• With engine OFF but still warm open oil drain valve and drain oil into appropriate receptacle. Note: To open valve, push in and turn counterclockwise. • Close oil drain valve. • Remove dipstick (if equipped) or oil fill cap. • Add new oil (28 ounces). Fill to FULL line on dipstick or to point of overflowing at oil fill cap. Do not overfill. • Replace dipstick or oil fill cap. INSTRUCTIONS FOR ADJUSTING OR REPLACING BELT BELT ADJUSTMENT The belt on your chipper should deflect 3/8” under three pounds of pressure as shown in figure 1 below. If it doesn’t, adjust per the following directions. Figure 1 • Remove belt guard. • Loosen engine bolts. • Tighten or loosen the nut on the belt tensioner until you have the correct tension as shown in figure 1. • Retighten engine bolts. • Check alignment of the clutch (item #12, pg.28) with the drive pulley (item #13, pg 28) by placing a straightedge across both faces as shown in figure 2. If adjustment is necessary, correct alignment by moving rotor pulley in or out on the rotor shaft. Do not make adjustment by moving the clutch on the engine shaft. • Replace belt guard. Figure 2 BELT REPLACEMENT • To replace the belt, follow the above belt adjustment directions. • After you have loosened the engine bolts, remove the old belt and replace it with a new one. • Set belt tension and alignment per above directions. NOTE: Check and re-tighten belt after initial break-in period, one hour of use. CENTRIFUGAL CLUTCH TECH TIPS CLUTCH PART NO. 030-0202 THE SHOES AND SPRINGS ON THE CLUTCH ARE NORMAL WEAR ITEMS. IF YOU NOTICE DECREASED PERFORMANCE OF THE CLUTCH THEY SHOULD BE CHECKED AND REPLACED IF NECESSARY. The clutch on your machine is designed for rugged, dependable service, however, it is important to understand the limitations of a clutch. A clutch is designed to provide load free starting of the engine, and slippage under excessive overloading of the driven application. These features help protect the engine from damages such as broken crankshafts and starters. The clutch obtains its power from engine RPM’s. The lower the engagement speed, and the higher the maintained engine speed, the more torque the clutch can transfer to the driven unit. Do not operate at less than full RPM’s. • At engine start-up, the engine of your chipper operates under no load until approximately 1000-1200 RPM’S at which speed the centrifugal clutch engages and begins driving the rotor. • Proper rotor speed is 2400 RPM +/- 200 RPM. • Do not tamper with the engine’s governor setting. The governor controls the maximum safe operation speed and protects the engine. Over-speeding the engine is dangerous and will cause damage to the engine and to the other moving parts of the machine. See your authorized dealer for engine governor adjustments. • Become familiar with successful operating conditions and avoid those that can overload and damage the machine. • Do not overload or attempt to chip material beyond manufacturers recommendation. Personal injury or damage to the machine could result. • Learn to recognize the sound of the machine when it is overloaded. • If the machine becomes jammed by overloading or any other cause, stop the machine immediately. • If you jam the machine and do not stop the engine, it can: • Burn the belt. • Ruin the clutch. • Only your operator experience will tell you how fast you can successfully feed limbs into the machine. • Clutch damage can be costly and it may not be covered under warranty. For this reason, it is important that you immediately shut off the machine if it becomes jammed. CLUTCH MAINTENANCE The centrifugal clutch on this machine is permanently lubricated and does not require oil or grease. If, after long periods of use, the drum wobbles excessively, replace the drum assembly. Always replace shoes and springs in sets. Whenever shoes are changed, replace all springs. CLUTCH REMOVAL 1. Remove clutch from shaft by removing bolt and washers. 2. Slide clutch off shaft. 3. Remove key from keyway. DISASSEMBLY OF EXISTING CLUTCH 1. Remove retainer ring and slide off drum assembly. 2. Unhook one spring from its shoe. Use tape wrapped pliers to avoid nicking spring. 3. Carefully note position of shoes. Remove shoes from hub. REASSEMBLE 1. Locate shoes correctly on hub for rotation required. 2. Place one end of each spring over a shoe pin, stretch spring just enough to clear pin on the other shoe. Use tape wrapped pliers to avoid nicking spring. Avoid over stretching that may damage spring. Repeat for all shoes. 3. Replace washer on hub shaft. 4. Reassemble drum to hub, secure with retaining ring. 5. Locate key in keyway of hub. 6. Slide clutch onto crankshaft, then washers. 7. Secure hub by tightening cap screw and allen head set screws. INSTALLATION OF A NEW CLUTCH 1. Clean shaft and remove any burrs. 2. Apply anti-seize compound to the shaft. 3. Place key in keyway on shaft. 4. Slide clutch onto shaft, secure with bolt, flatwasher and lockwasher (items #21, #22 and #23)....
