4. Setup and Assembly

The EN420MP is a couple shaft attachment designed to connect to compatible Makita Multi-Function Power Heads.

1. Prepare Power Head: Ensure your Makita Multi-Function Power Head is turned off and the battery (if applicable) is removed or the spark plug cap is disconnected for gasoline models.
2. Align Shafts: Align the drive shaft of the EN420MP attachment with the coupling mechanism on your power head. The attachment is designed for quick and easy connection.
3. Secure Connection: Push the attachment firmly into the power head's coupling until it clicks into place or the locking mechanism engages. Refer to your specific power head's manual for detailed coupling instructions.
4. Verify Security: Gently pull on the attachment to ensure it is securely fastened and does not wobble. A loose connection can be dangerous during operation.
5. Adjust Blade Angle (Initial): Before starting, you can pre-set the blade angle using the angle change lever. This allows for optimal positioning for the task at hand.

5. Operating Instructions

Once the EN420MP attachment is securely connected to your power head, you are ready to begin trimming.

1. Power On: Start your Makita Multi-Function Power Head according to its specific operating instructions.
2. Adjust Blade Angle: Use the angle change lever to select one of the 13 available blade angles. This allows you to reach various heights and angles of hedges without excessive bending or stretching. The 135-degree adjustment feature also allows for positioning the blade parallel to the shaft for transport or storage.
3. Trimming Technique:
   • Hold the power head firmly with both hands.
   • Maintain a balanced stance.
   • Move the hedge trimmer smoothly and evenly along the hedge. The double-sided blade allows for cutting in both directions.
   • For thick branches, make several passes or use a pruning saw if the branch exceeds the cutting capacity of the blade.
   • Be mindful of the tip guard, especially when trimming close to walls, fences, or the ground, as it protects the blade from wear.
4. Overhead Trimming: The articulating head is particularly useful for overhead trimming. Adjust the blade to the desired upward angle and extend the power head. Ensure you maintain control and balance.
5. Low-Lying Trimming: Similarly, adjust the blade to a downward angle for trimming low hedges or ground cover without excessive bending.
6. Power Off: After use, turn off the power head and remove the battery or disconnect the spark plug cap.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your hedge trimmer attachment.

• Blade Cleaning: After each use, clean the blade thoroughly to remove sap, leaves, and debris. Use a stiff brush and a suitable cleaning solution.
• Blade Lubrication: Apply a light coat of machine oil or blade lubricant to the cutting edges after cleaning to prevent rust and ensure smooth operation.
• Blade Sharpening: If the blade becomes dull or damaged, it should be sharpened or replaced by a qualified service technician. A dull blade can cause excessive vibration and poor cutting performance.
• Inspect for Damage: Periodically inspect the attachment for any signs of damage, loose fasteners, or wear. Pay close attention to the articulating joint and the drive shaft connection.
• Storage: Always attach the blade cover before storing. Store the attachment in a clean, dry place, out of reach of children and away from direct sunlight or extreme temperatures. The 135-degree blade adjustment allows for compact storage.
