obstruction from the auger/impeller or the discharge chute.

2. Move the throttle to the Fast position.
3. Release the auger/impeller drive control lever and the
traction control lever (Fig. 14).

6. Insert the ignition key (Fig. 15).
Important Do not use the primer or the choke if the
engine has been running and is hot. Excessive priming may
flood the engine and prevent it from starting.
7. Cover the hole in the center of the primer (Fig. 15) with
your thumb and push in the primer 3 times, pausing a
moment between pushes.
8. For the recoil starter:
A. Grasp the recoil starter handle (Fig. 16) and pull it
out slowly until positive engagement results; then
pull the handle vigorously to start the engine.
B. Keep a firm grip on the starter handle and return the
rope slowly.
For the electric starter:
A. Connect the power cord to the snowthrower
(Fig. 17) and to a standard household power outlet.
Caution
If you leave the snowthrower plugged into a power
outlet, someone can inadvertently start the
snowthrower and injure people or damage
property.
Unplug the power cord whenever you do are not
starting the snowthrower.
B. Push the starter button.
Note: Run the electric starter no more than 10 times at
intervals of 5 seconds on, then 5 seconds off.
Important Running the electric starter extensively can
overheat and damage the starter.
Note: If the engine does not start after this series of
attempts, wait at least 40 minutes to allow the starter to
cool before attempting to start it again.
Note: If the engine does not start after the second series
of attempts, take the snowthrower to an Authorized
Service Dealer for service.
C. When the engine starts, disconnect the power cord
from the snowthrower and the outlet.
Note: If engine does not start or if the air temperature is
–10 F (–23 C) or below, the engine may need additional
priming. After pushing in the primer, try to start the engine
before priming again.
9. After the engine starts, immediately rotate the choke
(Fig. 15) to the 3/4 position. As the engine warms up,
rotate the choke to the 1/2 position. When the engine
warms up sufficiently, rotate the choke to the Off
position.
