The Engine won’t start
using Electric-Start.
(Please refer to the
Engine Owner’s manual
for Engine-specific
procedures.)
 Check all of the items under the section called Electric Starting on page 12 and the previous
section on Manual Starting.
 Check the wire connections - especially the ground connection, the large black wire coming
from the Battery, where it connects to the Engine.
 Make sure the Battery is charged. Check the voltage yourself or at a service station. If it is
low, charge it with a 12-volt, 1 to 2 Amp trickle charger. If you do not use your machine for
at least 45 minutes at a time, the Battery may need to be periodically charged. See the
Battery Care section on page 25.
 If your Battery is charged and your DR TRIMMER/MOWER still won’t start, visit our web
site at www.DRPower.com or call 1-800-DR-OWNER (376-9637) for assistance.
The Engine lacks power
or is not running
smoothly.
(Please refer to the
Engine Owner’s Manual
for Engine-specific
procedures.)
 Check the Throttle travel. The Throttle Lever should be in the most forward position (RUN
position) when the engine is warm.
 Check for debris (hay seed, etc.) clogging the Air Filter Intake and clean out as required.
 The Engine’s Blower Housing, Throttle Linkage, and Cooling Fins should be free of debris.
Clean them following the instructions in the Engine Owner’s Manual.
 Check that the Air Filter is clean. If it is dirty, change it following the procedure in the
Engine Owner’s Manual.
 Remove the Spark Plug wire and dry the connection with a rag.
 The Spark Plug may be dirty or cracked, change it. If it’s oily, leave it out, hold a rag over
the Spark Plug hole and pull the Recoil Cord several times to blow out any oil in the
Cylinder, then wipe off the Spark Plug and reinsert it.
 You should be using fresh, clean, unleaded gas. If it is old, change it. Use a fuel stabilizer
if you keep gas longer than one month.
 Check that the Engine has the right amount of clean oil. If it is dirty, change it following the
procedure on page 23.
 If your Engine still lacks power, visit our web site at www.DRPower.com or call 1-800-DR-
OWNER (376-9637) for assistance.
The Trimmer Head
won’t spin or lacks
power.  Check for proper alignment of the V-Belt. Check it against Figure 27 in the “Replacing the
Belt” section on page 19.
 The Belt may be worn or frayed; if so, replace it.
 If the Trimmer Head still will not spin, follow the procedure for “Adjusting the Trimmer
Head Belt Tension through the Trimmer Control Cable” on page 24.
 If none of the above helps, visit our web site at www.DRPower.com or call 1-800-DR-
OWNER (376-9637) for assistance.
The Trimmer Head
keeps spinning or spins
when you release the
Engage Bar.  Check for proper alignment of the V-Belt. Check it against Figure 27 in the “Replacing the
Belt” section on page 19.
 If you just installed a new belt, make sure you run it in by engaging the head at least 10
times.
 If the Trimmer Head keeps spinning when you release the Engage Bar, see “Adjusting the
Trimmer Head Belt Tension through the Trimmer Control Cable” on page 24.
 If none of the above helps, visit our web site at www.DRPower.com or call 1-800-DR-
OWNER (376-9637) for assistance.
