Setup
- Unpacking: Carefully remove all components from the packaging. Verify that all parts listed in the packing list are present.
- Handle Assembly: Attach the handle to the shaft as indicated in the assembly diagram. Ensure it is securely fastened with the provided hardware. The handle should be positioned for comfortable and balanced operation.
- Guard Assembly: Securely attach the cutting guard to the trimmer head assembly using the designated screws or bolts. This guard is crucial for operator safety and must always be in place during operation.
- Fuel Mixing and Filling:
- The SRM-3020T uses a 2-stroke engine. Mix fresh unleaded gasoline with a high-quality 2-stroke engine oil at the ratio specified in the engine manual (typically 50:1 for ECHO products).
- Use a clean, approved fuel container.
- Fill the fuel tank carefully, avoiding spills. Do not overfill. Securely replace the fuel cap.
- Loading Trimmer Line (Speed-Feed 500 Head):
- Align the eyelets on the Speed-Feed 500 head.
- Insert the appropriate diameter trimmer line (e.g., .095 Black Diamond) through one eyelet and push it through until an equal length extends from both sides.
- Twist the knob on the head to wind the line into the spool. The line will automatically feed as you twist.
Operating Instructions
Starting the Engine
- Place on Flat Surface: Place the trimmer on a flat, stable surface, ensuring the cutting head is clear of any obstructions.
- Choke Lever: Move the choke lever to the "COLD START" or "FULL CHOKE" position.
- Primer Bulb: Press the primer bulb repeatedly (typically 5-7 times) until fuel is visible in the clear return line.
- Pull Starter Cord: Grip the starter handle firmly and pull the starter cord with a smooth, steady motion until the engine fires (usually 1-3 pulls). Do not pull the cord to its full extension.
- Choke to Half: Once the engine fires, immediately move the choke lever to the "HALF CHOKE" position.
- Restart: Pull the starter cord again until the engine starts and runs smoothly.
- Choke Off: Once the engine is running, move the choke lever to the "RUN" or "OFF CHOKE" position. Allow the engine to warm up for 30-60 seconds before operating.
Operating the Trimmer
- Proper Grip: Hold the trimmer firmly with both hands, maintaining a balanced stance.
- Cutting Technique:
- Use a sweeping motion, moving the cutting head from side to side.
- For best results, cut with the tip of the line.
- Avoid hitting hard objects like rocks, fences, or concrete, as this can damage the line and the trimmer.
- Line Advancement: The Speed-Feed 500 head allows for quick line advancement by tapping the head on the ground while the engine is running at full throttle.
- Fuel Monitoring: Periodically check the fuel level. Refuel only when the engine is off and cool.
Stopping the Engine
- Release the throttle trigger.
- Move the engine stop switch to the "OFF" position.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your ECHO SRM-3020T string trimmer.
- Air Filter Cleaning:
- The two-stage air filtration system increases cleaning capability and allows for longer maintenance intervals.
- Access the air filter by opening the tool-less access cover.
- Clean the filter element with warm, soapy water, rinse thoroughly, and allow to air dry completely. Replace if damaged or excessively dirty.
- Spark Plug Inspection:
- Remove the spark plug and inspect for carbon buildup or wear.
- Clean or replace as necessary. Ensure the gap is set correctly according to the engine manual.
- Fuel Filter: Inspect and replace the fuel filter periodically, especially if you notice fuel delivery issues.
- Gearbox Lubrication: Refer to your engine manual for specific instructions on lubricating the gearbox. This typically involves adding grease to a designated port.
- Trimmer Head and Line:
- Regularly inspect the Speed-Feed 500 head for wear or damage.
- Replace trimmer line as needed. Use only recommended line diameters (e.g., .095 Black Diamond).
- General Cleaning: Keep the engine cooling fins and air intake clear of debris to prevent overheating. Wipe down the exterior of the trimmer after each use.
