1 PART OIL TO 40 PARTS GASOLINE=
3.2 ft. oz. oil to i gallon gasoline
8.0 ft. oz. oil to 2.5 gallon gasoline
Not all air cooled 2-cycle engine oils have the

If SEARS CRAFI'SMAN
2-_cle

quality, 2-cycle
engine oil recommended
for
air-cooled engines. Mix at a ratio of 16:1 (8 oz.
oil to I gallon gasoline). A 16:1 fuet mixture with
these oils will assure adequate lubrication for

a. Use only recommended
fuel mixtures.
b. Mix and pour fuel outdoors

there are no sparks or flames.
c. Use a container

A CAUTION
Experience
indicates
that alcohol blended fuels

can attract moisturewhich
leads to separation

of acids during storage.
Acidic

the fuel system of an engine
while in storage.
To avoid engine problems,
do
not leave fuel in the unit when storing for 30
days or longer.
Start the engineand

:in
:::
:
Oil--National
Association
• AUTOMOTIVE
OIL-Does not have proper additives for air-cooled0
2-cycle engines and can cause engine damage.
e. Your unit is powered
by a 2-cycle
engine
which requires a fuel mixture
of regular
unleaded
gas?!ine and a high quality engine oil spemally made for 2-cycle,
air
cooled engines.
The internal design of the
2-cycle engine requires lubrication of moving
parts. Lubrication is provided when the recommended mixture of gasoline and oil is used.
b. Genuine Sears 40:1, 2-cycle
engine oil is
strongly
recommended
for the protection
of your unit. Extensive englneeringtests
have
proven that Sears 2-cycle
engine oil resists
break-down
at operating temperatures common to 2-cycle engines, resulting in dependable performance and longer engine life.
c. Gasoline must be clean and not over two
months
old. After a short period of time,
gasoline wilt chemically break down and form
compounds thatcausehard starting and dami age m 2-cycle engines.
d. The correct measure
of gasoline to oil is
very important.
Too much oil in the mixture
will foul the spark plug.
_
Too little oil or incorrect
oil
_iwill cause engine to overheat
and seize.
e_i:_
Always mi_ the fuel thoroughly
in a con: ii tainer since gasoline and oil do not readily
::: combine. Do not mix gasoline and oil directly

NOTE__:Always tap the trimmer head on a grassy
area. Tapping on surfaces such as concrete or
asphalt can cause excessive wear to the trimmer head.

The line will easily remove grass and weeds
from around
walls, fences, trees and flower
beds, but it also can cut the tender bark of

If the line is worn down to two
