OPERATION
ADVANCING LINE
This trimmer uses a line advance system which requires the operator to tap or bump the trimmer
head on the grass while running the engine at full throttle.
■ Run the engine at full throttle.
■ Tap the trimmer head on the ground to advance the line. With each tap, the line advances
further. A firm but gentle motion should be used when tapping the line on the ground (Fig. 20).
DO NOT keep the trimmer head pressed against the ground.
NOTICE: The cutting blade on the underside of the debris guard will cut the line to the correct
length.
NOTICE: Line that is too short may not advance using the tapping method and may need to be
done manually.
To advance the cutting line manually:
■ Stop the engine completely.
■ Push the spool cover in while pulling on the line, until you reach the desired length.
NOTE: After each use, clean the trimmer head with a damp cloth to remove dirt and grime.
CUTTING BLADE
The trimming line cutting blade is attached to the underside of the debris guard (Fig. 21).
The cutting blade trims the line at a length that yields optimum cutting results. If the engine is
running faster than normal, or it appears as though the trimmer is less efficient, advance the line.
This will maintain proper performance and keep the line long enough to efficiently cut the grass.
