Nozzle Height Adjustment The nozzle can be adjusted to any five positions, ranging from 5/8” to 4 1/8” ground clearance. The nozzle height has to be adjusted according to the conditions. Move the height adjustment levers forward or backward to adjust the nozzle upwards or downwards. See Figure 8. NOTE: In general, raise the nozzle height to vacuum a thick layer of leaves or to operate with the blower chute and lower the nozzle height for smoother surfaces.

Lubrication Wheels: Lubricate each wheel shoulder screw once a season with light oil. Refer to Figure 5. Nozzle height adjustment levers: Lubricate the pivot points of the nozzle height adjustment levers once a season with light oil. Refer to Figure 5. Engine: Follow the separate engine manual packed with your unit for lubrication instructions. Maintenance Engine Refer to the separate engine manual for all engine maintenance instructions. • Check engine oil level before each use as instructed in the separate engine manual packed with your unit.

See Figure 9. • Remove and clean the screen by scraping or washing with water. Reinstall the flail screen. Figure 10 Sharpening Or Replacing Chipper Blade Because the engine on this unit has a tapered crankshaft, a special impeller tool (part number 753- 0900) is required to remove the impeller assembly. For further assistance, contact your local service dealer. NOTE: When tipping the unit, empty the fuel tank and keep spark plug side up. • Disconnect the spark plug wire and ground it away from the spark plug. • Remove the lock nuts, front wheels, and wave washers that attach to the pivot arm assemblies. See Figure 11. Figure 11 Hex Screw & Flat Washer Lock Nut Flail Screen Remove Hex Screw Wave Washer Bell Washer Pivot Arm Assembly Lock Nut Shoulder Screw Height Adjustment Bracket 11 • Remove the shoulder screws and bell washers that go through the pivot arms and height bracket adjusters to the front support brace. • Remove the three screws on the upper housing that secure the nozzle cover and the nine screws that secure the lower housing to the upper housing. See Figure 12. Figure 12 • Remove lock nut that secures flail screen to the lower housing. The flail screen does not have to be removed. • Remove the hex bolt, lock washer, and flat washer that secure the impeller assembly to the crankshaft. See Figure 13.
