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.

counterclockwise to tighten. Turn “RH” stud clockwise to tighten.

When spacer is properly matched and installed, there should be no gap between spacer and base

plate on gearcase.

clockwise. Hand-tighten only.
