explosive. Handle with care. Use an approved fuel
container. DO NOT smoke or allow open flame
(match, pilot light, etc.) or sparks near equipment
or fuel container when refueling or servicing fuel
system.

Use non-flammable solvent to clean parts - DO NOT
use gasoline.

Use only Ariens original replacement parts when
making repairs.

After all repair procedures are performed, make sure
that unit is in good operating condition and all
safety devices and shields are in place and in good
working condition. Be sure all fasteners are tight,
all adjustments are correct and all tools are removed.

To prevent accidental starting, disconnect wire to
spark plug(s) and position wire away from plug.

Always wear safety goggles when cleaning or making
repairs to parts or machine.
