1.
The chipper is a flywheel-and-knife type of chipper, not a shredder. The blades
actually chip the limbs as they are fed into the head. The blades must be sharp to
operate properly. Dirt, rocks, nails, or other foreign material will shorten blade life.
2. Before operating the chipper, review the machine checklist. After turning the chipper
by hand and making sure there are no obstructions in the head, start the tractor and
raise the chipper until the PTO shaft is within 15 degrees of straight.
3. Start the chipper slowly with the PTO engaged, and release the PTO clutch slowly.
Gradually increase speed until the tractor PTO speed is 540 RPM.
4. The material will feed into the head more easily if you start the pieces with the large
end first. The feed roll will fold branches as they are pulled into the hopper.
Occasionally, a limb fork may have to be cut to feed properly.
5. If the material stops feeding, sometimes a little push on the long end of the limb will
help.
6. If the material stops the feed roll, release the feed roll clutch by pushing it toward the
chute. Hold the clutch in the disengaged mode, and pull the material out of the
hopper. Release the feed roll clutch and the feed roll will turn again.
NOTE: Cut only clean material, or blade life will be shortened.
7. Watch the discharge chute while operating the unit. If the chips stop flowing, stop
feeding material into the unit by moving the feed roll clutch handle toward the chute
and pulling the material from the hopper. Most of the time this will be enough to clear
the chips out of the unit. If the unit slows down noticeably, first shut off the PTO
power, then the tractor, and remove the key.
8. Unplug the head by turning it backwards by hand with the discharge chute and top
section of the wrapper off.
9. Remove the chips from the top of the head. If this fails, remove the clean-out door,
located on the lower part of the front side-plate of the chipper below the main shaft,
then work the chips out of the case.
10. Replace the clean-out door after all the chips are removed, being sure to use both
