Power Ratings: The gross power rating for individual petrol engine models is labeled in accordance with SAE (Society of Automotive Engineers) code
J1940 Small Engine Power & Torque Rating Procedure, and is rated in accordance with SAE J1995. Torque values are derived at 2600 RPM for those
engines with "rpm" called out on the label and 3060 RPM for all others; horsepower values are derived at 3600 RPM. The gross power curves can be
viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken with exhaust and air cleaner installed whereas gross power values are
collected without these attachments. Actual gross engine power will be higher than net engine power and is affected by, among other things, ambient
operating conditions and engine-to-engine variability. Given the wide array of products on which engines are placed, the petrol engine may not develop
the rated gross power when used in a given piece of power equipment. This difference is due to a variety of factors including, but not limited to, the
variety of engine components (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 engine.
* This water pump is rated in accordance with Briggs & Stratton standard 621K.

Correction
1. Fill pump chamber with water and prime pump.
2. Replace suction or discharge hose.
3. Sink the strainer and the end of suction hose
completely under water.
4. Replace sealing washer if missing or damaged.
Tighten hose connector and clamp.
5. Clean debris from strainer.
6. Relocate pump and/or hoses to reduce head.
7. Move engine speed lever to FAST position.
1. Set switch to ON (I).
2. Turn fuel shutoff to ON (I) position.
3. Clean or replace air cleaner.
4. Wait two minutes and fill fuel tank.
5. Drain fuel tank and carburetor; fill with fresh
fuel.
6. Connect wire to spark plug.
7. Replace spark plug.
8. Wait 5 minutes and re-crank engine.
9. Contact Authorized service facility.
Wait two minutes and fill fuel tank.
