For UL Engines
1.
Rotate the blade to a recommended starting
angle of 17°. The blade and angle combination
generate a static RPM of roughly 2500.
2.
Rotate propeller 180° and repeat Steps 1-3
for the other blade.
A
After the blade pitch is set on both blades,
torque the Clamping Bolts to the
appropriate Value
(Table 1, Page 1). Follow
the symmetrical pattern and tightening each
bolt 1/8 to 1/4 turn at a time. It is important to
maintain an even gap between the hub half
to prevent a change in pitch angle.

NOTE
: after all mounting and clamping bolts
have been properly tightened, Check the
blade angles again to make sure they have
not changed.

IMPORTANT
:
After the first 5 hours of
operation, or any blade angle (pitch) change,
re-check all hub mounting bolts and blade
clamping bolts torque values.

NOTE
: To lower RPM, increase the blade pitch.
To increase RPM, decrease the blade pitch.
NEVER MASK AN ENGINE PROBLEM WITH
A PITCH CHANGE. If you are unsure, please
contact the factory
