Sears 917.370721 Product Specifications, V. General Service, BRIGGS & STRATTON 4-CYCLE ENGINE

•Never fill 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 filling.

•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 overfill 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. Disconnect the spark plug wire, and keep the wire away from the plug to prevent accidental starting.

•Keep nuts and bolts, especially blade attachment bolts, tight and keep equip- ment in good condition.

•Never tamper with safety devices. Check their proper operation regularly.

•Keep machine free of grass, leaves, or other debris build-up. Clean oil or fuel spillage. Allow machine to cool before storing.

•Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting.

•Never attempt to make wheel height adjustments while the engine is running.

•Grass catcher components are subject to wear, damage, and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace with manufacturer’s recommended parts, when necessary.

•Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when servicing them.

•Do not change the engine governor set- ting or overspeed the engine.

•Maintain or replace safety and instruc- tion labels, as necessary.

WARNING: This lawn mower is equipped with an internal combustion engine and should not be used on or near any unimproved forest-covered, brush-covered or grass-covered 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 muffler is available through your nearest Sears Parts & Repair Center (See the REPAIR PARTS section of this manual).
