8. To start engine with recoil starter:
a. Before pulling recoil starter (N,
Figure 4-2), be sure there are no
obstacles behind you.
b. Pull recoil starter handle rapidly to
overcome engine compression, pre-
vent kick-back and start engine.
Maintain control of rope so it slowly
returns into the starter mechanism.
Repeat pulling until engine starts. If
engine fails to start, repeat starting
instructions beginning with Step 3.
c. 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.

perature before clearing snow.
8. To start engine with electric starter:
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.
