manual for engine-specific
procedures.
Verify throttle is in RUN position when engine is warm.
Verify throttle cable is attached to engine and moves freely.
Inspect air filter intake for clogging.
Verify engine blower house, throttle linkage and cooling fins are free of debris.
Clean as necessary.

Cutting cords breaking
Store cords in a plastic bag with a damp sponge or cloth to make them more pli-
able or store them in a bucket of water for a few days.
Cutting too fast. Ease into the material. 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 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
®
on the
ground.
Cords striking a stone, chain-link fence, or other obstacle. Approach hard obsta-
cles slowly and avoid contact.
Quick-Lock™ head is wear-
ing too quickly
Avoid pushing the trimmer head down into the ground. The trimmer/mower works
best with the Mow-Ball
®
resting easily on the ground or slightly raised.
The Mow-Ball
®
is striking rocks, concrete driveways or other hard obstacles.
Approach hard obstacles slowly and avoid contact.
