Craftsman CMCBL720 Brushless Axial Leaf Handheld Blower Manual

Introduction

The Craftsman CMCBL720 Brushless Axial Leaf Handheld Blower is a cordless V20 outdoor power tool designed for clearing leaves, grass clippings, light snow, and loose yard debris. Its brushless motor and axial fan design provide efficient airflow without the fuel, extension cord, or routine engine maintenance required by many traditional blowers.

The blower delivers airflow of up to 350 CFM and air speeds of up to 100 MPH, giving it enough performance for patios, walkways, driveways, decks, and moderate residential cleanup. A variable-speed trigger helps you match airflow to the job: use lower output around flower beds and gravel, then increase power for larger piles of dry leaves. A boost button supplies additional force when heavier debris requires a short burst of power.

This handheld leaf blower is intended for homeowners, property-maintenance users, and anyone already using CRAFTSMAN V20 batteries. The tool-only version requires a compatible V20 battery and charger, while certain kits include a 4.0 Ah battery and charger. Its compact cordless design supports quick cleanup and easier movement around a property.

Use the CMCBL720 on dry, open surfaces and direct debris away from people, vehicles, windows, and buildings. It is best suited to routine residential maintenance rather than prolonged commercial-duty operation or moving wet, compacted debris.

Setup Guide: How to Use the CMCBL720 Leaf Blower

Inspect the blower: Check the housing, air inlet, nozzle, trigger, and battery compartment for damage or blockage. Do not operate a damaged tool.
Charge the battery: Place a compatible V20 lithium-ion battery on its charger and allow it to charge according to the charger instructions. Remove the battery from the charger when charging is complete.
Install the battery: With the trigger released and the blower switched off, slide the charged battery into the battery compartment until it locks securely.
Fit the nozzle: Attach the blower tube or nozzle supplied with your model. Confirm that it is fully seated before operation.
Prepare the work area: Remove stones, wire, glass, and other objects that could become airborne. Keep children, pets, and bystanders away.
Start gradually: Hold the blower firmly, point the nozzle toward the ground, and squeeze the variable-speed trigger. Increase speed as needed.
Use boost selectively: Press the boost control for short bursts when clearing heavier or compacted debris. Avoid continuous boost use when lower power is sufficient.
Shut down safely: Release the trigger, remove the battery, and clear debris from the air intake and nozzle after the tool stops.

Wear eye and hearing protection, long trousers, and closed-toe footwear. Never point the nozzle at people or animals, and do not use the blower in wet conditions unless the operating instructions specifically permit it. The CMCBL720 has no wireless pairing or connectivity function; setup consists of battery installation and mechanical nozzle attachment.

Troubleshooting the Craftsman CMCBL720

The blower will not start: Confirm that a charged compatible V20 battery is fully inserted. Remove and reinstall the battery, then inspect the contacts for dirt or damage.
Airflow is weak: Release the trigger, remove the battery, and inspect the nozzle and air inlet for leaves or debris. Clean the openings without inserting tools into the fan area.
Runtime is shorter than expected: Use a higher-capacity battery, reduce boost-mode use, operate with the variable-speed trigger at the lowest effective setting, and allow an overheated battery to cool.
The motor stops during use: Release the trigger and check for an obstructed intake, overloaded operating conditions, or an overheated battery. Allow the tool and battery to cool before restarting.
The battery will not charge: Verify that the charger is connected correctly, check the battery temperature, and try a known-compatible charger or battery if available.
Excessive vibration or unusual noise: Stop immediately, remove the battery, and inspect the nozzle, housing, and fan area. Do not continue using the blower if parts are cracked, loose, or damaged.
Error codes: The blower does not provide a user-facing error-code display. Charger indicator behavior should be interpreted using the charger manual rather than guessed from the blower.

Prevent problems by storing the blower and battery in a clean, dry location, keeping ventilation openings clear, and removing the battery before cleaning or transport. For warranty or product-support assistance, contact CRAFTSMAN customer service at 888-331-4569 during its published operating hours. Keep the model number, serial information, purchase documentation, and a description of the fault available.

Pros and Cons

Advantages

Strong cordless performance: Up to 350 CFM and 100 MPH is suitable for routine leaves, grass clippings, and light debris on residential surfaces.
Brushless efficiency: The brushless motor avoids brush replacement and is designed to use battery power efficiently.
Good control: The variable-speed trigger helps protect garden beds, gravel, and decorative surfaces from excessive airflow.
Convenient boost mode: A dedicated high-power function helps move dense piles without requiring a gas engine.
V20 platform compatibility: Existing CRAFTSMAN V20 users may be able to share batteries and chargers with other compatible tools.
Low-maintenance operation: There is no fuel mixing, spark plug, carburetor, or pull-start procedure.

Limitations

Battery dependent: Runtime is limited by battery capacity and can decrease when maximum power or boost mode is used frequently.
Tool-only variation: Some packages do not include a battery or charger, so buyers must confirm package contents before setup.
Not intended for every task: Wet leaves, packed debris, very large properties, and continuous commercial use may require a higher-capacity blower.
Noise and airborne debris: Hearing and eye protection remain necessary, even though the tool avoids gasoline-engine operation.

The CMCBL720 is a strong fit for homeowners who want a lightweight, cordless blower for regular yard cleanup and already use the CRAFTSMAN V20 battery platform. Users needing extended runtime, heavy-duty commercial durability, or maximum performance on wet debris may need a larger professional-grade blower.
