To lock out or tag out the machine:
1.
Turn the
E
NGINE
switch to the Stop position on the
control panel to stop the engine.
2.
Turn off the Battery Disconnect Switch and remove
the key.
3.
Close, lock, and tag out the Battery Disconnect
Switch.
4.
Observe the following precautions:
•
Keep the Battery Disconnect Switch key and the
padlock key in a secure location when the
machine is shut down.
•
When more than one person is working on or
around the machine, use multiple lockout
devices so that each person has their own pad-
lock and key.
•
Do not disregard lockout procedures, doing so is
very dangerous.
Removing Jammed Material
Jams usually can be prevented by using good material
feeding practices. However, sometimes even the best
operators cannot prevent a jam.
Do not attempt to manually force jammed materials into
or out of the machine while it is running.
1
WARNING
Never try to remove jammed materials when the
machine is running. Stop and lock out the
machine.
1
WARNING
If stray material has blocked normal movement
of either the anvil or the compression roll hous-
ing, preventing it from closing or keeping it in a
raised position, manually removing that material
could allow the housing to fall suddenly.
Important
Do not attempt to use the clutch to clear a jam. If a
jam or blockage has occurred, trying to use the
clutch to clear it can cause the clutch lockout time
to cycle, preventing clutch engagement for 5 min-
utes. Using the clutch to clear jams rarely works.
Jams between the rotor and grates may be time-consum-
ing to clear. Access to the area can be gained by opening
the side access door, and, if needed, raising the anvil
housing. Refer to Section 5000 in the
6700B
Mainte-
nance Manual,
and “Entering the Rotor Discharge
◆
To clear a jam:
1.
Raise the compression roll to its fully raised posi-
tion. Use the safety pin to secure it. For detailed
instructions, see “To set the compression roll safety
locking stops:” on page 43.
2.
Shut down and lock out the machine. For detailed
instructions, see “To lock out or tag out the
machine:” on page 41.
3.
Remove the jammed material until the rotor can be
turned by levering with a piece of lumber.
4.
Restart the machine and return the compression roll
to the operating position.
Stored Energy Hazards
Some machine systems retain stored energy after the
engine has shut down and the Battery Disconnect
Switch has been locked out. Accidental release of this
energy can cause serious injury or death.
The following sources of stored energy are discussed in
this chapter:
•
Compression roll housing in a raised position
•
Rotor/grinder while coasting to a stop
•
Anvil housing in a raised (open) position
•
Pressurized gases and fluids
•
Batteries and other sources of electrical power
•
Discharge conveyor in an operating position
