ENGINE
LUBRICATION
Check the crankcase oil level before
starting the engine and after each five
(5) hours of continuous use. See
Figure 11. Add S.A.E. 5W30 motor oil
as needed. Tighten oil fill cap/dipstick
securely each time you check the oil
level.
011Fill Cap/Dipstick
NOTE: 0il level must be between the
FULL and ADD mark.
Figure 11
Change the oil every twenty-five (25)
hours or at least once a year if the
snow thrower is not used for twenty-five
(25) hours.
HOW TO CHANGE THE ENGINE OIL
To change the engine oil, the engine
must be tilted forward and the oil
drained from the oil fill tube as follows.
1. Lift the rear of the snowthrower and
tilt the unit forward. In the correct
position, the snowthrower will be
setting on the front of the auger
housing.
2. Put an oil drain pan under the oil
fill tube (See Figure 12).
3. Carefully remove the oil fill cap/dip-
stick. Oil will begin to flow into the
oil drain pan.
4. After all the oil has drained from the
engine, set the snowthrower in the
upright operating position.
5. 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 OVERFILL.
NOTE: For extreme cold operating
conditions of 0°F and below, use a par-
tial synthetic 5W30 motor oil for easier
starting.
SPARK PLUG
Check the spark plug every twenty-five
(25) hours. Replace the spark plug if
the electrodes are pitted or burned or if
the porcelain is cracked.
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 and reset gap to 0.30"
if necessary. See Figure 13.
3. Before installing the spark plug,
coat the threads lightly with oil for
easy removal. Tighten the spark
plug to a torque of 15 foot-pounds.
