Assembly & Operating Instructions
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 tips in the section on breaking
cords above. Also, try the different methods of
attaching the cord shown in the Cutting Cords
section of this manual.
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, usable on the Standard,
Quantum and "Pro" model trimmers only.
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.
Mow-Ball
ä Support is wearing too quickly Þ Are you pushing the trimmer head down into the
ground? The DR
®
TRIMMER/MOWER
ä works
best with a light touch, with the Mow-Ball
ä
Support resting easily on the ground.
Þ Are you hitting the Mow-Ballä Support against
rocks, concrete driveways or other hard
obstacles? Try approaching them slowly, and
from different directions, to avoid unnecessary
wear.
