. Note: over-greasing of bearings can cause premature bearing and/or motor
failure. The amount of grease added should be carefully controlled. Bearing life is dependent
upon proper use and maintenance.
Filter Bags
The durability and life expectancy of the filter bags are heavily dependent on the operational
conditions, filter bag stress, type of dust and dust load but under normal operating conditions
and proper maintenance, filter bags should last 3 to 5 years.
Filter bags should be checked frequently for proper attachment to the hopper. Due to the
attachment design, it is common to erroneously assume the bags are secured properly. The
stainless steel “snap ring” sewn on the inside of the bottom of each bag, must be centered,
horizontally, in the cell plate. Extreme areas of wear and tear on certain filter bags may be
caused by malfunctions in the operation, and should be checked by a qualified technician.
