6. MAINTENANCE
Monthly Maintenance
1. TEST BRAKE
(This checks electrical wiring.)
STOP THE WIND GENERATOR IN A MODERATE
WIND (CHARGING BUT NOT FURLING) No
unusual difficulty or noise should be experienced in
stopping the propeller. A noise during braking can
indicate a disconnected wire.
NOTE
: If the propeller does not stop within 15
seconds of activating the brake, then turn it back “on”,
and try again later when there is less wind. Attempting
to stop the turbine in high winds can damage the
alternator.
3. INSPECT THE TOWER
Follow all inspection and maintenance requirements of
the tower manufacturer. Tighten all nuts and bolts,
especially wire clips, but do not over-tighten. Check
for cracks and bent or broken parts at the anchors and
base structure. Check for broken strands and tighten
guys.
2. CHECK MECHANICAL CONDITION
WATCH AND LISTEN FROM THE TOWER BASE.
Use binoculars. There should be no mechanical noise,
rattle or vibration. The propeller and tail must not
wobble. Lower or climb the tower for inspection, if
indicated. There should be no buzzing either heard or
felt with your hand on the tower mast. Go to Electrical
Problems, if indicated.
