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 18 and the
previous section on Manual Starting.
⇒ Check the wiring behind the Key switch; it may have vibrated off the Switch
terminals.
⇒ Check the wire connections - especially the ground connection, the large black wire
coming from the Battery, where it connects to the Engine.
⇒ Check the wire connections to the Solenoid. Disconnect the black Battery ground
wire first to avoid sparks. Check to be sure that all of the connections are clean and
tight. Reconnect the Battery ground wire.
⇒ Check the ground connection on the Solenoid where it bolts to the Frame. Using a
wrench or socket, tighten the Bolts to ensure a good connection to the Frame.
⇒ Make sure the Battery is charged. Check the voltage yourself or at a gas 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 30.
⇒ If your Battery is charged and your DR TRIMMER/MOWER still won’t start, 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 Run position.
⇒ Check for debris (hay seed, etc.) clogging the Air Filter Intake and clean out as
required.
⇒ The blower housing, throttle linkage, and cooling fins should be free of debris.
Clean them following the instructions in the Engine Owner’s Manual.
⇒ The Air Filter should be clean. If it’s dirty, change it following the procedure in the
Engine Owner’s Manual.
⇒ Remove the Spark Plug wire and dry the connection with a rag.
⇒ Check that the Spark Plug is clean. If it’s fouled 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 40.
⇒ If your Engine still lacks power, call 1-800-DR-OWNER (376-9637) for assistance.
