1. Introduction
This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your Baotree 72cc Gas Powered Post Hole Digger. Please read this manual thoroughly before assembly or operation to ensure proper use and to prevent injury or damage.
2. Safety Information
Operating power equipment requires strict adherence to safety guidelines. Failure to follow these instructions can result in serious injury or death.
- Personal Protective Equipment (PPE): Always wear appropriate safety gear, including eye protection, hearing protection, heavy-duty gloves, and sturdy footwear.
- Bystander Safety: Keep all bystanders, children, and pets at least 15 feet (4.5 meters) away from the operating area.
- Ventilation: Never operate the engine indoors or in poorly ventilated areas. Exhaust fumes contain carbon monoxide, which is a colorless, odorless, and deadly gas.
- Fuel Handling: Handle fuel with extreme care. Store fuel in approved containers, away from ignition sources. Refuel in a well-ventilated outdoor area with the engine off and cool.
- Secure Grip: Maintain a firm grip on both handles during operation. Be prepared for sudden jolts if the auger encounters obstacles like rocks or roots.
- Clear Work Area: Ensure the digging area is clear of debris, hidden wires, pipes, or other obstructions.
- Engine Shut-off: Always turn off the engine before making any adjustments, clearing clogs, or performing maintenance.
3. What's in the Box
Your Baotree 72cc Gas Powered Post Hole Digger package includes the following components:
- 72cc Gas Powered Post Hole Digger Engine Unit
- 6-inch Diameter Auger Drill Bit
- 8-inch Diameter Auger Drill Bit

- Fuel Mixing Bottle
4. Assembly and Setup
Follow these steps to assemble your post hole digger. Refer to the diagram for visual guidance.
- Attach Handles: Securely fasten the dual-handle grip to the engine unit using the provided hardware.
- Connect Auger Bit: Select the desired auger drill bit (6-inch or 8-inch). Align the auger shaft with the output shaft of the engine unit. Insert the locking pin to secure it.
- Add Extension Rods (Optional): If additional digging depth is required, insert one or both extension rods between the engine unit and the auger bit. Ensure each connection is secured with a locking pin.
Once assembled, ensure all connections are tight and secure before proceeding.
5. Fuel Mixing
This post hole digger uses a 2-stroke engine and requires a specific gasoline-to-oil mixture. Incorrect fuel mixture can cause severe engine damage and void your warranty.
- Recommended Ratio: Mix unleaded gasoline with 2-stroke engine oil at a ratio of 25:1 (Gasoline:Oil).
- Mixing Procedure: Use the provided fuel mixing bottle. Fill with gasoline to the designated mark, then add 2-stroke oil to the corresponding mark for a 25:1 ratio. Shake well to ensure thorough mixing.
- Fuel Type: Use fresh, clean unleaded gasoline with an octane rating of 87 or higher. Use high-quality 2-stroke engine oil specifically designed for air-cooled engines.
- Storage: Do not store mixed fuel for extended periods (more than 30 days) as it can degrade and cause starting or performance issues.
6. Operating Instructions
Familiarize yourself with the controls and follow these steps for safe and efficient operation.
6.1 Starting the Engine
- Place the unit on a flat, stable surface.
- Ensure the fuel tank is filled with the correct 25:1 fuel mixture.
- Set the ON/OFF switch to the 'ON' position.
- Engage the choke (if cold start).
- Press the primer bulb several times until fuel is visible.
- Pull the starter cord firmly and smoothly until the engine starts.
- Once the engine starts, gradually disengage the choke. Allow the engine to warm up for a few moments before operating.
6.2 Digging Operation
- Hold the digger firmly with both hands on the ergonomic handles.
- Position the auger bit over the desired digging location.
- Slowly engage the throttle to begin rotating the auger. Apply gentle downward pressure.
- Allow the auger to bore into the soil. If resistance is met, slightly lift and re-engage to clear debris.
- The heavy-duty auger brake and quick-release throttle provide enhanced control during operation.
- To clear soil from the hole, lift the auger while it is still rotating slowly.
- For deeper holes, utilize the extension rods as needed. The modular design allows for digging depths up to over 3 feet (approximately 62 inches with extensions).
6.3 Shutting Down
Release the throttle and allow the engine to idle briefly. Move the ON/OFF switch to the 'OFF' position.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your post hole digger.
- Cleaning: After each use, clean the auger bit and engine unit to remove soil and debris. Use a brush and damp cloth. Do not use high-pressure water directly on the engine.
- Air Filter: Periodically inspect and clean the air filter. A dirty air filter can reduce engine performance and increase fuel consumption. Replace if damaged.
- Spark Plug: Check the spark plug for wear and proper gap. Clean or replace as needed.
- Fuel System: At the end of the season or before long-term storage, drain the fuel tank and run the engine until it stops to clear the carburetor of fuel. This prevents fuel degradation issues.
- Lubrication: Inspect the gearbox for any signs of leakage. Consult a service professional if lubrication is required for internal components.
- Auger Bits: Inspect auger bits for wear or damage. Sharpen or replace dull blades for efficient digging.
