Rutland 914i Windcharger
Maintenance and Troubleshooting
Inspection and Maintenance
The Rutland 914i 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 charge regulator 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 you wish to take the unit
out of service for an extended period it is recommend that the unit be
removed from the mounting and stored in a dry location or covered.
