How To Check The Engine Oil
(Figure 3)
Check the oil level before starting the engine
and after each eight (8) hours of continuous use.
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.
How To Change The Engine Oil
Change the engine oil every fifty (50) hours or at
least once a year if the snow thrower is not used
for fifty (50) hours.
To change the engine oil, the engine must be
tilted forward and the oil drained from the oil fill
tube. Change oil when the engine is warm.
1.
(Figure 5)
Lift the rear of the snowthrower
and tilt the unit forward. In the correct posi-
tion, the snowthrower will be setting on the
front of the auger housing.
2. Put an
oil drain pan (1)
under the
oil fill
tube (2).
3. Carefully remove the oil fill cap/dipstick. Oil
will begin to flow into the
oil drain pan (2).
4. After all the oil has drained from the engine,
set the snowthrower in the upright operating
position.
5.
(Figure 3)
Fill the engine with S.A.E. 5W30
oil. Make sure the oil reaches the FULL mark
on the oil fill cap/dipstick. DO NOT OVER-
FILL.
NOTE: Synthetic oil can assist with starting
in extreme cold temperatures. Synthetic
5W30 is acceptable for all temperatures. DO
NOT mix oil with petrol.
How To Replace The Spark Plug
(Figure 20)
NOTE: This spark ignition system meets all
requirements of the Canadian Interference
−
Causing Equipment Regulations.
NOTE: This engine complies with all current
Australian and New Zealand limitations elec-
tromagnetic interference.
Check the
spark plug (1)
every twenty-five (
25
)
hours. Replace the
spark plug (1)
if the elec-
trodes are pitted or burned, if the porcelain is
cracked, or every
100
hours of use.
1. Make sure the
spark plug (1)
is clean. Clean
the
spark plug (1)
by carefully scraping the
electrodes (
do not sand blast or use a wire
brush
).
2. Check the
spark plug (1)
gap with a
feeler
gauge (2)
and reset gap to 0.030” if neces-
sary..
3. Before installing the
spark plug (1)
, coat the
threads lightly with oil for easy removal.
Tighten the

How To Prepare The Snow Thrower For
Storage
WARNING: Do not remove petrol
while inside a building, near a fire,
or while you smoke. Petrol fumes
can cause an explosion or a fire.
If the snow thrower is to be stored for an ex-
tended period, refer to the engine manufactur-
er’s operating manual (included with some
models) for important maintenance or storage
details.
1. Drain the fuel tank.
2. Let the engine run until it is out of gasoline.
3. Never store the snow thrower with fuel in the
tank inside a building where ignition sources
are present such as hot water and space
heaters, clothes dryers, and the like. Allow
the engine (motor) to cool before storing in
any enclosure.
4. Drain the oil from the warm engine. Fill the
engine crankcase with new oil.
5. Remove the spark plug from the cylinder.
Pour one ounce of oil into the cylinder. Slow-
ly pull the recoil
−
start grip so that the oil will
protect the cylinder. Install a new spark plug
in the cylinder.
6. Thoroughly clean the snow thrower.
7. Lubricate all lubrication points. See the Main-
tenance section.
8. Be sure that all nuts, bolts and screws are
securely fastened. Inspect all visible moving
parts for damage, breakage and wear. Re-
place if necessary.
9. Cover the bare metal parts of the blower
housing and auger with spray rust preventa-
tive lubricant.
10.Put the unit in a building that has good ven-
tilation.
11. If the machine must be stored outdoors,
block up the snow thrower to be sure the en-
tire machine is off the ground.
12.Cover the snow thrower with a suitable pro-
tective cover that does not retain moisture.
Do not use plastic.
