were
new,
adjust them as follows.
1.
Turn Hexagonal
U
nut loose.
2.
Truss screw in with the driver lightly till it stops turning, and then screw it back one quarter to a half turn.
3.
Turn Hexagonal
U
nut tight, holding Truss screw at the same time with a driver.
4.
Lubricate the blades after adjustments above with light oil.
5.
Start the engine and operate the engine throttle on and
off
for a minutes.
6.
Stop the engine and touch the blades with your hand.
If
they are warm enough for you to keep your hand on,
then you have made the proper adjustment.
If
they are
too
hot for you to keep touching, give Truss screw,
a
little
more turnback and repeat
5
to see
if
the are properly adjusted.
<NOTE>
Never fail to stop the engine before making the adjustment.
The blades have a slot around Truss screw. In case you find dust in the end of the slots, clean it.
