Operating Instructions
Follow these steps for safe and effective operation of your string trimmer.
1. Starting the Engine (Easy Start Technology)
- Prime: Press the primer bulb several times until fuel is visible.
- Choke: Move the choke lever to the FULL CHOKE position.
- Pull: Pull the starter rope firmly and smoothly until the engine attempts to start (usually 1-3 pulls).
- Once the engine attempts to start, move the choke lever to the HALF CHOKE position.
- Pull the starter rope again until the engine starts.
- Allow the engine to warm up for a few seconds, then move the choke lever to the RUN position.
2. Trimming Technique
Hold the trimmer firmly with both hands. Maintain a balanced stance. Use a sweeping motion to cut grass and weeds. The straight shaft design provides a clear view of the trimming area. The 17-inch cutting width allows for efficient coverage.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your trimmer.
1. Trimmer Line Replacement
The bump feed trimmer head uses 0.095" twisted line. To replace the line:
- Ensure the engine is off and cool.
- Locate the bump cap on the trimmer head.
- To remove the bump cap, turn it clockwise for this model (WS205). If the cap is difficult to remove, applying penetrating oil and allowing it to soak may help.
- Remove the old line spool.
- Install a new spool of 0.095" twisted trimmer line, ensuring it is wound correctly according to the head's markings.
- Reattach the bump cap by turning it counter-clockwise until secure. Do not overtighten.
2. General Cleaning and Storage
After each use, clean the trimmer housing and cutting head to remove grass clippings and debris. Store the trimmer in a dry, well-ventilated area, away from direct sunlight and extreme temperatures. For long-term storage, drain the fuel tank or use a fuel stabilizer.
Troubleshooting
This section addresses common issues you might encounter with your CRAFTSMAN WS205 trimmer.
Engine Does Not Start
- Check Fuel: Ensure the fuel tank contains the correct 40:1 gasoline/oil mixture.
- Primer Bulb: Verify the primer bulb is pressed until fuel is visible.
- Choke Position: Confirm the choke is in the correct position for starting (FULL CHOKE, then HALF CHOKE).
- Spark Plug: Inspect the spark plug for fouling or damage. Clean or replace if necessary.

Trimmer Line Does Not Feed

- Bump Cap Issue: Ensure the bump cap is securely attached but not overtightened, allowing the bump mechanism to function.
Engine Stops During Operation
