5.10.1 UNPLUGGING:
Although the machine is designed to handle a
wide variety of material without any problem,
occasionally it plugs. If the machine plugs,
follow this procedure to unplug:
a. Enure the machine is in
safe condition
before beginning to unplug (see 2.2 pg 10)
b. Clear the area of bystanders, especially
small children.
c. Reverse the feed rollers to remove the
material from the feed hopper. Visually in-
spect and ensure all the material is out and
nothing is jammed or wedged between the
rollers and the rotor. If this does not un-
plug the chipper or the engine is stopped,
the plug must be removed by hand.
d. Pull any remaining material out of the feed
hopper and discharge hood.
e. Use a stick to poke loose any material
jammed into the discharge hood. Be
sure all the material is out and nothing
is jammed or wedged between the input
opening and the rotor.
f. Check that everyone is clear of machine
before restarting engine.
