Chipping and Shredding:

• Side Chute (Chipping): For branches and limbs up to 3 inches in diameter. Feed material slowly and steadily into the side chute. Do not force material.
• Top Hopper (Shredding): For smaller twigs, leaves, and brush with a maximum volume of 1/2 inch. Drop material into the top hopper.
• Maintain a steady feeding pace to prevent clogging.
• Avoid feeding wet material, as it can cause clogging.
