LINE REPLACEMENT
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
cutting head. Note
positions "A" and "B" on
the cutting head.
3.
Reinstall line glide plate
(Fig. 10). 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.
4.
Insert both ends of your line through the proper holes in the
side of the cutting head (Fig. 11).
5.
Pull the line and make sure the line is against the hub and is
fully extended through the positioning tunnels (Fig. 12).
6.
Correctly installed line will be the same length on both sides.
NOTE: Make sure that when installing new line, that the line is as
close to even as possible. Any variation in lengths may
cause the unit to vibrate excessively. If this happens, stop
the unit and make sure the line is even.
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
NOTE: During normal use the trimming line may become worn
unevenly which may cause excessive vibrations in the unit.
If this becomes uncomfortable or uncontrollable, stop the
unit and replace the line. Refer to the Line Replacement
instructions above.
