ENGINE INFORMATION
A. FUELING YOUR ENGINE
1.FUEL SAFETY
a. Use only recommended fuel mixtures.
b. Mix and pour fuel outdoors and where
there are no sparks or flames.
c. Use a container approved for fuel.
d. Do not smoke or allow smoking near fuel
or the unit or while using the unit.
e. Wipe up all fuel spills before starting the
engine.
£ Move at least 10 feet (3 meters) away
from fueling site before starting engine.
g. Stop engine before removing fuel cap.
Allow engine to cool before refueling.
h. Before storing the unit, use up fuel left in
..... the fuel lines and carburetor by starting the
engine and letting it _.Jn until it stops.
i. Store unit and fuel m an area where fuel
vapors cannot reach sparks or open
flames from water heaters, electric motors or
switches, furnaces, etc.
2. FUEL MIXTURE
e. Your unit is powered by a 2-cycle engine
which requires a fuel mixture of regular
unleaded gas?!ine and a high quality en-
gine 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 rec-
ommended 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 com-
mon to 2-cycle engines, resulting in depend-
able 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 dam-
i 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
: ::: :in t_ _l _k" r
3. USE THE FOLLOWING:
SEARS CRAFTSMAN 2-cycle engine oil _ed
at 40:1 is strongly recommended_ Consult the
instructions on oil container for proper mixing.
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
same qualities. If SEARS CRAFI'SMAN
2-_cle engine_ oil is not available, use a good
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
.....yourengine.
4. DO NOT USE:
NMM Oil--National Marine Manufac-
turers Association (formerly BIA oil)--
AUTOMOTIVE OIL--
Does not have proper additives for air-cooled0
2-cycle engines and can cause engine damage.
..... A CAUTION
Experience indicates that alcohol blended fuels
(tailed gasohol or using ethanol or methanol)
can attract moisturewhich leads to separation
and formation of acids during storage. Acidic
gas can damage 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 let it run
until the fuel lines and carburetor are empty.
Use fresh fuel next season. See the "Storage"
section for additional information. Never use
engine or carburetor cleaner products in the
fuel tank or permanent damage can occur.
5. HOW TO MIX FIlL AND FILL TANK
a.: Pour the proper measure of engine oil into an
approved, marked container. Then, flU the
container with regular unleaded gasoline.
NOTE: If fuel is alreadyin the container, add the
::, :: proper measure of engine oil. Then, close the
container tightly and shake it momentarily.
NOTE: Do not mix gasoline and oil directly in the
:: fuel tank.
b. Using a spout or funnel, fill the fuel tank with
.... fuel mix.
c. 1_ the fuel caps securely.

B. TRIMMER LINE ADVANCE
The trimmer line will advance approxi-
mately 2 inches each time the bottom oft.he
trimmer head is tapped on the ground with
theengine running at full throttle.
The most efficient llne length is the maxi-
mum length allowed by the line limiter.
Always keep the shield in place when the
tool zs being operated. Figure 10.
To Advance Line:
1. Operate the engine at fu!l throttle.
2. Hold the trimmer head pamllet to and above
3. Tap the bottom of the trimmer head lightly on
the ground one time. See Figure 10. Approxi-
mately 2 inches of line will be advancedwith
each tap.
NOTE__:Always tap the trimmer head on a grassy
area. Tapping on surfaces such as concrete or
asphalt can cause excessive wear to the trim-
mer head.
NOTE: If the line is worn down to two
inches or less, more than one tap win be re-
quired to obtain the most efficient line length.
C. CUTTING METHODS
A WARNING [
Use _um speed and do not crowd the line[
when cutting around hard objects (rock, gravel, J
fenceposts, etc), which can damage the trimmerl
head, become entangled in the line, or be[
thrown causing a serious hazard. J
The tip of the line does the cutting. You will
achieve the best performance and minimum line
wear by not crowding the Hne into the cutting
area. The right and wrong ways axe shown in Fig-
ure 11.
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
trees or shrubs and scar fences. To help avoid
damage especia_y to delicate vegetation or trees
with tender bark, shorten line to 4-5 inches and
use at less than _ throttle.
For trimming or scalping, use less than full
throttle to increase line life and decrease
head wear, especially:
- during light duty cutting.
- near objects around which the line can wrap
such as small posts, trees or fence wire.
A WARNING
Useoonly,080" diameter line. Other sizes of line
wiI1 not advance properly and can cause serious
injury. Do not use other materials such as wire,
string, rope, etc. Wire can break off during cut-
ring and become a dangerous missile that can
cause serious injury.
