Operation
Starting the Engine
NOTE: For complete
and detailed
engine starting,
stopping
and
storing
instructions,
it is recommended
that you read the engine
manual also included
with this machine.
NOTE:To avoid carbon monoxide
poisoning,
make sure the
engine is outdoors
in a well-ventilated
area.
1.
Attach spark plug wire to spark plug. Make certain the
metal loop on the end of the spark plug wire (inside the
rubber
boot) is fastened
securely over the metal tip on the
spark plug.
2.
Make certain
both the auger control
and drive control are
in the disengaged
(released)
position.
3.
Move throttle
control
up to FAST position.
Insert ignition
key into slot. Make sure it snaps into place. Do not attempt
to turn the key.
NOTE:The
engine cannot
start unless the key is inserted
into the ignition
switch.
4.
Rotate choke control
to FULL choke position
(cold engine
start).
NOTE: If the engine
is already warm, place choke control
in
the OFF position
instead
of FULL.
5.
Push the primer two or three times for cold engine start,
making
sure to cover vent hole in the center of the primer
when pushing.
NOTE: DO NOT use primer to restart a warm engine after a
short shutdown.
NOTE:Additional
priming
may be necessary if the
temperature
is below
15° Fahrenheit.
6.
Grasp the recoil starter handle and slowly pull the rope out.
At the point where it becomes
slightly
harder to pull the
rope, slowly allow the rope to recoil.
7.
Pull the starter handle with a firm, rapid stroke. Do not
release the handle and allow it to snap back. Keep a firm
hold on the starter handle and allow it to slowly recoil.
8.
As the engine warms, slowly rotate the choke control to the
OFF position.
If the engine falters, quickly
rotate the choke
control
back to the FULL position
and then slowly into the
OFF position
again.
NOTE: Allow the engine to warm up for a few minutes
after
starting.
The engine will not develop
full power until it
reaches operating
temperatures.
9.
Operate
the engine at full throttle
(FAST) when throwing
snow.
Stopping the Engine
Run engine for a few minutes to help dry off any moisture on
engine.
1.
To stop the engine, move the throttle control lever to the
OFF position or pull out the key (either method works). Do
not attempt to turn key as this could cause it to break.
2.
Remove the ignition key and store in a safe place.
3.
Wipe all snow and moisture from the area around the
engine as well as the area in and around the drive control
and auger control. Also, engage and release both controls
several times.

1.
2.
Move the throttle
control
into the Fast (rabbit) position.
To engage the drive, squeeze the drive control
completely
against the upper handle to engage the wheels. To stop
the forward
motion,
release the drive control.
Engaging the Augers
To engage the augers, squeeze the auger control
handle
completely
against
the upper handle. To stop the augers,
release handle.
Replacing Shear Pins
The augers are secured to the spiral shaft with two shear pins
and cotter
pins. If the auger should
strike a foreign
object or ice
jam, the snow thrower
is designed
so that the pins may shear. If
the augers will not turn, check to see if the pins have sheared.
