EMISSIONS CONTROL Maintenance, replacement, or repair of the emissions control devices and systems may be performed by any non-road engine repair establishment or indiv-However, to obtain a "no charge" emissions control service, the work must be performed by a factory authorized dealer. See the Emissions Warranty. GENERAL RECOMMENDATIONS The warranty on this snowthrower does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the snow thrower as instructed in this manual. ENGINE POWER RATING INFORMATION The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual "on-site" or net power). This difference to due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine. 1741506 19 MAINTENANCE AFTER EACH USE • Check for any loose or damaged parts. • Tighten any loose fasteners. • Check and maintain the auger. • Check controls to make sure they are functioning properly. • If any parts are worn or damaged, replace immediately. • Check all safety and instruction decals and labels.
