General Recommendations

1.The owner’s responsibility is to maintain this product. This will extend the life of the product and is also necessary to maintain warranty coverage.

2.Check the spark plug, drive brake, lubricate the unit, and clean the air filter once a year.

3.Check the fasteners. Make sure all fasteners are tight.

4.Follow the Maintenance section to keep the unit in good operating condition.

WARNING

Before you make an inspection, adjustment, or repair to the unit, disconnect the wire to the spark plug. Remove the wire from the spark plug to prevent the engine from starting by accident.

NOTE: Torque is measured in foot pounds (metric Nm). This measurement describes how tight a nut or bolt must be.The torque is measured with a torque wrench.

Engine Power Rating

The gross power rating for individual gas engine mod- els is labeled in accordance with SAE (Society of Auto- motive 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 af- fected by, among other things, ambient operating con- ditions 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 de- velop the rated gross power when used in a given piece of power equipment (actual "on-site" or net power). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charg- ing, 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.

Inspect the Blade

WARNING

Before you inspect or remove the blade, disconnect the wire to the spark plug. If the blade hits an object, stop the engine. Check the unit for damage. The blade has sharp edges. When you hold the blade, use gloves or cloth material to protect your hands.

If you keep the blade sharp and inspect the blade for damage, the blade will cut better and be more safe to operate.

Frequently check the blade (1) for excessive wear, cracks, or other damage (see Figure 21).

Frequently check the nuts (2) that hold the blade. Keep the nuts tight.

If the blade hits an object, stop the engine. Dis- connect the wire to the spark plug. See if the blade is bent or damaged.

Before you operate the unit, replace damaged parts with original equipment parts. See the authorized serv- ice center in your area. Every three years, have an au- thorized service person inspect the blade or replace the old blade with an original equipment part.
