NOTE: DO NOT use the choke to start a warm engine.
NOTE: DO NOT use the primer to start a warm engine.
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
reformulated automotive gasoline with a minimum of 85 octane along with
a fuel stabilizer (follow instructions on fuel stabilizer package). D
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 11/2 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.
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 engine 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 threehole 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

traumatic amputation or severe laceration can result.
A clean-out tool (AA, 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.
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
adjusted 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.
