method for replacing line and ensuring opti-
mum performance.

Replacement spools are color--coded to en-
sure use of the correct spool with your unit.
Be sure to use the same color spool as the
existing spool.

Always clear dirt and debris from
cutting head components when performing
any type of maintenance.

strip from line and spool.
REFILLING THE SPOOL WITH LINE
WARNING:
Use only 0.080” (2 mm)
diameter round line.
Other sizes and shapes
of line will not advance properly and will result in
improper cutting head function or can cause se-
rious injury. Do not use other materials such as
wire, string, rope, etc. Wire can break off during
cutting and become a dangerous missile that
can cause serious injury.

ameter round WEED EATER brand line.
