CAUTION! If one blade breaks and the chopper must be operated without a replacement then the damaged blade and the blade directly opposite it must both be removed in order to keep the rotor in balanceCAUTION! Never replace only one blade for wear or breakage. Eight (8) blades MUST be installed to replace one (1) broken blade, or all the blades replaced at on time.

To Install Bushing:1.Removeallpaint,oilgrease,etc.fromtaperedsurfaceofbushingandboreofmatingpart.
2. See Standardmountingassembly-Figure1.
NOTE: If bushing does not slide freely on shaft, wedge a screwdriver blade into the saw cut and theflange OD to open the bore of the bushing. Caution: Excessive wedging will split the bushing.

CAUTION: Always use METRICclass 10.9 bolts and matching class 10 all steel lock nuts when installing blades.
IMPORTANT! The fan blades, located on the balance rings inside the chopper, must be installed in the direction shown (A). The straight edge of the blade cuts the air while the paddle trails behind and pushes the air.

IMPORTANT! Chopper balance MUST be maintained.
1.1 Replace BOTH blades on single support and BOTH blades opposite support (180 deg). Also, replace the four at the other end of the rotor, at the same axial distance from the balance ring.
Eight blades MUST be installed to replace one broken blade, or all the blades can be replaced at one time. This MUST be done to keep vibration to a minimum.
Never replace only one blade for wear or breakage
