It is recommended that the chipper blades are sharpened every 5-15 hours of chipper operation.
SERVICE & MAINTENANCE 4.3 SETTING BLADE CLEARANCE (CONT.) 6. Check belt tension and adjust if needed. The belt deflection at the center of the belt should be 7/16" when a 20 lb. load is placed against it (see Figure 4.6). To Adjust Chipping Anvil: 7. Reinstall belt guard. 1. Lift rotor access cover and expose rotor. Loosen the two 1/2 inch bolts that hold the chipper anvil to the frame. 8. Depress belt engagement pedal, start engine, engage drive belt, and test unit. Readjust pulleys if needed. 2.
SERVICE & MAINTENANCE 10. Slide bushing onto shaft with flange against bearing and lock bushing to shaft. Attach large pulley to bushing. Replace drive belts on pulleys, slide engine back into place, and retighten bolts. Check alignment of pulleys and belt tension. Adjust if needed. 4.5 CLEARING PLUGGED ROTOR WARNING If the machine becomes plugged, shut off power source, disconnect spark plugs, and allow the machine to come to a complete stop before cleaning debris.
SERVICE & MAINTENANCE 4.7 greaseable bearings The 4 inch chipper models have greaseable bearings and pivots that require grease every 25 hours: • Two bearings on the rotor shaft. • One grease zerk on discharge chute. 4.8 pto lubrication 1. Every 8 hours, lubricate PTO cross journals. Make sure grease purges through all bearings (Figure 4.7). 2. Every 8 hours, lubricate PTO inner tubes. Pull apart the telescoping members and add grease with a brush (Figure 4.7). 3.
