 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 clean oil. If it is dirty, change it following the
procedure in Chapter4.
 If your Engine still lacks power, visit our web site at www.DRPower.com or call 1-800-DR-
