WARNING: Do not operate the chipper-
shredder without a muffler, or tamper with

Inspect periodically, and replace if necessary. If
your engine is equipped with a spark arrester
screen assembly, remove every 50 hours for
cleaning and inspection. Replace if damaged.
WARNING: Always stop engine,
disconnect spark plug wire, and move it
away from spark plug before performing
any adjustments or repairs.
