FILL THE FUEL TANK
This engine is certified to operate on gasoline. Exhaust Emission Control
System: EM (Engine Modifications).
Fill the fuel tank with fresh, clean, unleaded regular, unleaded premium, or re-
formulated automotive gasoline with a minimum of 85 octane along with a
fuel stabilizer (follow instructions on fuel stabilizer package). D
DO NOT
use
leaded gasoline. We recommend that fuel stabilizer be added to the fuel
each time that gasoline is added to the fuel tank.
NOTE: Winter grade gasoline has higher volatility to improve
starting. Be certain container is clean and free from rust or
other foreign particles. Never use gasoline that may be stale
from long periods of storage in the container.
CAUTION: DO NOT use gasoline containing any
amount of alcohol as it can cause serious damage to
the engine or significantly reduce the performance.
WARNING: Gasoline is flammable. Always use
caution when handling or storing gasoline. Turn
engine off and let engine cool at least two minutes before
removing the gas cap. Do not add gasoline to the fuel tank
while snowthrower is running, hot, or when snowthrower is
in an enclosed area. Keep away from open flame,
electrical sparks and DO NOT SMOKE while filling the fuel
tank. Never fill the fuel tank completely; but fill the fuel
tank to within 1-1/2 inches (3.8 mm) from the top to
provide space for the expansion of the fuel. Always fill fuel
tank outdoors and use a funnel or spout to prevent spilling.
Make sure to wipe up any spilled fuel before starting the
engine.
Store gasoline in a clean, approved container, and keep
the cap in place on the container. Keep gasoline in a cool
well ventilated place; never in the house. Never buy more
than a 30 day supply of gasoline to assure volatility.
Gasoline is intended to be used as a fuel for internal
combustion engines; therefore, do not use gasoline for any
other purpose. Since many children like the smell of
gasoline, keep it out of their reach because the fumes are
dangerous to inhale, as well as being explosive.

cap/dipstick. Do not add too much oil.
6. Tighten the oil fill cap/dipstick securely each time you check the oil
level.
NOTE: Synthetic 5W30 motor oil is acceptable for all tempera-
tures. DO NOT mix oil with gasoline. See Chart for oil recom-
mendations.

START THE ENGINE
Be sure that engine oil is at FULL mark on the oil fill cap/dipstick. The snowthrower
engine is equipped with an A.C. electric starter and recoil starter. Before starting the
engine, be certain that you have read the following information.
If engine floods, set the choke to the OPEN/RUN position and crank until the en-
gine starts.
WARNING: The electric starter is equipped with a
three−wire power cord and plug designed to operate on AC
house hold current. The power cord must be properly
grounded at all times to avoid the possibility of electric shock
which can cause injury to the operator. Follow all instructions
carefully as set forth:
Make sure your house has a three−wire grounded system.
If you are not sure, ask a licensed electrician. If your house does
not have a three−wire grounded system, do not use this electric
starter under any condition.
If your house has a three−wire grounded system but a three-hole
receptacle is not available to connect the electric starter, have a
three−hole receptacle installed by a licensed electrician.
WARNING: To connect power cord, always connect the
power cord first to the switch box located on the
engine and then plug the other end into a three−hole
grounded receptacle.
WARNING: To disconnect the power cord, always
unplug the end connected to the three−hole grounded
receptacle first.

CLEAR A CLOGGED DISCHARGE CHUTE
DANGER: Hand contact with the rotating impeller inside
the discharge chute is the most common cause of injury
associated with snowthrowers. Never clear or unclog
discharge chute with your hands, or while engine is
running. Fingers can quickly become caught and
traumatic amputation or severe laceration can result.
OPERATING TIPS
1. Most efficient snowthrowing is accomplished when snow is removed
immediately after it falls.
2. For complete snow removal, slightly overlap each swath previously taken.
3. Snow should be discharged downwind whenever possible.
4. For normal usage, set the skids 1/8 inch (3 mm) below the scraper
bar. For extremely hard-packed snow surfaces, the skids may be ad-
justed upward to ensure cleaning efficiency.
5. On gravel or crushed rock surfaces, the skids should be set at 1-1/4
inch (32 mm) below the scraper bar (see “Adjust Skid Height” in the
MAINTENANCE section of this manual). Rocks and gravel must not
be picked up and thrown by the machine.
6. After the snowthrowing job has been completed, allow the engine to
idle for a few minutes, to melt snow and ice accumulated on the
engine.
7. Clean the snowthrower thoroughly after each use.
8. Remove ice and snow accumulation and all debris from the entire
snowthrower, and flush with water (if possible) to remove all salt or
other chemicals. Wipe snowthrower dry.
9. Before starting snowthrower, always inspect augers and impeller for
ice accumulation and/or debris, which could result in snowthrower
damage.
10. Check oil level before every start. Make sure the oil is at the FULL
mark on the oil fill cap/dipstick.
Clean-Out Tool Figure 19
A
SHUT OFF THE ENGINE!
Wait 10 seconds to be sure that the impeller blades have stopped
rotating.
Always use a clean-out tool, not your hands.
A clean-out tool (A
A
, Figure 19) is attached to either the handle or the top of the
auger housing. Use the clean-out tool to remove snow from the auger housing.
