WARNING

TO PREVENT ELECTRIC SHOCK:

•Do not use the 120VAC electric starter in the rain.

•Do not stand in water or on damp sur- faces when using the electric starter or when connecting power cord.

•Connect the power cord only to a prop- erly grounded, 120VAC wall outlet.

•Review electric start safety messages in the Engine Owner’s Manual and in Section 1 of this Manual.

a.Plug power cord supplied with unit into the electric start switch box (R, Figure 4-2) on the engine.

b.Plug the other end of the power cord into a properly grounded, 3- pronged 120VAC wall outlet.

IMPORTANT: To prolong starter life, use short starting cycles (five seconds maxi- mum, then wait one minute).

c. Push the starter button (P, Figure 4-2) on the switch box. When the engine starts, release the button.

Disconnect power cord from wall outlet and then from engine. (Store power cord in a secure place, safely out of the reach of children.) If en- gine fails to start, repeat starting in- structions beginning with Step 3.

NOTE: The starter is thermally pro- tected. If overheated from continu- ous use, it will stop automatically and can be restarted only when it has cooled to a safe temperature (a wait of approximately 5-10 minutes is required).

d. Let engine warm up. Rotate Choke Knob (M, Figure 4-2) toward RUN setting a little at a time over several seconds in warm weather, or min- utes in cold weather. Let engine run smoothly before each change. Operate engine with choke in RUN.

e. Allow unit to adjust to outside tem- perature before clearing snow.
