The Engine won’t
start using electric-
start.
(Please refer to the
Engine Owner’s
Manual for engine-
specific procedures.)
⇒ Check the previous section (Manual Starting) for possible causes.
⇒ There is a fuse in the wiring harness. Check the fuse and replace if needed.
⇒ 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’s bolted to the frame.
Using a wrench or socket, tighten the bolts to ensure a good connection to the
frame.
⇒ The Battery should be charged. Check the voltage yourself or at a gas station. If
it’s low, charge it with a 12-volt, 1 to 2 Amp trickle charger. If you do not use your
vacuum for at least 45 minutes at a time, the Battery may need to be periodically
charged. See the Battery Care section on page 38.
⇒ If your Battery is charged and your DR still won’t start, visit our website 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. See page 26.
⇒ The Choke should be pushed all the way to the left (RUN). See page 26.
⇒ Check to see if the Air Filter is clean. If it’s dirty, change it following the procedure
in the Engine Owner’s Manual.
⇒ The Spark Plug should be clean. If the Spark Plug is dirty or cracked, change it. If
it’s oily, leave it out, hold a rag over the Plug hole and pull the Recoil Cord several
times to blow out any oil in the cylinder, then wipe off the Plug and reinsert it.
⇒ You should be using fresh, clean gas. If the gas is old, change it. Use a fuel
stabilizer if you keep gas longer than one month.
⇒ Check and make sure the Engine has the right amount of clean oil. If it’s dirty,
change it following the procedure on page 37.

Engine smokes. ⇒ Check the oil level and adjust as needed.
⇒ You may be operating the machine on too great an incline. See Slopes on page

⇒ Check the Air Filter and clean or replace if 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 website at
