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.
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.
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 III™ 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
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).
WARNING:
Before you begin using any
attachment, read and understand the manual that
came with the attachment. Follow all safety
information contained within.
