Operating Instructions

Fuel Mixture

This unit uses a 2-cycle engine and requires a specific fuel mixture of unleaded gasoline and 2-cycle engine oil. Refer to the engine unit for the exact mixing ratio (typically 50:1 or 40:1). Use a clean fuel container and mix thoroughly before filling the fuel tank.

Starting the Engine

1. Prime the Engine: Press the primer bulb several times until fuel is visible in the clear return line.
2. Set Choke: Move the choke lever to the "FULL CHOKE" position.
3. Pull Starter Cord: Place the trimmer on a flat, stable surface. Hold the unit firmly and pull the starter cord with a smooth, steady motion until the engine attempts to start (usually 3-5 pulls).
4. Adjust Choke: Once the engine "pops" or attempts to start, move the choke lever to the "HALF CHOKE" position.
5. Restart: Pull the starter cord again until the engine starts and runs.
6. Warm-up: Allow the engine to run for 30-60 seconds to warm up, then move the choke lever to the "RUN" position.
