sembly or maintenance to the snow
thrower, remove the wire from the
spark plug.
NOTE: In this instruction book, left and right
describe the location of a part from the oper-
ator’s position behind the unit.
NOTE: Torque is measured in foot pounds
(metric N.m). This measurement describes
how tight a nut or bolt must be. The torque is
measured with a torque wrench.

How To Remove The Snow Thrower
From The Carton
1. Locate and remove the container of oil.
2. Locate all parts that are packed separately
and remove from the carton.
3. Remove and discard the packing material
from around the snow thrower.
4. Cut down all four corners of the carton and
lay the side panels flat.
5. Hold onto the lower handle and pull the snow
thrower off the carton.
CAUTION: DO NOT back over cables.
6. Remove the packing material from handle
assembly. Remove the lower insert from the
axle.
How To Assemble The Handle
1. Remove the packing material from the upper
and lower handles.
2. (Figure 2) Loosen the knobs (1) on each
side of the handle (2).
3. Raise the upper handle (2) to the operating
position. Hold the upper handle (2) apart to
prevent scratching the lower handle.

not caught between the upper and lower
handle.
4. Tighten the knobs (1).
How To Prepare The Engine
WARNING: Follow the engine
manufacturer’s instructions for the
type of fuel and oil to use. Always
use a safety fuel container. Do not smoke
when adding fuel to the fuel tank. When
inside an enclosure, do not fill the fuel
tank. Before you add the fuel, stop the en-
gine. Let the engine cool for several min-
utes.
See the engine manufacturer’s instructions for
the type of fuel and oil to use. Before you use
the unit, read the information on safety, opera-
tion, maintenance, and storage.
NOTE: Engine horsepower ratings may vary
by engine adjustments, manufacturing vari-
ances, altitude, atmospheric conditions, fuel
and maintenance.
Add Oil To The Engine (Figure 3)
NOTE: Engine may already contain some
residual oil. Check frequently when filling
the crankcase. DO NOT overfill.
The snow thrower was shipped with a container
of 5W30 motor oil. This oil must be added to the
engine before operating.
1. Make sure the unit is level.
2. Remove the
oil fill cap/dipstick (1) and fill
the crankcase to “ FULL ” line on dipstick. DO
NOT overfill.
3. Tighten the oil fill cap/dipstick (1) securely
each time you check the oil level.
NOTE: Synthetic oil can assist with starting
in extreme cold temperatures. Synthetic
5W30 is acceptable for all temperatures. DO
NOT mix oil with petrol.
Add Petrol To The Engine
This engine is certified to operate on petrol. Ex-
haust Emission Control System: EM (Engine
Modifications).
WARNING: Alcohol blended fuels
(called gasohol or those using
ethanol or methanol) can attract
moisture which leads to separation and
formation of acids during storage. Acidic
gas can damage the fuel system of an en-
gine while in storage.
NOTE: To avoid engine problems, the fuel
system must be emptied before storage for
30 days or longer. Start the engine and let it
run until the fuel lines and carburetor are
empty. Use fresh fuel next season. See the
Storage section in this manual for additional
information.
Fill the fuel tank only with a fresh, clean, un-
leaded regular, unleaded premium, or reformu-
lated automotive petrol with a minimum of 85
octane. DO NOT use leaded petrol. Make sure
that the container you pour the petrol from is
clean and free from rust or other foreign par-
ticles. Never use petrol that may be stale from
long periods of storage in the container.
