OPERATION
Throttle Operation
Pull the throttle trigger toward the grip to increase
engine speed and start cutting attachment
rotation.
The trimmer has the greatest cutting force at
maximum engine speed.
Release the throttle trigger to reduce engine
speed. At idle, the cutting attachment should
coast to a stop.
Using a Nylon Cutting-Line Head
As the ends of the line wear away, more line must
be released from the cutting-line head. Your
trimmer is factory-equipped with either a manual-
feed or a semi-matic (bump feed) cutting-line
head, which have different procedures for
releasing line.
The debris shield is equipped with a cutoff knife
which automatically removes any excess line that
is released.
Manual-Feed Cutting-Line Head
Line must be released with the cutting-line head
stopped.
1. Stop the engine, and wait for the cutting-line
head to coast to a complete stop.
2. Hold the housing, pull the spool out about a
quarter of an inch, then turn the spool
counterclockwise until it snaps into the
housing again.
The spool will snap into the housing every
sixth of a turn, which releases 1 to 1-1/2
inches of line.
Semi-Matic (bump-feed) Cutting-Line Head
Line must be released with the cutting-line head
spinning rapidly.
With the engine running at full speed, tap the
cutting-line head on hard, bare ground. Do not
tap the cutting-line head on pavement or
concrete.
Each tap releases about 2 inches of line.
