1. Ensure all material on infeed conveyor has been ground.

2. Shut off Auto Feed.

3. Disengage mill/drum and wait for engine to reach idle.

Microprocessor will automatically reduce engine speed to idle

before clutch will disengage.

4. Wait for mill/drum rotation to stop. Confirm mill/drum has

stopped completely using display work screen. Indicator (1) on

display will turn gray when rotation has stopped. Indicator (1) will be shown in green anytime mill/drum

speed is greater than zero.

5. When mill/drum has come to a complete stop and all ground material has been discharged, shut off

discharge conveyor.

6. If remote control was in use, shut off remote.
NOTICE: Whenever practical and safe, allow engine to idle for one to five minutes

before shutting down after operating at full power. Please consult Machine’s Engine

behind shield (1) to confirm mill/drum has stopped.

6. In shingle grinding application, continue to run water system for five minutes after all ground product is

discharged to cool any remaining material to prevent gluing. This ensures the belt does not stick to any
