M18 FUEL™ String Trimmer w/ QUIK-LOK™ Kit

Power & Motor

•Uses a POWERSTATE™ brushless motor, giving it performance that Milwaukee says is more powerful than a 31 cc gas trimmer.  

•Max speed up to 6,200 RPM.  

•Reaches full throttle in under 1 second, thanks to REDLINK PLUS™ electronics.  

Battery & Run-Time

•Comes with a M18 REDLITHIUM HIGH OUTPUT XC 8.0 Battery (in the kit) for longer runtime.  

•Uses REDLINK PLUS™ intelligence — this helps protect the battery and tool from overload, overheating, and over-discharge.  

Design & Usability

•Designed in two main parts: the M18 FUEL Power Head w/ QUIK-LOK, and a QUIK-LOK String Trimmer Attachment.  

•QUIK-LOK system lets you swap the power head to different attachments (there are about 13 compatible ones), reducing the need for separate motors.  

•Balanced design (motor in the rear) improves control and reduces fatigue.  

•Variable-speed trigger plus three speed settings for better control.  

Cutting & Line

•Cutting swath is 14″ to 16″, depending on how you set it.  

•Supports two line diameters: 0.080″ and 0.095″.  

•Features Milwaukee’s Easy Load Trimmer Head — you can load up to 25 ft of line in under 30 seconds.  

Durability & Cooling

•Has an advanced air-cooling system to sustain high power during demanding tasks.  

•Built with professional/landscaper-level robustness.  

Weight & Dimensions

•Total weight around 12.3 lb with the kit (tool + battery + attachment).  

•Length: ~ 74 in long (when assembled) per some spec sheets.  

Compatibility

•Part of the M18 system, meaning this power head is compatible with other M18 tools.  

•QUIK-LOK power head works with many compatible attachments (edger, pole saw, hedge trimmer, etc.).  

Safety & Control

•REDLINK PLUS electronics give “instant throttle response.”  

•Variable trigger helps for “feathering” the speed, not just full power or nothing.  

Warranty

•Comes with a 3-year limited warranty for the tool.

Pros & Considerations

Pros:

•Very powerful for a battery trimmer.

•Swappable head via QUIK-LOK system — offers flexibility and saves cost.

•Good runtime with the included 8.0 Ah battery.

•Easy line reloading.

•Balanced design makes for better ergonomics.

Considerations / Possible Drawbacks:

•Because it’s a professional-level tool, it’s fairly heavy (~12.3 lb).

•QUIK-LOK system requires you to buy compatible attachments if you want more functionality.

•Some users on forums mention potential vibration issues or battery contact problems. > “the joint … feels secure … I personally didn’t feel any play …”  

•Good performance depends a lot on battery — using smaller batteries may reduce runtime or increase heat.
