OPERATION
NOTE
When first operating snow thrower give
yourself ample time to acquaint yourself
with the machine. Practice using ALL
controls.
STARTING THE ENGINE (RECOIL
START)
1. Turn ignition switch to "ON"
position.
2. Pull choke.
3. Push primer button 1 to 4 times
(depending on temperature). In tempera­
tures above -t-15°F (-10°C) use one or
two primes. In temperatures below
-f15°F (-10°C) use three or four primes.
To prime engine, fully depress primer
bulb with your thumb (if primer bulb has
a vent hole, be sure thumb covers hole
when priming). Release and allow bulb to
return to original position. An engine
should be primed if it is new, cold, stored,
unused for an extended period of time or
has been run dry of fuel.
4. Start engine. Hot or cold start —
pull starter rope (see "STARTING
INSTRUCTIONS" in engine manual).
5. When engine starts, push choke con­
trol in (if choking was necessary).
6. Pull up auger clutch control (if so
equipped) to engage impeller. If adjust­
ment is necessary refer to CARE AND
MAINTENANCE section.
STARTING THE ENGINE (ELECTRIC
START)
1. Plug cord into starter switch con­
nector (H), Figure 6, and a convenient
120 volt outlet.
2. Follow steps 1,2 and 3 from recoil
start engine starting instructions.
3. Press starter button (see "START­
ING INSTRUCTIONS" - Electric Start
section in engine manual). Release as
soon as engine starts.
A
CAUTION
DO NOT CRANK WITH ELECTRIC
STARTER FOR MORE THAN 60
SECONDS. IF CRANKED FOR 60
SECONDS STARTER SHOULD NOT BE
OPERATED AGAIN FOR 20 MINUTES
TO ALLOW IT TO COOL.
4. After engine starts, push choke con­
trol in (if choking was necessary) and re­
move extension cord (from receptacle
first).
5. Pull up auger clutch control (if so
equipped) to engage impeller. If adjust­
ment is necessary refer to CARE AND
MAINTENANCE section.
STOPPING THE ENGINE
1. Turn ignition key to "OFF" position.
Remove key.
2. Be sure all moving parts have stopped
before leaving the operator's position.
A
CAUTION
STOP THE ENGINE BEFORE:
• Adding fuel.
• Leaving snow thrower unattended,
if only for a minute.
• Clearing discharge opening.
• Making any repairs or adjustments to
unit.
OPERATING TIPS
1. Before the first snowfall thoroughly
inspect area where snow removal will
take place. Remove all door mats, sleds,
boards, wires, etc. that might be picked
up and thrown by tbe impeller paddles.
2. Spray the inside of impeller paddle
housing and directional vanes with Bolens
silicone spray to help prevent snow build
up. A coat of paste wax is also suitable.
3. All covers and guards must be in
place and all nuts, screws and other
fasteners tight.
4. Allow engine to warm up approx­
imately five (5) minutes before using.
5. Removing snowfall as soon as possible
produces the best results.
6. To obtain the greatest performance
from snow thrower, place vanes in a
vertical position, discharge snow down­
wind and overlap each pass slightly.
7. The type of snow you are throwing
will dictate to you how to use this
machine. In light, fluffy snow the unit
will propel itself if tilted forward slightly
(lifting up on handle - as shown below)
allowing the impeller paddles to contact
the ground. In heavy wet snow the unit
will propel itself forward without tilting.
NOTE; The depth and weight of snow to
be cleared will control forward speed of
snow thrower.
8. In heavy, wet snow overlapping is
essential to prevent overloading. Permit
machine to work at a slow pace. If engine
slows down due to overloading, pull
unit back out of snow and/or release
auger clutch control (if so equipped)
until engine regains full power. Then
allow machine to propel itself back into
snow.
