Processing Material; To Free A Jammed Flywheel - Northern Industrial Tools PTO 540 RPM Owner's Manual

· With the PTO and the tractor turned off, unplug the head by turning it backwards by hand
with the discharge chute and top section of the wrapper off.
· 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.
· Replace the clean-out door after all the chips are removed, being sure to use both the lock
washers and flat washers.
· Do not operate the unit without the guards in place.
Before stopping the chipper, be sure the all of the material is out of the head and out of the
feed roll.
· All of the material in the chute must be gone or the unit could jam on a small piece of
material. This can usually be cleared by turning the unit backwards by hand.
· ALWAYS disengage the PTO when leaving the Operating Zones or when moving the
Machine.
· Never move the Chipper while the PTO is turning.
· Always operate the Tractor PTO at 540 RPM when chipping.

PROCESSING MATERIAL

CAUTION: The Chipper is designed to accept wood only.
· The Chipper Knife mounted on a revolving flywheel turns branches fed into the Chipper
Hopper into "chips".
· Your PTO-Driven 4.5 Wood Chipper can process dry or green wood up to 4.5" in diameter.
· The Chipper will self-feed the wood once it contacts the knife edge so forcing the branches
into the Hopper is not necessary if the knife is sharp.
· Green wood will process quicker and easier than dry wood.
· Softwood processes easier than hardwood.
· Experience will teach you how different types of wood will chip and how fast you can
process them.
· When chipping branches, sometimes a tail will develop at the end of a branch. To avoid
this, rotate the branch while feeding it into the Chipper Hopper.
· Rotating the branch as you feed it into the machine will improve chipping performance.
· Use caution with small diameter green saplings and branches less than 2" in diameter.
Chip these grouped or bundled together to provide support. If the material is 2" or larger,
feed one at a time into the Chipper Hopper.
· Make sure the PTO-Drive 4.5" Wood Chipper finishes processing material in the Hopper
before disengaging the PTO and shutting the Tractor engine off.
· Do not force material into the Chipper. If the machine does not chip well, the Chipper Knife
may need sharpening or replacement, or the gap between the Knife and the Wear Plate
needs adjusting.
· NEVER THROW REMAINING STUBS OR KNOTS INTO THE CHIPPER HOPPER;
DAMAGE WILL RESULT.
· Extremely hard knots will not process very well. Feed them in slowly to reduce clogging.
Push any short stubs that have not self-fed through the chipper with the next branch to be
chipped.
· Cut the material to be chipped into manageable lengths of no more than five or six feet
before chipping.
· Overloading the chipper hopper will cause the rotor speed to decrease. If you hear the
engine RPM decreasing, stop feeding material into the chipper hopper until the engine has
returned to full speed.

TO FREE A JAMMED FLYWHEEL

CAUTION: Before performing any maintenance procedure or inspection on the chipper,
disengage the PTO, shut down the Tractor engine, remove the key, and wait for all moving
parts to come to a complete stop. Then disconnect the PTO shaft from the Tractor. Wait an
additional 5 minutes.
