INSPECT MUFFLER AND SPARK
ARRESTING SCREEN
As the unit is used, carbon deposits
build up on the muffler and spark ar-
resting screen. For normal homeown-
er use, however, the muffler and spark
arresting screen will not require any
service. After 50 hours of use, we rec-
ommend that your muffler and spark
arresting screen be serviced or re-
placed by a Sears Service Center.
REPLACE SPARK PLUG
Replace the spark plug each year to
ensure the engine starts easier and
runs better. Set spark plug gap at
0.025 inch. Ignition timing is fixed and
nonadjustable.
1. Twist, then pull off spark plug boot.
2. Remove spark plug from cylinder
and discard.
3. Replace with Champion RDJ-7Y
spark plug and tighten securely
with a 5/8 inch (15 mm) socket
wrench.
4. Reinstall the spark plug boot.
LINE REPLACEMENT
• Always use Craftsman replacement
line.
Choose the line size best suited for
the job at hand. Red line is designed
for cutting grass and small weeds.
The black colored line is designed for
cutting larger weeds and light brush.
NOTE: Before inserting new line into
the holes in the cutting head, identify
the proper holes. Follow directions as
shown on the line glide plate.
1. Remove the old line and line glide
plate from the cutting head.
2. Clean entire surface of cutting head.

lustration). Align arrow with:

CARBURETOR ADJUSTMENT
Adjusting the carburetor is a compli-
cated task. Carburetor adjustment is
critical and if done improperly can per-
manently damage the engine as well as
the carburetor. We recommend that you
take your unit to a Sears Service Center
for any necessary adjustments.
