(Please refer to the

Manual for Engine-
specific procedures.)
⇒ Check all the items under the section called Electric-Starting on page 19.
⇒ Check the previous section (Manual Starting) for possible causes.
⇒ 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 is bolted to the Frame.
Using a wrench or socket, tighten the bolts to ensure a good connection to the
Frame.
⇒ The Battery may not be 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
vacuum for at least 45 minutes at a time, the Battery may need to be periodically
charged. See the Battery Care section on page 32.
⇒ If your Battery is charged and your DR WALK-BEHIND LEAF & LAWN VACUUM
still will not start, call 1-800-DR-OWNER (376-9637) for assistance.

the Cylinder, then wipe off the Plug and reinsert it.

one month.
