Carburetor

if you think your carburetor needs adjusting, see your nearest Sears service center. Engine performance may be affected at altitudes above 3000 feet. For operation at higher elevations, contact your nearest Sears service center.

Spark Arrester Service

Your engine is not factory-equipped with a spark arrester. In some areas, it is illegal to operate an engine without a spark arrester. Check local laws and regulations. A spark attester is available from your nearest Sears service center. If you need to order a spark arrester, please call 1-800-366-PART.

The spark arrester must be serviced every 50 hours to keep it functioning as designed.

If the engine has been running, the muffler will be very hot. Allow the muffler to cool before servicing the spark arrester.

•Remove spark attester screen for cleaning and inspection.

•Replace if screen is damaged.

VVARNING

DO NOT touch hot surfaces.

Allow equipment to coo! before touching.

The pressure washer must be at least 5 feet from

structures having combustible walls and/or other

combustible materials.

Keep at least 3 feet of clearance on all sides of pressure

washer for adequate cooling, maintenance and servicing.

in the State of California a spark arrester is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. If you equip the muffler with a spark attester, it must be maintained in effective working order.

Air Coo_ing System

Over time debris may accumulate in cylinder cooling fins and cannot be observed without partial engine

disassembly. For this reason, we recommend you have an authorized Sears service dealer clean the

cooling system per recommended intervals (see "Maintenance Schedule" on page 13). Equally important is to keep top of engine free from debris. See "Clean Debris".
