Be mindful of your surroundings and maintain a firm grip on the handle at all times. Following these precautions will ensure a safe and productive trimming experience;
Unboxing & Component Identification
Carefully unpack your Black & Decker Grass Hog. The box should contain the motor unit, trimmer head, adjustable handle, and a pre-wound trimmer line spool. Verify all components are present and undamaged. You’ll also find this user manual and potentially a small wrench for assembly.
Inspect each part for shipping damage before proceeding. The motor unit houses the power mechanism. The trimmer head is where the cutting line extends. The handle provides control and comfort during operation. Familiarize yourself with these core components. Note any included safety guards or shields. Retain the packaging for potential future transport or storage. A quick inventory ensures you have everything needed for successful assembly and operation.
Identifying Key Parts (Motor Unit, Trimmer Head, Handle)

The Motor Unit is the power source, typically featuring a grip area and the on/off switch. It’s the heaviest component. The Trimmer Head, attached to the motor, spins to deploy the cutting line. Observe the line exit point and the spool housing. The Handle is adjustable for ergonomic comfort, allowing you to customize the grip length and angle.
Locate the locking mechanism on the handle for height adjustments. Examine the trimmer head for the line feed button or system. The motor unit will have ventilation slots – avoid obstructing these. Understanding each part’s function is crucial for proper assembly, operation, and maintenance. Refer to the diagrams in this manual for visual clarification of each component’s location and features.

Included Accessories & Optional Attachments
Standard Accessories typically include a pre-wound trimmer line spool, a safety guard, and this user manual. Some models may also feature a shoulder strap for enhanced comfort during extended use. Optional Attachments significantly expand the Grass Hog’s versatility.
Consider the edging wheel for precise sidewalk and driveway edging. A fixed line cutting blade offers increased cutting power for thicker weeds. Extension poles are available for reaching difficult areas without bending or straining. Always ensure compatibility with your specific Grass Hog model before purchasing attachments. Black & Decker offers a range of genuine accessories designed for optimal performance and safety. Explore their website for the latest options.
Assembly Instructions
Before you begin, ensure the Grass Hog is switched off and unplugged (if electric). Assembly is straightforward, requiring no specialized tools. First, attach the handle to the motor unit, aligning the slots and firmly clicking it into place. Adjust the handle height to a comfortable position, securing it with the provided knob.

Next, install the trimmer head. Carefully align the head with the motor shaft and twist clockwise until it locks securely. Ensure the line spool is properly seated within the head before attaching. Double-check all connections for stability. Refer to the diagrams in this manual for visual guidance. Proper assembly is crucial for safe and efficient operation.
Attaching the Handle & Adjusting Height
Begin by locating the handle and aligning its base with the receiver on the motor unit. Slide the handle firmly into the receiver until it clicks, indicating a secure connection. To adjust the height, loosen the height adjustment knob located on the handle shaft.
Extend or retract the handle to your preferred working position, ensuring it’s comfortable and provides good control. Once the desired height is achieved, firmly tighten the adjustment knob to lock the handle in place. Regularly check the knob’s tightness during use to prevent slippage. A properly adjusted handle enhances ergonomics and reduces strain during trimming.
Installing the Trimmer Head & Line Spool
First, ensure the Grass Hog is switched off and unplugged for safety. Locate the trimmer head attachment point on the motor unit. Press the release buttons on the trimmer head, if present, and carefully remove any existing head. Next, take the new trimmer head and align it with the attachment point.
Push the trimmer head firmly onto the motor unit until it clicks securely into place. To install the line spool, open the spool compartment on the trimmer head. Insert the new line spool, ensuring the line feeds in the correct direction as indicated by the arrows on the compartment. Close the compartment securely. A properly installed spool ensures consistent line feed during operation.
Operating Instructions
Before starting, always inspect the area for obstructions and ensure a safe working environment. To begin, firmly grip the handle with both hands, maintaining a balanced stance. Connect the Grass Hog to a suitable power source – extension cords are often necessary for outdoor use. Press and hold the safety lock button, then squeeze the trigger to activate the motor.
Allow the trimmer head to reach full speed before contacting vegetation. Maintain a slight angle when trimming, avoiding direct contact with hard surfaces. For optimal results, use a sweeping motion, overlapping each pass slightly. Regularly check the line length and feed as needed. Always switch off and disconnect the tool before making any adjustments.
Starting & Stopping the Grass Hog
To start, ensure the trimmer head isn’t touching anything. Firmly grasp the handle with both hands. Press and hold the safety lock-off button – this prevents accidental activation. While maintaining pressure on the lock-off, squeeze the trigger to initiate the motor. Release the trigger to immediately stop the trimmer head. Always ensure the head comes to a complete standstill before setting the Grass Hog down.
For safety, always disconnect the power source (battery or extension cord) before performing any maintenance or changing the trimmer line. Never attempt to start or stop the tool with one hand. If the Grass Hog fails to start, check the power connection and line feed system. Remember to fully release the trigger for a complete stop.
Proper Trimming Techniques (Edge Trimming, General Trimming)
For edge trimming, tilt the trimmer head vertically, using the edge guide if equipped, and move along sidewalks, driveways, or flowerbeds. Maintain a consistent speed and avoid pressing the line directly against hard surfaces to prolong line life. General trimming involves sweeping the Grass Hog back and forth in a controlled arc, overlapping each pass slightly for a clean, even cut.
Avoid forcing the trimmer through thick weeds; instead, use multiple passes, gradually working your way through the growth. Keep the trimmer head at a slight angle to the ground for optimal cutting. Remember to walk at a comfortable pace and maintain a firm grip for precise control and safety during all trimming operations.
Line Feed System & Line Replacement
The Grass Hog utilizes an automatic line feed system, simplifying line advancement during operation. When the line shortens, simply activate the feed button – typically a small lever or button – to release more line. However, avoid excessive bumping, as this can lead to premature line wear and potential motor strain.

