WARNING

BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE, 

AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.

5.9 CLEARING A PLUGGED ROTOR

the chipper. To clear a plugged rotor, proceed as follows:
1. 

Turn off tractor. Allow all moving parts to come to a 

complete stop.

2. 

Open access cover (see Section 5.3).

3.  Clean the debris away from the chipper rotor. Turn 

the rotor by hand to be sure it is free to rotate. Be 

careful to avoid the chipper blades when cleaning out 

the debris.

4. 

Close access cover and secure (see Section 5.3).

5.  Follow start up procedures in Section 4.1.

If the machine becomes plugged, lift the engagement 

handle, shut off the engine, disconnect the spark plug 

wire and allow the machine to come to a complete stop 

before clearing debris. Do not operate the machine
