Trimmer Head Installation

1.	Insert locking tool (A) into gear case to lock output shaft (B). Remove existing cutting attachment (C) from unit
	following manufacturer’s instructions.
	IMPORTANT: Your unit must be equipped with a debris shield including a line cutter that will cut line to length
	when trimmer line is advanced.
2.	Install or reuse unit manufacturer’s gear case base plate (D). Base plate must support trimmer head and allow it
	to rotate freely.
3.	Select and Install Mounting Hardware
	Use the Speed-Feed®Application Chart provided to identify the bushing or bushing and mounting stud
	combination needed for your model.
	IMPORTANT: For Echo SRM units only. Check debris shield on unit for “R” mark between cutoff blade

screws.
a.	Units with “R” mark – Echo line head will fit on unit as is - go to Step 6.
b.	Units without “R” mark – Remove short bushing (E) from Echo line head and replace with long
	bushing (J) and use spacer (M).

NOTE: If your brand or model number is not listed, match the existing mounting hardware from your model with Echo mounting studs and/or bushings to determine the correct parts needed. If you need help, visit www. echo-usa.com, or call the Consumer Product Support Department at 1-800-432-3246 from 8:30 am to 4:30 pm (Central Time) Monday through Friday.

NOTE: Gold bushing (E) (used with LH1, LH2, LH6) is preinstalled in trimmer head. Black bushing (N) (used with RH 1 and RH 2) is preinstalled in white core (P). If required, depress locking tabs (T), and open trimmer head (K) to install new parts. Reassemble trimmer head in reverse order of disassembly. Make sure “L” mark is facing away from bushing when replacing spool fir LH units. Make sure “R” mark is facing away from bushing for RH units. Trimmer head halves will snap together tightly only if parts are properly assembled.

4.If required, install new mounting stud into threaded hole in gear case output shaft (B). Turn “LH” studs counterclockwise to tighten. Turn “RH” stud clockwise to tighten.

5.If required, place reversible spacer (M) on base plate of gearcase, matching spacer recess to pilot diameter of base plate.

NOTE: When spacer is properly matched and installed, there should be no gap between spacer and base plate on gearcase.

6.Attach New Trimmer Head (K)

Thread LH trimmer head counterclockwise on to mounting stud or output shaft. Thread RH trimmer head on clockwise. Hand-tighten only.

Echo SRM Only NOTE: There should be no gap between spacer and line head after tightening.

IMPORTANT: Do not force, otherwise threads will strip and cause permanent damage. Unscrew and confirm correct thread size.

7.Remove locking tool (A) from gear case.

8.If necessary, cut trimmer lines so length does not extend beyond the cut-off blade on debris shield.

Operation

1. To feed trimmer line, bump bottom of trimmer head against ground while running at normal operating speed.
