USE CORRECTDIAMETER
TRIMMER LINE
Fortougher cutting conditions, use two
(or four) sections of thethicker gauge,
.155"diameter extra-heavyduty line.
Forless demandingconditions, usetwo
sections of thethinner gauge,.130"diam-
eter heavy-duty line.
Thethicker line hasthe heft to chop
through tougher materials, while the
thinner line provides a more precise cut.
To changetrimmer lines, refer to
ChangingTrimmer Lines in Section5.
NOTE:Thethinner line is also recom-
mendedfor use neartrees or shrubs to
help preventgirdling (cutting the bark).

Tips for Precision Cutting
Forthe most precisecutting possible,
selectthe appropriateline cutting height
and trimmer line size (thickness) for the
conditions.
Whenmowing, letthe cutting head rest
lightly on theground and do not lift up or
push down on the handlebars.This
allows the cutting headto follow the
ground contour closely, resulting in the
most evencut possible. Also, besure to
easeinto heavygrowth to prevent over-
whelming the machine.