When line replacement is necessary, ensure the trimmer is switched off and disconnected from the power source. Access the spool compartment, remove the depleted spool, and install a new one, following the detailed instructions in the ‘Replacing the Trimmer Line’ section. Always use genuine Black & Decker replacement line for optimal performance and safety.

Understanding the Automatic Feed System

The Black & Decker Grass Hog features a convenient automatic line feed system designed for uninterrupted trimming. This system eliminates manual line advancement, enhancing user experience and efficiency. Activating the feed system is typically achieved by gently tapping the trimmer head against a firm surface while the motor is running.
This tapping action triggers a mechanism that releases additional line from the spool. It’s crucial to understand that the force applied should be moderate; excessive force can damage the system. The system is engineered to provide just the right amount of line for continued cutting, ensuring consistent performance. Regular use keeps the line at an optimal length.
Replacing the Trimmer Line (Step-by-Step Guide)
Begin by ensuring the Grass Hog is switched off and unplugged for safety. Next, locate and open the trimmer head’s line spool compartment – usually a twist-and-release mechanism. Remove the empty spool, noting its orientation for correct reinstallation. Insert the new trimmer line spool, ensuring the line end feeds in the direction indicated by the arrows on the compartment.
Securely close the compartment, aligning the locking tabs. Test the automatic feed system by tapping the head gently while the unit is running. If the line doesn’t advance, double-check the spool installation and compartment closure. Always use recommended line diameter for optimal performance and avoid damaging the feed mechanism.
Maintenance & Care
Regular maintenance extends the life of your Black & Decker Grass Hog. After each use, thoroughly clean the motor housing and trimmer head, removing grass clippings and debris with a dry cloth. Avoid using water directly on the motor. Inspect the trimmer line for wear and replace as needed, following the line replacement guide.
Periodically check the handle and locking mechanisms for tightness, and adjust if necessary. For long-term storage, clean the unit completely and store it in a dry location, away from extreme temperatures. Lubricate moving parts sparingly with a light oil to prevent corrosion. Proper care ensures consistent performance and reliability.
Cleaning the Grass Hog After Each Use
Post-trimming cleanup is crucial for maintaining optimal performance. Always disconnect the Grass Hog from its power source before cleaning. Remove any accumulated grass clippings from the trimmer head and around the motor housing using a dry brush or cloth. Avoid using water directly on the motor or electrical components – this can cause damage.
Pay attention to the line spool area, ensuring it’s free of debris. Wipe down the handle and shaft with a damp cloth. Regular cleaning prevents buildup that can hinder operation and reduce the lifespan of your Grass Hog. A quick clean after each use saves time and effort in the long run.
Lubrication & Storage Recommendations
Proper lubrication extends the life of your Black & Decker Grass Hog. Periodically apply a small amount of light machine oil to the trimmer head shaft, following manufacturer guidelines. Avoid over-lubrication, as this can attract dirt.
For storage, clean the unit thoroughly as described previously. Store the Grass Hog in a dry, covered location, away from extreme temperatures and moisture. Keep it out of reach of children. Consider hanging it to save space. Ensure the power cord is neatly coiled and secured. Long-term storage may benefit from a light coating of rust preventative on metal parts.

Troubleshooting Common Issues
If the Grass Hog won’t start, check the power cord connection and ensure the safety lock is engaged. For line feed problems, verify the line spool is correctly installed and not jammed. If trimming is ineffective, replace the trimmer line with a fresh spool of the recommended diameter.
Overheating may indicate excessive use or a blocked air vent – allow the unit to cool. Unusual noises could signal a damaged trimmer head; discontinue use and inspect. If the motor stalls, reduce the trimming load. Always disconnect the power before inspecting or attempting repairs. Refer to the warranty information for professional assistance.
