Sharpening Or Replacing Chipper Blade
IMPORTANT: 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. The instructions below involve use of this tool.
NOTE: When tipping the unit, empty the fuel tank and
keep spark plug side up.
• Disconnect spark plug wire and ground it away
from the spark plug.
• Remove flange lock nuts and front wheels that
attach to pivot arm assemblies. See Figure 11.
Figure 11
• Remove the shoulder screws and thrust and bell
washers that go through the spring levers and pivot
arms/height adjuster bearings to the front support
brace. The front support brace and lock nut can be
removed at this time as well.
• 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.
