carelessness or error on the part of the operator can result in serious
injury. This machine is capable of amputating hands and feet and
throwing objects. Failure to observe the following safety instructions
could result in serious injury or death.
Safe Handling of Gasoline
To avoid personal injury or property damage use extreme care in handling
gasoline. Gasoline is extremely flammable and the vapors are explosive.
Serious personal injury can occur when gasoline is spilled on yourself or your
clothes, which can ignite. Wash your skin and change clothes immediately.
a. Use only an approved gasoline container.
b. Extinguish all cigarettes, cigars, pipes and other sources of ignition.
c. Never fuel machine indoors.
d. Never remove gas cap or add fuel while the engine is hot or running.
e. Allow engine to cool at least two minutes before refueling.
f. Never over fill fuel tank. Fill tank to no more than ½ inch below bottom
of filler neck to provide space for fuel expansion.
g. Replace gasoline cap and tighten securely.
h. If gasoline is spilled, wipe it off the engine and equipment. Move
machine to another area. Wait 5 minutes before starting the engine.
i. Never store the machine or fuel container inside where there is an open
flame, spark or pilot light (e.g. furnace, water heater, space heater,
clothes dryer etc.).
j. Allow machine to cool at least 5 minutes before storing
k. Never fill containers inside a vehicle or on a truck or trailer bed with a
plastic liner. Always place containers on the ground away from your
vehicle before filling.
l. If possible, remove gas-powered equipment from the truck or trailer and
refuel it on the ground. If this is not possible, then refuel such equip-
ment on a trailer with a portable container, rather than from a gasoline
dispenser nozzle.
m. Keep the nozzle in contact with the rim of the fuel tank or container
opening at all times until fueling is complete. Do not use a nozzle
lock-open device.
OPERATION
1. Do not put hands or feet near rotating parts, in the auger/impeller housing
or chute assembly. Contact with the rotating parts can amputate hands
and feet.
2. The auger/impeller control lever is a safety device. Never bypass its
operation. Doing so makes the machine unsafe and may cause personal
injury.
3. The control levers must operate easily in both directions and automatically
return to the disengaged position when released.
4. Never operate with a missing or damaged chute assembly. Keep all safety
devices in place and working.

SAFETY INSTRUCTIONS
5. Never run an engine indoors or in a poorly ventilated area. Engine exhaust
contains carbon monoxide, an odorless and deadly gas.
6. Do not operate machine while under the influence of alcohol or drugs.
7. Muffler and engine become hot and can cause a burn. Do not touch.
8. Exercise extreme caution when operating on or crossing gravel surfaces.
Stay alert for hidden hazards or traffic.
9. Exercise caution when changing direction and while operating on slopes.
10. Plan your snow-throwing pattern to avoid discharge towards windows,
walls, cars etc. Thus, avoiding possible property damage or personal
injury caused by a ricochet.
11. Never direct discharge at children, bystanders and pets or allow anyone in
front of the machine.
12. Do not overload machine capacity by attempting to clear snow at too fast
of a rate.

OPERATION
REPLACING SHEAR PINS
The augers are secured to the spiral shaft with shear pins and cotter
pins. If the augers 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. See Figure 20.
CAUTION
NEVER replace the auger shear pins with anything other than Sears
SKU# 88389/OEM Part No. 738-04124A replacement shear pins.
Any damage to the auger gearbox or other components as a result of
failing to do so will NOT be covered by your snow thrower’s warranty.
WARNING
Always turn off the snow thrower’s engine and remove the key prior to
replacing shear pins.
