Starting the Engine
DANGER
POTENTIAL HAZARD
When the snowthrower is running, the impeller
and auger can be rotating.
WHAT CAN HAPPEN
The rotating auger/impeller can cut off or
injure hands and feet.
HOW TO AVOID THE HAZARD
Before adjusting, cleaning, repairing and
inspecting the snowthrower, and before
unclogging the discharge chute, shut the engine
off and wait for all moving parts to stop. Also,
pull the wire off of the spark plug and keep it
away from the plug to prevent someone from
accidentally starting the engine.
Use a stick, not your hands, to remove an
obstruction from the discharge chute.
Stay behind the handles and away from the
discharge opening while operating the
snowthrower.
Keep face, hands, feet, and any other part of
your body or clothing away from concealed,
moving or rotating parts.
IMPORTANT:
Check the auger, impeller, and the
discharge chute contain no obstructions before you
operate the snowthrower. Use a stick, not your hand, to
remove an obstruction from the discharge chute.
1. Move the throttle (Fig. 16) to the Fast position.
2. Open the fuel shut–off valve below the fuel tank
(Fig. 17) by rotating it to the left.
3. Rotate the choke (Fig. 16) to full choke position.
4. Cover the hole in center of the primer with your thumb
and push the primer slowly three times, pausing for
two seconds between each push. Do not use the
primer if the engine has been running and is hot.
Note:
Excessive priming may flood the engine and
prevent it from starting.
5. Insert the ignition key (Fig. 16).
6. Grasp the recoil starter handle (Fig. 18) and pull it out
slowly until positive engagement results; then pull it
vigorously to start the engine.
7. Keep a firm grip on starter handle and return the rope
slowly.
Note:
If engine does not start or if temperature is –10 F
(–23 C) or below, the engine may need additional
priming. After each push of the primer, try to start the
engine before priming again.
8. After the engine starts, immediately rotate the choke
(Fig. 16) to the 3/4 position.
9. As the engine warms up, rotate the choke to the 1/2
position; then to the Off position.
If the engine falters, return the choke to the 1/2
position until the engine warms sufficiently, then rotate
the choke to the Off position.
Before Stopping the Engine
1. Release the traction and auger/impeller drive controls
(Fig. 15).
2. Engage the auger/impeller to clear any remaining
snow from inside the housing.
3. Run the engine for a few minutes to help dry off any
accumulated moisture.
4. With the engine running, pull the recoil starter with a
rapid, continuous, full arm stroke three or four times.
This helps prevent possible freeze–up of the recoil
starter.
Note:
Pulling the starter rope produces a clattering sound.
This is not harmful to the engine or the starter.
Stopping the Engine
1. Release the traction and auger/impeller control levers
(Fig. 15).
2. Move the throttle to slow and remove the ignition key
(Fig. 16).
3. Wait for all moving parts to stop before leaving the
operator's position (behind the handles).
Freewheeling or Self-propelled
Drive
You can operate the snowthrower with the self–propelling
feature engaged or disengaged (freewheeling). There are
two holes in each end of the axle. When you insert the
axle pins through the outer axle holes and not through the
wheel hubs (Fig. 4), the snowthrower freewheels. When
