TRIMMER
Always
observe safety rules when perform-
ing any maintenance.
TIRES
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm rubber.
• 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. Use .155 inch diameter trimmer
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
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 18-3/4 inches 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
the "22" mark (your unit's width of cut).
TO REPLACE TRIMMER LINE
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with spark plug.
2. Remove worn trimmer line from line
carrier plate.
3. Fold new, cut to length, trimmer line in
half and insert folded end through
carrier plate opening to back side of
retainer clip.
4. With folded end of line at back side of
retainer clip, pull line outward until
line is fully seated under the retainer
clip.
5. Repeat on other side of carrier plate.
6. Check all lines to be sure they are the
same length.
7. Reconnect spark plug wire to spark
plug.
