If the Engine still smokes, call 1-800-DR-OWNER (376-9637) for assistance.
The Trimmer Head

The cutting Cords
are breaking. ⇒ The Cords may be too dry. Store Cords in a plastic bag with a damp sponge or cloth
to make them less prone to breaking or soak them in a bucket of water for a few
days.
⇒ Try a lighter cord.
⇒ You may be trying to do too much too fast. Ease into the material you are cutting;
let the Cord tips do the work. Take small bites of tall or tough vegetation. Cut half a
swath at a time, keeping the cut area to the discharge or right side of the Trimmer.
Go over tall material twice, the first time with the Trimmer Head tilted up and back;
the second time with the Mow-Ball™
Support on the ground.
⇒ Make sure that you are not hitting the Cords against a stone or a chain-link fence.
The Cords won’t last as long against obstacles as in the open. Work on controlling
the cutting pattern. With practice, you’ll learn to cut closer to obstacles without
hitting them.
⇒ If none of the above helps, call 1-800-DR-OWNER (376-9637) for assistance.
