3.2 Wind turbine
Monthly maintenance
Test brake
(This checks electrical wiring.)
Stop the wind turbine 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.
Check mechanical condition
Watch and listen from the tower base.
Use binoculars. The propeller and tail must not
wobble. There should be no mechanical noise, rat-
tle or vibration.
Lower or climb the tower for inspection, if required.
There should be no buzzing either heard or felt
with your hand on the tower mast. Go to section
Electrical problems on page 21
, if required.
Inspect the tower
Follow all inspection and maintenance require-
ments of the tower manufacturer. Tighten all nuts
and screws, especially wire clips. Check for cracks
and bent or broken parts at the anchors and base
structure. Check for broken wire strands and
tighten guys.
