SYMPTOM POSSIBLE CAUSE
The Engine will not stop.
 Release the blade control Bar. If the engine does not stop when the blade control Bar is
released, pull the spark plug wire off the spark plug using insulated handle pliers and call us
at 1-800-DR-OWNER (376-9637) for assistance.
 Make sure that the Wire harness did not disconnect from the key switch. Reconnect if it
has.
Engine smokes.
 Check the oil level and adjust as needed.
 You may be operating the machine on too great an incline.
 Check the Air Filter and clean or replace as needed.
 You may be using the wrong oil - too light for the temperature. Refer to your Engine
Owner’s Manual for detailed information.
 Clean the Engine cooling fins and the carburetor housing if they are dirty.
 If the Engine still smokes, visit our web site at www.DRPower.com or call 1-800-DR-OWNER
(376-9637) for assistance.

or is not running
smoothly.
(Please refer to the
Engine Owner’s Manual
for Engine-specific
procedures.)
 Check the height of cut settings. Raise the height of cut if the grass is high.
 Allow the engine to fully warm up if it is cold. The Auto Choke feature requires a cold engine
to heat to operating temperature prior to achieving full operating RPM.
 Check the bottom of the mower housing. Clean the blade housing of grass and other debris.
 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 oil.
 If your Engine still lacks power, visit our web site at www.DRPower.com or call 1-800-DR-
OWNER (376-9637) for assistance.
Excessive Vibration
 Remove the blades and check for balance. Repair or replace as needed.
 Check for a bent or broken blade. A DAMAGED BLADE IS DANGEROUS AND MUST BE
REPLACED.
 Check the blade adapter. Replace a broken blade adapter.
 If the vibration continues, visit our web site at www.DRPower.com or call 1-800-DR-OWNER
(376-9637) for assistance.

every two years with a DR Power replacement blade.
