Grinding Rotor Precautions
The grinding area is where material size reduction is
done. This area is a roughly cylindrical zone around the
rotor, from the discharge end of the feed chain on the
feed side of the rotor, around the sizing chamber, and
past the grates on the discharge side of the rotor.
Rotor Motion
Do not enter the feed hopper until the rotor has stopped
completely. Look through the belt guard (Figure 31) to
ensure that the rotor has come to a complete stop. The
belts must be absolutely motionless.
The rotor can free-spin for a long time after the clutch
disengages it from the engine. The rotor is massive, and
its energy while running is very great. Do not try to stop
it. Wait until it stops completely. Even slow rotor move-
ment can be hazardous.

To perform any maintenance on the grinder
rotor or its drive parts:
1.
Wait for the rotor to come to a full stop..
2.
Raise the compression roll and engage the safety
locking stops. See “Compression Roll Safety Lock-
ing Stops” on page 38.
3.
Shut down and lock out the battery disconnect
switch.
Rotor Precautions
•
While doing service or maintenance work, such as
inspection or changing bits, keep the machine
locked out and rotate the rotor slowly and with ver-
bal warnings to any others who may be working
close to the rotor.
•
Do not place yourself or any part of your body
under any pivoting component. Use the safety lock-
ing stop.
•
Never start the grinder or engage the clutch without
checking to be absolutely sure everyone is clear of
the rotor and its moving parts.
•
Do not feed materials into the hopper other than
those for which the grinder was originally designed.
•
Never enter or place yourself in a position to fall
into the hopper while the rotor is turning or the feed
chain is moving.
