PROCEDURE FOR UNPLUGGING YOUR CHIPPER
If your chipper is plugging, it is usually caused by allowing the engine to drop below required
R.P.M.’s. This can be resolved by simply shutting the feedwheel(s) off when the engine begins to lug
down. Operating the engine at speeds lower than full R.P.M.’s causes your chipper to plug.
Always
run the chipper at full engine speed.
If your chipper is equipped with the optional autofeed feature,
make sure it is set correctly. The setting for the low R.P.M. stop must be high enough not to allow the
chipper discharge to plug. Dull chipper knives also contribute to chipper plugging. Dull knives can create
slivers and chunks, causing the engine to lug excessively. Both of the aforementioned conditions cause
a plugging situation.
STEPS TO FOLLOW WHEN UNPLUGGING YOUR CHIPPER
1. Before attempting any type of maintenance disengage clutch, turn off engine, wait for the
disc/drum to come to a complete stop, install the disc/drum lock pin, disconnect battery, and
make sure the ignition key is in your possession.
2. Make sure the chipper disc/drum is
NOT
turning and then open the hinged portion of the chipper
hood.
3. Using gloved hands and some type of raking tool, dig the chips out of the chipper housing.
4. If the discharge chute is plugged, use a raking tool to pull the majority of chips out of the open
outlet end of the chute. Then, two people must remove the chute. Do not attempt this with one
person, because the chute can fall causing injury. If used properly, a hoist can be used to assist
in the removal of the chute.
5. Never allow one person to turn the chipper disc/drum when someone else is working inside the
chipper housing. More than likely, the chipper disc/drum will turn hard then loosen causing it to
turn faster. If another person is anywhere near the chipper disc/drum, they may be injured.
6. Never turn the chipper disc/drum by hand. Always use a pry bar or wood bar. This will prevent
the person turning the disc/drum from being injured should the disc/drum break loose.
7. Reinstall the discharge chute, mount securely and point it in a safe direction away from anything.
8. Never leave the chipper hood open and try to start the engine in order to engage the chipper
disc/drum to blow chips out of the housing, this is very hard on the P.T.O. of the chipper and may
burn clutch plates. Also, the flying debris is very dangerous. An exposed chipper disc/drum
turning very fast creates an unsafe condition. In other words,
DO NOT
start the chipper with the
hood open because it is just too dangerous.
9. Once the disc/drum turns freely, close the chipper hood, insert the hood pin, install the padlock in
the hood pin, reinstall the chipper hood engine disable plug, make sure the spring lock for hood
pin springs back to the correct operating position on disc chippers, start engine, properly engage
clutch and throttle to full speed. Insert a small branch into the feedwheel(s). If the chips
discharge properly, the chipper is clear and normal operation may resume.
