abuse or negligence. To receive full value
from the warranty, operator must maintain
trimmer as instructed in this manual.
Some adjustments will need to be made
periodically to properly maintain your unit.
All adjustments in the Service and Adjust-
ments section of this manual should be

Always observe safety rules when per-
form ing any main te nance.
TIRES
• Keep tires free of gasoline, oil, or insect
control chemi cals 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
important to make sure the trimmer head
is balanced and will not vibrate ab nor-
mal ly.
WARNING:
Use only the specified
trimmer line. Do not use other ma te ri als
such as wire, string, rope, etc. Wire can
break off during trimming and become a
dan ger ous 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
chassis cover to other side and cut at
