TRIMMER
Always observe safety rules when per-
forming any maintenance.
TIRES
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm rub-
ber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
TRIMMER LINE
For best results, replace trimmer lines
when they have worn to half their original
length.
20" models use .130 inch diameter trim-
mer line. Cut new trimmer line length to
16-3/4 inches.
22" models use .155 inch diameter trim-
mer line. Cut new trimmer line length to
18-3/4 inches.
After new line is installed on trimmer head,
check all lines so they do not vary more
then one (1) inch in length. This is im-
portant to make sure the trimmer head is
balanced and will not vibrate abnormally.
AWARNING: Use only the specified
trimmer line. Do not use other materials
such as wire, string, rope, etc. Wire can
break off during trimming and become a
dangerous missile that can cause serious
injury.
TO CUT LINE TO PROPER LENGTH
NOTE: Trimmer line pre-cut to proper
length is available for this unit; see the
Repair Parts section of this manual.
If trimmer line is purchased in bulk, it must
be cut to length before using. Use the
built-in length guage as follows:
1. From front of trimmer, place the end of
spooled trimmer line at the mark on the
side of the debris shield as shown.
2. Wrap trimmer line around front of chas-
sis cover to other side and cut at the
mark (for your unit's width of cut).
