MAINTENANCE AND REPAIR INSTRUCTIONS
LINE REPLACEMENT
for Hassle-Free™ Cutting Head
Always use Craftsman® Hassle-Free™ XTRA QUIET Spiral Line.
Choose the line size best suited for the job at hand. Red colored
line is designed for cutting grass and small weeds. 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. Do Not attempt to remove the cutting head
from the unit when replacing line.
1. Remove the old line and line glide
plate from the cutting head.
2. Clean entire surface of cut-ting
head. Note positions “A” and “B”
on the cutting head.
3. Reinstall line glide plate (Fig. 15).
Align arrow with:
“A” when using medium (red) or
large (black) line, or
“B” when using lines with diameters
smaller than medium (red) line
NOTE: Line glide plate must be reinstalled in cutting head before
inserting new line.
WARNING: Do not remove or alter the line cutting
blade assembly. Excessive line length will make the
clutch overheat. This may lead to serious personal injury
or damage to the unit.

Perform these required maintenance procedures at the frequency
stated in the table. These procedures should also be a part of any
seasonal tune-up.
NOTE: Some maintenance procedures may require special tools or
skills. If you are unsure about these procedures take your unit
to a Sears or other qualified service dealer.
NOTE: Maintenance, replacement, or repair of the emission control
devices and system may be performed by a Sears or other
qualified service dealer.
In order to assure peak performance of your engine, inspection of
the engine exhaust port may be necessary after 50 hours of
operation. If you notice lost RPM, poor performance or general lack
of acceleration, this service may be required. If you feel your engine
is in need of this inspection, refer service to a Sears or other qualified
service dealer for repair. DO NOT attempt to perform this process
yourself as engine damage may result from contaminants involved in
the cleaning process for the port.
4. Insert both ends of your line
through the proper holes in
the side of the cutting head
(Fig. 16).
5. Pull the line and make sure the
line is against the hub and is
fully extended through the
positioning tunnels (Fig. 17).
6. Correctly installed line will be
the same length on both
sides.
NOTE: Do not rest the Hassle-
Free™ Cutting Head on
the ground while the unit
is running.
Some line breakage will occur
from:
• Entanglement with foreign
matter
• Normal line fatigue
• Attempting to cut thick, stalky weeds
• Forcing the line into objects such as walls or fence posts
