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.
_,WARNING:
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.

LINE
1. Disconnect
spark plug wire from spark
plug and place wire where it cannot
come in contact with spark plug.
2. Hemove 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.

retainer clip, pull line outward until
line is fully seated under the retainer
clip.

NOTE:
Although
multi-viscosity
oils
(5W30, 10W30 etc.) improve starting in
cold weather,
these multi-viscosity
oils
will result in increased
oil consumption
when used above 32°F. Check your
engine oil level more frequently
to avoid
possible
engine damage
from running
low on oil.
Change the oil after every 25 hours of
operation
or at least once a year if the
lawn mower is not used for 25 hours in
one year.
Check the crankcase
oil level before
starting the engine and after each five (5)
hours of continuous
use. Tighten oil plug
securely
each time you check the oil
level.
