Maintenance
Please follow the preventive maintenance programme listed below. This will ensure that the
turbine operates reliably and safely with good efficiency.
Always shut down the turbine before attempting to carry out maintenance.
Post-installation Checks (to be carried out one month after installation):
•
Check that the tower mount pins are secure and have not worked loose. Adjust if required.
•
Ensure that the rotor hub is still securely fitted.
•
Ensure that the rotor blades rotate freely.
•
Monitor the output. Ensure that the turbine and charge controller are functioning
correctly.
Annual Maintenance:
•
Inspect the tower / support structure.
•
Remove the turbine from its installation to a suitable workbench.
•
Remove the rotor blade assembly
•
Inspect the edges of the rotor blades for damage such as dents or chips. The blades will
become unbalanced if they are damaged. This will cause vibration, noise and poor
performance. If many dents have occurred along the edges of the blades, a new set of
rotor blades should be fitted (part numbers available in the Spares section).
•
Inspect the roots of the blades (attachment tabs) for signs of stress cracking or fatigue. A
new set of rotor blades should be fitted if any cracks of fractures have occurred (part
numbers available in the Spares section).
•
Remove any build-up of dirt and debris from the rotor blades using a mild detergent and
warm water.
•
Check the blade hub fixings for tightness.
•
Carefully remove the yaw mount bracket by unscrewing the 4 connection screws from the
sides of the LE-600 chassis. Inspect the slip rings and wipers for obvious signs of wear.
Replace the wipers if required (part numbers available in the Spares section). Reassemble
the yaw pivot carefully (do not pinch any cables).
•
Check that all electrical connections are sound and free from corrosion.
•
Generally ensure that the turbine is in good working condition and is safe for continued
use.
After five years of normal operation:
•
We recommend that the rotor bearings and rotor blades should be replaced after five
years of continuous operation. This will ensure that the tur
bine’s performance and safety
are not compromised.
Other Considerations:
•
The equipment used in the charging system (batteries, charge controller, PV panels, etc.)
should be maintained according to the instructions published by the relevant
manufacturer.
•
Where lead-acid batteries are used, it is especially important that they are maintained
carefully. Failure to do so will result in the batteries being rendered useless within a short
period of time.
