4. Setup and Installation

Before beginning installation, ensure the engine is completely off and cool. Disconnect the spark plug wire to prevent accidental starting.

1. Locate the Old Recoil Starter: Identify the existing recoil starter assembly on your Makita EB850, EB851, BBX7600, or BBX7650 tool.
2. Remove Mounting Screws: Use an appropriate screwdriver or wrench to carefully remove the screws securing the old recoil starter to the engine housing.
3. Detach Old Starter: Gently pull the old starter away from the engine. Observe how the starter rope engages with the flywheel or starter cup. This will be crucial for installing the new unit.
4. Inspect Area: Clean any debris or dirt from the mounting area on the engine.
5. Install New Recoil Starter: Position the new recoil starter assembly onto the engine housing, ensuring the starter pawls or engagement mechanism correctly aligns with the flywheel or starter cup.
6. Secure with Screws: Reinsert and tighten the mounting screws. Do not overtighten, as this can damage the housing.
7. Test Engagement: Slowly pull the starter rope a few times to ensure smooth engagement and retraction.

5. Operating Instructions

Once the recoil starter is correctly installed, follow your tool's specific starting procedure. Generally, this involves:

1. Ensure the spark plug wire is reconnected.
2. Set the choke and throttle according to your engine's starting requirements (refer to your tool's main manual).
3. If equipped, press the primer bulb several times until fuel is visible.
4. Grasp the starter handle firmly. Pull the rope slowly until you feel resistance, then give a quick, firm pull. Do not pull the rope to its full extension or let it snap back.
5. Repeat until the engine starts. Once started, gradually adjust the choke as the engine warms up.

6. Maintenance

Regular maintenance helps prolong the life of your recoil starter:

• Keep Clean: Periodically clean the recoil starter housing and rope area to prevent dirt and debris from interfering with its operation.
• Inspect Rope: Check the starter rope for fraying, cuts, or excessive wear. Replace the rope if any damage is observed.
• Check Spring Tension: Ensure the recoil spring provides adequate tension for the rope to retract smoothly. If the rope does not retract fully, the spring may need inspection or replacement by a qualified technician.
• Lubrication: Avoid over-lubricating internal components, as this can attract dirt. If lubrication is needed, use a dry lubricant or consult a service professional.

7. Troubleshooting

• Rope Does Not Retract:
  • Check for debris or obstructions around the rope and spring mechanism.
  • The recoil spring may be broken or dislodged. This usually requires disassembly and replacement of the spring.
• Rope is Hard to Pull:
  • Ensure the engine is not seized. Try turning the engine manually (if possible and safe).
  • Internal components of the starter may be binding due to dirt or damage.
• Starter Does Not Engage Flywheel:
  • The starter pawls may be worn, broken, or stuck.
  • The starter cup on the engine's flywheel may be damaged.

For complex issues or internal repairs, it is recommended to consult a professional service technician.

8. User Tips

• Always verify the model number of your tool against the compatible models listed in this manual to ensure correct fitment before purchase and installation.
• When pulling the starter rope, use a smooth, consistent motion. Avoid jerky pulls or letting the rope snap back, as this can damage the recoil mechanism.
• Store your garden tools in a clean, dry environment to prevent corrosion and accumulation of dirt in the starter mechanism.
