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.
START THE ENGINE
Be sure that engine oil is at FULL mark on the oil fill cap/dipstick. The snow
thrower 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.
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 snow thrower is running, hot, or when snow thrower
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.

A
, Figure 10). Pull
the starter cord handle slowly until resistance is felt, then pull rapidly.
WARNING: Rapid retraction of the starter cord (kickback)
will pull your hand and arm toward the engine faster
than you can let go. Broken bones, fractures, bruises,
or sprains could result. When starting engine, pull the
starter cord slowly until resistance is felt and then pull
rapidly to avoid kickback.
NOTE: If the engine does not start after three attempts, see the
Engine Manual Troubleshooting section.
8. Electric Start: First connect the extension cord to the power cord
receptacle and then into a wall receptacle. If additional extension cord is
required, make sure it is three-wire.
WARNING: If the extension cord is damaged, it must
be replaced by the manufacturer (or its service agent)
or a similarly qualified person to avoid a hazard.
Starting with Electric Start Figure 11
IMPORTANT: To extend the life of the starter, use short
starting cycles (five seconds maximum). Wait one minute
between starting cycles.

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 snow throwers. 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 snow thrower thoroughly after each use.
8. Remove ice and snow accumulation and all debris from the entire
snow thrower, and flush with water (if possible) to remove all salt or
other chemicals. Wipe snow thrower dry.
9. Before starting snow thrower, always inspect augers and impeller for
ice accumulation and/or debris, which could result in snow thrower
damage.
10. Check oil level before every start. Make sure the oil is at the FULL
mark on the oil fill cap/dipstick.

LUBRICATE AUGER GEAR BOX
The auger gear box is lubricated at the factory and should not require
additional lubrication. If for some reason the lubricant should leak out,
or if the auger gear box has been serviced, add Lubriplate GR132 Grease or
equivalent. Maximum 3- 1/4 ounces, (92 grams) should be used.
Remove filler plug (A
A
, Figure 14), once a year. If grease is visible, do not
add. If grease is not visible, use a piece of fine wire, like a dipstick to check
if there is grease in the gear box. Mobilux EP1 and Shell Alvania EP1 are
suitable equivalents.
