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. Read and follow instructions 
carefully.
Clean air cleaner every 25 hours under normal 
conditions or once a season. Clean every few hours 
under extremely dusty conditions. To service the air 
cleaner, refer to the separate engine manual 
packed with your unit.
The spark plug should be cleaned and the gap 
reset once a season. Check engine manual for 
correct plug type and gap specifications.
Removing The Flail Screen
If the discharge area becomes clogged, remove the flail 
screen and clean area as follows:
Stop the engine and make certain the Yard 
Vacuum has come to a complete stop.
Disconnect spark plug wire from spark plug and 
ground against the engine.
Remove the bag or blower chute (if equipped) from 
the unit as instructed in the OPERATION section to 
obtain access to flail screen. See Figure 11.
Figure 11 
Remove self-tapping screw on right side of unit that 
attaches to the fail screen. It may be necessary to 
remove the hose bracket hanger to get access to 
the hex screw. See Figure 12.
Remove hex screw on top of rear housing mounting 
bracket and the flange lock nut that secures flail

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 front hubcaps, flange lock nuts, front 
wheels, and wave washers that attach to the pivot 
arm assemblies. See Figure 13. 
Figure 13 
Remove the shoulder screws, thrust and bell 
washers that go through the pivot arms 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.
