The Engine lacks power
or is not running
smoothly.
(Please refer to the
Engine Owner’s Manual
for Engine-specific
procedures.)
 Check the Throttle Lever. The Throttle Lever should be in the fast (rabbit) position.
 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 20.
 If your Engine still lacks power, visit our web site at www.DRPower.com or call 1-800-DR-

The Mow-Ball ® is
wearing too quickly.

leveled to the height adjustment. Adjust the Tow Hitch so the Mow-Ball ® is not touching
the ground while trimming.

obstacles. Try approaching them slowly, and from different directions, to avoid
unnecessary wear.
