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, wait for the drum to come to a complete
stop, turn off engine, remove ignition key, be sure to have the ignition key in your possession, disconnect
the battery and install the disc/drum lock pin.
2. There must be at least two people on site during maintenance and service procedures in case an accident
should occur.
3. Make sure the chipper drum is
NOT
turning and then open the hinged portion of the chipper hood.
4. Using gloved hands and some type of raking tool, dig the chips out of the chipper housing.
5. 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. If the discharge chute needs to removed, use some sort of mechanical device like an overhead
hoist, loader, lift truck, etc. that is rated to lift the discharge. Follow all OSHA instructions for lifting.
6. Never allow a person to turn the chipper drum when someone else is working inside the chipper housing.
More than likely, the chipper drum will turn hard then loosen causing it to turn faster. If another person is
anywhere near the chipper drum, they may be injured.
7. Never turn the chipper drum by hand. Always use a pry bar or wood bar. This will prevent the person
turning the drum from being injured should the drum break loose.
8. Reinstall the discharge chute, mount securely and point it in a safe direction away from anything.
9. Never leave the chipper hood open and try to start the engine in order to engage the chipper 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 fl ying debris is very dangerous. An exposed chipper 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.
10. Once the 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.
If the chipper is properly maintained and operated correctly, the chipper should not plug. In the unlikely
event that the chipper becomes plugged, do not attempt to clean out the discharge or chipper housing in the
fi eld. Take the machine to a local dealer or professional shop. If the machine is a rental, take it back to the
rental company.
DANGER
!
If the discharge or hood need to be removed, always use some sort of mechanical device like an overhead
hoist, loader, lift truck, etc. that is rated for lifting that component. Follow all OSHA instructions for lifting.
