DR Power Sprint (2000 - 2004) - Manual (Page 29)

DR ® TRIMMER/MOWER ™ Safety & Operating Instructions 23
Trimmer head keeps
spinning or spins when
bail bar is released
⇒ Is your v-belt properly aligned? Check it against the figures in the Belt
section on page 18.
⇒ If the head keeps spinning when you release the bail bar, see "To Adjust
the Belt Tension through the Trimmer Control Cable" on page 20.
⇒ If none of the above works, call 1(800)DR-OWNER(376-9637) for advice
and assistance.
Cutting cords are
breaking
⇒ Are your cords 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.
⇒ 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  Support on the ground.
⇒ 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 ⇒ 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.
⇒ 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.
⇒ Are you installing the smaller (130 mil) cord in the larger (155 mil) cord
slots?
Parallel Trimming
Action is difficult ⇒ Have you adjusted the handlebar up or down? If so, you may need to
adjust the PTA Lever. See page 21.
Mow-Ball  Support is
wearing too quickly
⇒ Are you pushing the trimmer head down into the ground? The DR ®
TRIMMER/MOWER  works best with a light touch, with the Mow-Ball
Support resting easily on the ground.
⇒ Are you hitting the Mow-Ball Support against rocks, concrete driveways
or other hard obstacles? Try approaching them slowly, and from different
directions, to avoid unnecessary wear.
⇒ Are you trimming in sand or other abrasive soils? The aluminum Mow-
Ball  Support may be more appropriate for your working conditions. Call
1(800)DR-OWNER(376-9637) for advice and assistance.
