5 INCH CHIPPER/SHREDDER/BLOWER
SERVICE & MAINTENANCE
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.
Feeding too large or too much material at once may plug
the chipper. To clear a plugged rotor, proceed as follows:
1. Stop engine, disengage rotor and allow machine to
come to a complete stop. Remove the spark plug
wire.
2. Remove the 3/8" carriage bolts securing the rotor
access cover. Turn discharge tube so it points toward
the ground as you open the cover.
3. Clean the debris out of the shredding rotor and/or
chipper top discharge area and tube. Turn the rotor
by hand to be sure it is free to rotate.
4. Replace spark plug wire, restart engine and resume
operation.
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
without proper guards and shields in place.
WARNING
Figure 5.5, Rotor Access

5.12 CLEARING A PLUGGED ROTOR
Loosen and remove the 3/8" carriage bolt securing the
knife access cover.
1. Stop engine, disengage rotor and allow machine to
come to a complete stop. Remove the spark plug
wire.
2. Remove the 3/8" carriage bolts securing the rotor
access cover. Turn discharge tube so it points toward
the ground as you open the cover.
3. Loosen the bushing bolts holding the drive pulley to
the shaft and remove the pulley.
4. Loosen the set screw in the lock collars. Using a
punch and hammer, tap the lock collars in a direction
opposite of normal rotation so that they can be
removed.
5. Unbolt bearings and lift rotor out of machine.
6. Remove bearings from rotor shaft.
7. Re-install rotor assembly and bearings and tighten
bolts to proper torque.
Check the condition of the drive belt annually or after
every 25 hours of operation, whichever comes first. If the
belt is cracked, worn, frayed, or stretched, replace it. To
replace the belt:
1. Stop engine, disengage rotor and allow machine to
come to a complete stop. Remove the spark plug
wire.
2. Place the engagement handle in the START position.
3. Remove the 5/16 x 3/4" bolts and washers securing
the shields in place and remove shields.
4.
Slip the drive belt off the pulleys. If necessary, loosen
the engine bolts and slide the engine forward to allow
the belt to slip off the pulley.
5. Inspect pulleys for wear. Replace the pulleys if they
are cracked or worn enough that the belt contact area
is not smooth and flat.
6. Place new belt over pulleys. Do not force or pry the
belt over pulleys as this may cause cord breakage. If
necessary, loosen engine mounting bolts and tip the
engine forward to allow the belt to be easily placed
over the pulley.
7. Align the engine so the crankshaft is parallel to the
rotor shaft. Tighten engine mounting bolts to 20 ft-lbs
torque.
