SYMPTOM POSSIBLE CAUSE
The Engine will not
start using Electric-
Start.
(Please refer to the
Engine Owner’s
Manual for engine-
specific procedures.)
⇒ Check all the items under the section called Electric-Starting on page 23.
⇒ Check the previous section on Manual Starting for possible causes.
⇒ Check the In-Line Fuses in front of the Battery (Figure 4 on page 14).
⇒ Check the wire connections, especially the ground connection. This is the large
black wire leading from the Battery, and connected to the Engine.
⇒ Check the wire connections to the Solenoid. To avoid sparks, first disconnect the
black Battery ground wire. 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.
⇒ The Battery may not be charged. Check the voltage yourself or at a service 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 32.
⇒ If the Battery is charged and your DR ROTO-HOG POWER TILLER still will not
start, call 1-800-DR-OWNER (376-9637) for assistance.
The Engine lacks
power or is not
running smoothly.

⇒ Check the Throttle; it should be set in the FAST position.
⇒ The Air Filter may be dirty; change it following the procedure in the Engine

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.
⇒ The gas may be old; change it if necessary. Use a fuel stabilizer if you keep gas
longer than one month.

page 31.
