OPERATING INSTRUCTIONS
TIPS FOR BEST TRIMMING RESULTS
• Keep the cutting attachment parallel to the ground.
• Cut from left to right whenever possible. Cutting to the right
improves the unit's cutting efficiency. Clippings are thrown
away from the operator.
• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon:
- Following the trimming tips
- What vegetation is being cut
- Where vegetation is being cut
DECORATIVE TRIMMING
Decorative trimming is
accomplished by removing all
vegetation around trees, posts,
fences and more. Rotate the
whole unit so that the cutting
attachment is at a 30° angle to the
ground (Fig. 10).

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 cutting head. Note positions “A”
and “B” on the cutting head.
3. Reinstall line glide plate (Fig.
7). 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. 8).
5. Pull the line and make
sure the line is against the
hub and is fully extended
through the positioning
tunnels (Fig. 9).
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
WARNING: Always wear eye, hearing, foot and
body protection to reduce the risk of injury when
operating this unit.
