Why won't the trimmer head advance line on my Ego Power+ STA1500?

  Melissa FowlerAug 19, 2025
  If the trimmer head on your Ego Power+ Trimmer won't advance the line, there could be several reasons. First, stop the trimmer, remove the battery, and clean the motor shaft and trimmer head of any grass. If there's not enough line on the spool, remove the battery and replace the cutting line, following the 'LINE REPLACEMENT' section in this manual. A dirty trimmer head can also cause issues; remove the battery and clean the spool, lower cover assembly, and upper cover. If the line is tangled, remove the battery, take the line off the spool, and rewind it, referring to the 'RELOAD THE CUTTING LINE' section in this manual. Lastly, if the line is too short, remove the battery and manually pull the lines while alternately pressing down and releasing the trimmer head.

  If your Ego Power+ Trimmer fails to start, make sure the battery pack is correctly attached to the power head. If it is, remove the battery and check the contacts, then reinstall the battery pack until it snaps into place to ensure proper electrical contact. A depleted battery can also prevent starting; charge it using the EGO chargers listed in this manual. Finally, ensure you are pressing down the lock-off lever and holding it while simultaneously depressing the trigger to turn on the line trimmer.

  To prevent grass from wrapping around the trimmer head and motor housing of your Ego Power+ Trimmer, avoid cutting tall grass at ground level. Instead, cut tall grass from the top down, removing no more than 20 cm in each pass.

  If the blade on your Ego Power+ Trimmer isn't cutting the line, it's likely that the line-cutting blade on the edge of the guard has become dull. Sharpen the blade with a file or replace it with a new one.

The EGO STA1500 is a line trimmer attachment designed for use with the EGO 56V Lithium-Ion Power Head PH1400E. This attachment is intended for trimming grass and weeds around porches, fences, and decks.

Function Description:

The line trimmer attachment utilizes a bump head cutting mechanism with a 2.4 mm nylon twist line to cut grass and weeds. The design allows for the release of additional cutting line without stopping the motor by lightly tapping the trimmer head on the ground during operation. The attachment is designed for efficient and safe operation when connected to a compatible EGO power head.

Important Technical Specifications:

Cutting Mechanism: Bump Head
Line Diameter: 2.4 mm nylon twist line
Cutting Width: 38 cm
No-Load Speed: 5000/6000 min⁻¹
Weight (Without battery pack): 1.59 kg
Recommended Operating Temperature: 0°C–40°C
Recommended Storage Temperature: -20°C–70°C
Sound Pressure Level: 70 dB(A)
Compatibility: For use only with the 56V Lithium-Ion Power Head PH1400E.

Usage Features:

Assembly: The guard is mounted onto the shaft base using two screws and spring washers. The line trimmer attachment connects to the power head as described in the PH1400E operator's manual.
Starting/Stopping: Refer to the "STARTING/STOPPING THE POWER HEAD" section in the PH1400E operator's manual for instructions.
Adjusting Cutting Line Length: Line can be released by lightly tapping the trimmer head on the ground while operating. If the line becomes too short or breaks, it can be reloaded by following the "LINE REPLACEMENT" instructions.
Line Replacement:
1. Remove the battery pack.
2. Remove any remaining cutting line.
3. Cut 5m of new cutting line (about 5 times the length of the trimmer aluminum shaft).
4. Insert the line into the mounting hole inside the eyelet. Push and pull until equal amounts of line appear on both sides.
5. Press and rotate the lower cover assembly in the arrow direction to wind the line onto the spool until approximately 14cm of line is showing on each side.
6. Push the lower cover assembly down while pulling on the lines to manually advance the line and check for proper assembly.
- If the cutting line breaks from the line outlet or doesn't release, remove the battery pack, press the release tabs on the upper cover, and remove the lower cover assembly. Then, re-insert the line and reassemble.
3-Teeth Blade Replacement (if applicable):
1. Remove the lower cover assembly.
2. Insert the stabilizer and use an impact socket wrench to loosen the nut.
3. Remove all parts except the inner flange and nut.
4. Mount the blade onto the motor shaft.
5. Tighten the blade.
Safety Precautions:
- Always wear eye protection, hearing protection, heavy long pants, boots, and gloves.
- Clear the work area of children, bystanders, and pets (at least 15m away).
- Do not operate the machine while tired, ill, or under the influence of drugs or alcohol.
- Ensure the guard is firmly in place.
- Do not use metal-reinforced line, wire, or rope.
- Maintain proper footing and balance.
- Do not overreach.
- Stop the motor and cutting unit if approached.
- The shoulder strap acts as a quick-release mechanism in hazardous situations.
Environmental Protection: Do not dispose of electrical appliances as unsorted municipal waste. Use separate collection facilities.

Maintenance Features:

General Maintenance:
- Before inspecting, cleaning, or servicing, stop the motor, wait for all moving parts to stop, and remove the battery pack.
- Clear any grass wrapped around the motor shaft or trimmer head.
- Use a small brush or vacuum cleaner to clean air vents.
- Clean the unit with a damp cloth and mild detergent.
- Avoid strong detergents or solvents on plastic parts.
- Periodically sharpen or replace the line-cutting blade on the guard.
Transmission Gears Lubrication:
- Check the gear case grease level approximately every 50 hours of operation by removing the sealing screw.
- If no grease is visible, hold the line trimmer on its side with the sealing screw facing upwards.
- Use the multi-function wrench to loosen and remove the sealing screw.
- Inject grease (up to 3/4 capacity) into the screw hole using a grease syringe (not included).
- Tighten the sealing screw.
Storage:
- Remove the battery pack.
- Clean the tool thoroughly.
- If stored separately from the power head, fit the end cap on the attachment shaft to prevent dirt from entering the coupler.
- Store in a dry, well-ventilated, locked-up area, out of reach of children.
- Do not store near fertilizers, petrol, or other chemicals.
