DANGER
To prevent injury or death from the unexpected start-up or fall of a raised machine, always stop the engine and remove

pull-type is raised, always close the lock-out valves, and place blocks under the rotary disc pull-type. Never work on or
beneath an unsupported rotary disc pull-type.

with, or near, blades.
DANGER
To avoid serious injury or death due to worn quick change plate, check the plates for damage before and after each
