Operating Instructions
Follow these guidelines for effective and safe operation of your Colwelt Rotary Edger.
Preparation Before Edging
- Mow First: Always mow your lawn before edging. This helps you clearly see the grass that needs to be trimmed along the edges and prevents the edger from getting bogged down in excessively long grass.
- Optimal Moisture: Use the edger when the ground is slightly moist, but not wet or muddy. Moist soil is easier to cut through than dry, hard earth.
- Clear the Area: Ensure the area to be edged is free of debris such as large roots, rocks, or other obstacles that could damage the blades or impede operation.
- Safety Check: Be aware of any underground utilities (power or water lines) or areas requiring access (manholes) where you plan to edge. Avoid using the edger near children, pets, or bystanders.
Edging Procedure
- Positioning: For best results, place the rubber wheel of the edger on the flat, hard surface (e.g., sidewalk, driveway) adjacent to the lawn edge, rather than directly on the lawn itself. This provides stability and guides the cut.
- Engage Blades: As you push the edger forward, the rotary wheel spins, causing the serrated blades to cut through the overgrown grass. The scissor design allows grass to be caught and cleanly trimmed between the two blades.
- Maintain Control: The extra-wide rubber wheel provides superior stability and traction, helping to keep the edger in a straight line. Apply steady, consistent pressure as you push the tool along the desired edge.
- Adjusting for Clogging: The three-position shear blade design helps prevent clogging. If grass accumulates, lift the edger slightly and clear any debris before continuing.
- Ergonomic Use: The 59-inch total length and ergonomic handle are designed for comfortable use, reducing strain during extended periods of edging.

Applications
The Colwelt Rotary Edger is ideal for defining and separating lawns from various hard surfaces and garden features:
- Sidewalks
- Driveways
- Patios
- Walkout basement pads
- Garden beds (works best on flat ground, less effective where lawn meets raised landscape beds)

Note: This tool is designed for creating crisp edges and is not intended for general grass trimming or heavy-duty brush cutting.
Maintenance
Proper maintenance will extend the life and performance of your Colwelt Rotary Edger.
- Cleaning: After each use, especially when working in moist conditions, clean any grass, soil, or debris from the blades, wheel, and frame. A stiff brush or cloth can be used.
- Drying: Ensure the tool is thoroughly dry before storing to prevent rust, despite its anti-rust coating.
- Inspection: Periodically inspect the blades for sharpness and damage. Check all fasteners for tightness and re-tighten if necessary. Inspect the wheel for wear or damage.
- Lubrication: While not explicitly stated, a light application of rust-preventative oil on the blade pivot points and wheel axle can help maintain smooth operation and prevent corrosion, especially before long-term storage.
- Storage: Store the edger in a clean, dry place, away from direct sunlight and extreme temperatures.

Troubleshooting
If you encounter issues while using your Colwelt Rotary Edger, refer to the following common problems and solutions:
- Difficulty Pushing / Not Cutting Cleanly:
- Ensure the ground is adequately moist, not too dry or too wet.
- Check for debris (rocks, roots, excessive grass) caught in the blades or wheel. Clear as needed.
- Verify that the wheel is on the flat, hard surface for proper guidance.
- Ensure you are applying consistent, forward pressure.
- Confirm that the lawn was mowed before edging.
- Wobbly Operation / Loose Parts:
- Inspect all assembly points (handle connections, wheel assembly) and tighten any loose fasteners.
- Ensure the reinforced metal support bracket is securely attached.
- Excessive Grass Buildup / Clogging:
- The three-position shear blade design is intended to minimize clogging. If it occurs, lift the tool and clear the blades.
- Ensure the grass is not excessively long before edging.
