cutting head components when performing
any type of maintenance.

Use a pre- -wound spool or refill spool with
line. If using a pre- -wound spool, remove tape
strip from line and spool.

REFILLING THE SPOOL WITH LINE

Use only 2 mm diameter
round line. Other sizes and shapes of line will
not advance properly and will result in improp-
er cutting head function or can cause serious
injury. Do not use other materials such as
wire, string, rope, etc. Wire can break off dur-
ing cutting and become a dangerous missile
that can cause serious injury.
1. Cut a length of 8 meters of 2 mm diameter
round Partner® brand line.

direction
shown on
spool.

justments. Keep all parts of your body away
from the cutting attachment and muffler.
