Product Specifications - Craftsman 917.370721 Owner's Manual

• Never fi ll containers inside a vehicle, on
a truck or trailer bed with a plastic liner.
Always place containers on the ground
away from your vehicle before fi lling.
• Remove gas-powered equipment from
the truck or trailer and refuel it on the
ground. If this is not possible, then
refuel such equipment with a portable
container, rather than from a gasoline
dispenser nozzle.
• 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.
• If fuel is spilled on clothing, change
clothing immediately.
• Never overfi ll fuel tank. Replace gas
cap and tighten securely.
V. GENERAL SERVICE
• Never run a machine inside a closed
area.
• Never make adjustments or repairs with
the engine (motor) running. Dis con nect
the spark plug wire, and keep the wire
away from the plug to prevent ac ci den tal
starting.
WARNING: This lawn mower is equipped with an internal com bus tion engine and
should not be used on or near any un im proved forest-covered, brush-covered or
grass-cov ered land unless the engine's exhaust system is equipped with a spark
arrester meeting applicable local or state laws (if any). If a spark arrester is used, it
should be maintained in effective working order by the operator.
In the state of California the above is required by law (Section 4442 of the California
Public Resources Code). Other states may have similar laws. Federal laws apply on
federal lands. A spark arrester for the muffl er is available through your nearest Sears
Parts & Repair Center (See the REPAIR PARTS section of this manual).
