Setup

Assembly:

1. Unpack all components from the packaging.
2. Attach the trimmer head assembly to the main shaft, ensuring it clicks securely into place.
3. Adjust the multi-position handle to a comfortable operating height and tighten the locking mechanism.
4. Ensure all connections are firm before proceeding.

Fueling the Trimmer:

• The TB22 uses a 2-cycle engine, requiring a specific gasoline and oil mixture. Refer to the engine manufacturer's instructions for the correct mixing ratio (typically 40:1 or 50:1).
• Use fresh, clean, unleaded gasoline with an octane rating of 87 or higher.
• Mix the fuel in a separate, approved fuel container.
• Carefully pour the mixed fuel into the trimmer's fuel tank, avoiding overfilling.
• CAUTION: Always refuel in a well-ventilated area, away from open flames or sparks.

Operating Instructions

Starting the Trimmer:

1. Place the trimmer on a flat, stable surface.
2. Prime the engine by pressing the primer bulb several times until fuel is visible.
3. Set the choke to the "FULL CHOKE" position.
4. Pull the starter rope firmly and smoothly until the engine attempts to start (usually 1-3 pulls).
5. Once the engine "pops" or attempts to start, move the choke to the "HALF CHOKE" position.
6. Pull the starter rope again until the engine starts.
7. Allow the engine to warm up for a few seconds, then move the choke to the "RUN" position.
8. If the engine does not start after several pulls, refer to the Troubleshooting section.

Using the Trimmer:

• Wear appropriate safety gear, including eye protection, hearing protection, long pants, and sturdy footwear.
• Hold the trimmer firmly with both hands, maintaining a balanced stance.
• Keep the cutting head away from your body and other objects.
• To extend the cutting line, tap the bumphead lightly on the ground while the engine is running at full throttle.
• Trim grass and weeds by swinging the trimmer in a smooth, sweeping motion.
• Avoid hitting hard objects like rocks, fences, or concrete, as this can damage the line or the trimmer.
