INSPECTION AND MAINTENANCE
The Rutland 913 requires no scheduled maintenance but an annual inspection
should be carried out to monitor the general condition of the system to ensure the
electrical and mechanical integrity and safety of the system.
WARNING!
Before inspection, the turbine should either be lowered to the ground
or tied to prevent the generator from turning. To stop the generator from turning
proceed as follows:
1. Either rotate the switch to stall mode on the HRDX Controller if used OR turn
the wind generator out of the wind (180°) using the tail, a hole is provided in the
tail fin to assist in this. The generator will gradually slow down.
2. Tie a blade to the mounting pole to prevent it from rotating.
Whilst the generator is stationary, the following routine checks should be
performed:
1. Check the blades for damage, eg chips or nicks. Replace any damaged blades.
The turbine should not be operated with damaged blades as this may cause
imbalance resulting in premature wear and possible failure. Check the blade
screws for tightness.
2. Check all other nuts, bolts and screws for tightness.
3. Check the yaw axis for free rotation.
4. Check tower assembly for condition.
5. Check the tension of the guy wires if applicable. The tension of guy wires
should be checked frequently during the first year.
6. The unit can be wiped with a mild detergent and rinsed with water to remove
dirt and debris.
Note: The Windcharger is designed for continuous running to achieve maximum
resistance to water ingress, should the unit be restrained for any extended period it
is recommended that it be covered.
