2. Safety Information

Always observe basic safety precautions when using this product to reduce the risk of injury or damage.

• Keep out of reach of children.
• Wear appropriate safety gear, such as gloves and eye protection, during assembly and operation.
• Ensure all fasteners are securely tightened before each use.
• Operate the sweeper only on dry surfaces. Wet material is difficult to sweep and can cause clogging.
• Avoid using in windy conditions, as collected debris may be blown out of the collection bag.
• Do not attempt to sweep heavy or hard objects such as rocks, nuts, or pinecones, as this can damage the brushes or mechanism.
• Inspect the area to be swept for any obstacles or hazards before beginning operation.

3. Assembly Instructions

3.2 Handle and Collection Bag Attachment

4. Operating Instructions

Proper operation ensures efficient debris collection and extends the life of your sweeper.

4.1 Height Adjustment

• Locate the height adjustment knob on the front of the sweeper body.
• Rotate the knob to raise or lower the brushes. For optimal sweeping performance, the brushes should be set just below your grass height. This allows the brushes to make contact with the debris without digging into the turf.
• Adjust the height as needed for different terrains or debris types.

4.2 Sweeping Technique

• Push the sweeper at a consistent, moderate pace.
• The sweeper is designed for dry leaves, grass clippings, and light debris on flat surfaces and short, recently cut grass.
• Multiple passes may be required to collect 100% of the debris, especially with dense coverage.
• Periodically check and empty the collection bag as it fills to maintain optimal sweeping performance. Compressing the leaves in the bag can extend sweeping time before emptying.

5. Maintenance

Regular maintenance ensures your sweeper remains in good working condition.

• Cleaning: After each use, empty the collection bag and brush off any remaining debris from the brushes and sweeper housing. A garden hose can be used to rinse the brushes and housing, but ensure the unit is thoroughly dried before storage to prevent rust.
• Storage: Store the sweeper in a dry, protected area. The lightweight design allows for easy storage, including hanging on a wall.
• Inspection: Periodically inspect the brushes for wear and tear. Replace worn brushes to maintain effective sweeping. Check wheels and axles for smooth operation.
