2 ROTOR BLADE A IMPORTANT! The paddle 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 & pushes the air. 1. The blades for your chopper must be installed as outlined. Note: If blades are installed other than as directed, damage to the chopper may result or performance may be significantly reduced. A 1) Always replace blades two pairs at a time, directly opposite each other through the center of the rotor. This should maintain rotor balance. Never replace only one blade for wear or breakage. You do not need to replace the corresponding two pairs on the other end of the rotor. 2) If a blade breaks and the chopper must be operated without a replacement then the damaged blade and the one directly opposite it must both be removed to maintain rotor balance. 3) Use only METRIC class 10.9 bolts (B) and class 10.9 DIN980V steel lock nuts (F) on the chopper rotor. 4) Use a torque wrench to tighten all M12 nuts to the recommended 69 ft-lb. 5) Always check for adequate clearance between the installed blades and the stationary knives. A minimum of 1/4 is required. Check clearance of all blades, even those that are not replaced. Do not operate the straw chopper unless this clearance is maintained for all blades. C D D E C F 2. Assembly order for blade pairs (B to F). E B A - Blade direction B - Hex cap screw C - Washer D - Blade, straight E - Bushing, straight blade F - Lock nut CAUTION: Always use METRIC class 10.9 bolts and class 10.9 DIN980V steel lock nuts when installing blades. Allowable torque range for blade mount nuts is 69 ft-lb. Torque values listed are for general use only, based on the strength of the bolt. DO NOT use these values if a different torque value or tightening procedure is given for a specific application. For stainless steel fasteners or for nuts on U-bolts, see the tightening instruction for the specific application. Tighten plastic insert or crimped steel type lock nuts by turning the nut to the dry torque shown in the chart, unless different instructions are given for the specific application. Dry means plain or zinc plated without any lubrication. 2

13 Appendix 2 - Bushings IMPORTANT: DO NOT USE LUBRICANTS IN THIS INSTALLATION To Install Bushing: 1. Remove all paint, oil grease, etc. from tapered surface of bushing and bore of mating part. 2. See Standard mounting assembly - Figure 1. NOTE: If bushing does not slide freely on shaft, wedge a screwdriver blade into the saw cut and the flange OD to open the bore of the bushing. Caution: Excessive wedging will split the bushing. 3. Standard Mount Slide bushing on shaft, flange first. If using the setscrew, snug it against the key. Excessive Torque will cause mating part to be eccentric. Position mating part in place on bushing aligning drilled holes in mating part with tapped holes in bushing flange. Using lockwashers, install capscrews thru the mating hub and into the bushing flange. (Note: S bushings can only be Standard Mounted. Be sure the three tapped holes in the mating hub do not align near the bushing saw cut. If they do, rotate the bushing 60 degrees.). 4. Use A Torque Wrench. Tighten all capcrews evenly and progressively in rotation to the torque value listed in the table. Excessive wrench torque, closing the gap between the bushing flange and mating hub, or the use of lubricants will break the mating hub. To Remove Bushing: 1. Loosen and remove all capscrews. 2. For Standard Mount, thread capscrews into tapped holes in mating part to jack against bushing flange. Tighten bolts evenly and progressively in rotation to separate the two components. 3. Loosen setscrew to slide bushing from shaft. Standard Mounting Screw Tightening Information Tapered Bushing Size & Thread of Capscrew Ft.-Lbs. To Apply With Torque Wrench SK 5/ SF 3/ Fig. 1 13
