control lever.
Þ Is the brake pad worn? Drop the bearing housing
according to the procedure in the maintenance
section of this manual and check the pad for
wear. Also make sure the spring is not broken,
missing or stretched.
Þ If the head keeps spinning when you release the
bail bar, see "To Adjust the Belt Tension through
the Trimmer Control Cable" on page 28.
Þ If none of the above works, call 1(800)DR-
OWNER(376-9637) for advice and assistance.
Cutting cords are breaking Þ Are your cords 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.
Þ Are you trying to do too much too fast? Ease into
material to be cut; 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 DR
®
. Go over tall
material twice, the first time with the head tilted
up and back, the second time with the Mow-
Ball
ä Support on the ground.
Þ Try a lighter cord.
Þ Are you hitting your cords against a stone or a
chain-link fence? The cords just won’t last as
long as in the open. Work on controlling the
cutting pattern; with practice you’ll learn to cut
closer to obstacles without hitting them.
Cutting cords are pulling out Þ Are you moving too fast into tough, woody
growth? If so, cords may wrap on stalks and pull
out. Check the operating tips in the section on
breaking cords above.
Þ Are you trying to cut material too heavy for the
cord? The DR
®
is designed to cut green material
up to about the thickness of a pencil. For very
heavy material, you may need the BEAVER
BLADE
®
attachment.
Þ Are you installing the smaller cord in the larger
openings?
Parallel Trimming Action is difficult Þ Is the axle binding when you shift into PTAä
mode? Spray some FLUID FILM
®
at the points
where the axle slides on the frame.
Þ Is the self-locking nut over the bolt that holds the
flat end of the PTA
ä lever to the latch too tight?
If so, loosen it 1/4 turn at a time until the PTA
ä
works smoothly.
Þ Is the axle nut under the frame too tight? If so,
loosen it a bit.
Þ If you still have trouble engaging the PTAä
feature, call 1(800)DR-OWNER(376-9637) for
advice and assistance.
