The following check ups should be carried out at regular 12 months intervals:
11.1 Rotor blades
Check if the blades show damages like broken edges, damaged surface or cracks. If
you notice any damage, the generator must not be used any longer. Check the
screwing one day after mounting and after that every 3 months. Eventually that you
can turn to a longer interval.
11.2 Srews
Check that all accessible screws are correctly fixed. Especially the hexagon srews of
the connection to the hub, the central shaft nut and the fixing of the mast must be
checked (see page 10, 11 and page 17, sketch 4, 5 ,6 ,7 and page 18, sketch 8, 9).
11.3 Bearings and gaskets
The bearing of the generator shaft and the bearing of the yaw shaft are permanently
lubricated. Please check these bearings as to free movement, bearing play and
watertightness. Deficient bearings must be replaced.
11.4 Corrosion protection
The complete housing is made of seaworthy alumine and additionally powder coated.
If the outer layer is damaged, there is a risk of corrosion. Please paint these spots
with suitable varnish (RAL9010)
11.5 Mounting construction
Check this construction in line with the instructions concerned (optional).
11.6 Electrical system
Please first stop the Silentwind generator so that all wires carry no voltage. Check if
all connections are properly fixed and not corroded. Possible corrosions must be
removed and treated with contact spray. Give special attention to the battery
connections: they must be clean and greased with vaseline. Check the battery in line
with the instructions of the producer and (if necessary) refill with destilled water. In
case more than 1 battery is used check that all batteries have the same capacity and
state of charge.
