wire, and keep the wire away from the plug to prevent

and for moving the snowthrower in or out of the
building. Open the outside doors; exhaust fumes are
dangerous.

plates or other safety protective devices in place.

clear snow at too fast a rate.

Never operate the machine at high transport speeds on
slippery surfaces. Look behind and use care when
moving in reverse.

Never direct discharge at bystanders or allow anyone
in front of the unit.

Disengage power to the collector (auger/rotor
blades)/impeller when snowthrower is transported or
not in use.

manufacturer of snowthrower (Lawn-Boy), such as
wheel weights, counterweights, cabs, etc.  (Refer to
your Authorized Service Dealer for accessories
available for your snowthrower.)

Never operate the snowthrower without good visibility
or light.  Always be sure of your footing, and keep a
firm hold on the handles. Walk; never run.

Maintenance and storage

Check all fasteners at frequent intervals for proper
tightness to be sure the equipment is in safe working
condition.

Never store the machine with fuel in the fuel tank
inside a building where ignition sources are present
such as hot water and space heaters, clothes dryers,
etc.  Allow the engine to cool before storing in any
enclosure.

Always refer to this operator’s manual for important
details if the snowthrower is to be stored for an
extended period.

Maintain or replace safety and instruction labels, as
necessary.

Run the machine a few minutes after throwing snow to
prevent freeze-up of the collector (auger)/impeller.
(With the engine running, pull the recoil starter handle
several times.)

Lawn-Boy Snowthrower Safety

The following list contains safety information specific to
Lawn-Boy products or other safety information that you
must know that is not included in the ANSI or ISO
standards.

The rotating impeller or auger can cut off or injure
fingers or hands.
  Stay behind the handles and away
from the discharge opening while operating the
snowthrower.  Keep your face hands, feet, and any
other part of your body or clothing away from
concealed, moving, or rotating parts.

Before adjusting, cleaning, repairing, and inspecting
the snowthrower, and before unclogging the discharge
chute, stop the engine, remove the key, and wait for
all moving parts to stop
.  Also, pull the wire off of
the spark plug and keep it away from the plug to
prevent accidental starting.

Use a stick, not your hands to remove obstructions
from the discharge chute.

Before leaving the operator’s position behind the
handles, stop the engine, remove the key, and wait for
all moving parts to stop.

Do not wear loose fitting clothing that could possibly
get caught in moving parts.

If a shield, safely device, or decal is damaged,
illegible, or lost, repair or replace it before beginning
operation.  Also, tighten any loose fasteners.

Do not smoke while handling gasoline.

For two-stage snowthrowers, use the lower gear and, if
applicable, the rear wheel position when operating on
slopes.

Do not use the snowthrower on a roof.

Do not touch the engine while it is running or soon
after it is stopped because the engine will be hot
enough to cause a burn.  Do not add oil or check the
oil level in the crankcase when the engine is running.

Perform only those maintenance instructions described
in this manual. Before performing any maintenance,
service, or adjustment, stop the engine, remove the key
and pull the wire from the spark plug, keeping it away
from the plug to prevent accidental starting.  If major
repairs are ever needed, contact your Authorized
Lawn-Boy Service Dealer.

Do not over speed the engine by changing the
governor settings.
