Replacing Oil Plug on Bonfiglioli Motors
(24’ Powerfoil/Wickerbill and PowerfoilPlus Models Only)
CAUTION: The oil plug on the fan models listed above must be replaced with the oil vent cap to optimize performance. The
proper oil vent cap is packaged in a bag attached to the motor unit.
If your fan model does not require an oil vent cap, proceed to “Installing Airfoils” (p. 26).
1. Replace Oil Plug
CAUTION: Do not remove oil plug until fan is properly mounted! If the oil plug is removed before the fan is mounted, oil in the
gear reducer may spill out.
NOTE: These instructions apply to 24’ Powerfoil/Wickerbill and PowerfoilPlus models only!
Remove the oil plug and install the oil vent cap as shown. Screw the cap into place by hand, being careful not to strip the threads.
