INSPECTIONS AND MAINTENANCE
10.1 Periodic inspections
While your Superwind 350/48V has been designed to run for years without maintenance,
periodic inspections are required for reliability and safety. The inspections described below
should be performed annually or after any event that could result in damage to the unit
(lighting strike, foreign objects striking the rotor, etc).
In some turbine applications (such as operation on a yacht) daily
inspections in and around the working area of a turbine is
recommended. Look for equipment or rigging that may have been
moved by others that could impact the turbine’s use and operation.
Keep the working area of the turbine free and clear!
Before performing any inspection, disconnect the Superwind/48 V from the batteries by
shutting down the rotor as described in Section 9.2).
Do not approach a turning rotor.
Never attempt to stop the rotor by hand.
Conduct inspections of the mast or wind generator on a calm
and windless day only.
Do not step or allow other persons to place themselves under
hanging loads (such as a tilted mast).
10.1.1 Rotor blades
Check each rotor blade for damage (cracks, broken edges, unusual discoloring etc.).
If any blade damage is found, stop operation of your Superwind/48 V until the rotor
blade set has been replaced. As discussed previously, rotor blades must be replaced
as a set. Never mix rotor blades from different sets as decreased performance or
damage due to an unbalanced rotor will likely result.
Dirt on the blades affects airfoil performance and reduces power output. Remove dirt
by cleaning the blades with a sponge using soap and water. Do not use abrasive
cleaners or those containing strong chemicals.
10.1.2 Bolted connections
Check all accessible bolted connections, ensuring each is tightened to the correct
torque. Pay particular attention to the bolts securing the rotor blades, hub, wind vane
and yaw shaft. Refer to Section 7 for additional information.
10.1.3 Bearings
The generator and yaw shaft bearings are sealed and lifetime lubricated. Check the
bearings for smooth operation, clearance, or leakage. Defective bearings must be
replaced at an authorized service facility.
