Using a Great Circle wood chipper involves understanding its features, following safety precautions, and performing proper operating and maintenance procedures. Always refer to your specific model's user manual for detailed instructions and safety information, as features and recommendations can vary.

Here's a general guide on how to use a Great Circle wood chipper, incorporating common practices and safety advice:

I. Before You Start (Safety First!)

1. Read the Manual: This is the most crucial step. Every Great Circle chipper model will have a specific instruction manual. Read it thoroughly to understand all safety warnings, operating procedures, and maintenance requirements. You can often find manuals on the Great Circle USA website.
2. Inspect the Chipper:
   • Blades: Ensure blades are sharp and in good condition. Dull blades reduce efficiency and can cause kickback.
   • Guards: Check that all safety guards, plates, and protective devices are in place and securely fastened.
   • Fasteners: Inspect all nuts, bolts, and screws for tightness. Tighten any that are loose.
   • Discharge Chute: Make sure it's clear of obstructions and pointed in a safe direction, away from people, property, or public areas.
   • Fuel/Oil (Gas Models): Check fuel and oil levels. Use fresh, unleaded gasoline (87+ octane) and the recommended type of oil. Do NOT use ethanol-blended fuel unless specifically stated in your manual.
3. Prepare the Work Area:
   • Level Ground: Place the chipper on a flat, level, and sturdy surface. Do not use it on slopes or slick surfaces.
   • Clear Area: Remove any foreign objects, debris, or tripping hazards from the chipping area.
   • Clear Bystanders: Ensure no one, especially children or pets, is within the operating zone.
4. Wear Appropriate Personal Protective Equipment (PPE):
   • Eye Protection: Safety goggles or a face shield are mandatory to protect against flying debris.
   • Hearing Protection: Earplugs or earmuffs are essential as chippers are loud.
   • Hand Protection: Wear sturdy work gloves (tight-fitting, without loose cuffs or drawstrings) to protect your hands from branches and sharp edges.
   • Foot Protection: Wear sturdy footwear, such as steel-toed boots. Never operate with sandals, sneakers, or bare feet.
   • Clothing: Wear tight-fitting clothing. Avoid loose clothing, jewelry, or long hair that could get caught in moving parts.

II. Starting the Chipper (Gas Models)

1. Position: Ensure the chipper is on flat, dry ground and stable (e.g., with wheel brakes engaged).
2. Fuel Shut-Off: Make sure the fuel shut-off valve is in the "ON" position.
3. Choke: If the engine is cold, move the choke control lever to the "CHOKE" position.
4. Throttle: Move the throttle control lever to the "FAST" position.
5. Start:
   • Recoil Start: Turn the ignition switch to "ON." Grasp the recoil starter handle and pull slowly until you feel resistance. Then, pull the cord rapidly to start the engine.
   • Electric Start (if equipped): Turn and hold the key in the "START" position until the engine starts, then release it to the "RUN" position.
6. Warm-up: Once the engine is running, slowly move the choke control lever back to the "RUN" position. Allow the engine to warm up at half throttle for 3-4 minutes before advancing to maximum speed.

III. Operating the Chipper (Feeding Material)

1. Understand Feed Chutes: Great Circle chippers often have multiple intake points:
   • Top Hopper: Typically for smaller, bulkier material like leaves, small twigs, and corn stalks (often with a 1/2" max volume for chipping/shredding).
   • Side Chute (Chipper Cone): Designed for larger branches and limbs (often up to 3" in diameter).
   • Leaf Vacuum Inlet (if equipped): For mulching leaves with an optional vacuum kit.
2. Feeding Branches (Side Chute/Chipper Cone):
   • Stand to the Side: Always stand to the side of the chipper cone when feeding branches to avoid kickback.
   • Feed Butt-End First: Insert branches butt-end (thicker end) first into the chute.
   • Let the Machine Work: Once the chipper grabs the material, let go and step away. Do not force material into the chipper.
   • Avoid Overloading: Do not try to chip branches larger than the chipper's maximum capacity (e.g., typically 3 inches for Great Circle models).
   • Never Reach In: NEVER place your hands, fingers, or any part of your body into the hopper, chipper cone, or discharge opening while the machine is running.
   • Use a Push Stick (if needed): For smaller pieces or to clear the chute, use a long branch or a non-metallic push stick. Do not use your hands or feet.
3. Feeding Leaves/Smaller Debris (Top Hopper):
   • Feed smaller, loose material into the top hopper.
   • Be mindful of dust and flying debris.

IV. Stopping the Chipper

1. Idle: Move the throttle lever to the "IDLE" position.
2. Turn Off:
   • Recoil Start: Turn the ignition switch to the "OFF" position.
   • Electric Start: Turn the key to the "OFF" position.
3. Wait for Blades to Stop: Always wait for the rotor and blades to come to a complete stop before leaving the machine or performing any checks.
4. Disconnect Spark Plug (Maintenance/Storage): For gas models, disconnect the spark plug wire and keep it away from the spark plug to prevent accidental starting, especially before any maintenance or long-term storage.

V. Maintenance Tips (Refer to your manual for detailed schedule)

• Clean After Each Use: Clear out all debris, sap, and bark from the hoppers, chutes, and around the blades to prevent clogs and rust.
• Check Engine Oil: Regularly check oil levels before each use. Change oil according to the manufacturer's recommendations (e.g., after the first 8 hours, then every 50 hours).
• Sharpen/Replace Blades: Sharp blades are crucial for efficiency and safety. Sharpen or replace blades regularly, as recommended in your manual (e.g., every 25 hours of use, or sooner if performance decreases).
• Lubricate Moving Parts: Lubricate bearings, pivot points, and other moving parts as specified in your manual.
• Check Air Filter: Inspect and clean the air filter regularly. Replace if it's too dirty or worn.
• Inspect Fuel System: If storing for an extended period, drain the fuel tank and run the engine dry to prevent stale fuel issues.
• Tighten All Fasteners: Regularly check and tighten all nuts, bolts, and screws.
• Proper Storage: Store the chipper in a dry, sheltered place, protected from moisture and extreme temperatures.

By following these guidelines and, most importantly, consulting your Great Circle wood chipper's specific user manual, you can operate your machine safely and effectively.
