   Always move the unit to a safe storage area when not in use.

3. Never direct discharge material toward anyone. Avoid discharging material against a wall or obstruction. Material may ricochet back towards the operator.

4. Always stand to the side of the chipper cone when feeding tree limbs and branches into the unit, as tree limbs, branches, and harder woods may kick back while being chipped.

5. Always keep hands out of the chipper cone and shredder hopper when feeding materials.
   Never wrap fingers tightly around branches as you are feeding them into the unit, as a sudden inward surge could pull your hands and arms into the unit.

6. Never allow material to accumulate in the discharge area or shredding chamber, as this may cause new material being fed into the machine to kickback with strong force to injure you or other bystanders.

7. Never allow material to accumulate around the engine during Leaf Mulcher operation. This could result in a fire hazard, or overheating of the engine.

8. Never attempt to reposition or move the Leaf Mulcher unit while it is running. Doing so could cause the machine to tip over, and reaching to steady the unit could result in accidental insertion of your hands into the chipper cone or shredder hopper areas.

9. Never continue to operate the machine if it starts making unusual noise or vibration. Shut the engine off immediately, allow the rotor to stop, disconnect the spark plug wire and secure the wire away from the spark plug. Inspect the unit for any signs of damage or foreign material in the chipping or shredding areas. Remove any solid material that may be preventing the unit from operating properly.

10. Never attempt to clear material from the chipper cone, shredder hopper or discharge chute while the unit is running. Always shut the engine off, allow the rotor to come to a complete stop, and disconnect the spark plug wire before removing excess materials.
