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 turbine mount fixings are secure and has not worked loose. Adjust if
required.
Ensure that the rotor blades rotate freely.
Ensure that all electrical connections are sound.
Annual Maintenance:
Inspect the turbine & support structure.
Ensure that the bearings are smooth and free running.
Inspect 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).
Remove any build-up of dirt and debris from the rotor blades using a mild detergent and
warm water.
Check the blade fixings for tightness.
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 should be replaced after five years of continuous
operation. This will ensure that the turbine’s performance and safety is not compromised.
Other Considerations:
The equipment used in the charging system (batteries, charge controller, PV panels,
invertors, 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.
