ENGLISH
WARNING: The starter is equipped
with a three-wire power cord and
plug and is designed to operate on
120 volt A.C. household current. The power
cord must be properly grounded at all times
to avoid the possibility of electrical shock
which can injure the operator. Carefully fol-
low all instructions in the "How To Start The
Engine" section. Make sure that your house
wiring is a three-wire grounded system. If
you are not sure, ask a licensed electrician.
If your house wire system is not a
three-wire grounded system, do not use
this electric starter under any conditions. If
your system is grounded but a three-hole
grounded receptacle is not available to start
the engine, have a three-hole grounded re-
ceptacle installed by a licensed electrician.
To connect a 120 volt A.C. power cord, al-
ways connect the power cord to the switch
box (11) on the engine first. Then, plug the
other end into the three-hole grounded re-
ceptacle. When disconnecting the power
cord, always unplug the end from the
three-hole grounded receptacle first.
How To Start A Cold Engine (Figure 2)
1. Fill the fuel tank with a fresh, clean fuel mis-
ture. See "How To Mix The Fuel Mixture" in
the Assembly section.
2. Move the choke control to FULL position.

disengaged (released) position.
4. Insert the ignition key (8) and turn to the on
position.
5. Move the choke control (14) to the full
choke position.
6. (Electric Start) Connect the power cord to

7. (Electric Start) Plug the other end of the
power cord into a three-hole, grounded 120
VOLT, A.C. receptacle. (See the WARNING
in this section).

when it has cooled to a safe temperature. A
wait of about 5 to 10 minutes is required to
allow the electric starter to cool.
