(Recoil Start) Slowly pullthe recoil
starter handle untilresistance is
feltandthen pull rapidlyto start the
engine. Do not allow the recoil
starter handle to snap back. Slowly
return the recoil starter handle.
9. If the engine does not start Jn5 or 6
tries, See DifficultStarting in the
=Troubleshooting Table'.
10.Allow the engine to warm up for
several minutes. As the engine
warms up, adjust the choke knob
toward the RUN position.Wait until
the engine runs smoothlybefore
each choke adjustment.
11. (Electric Start) First disconnect
power cord from receptacle. Then,
disconnectthe power cordfrom the
starter motor.
How To Start A Warm Engine
If restaK_nga warm engine after a short
shutdown, leave the choke Feverin the
off positionand do not push the primer
button, if the engine fails to start, follow
the Cold Start instructions.
Frozen Starter
Ifthe starter is frozen and will not turn
the engine, follow the steps below.
1. Pullas much starter rope as pos-
sible out of the starter.
2. Release the starter handle and let it
snap back against the starter. Re-
peat untilthe engine starts.
Warm engines will cause condensation
in coldweather. To prevent possible
fTeeze-up of recoil starter and engine
controls, proceed as follows after each
snow removaljob.
1. With engine off, alisw engine to cool
for several minutes.
2. Pullstarter rope very slowly until re-
sistance is felt, then stop. Allow the
starter rope to reooi_.Repeat three
times.
3. W'_ the engine not running, wipe all
snow and moisture from the carbu-
retor cover in area of controls and
levers. Also, move the choke control
and starter handle several times.

SNOW THROWING TIPS
1. For maximum snow thrower efficien-
cy inremoving snow,adjust ground
speed. Go slower in deep, freezing
or wet snow. If the wheels slips, re-
duce forward speed.
2. Mostefficient snow throwing is ac-
complished when the snow is re-
moved immediately after iffalls.
3. For complete snow removal, sligh'dy
overlap each path previously taken.
4. The snow should be discharged
down wind whenever possible.
5. For normal usage, set the skids so
that the scraper bar is 1/8" above
the skids. For extremely hard-
packed snow surfaces, adjust the
skids upward so that the scraper
bar touches the ground.
6, On gravel or crushed rock surfaces,
Release auger drive lever.
Remove (do not turn) safety key.
Disconnect spark plug wire.
Do not place your hands in the au-
ger ordischarge chute. Use the
cleaning stick to remove snow.
set the skids at 1-1/4" below the
scraper bar. See To Adjust Skid
Height paragraph in the Service &
Adjustments section of this manu-
al. Rocks and gravel must not be
picked up and thrown bythe ma-
chine.
.
After the snow throwing job has
been completed, allow the engine to
idlefor a few minutes, which will
melt snow and accumulated ice off
the engine.
,
Clean the snowthrower thoroughly
after each use.
9.
Remove ice and snow accumulation
and all debris from the entire snow
thrower, and flush with water (if pos-
sible) to remove all salt or other
chemicals. Wipe snow thrower dry.

POWER RATINGS
The power ratings for an individual
engine model are initiallydeveloped by
starting with SAE (Society ofAutomo-
tive Engineers) code J1940 (Small
Engine Power & Torque Rating Proce-
dure) (Revision 2002-05). Given both
the wide array ofproducts onwhich our
engines are placed, and the variety of
environmental issues applicable to
operating the equipment, itmay be that
the engine you have purchased will not
develop the rated horsepower when
used in a piece of power equipment
(actual "on-site" power). This difference
is due to a variety of factors including,
but not limitedto, the following: differ-
ences in altitude,temperature, baro-
metric pressure, humidity,fuel, engine
lubrication, maximum governed engine
speed, individualengine to engine
variability, design ofthe particular piece
of power equipment, the manner in
which the engine is operated, engine
run-in to reduce frictionand clean out of
combustion chambers, adjustmentsto
the valves and carburetor,and other
factors. The power ratingsmay also be
adjusted based on comparisons to
other similar engines utilized in similar
applications, and willtherefore not
necessarily match the values derived
using the foregoing codes.

3, Remove the bottom panel.
4. Lubricate the chains with a chain
type lubricant.
5. For storage, wipe the hexshaft and
sprockets with 5W30 motor oil.

1. Make sure the spark plug is clean.
Clean the spark plug by carefully
scraping the electrodes (do not
sand blast or use a wire brush).
2. Check the spark plug gap with a
feeler gauge end reset gap to 0.30"
