BEFORE STARTING ENGINE
FUELING
This engine is certified to operate on
unleaded gasoline intended for
automotive use.
This is a 2-cycle engine product and
requires pre-mixing gasoline and 2-
cycle oil. For normal homeowner use,
we recommend mixing fuel in a 1 or 2
gallon container approved for gasoline.
Use Craftsman®2=cycle engine oll No.
36549. Mix at the ratio of 40:1 (3.2 oz.
of oil to 1 gal. of gasoline).
Oil formulated for 50:1 should be mixed at
a 40:1 ratio.
Oil formulated at 100:1,24:1, 16:1 or non
2-cycle oil should not be used. They can
cause smoking, oily residues, spark plug
fouling, combustion chamber deposits,
hard starting, etc.; and may void your
warranty.
Do not use automotive oil or 2-cycle
outboard oil.
1. Loosen fuel cap slowly. Rest the cap
on a clean surface.
2. Carefully pour fuel into the tank. Avoid
spillage.
3. Immediately replace fuel cap and
hand tighten. Wipe up any fuel
spillage.
4. It is normal for smoke to be emitted
from a new engine after first use.
NOTE: Always shut off engine before
fueling. Never add fuel to a machine
with a running or hot engine. Move at
least 10 feet (3m) from refueling site
before starting engine. DO NOT
SMOKE!
_, WARNING
Experience indicates that atcohol blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which
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, the
fuel system should be emptied before
storage for 30 days or longer. Start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
next season. See Storage instructions for
additional information. Never use engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.
IMPORTANT
ALWAYS OPERATE TRIMMER AT FULL
THROTTLE. PROLONGED PART
THROTTLE CUTTING WILL RESULT IN
OIL DRIPPING FROM THE MUFFLER.
Cut tall grass from the top down. This
will prevent grass from wrapping
around the drive shaft housing and
stringhead that may cause damage
from overheating. If grass becomes
wrapped around the stringhead, STOP
THE ENGINE, disconnect the spark
plug wire, and remove the grass.
String advance is controlled by tapping
stringhead on grass while running engine
at full throttle.
NOTE:
This trimmer is equipped with a cut-
off blade on the grass deflector. For
best cutting, advance string until it is
trimmed to length by the cut-off blade.
Advance string whenever you hear the
engine running faster than normal.
This will maintain best performance
and keep string long enough to
advance properly,
If the string is worn too short you may
not be able to advance the string by
tapping, If so, STOP THE ENGINE, and
manually advance per instructions on
page 9, item 7.
Keep the trimmer tilted toward the area
being cut. See illustration for best cutting
area (A). Do not cut in dangerous
cutting area (B).
Use the tip of string to do the cutting -
do not force stringhead into uncut grass.
Wire and picket fences cause extra string
wear, even breakage. Stone and brick
walls, curbs, and wood may wear string
rapidly. Walk around trees and shrubs.
Tree bark can easily be damaged by the
string.
