PREOPERATING CHECKLIST

Before operating the mower for the first time, and as a routine before daily operations, it is important to make sure the mower is properly prepared and ready for operation. The following is a list of items to be checked. (For a mower with frequent operation, some of these items will not need to be checked every day, but the operator should be aware of the condition of each.)

For proper fuel and lubricants refer to Specifications.

Handle gasoline with care. Gasoline is highly flammable and its vapors are explosive. Use safe refueling procedures:

· DO NOT fill fuel tank with the engine running.

· If the engine is hot, allow to cool before refueling.

· Use an approved fuel container.

· Fuel the mower outdoors.

· DO NOT smoke while refueling.

· Avoid spilling fuel; use a funnel or spout.

· DO NOT overfill the fuel tank; fill up to about 1 in. (25 mm) below the top of tank.

IMPORTANT: DO NOT permit dirt or other foreign matter to enter the fuel tank. Wipe dirt from around the filler cap before removing. Use a clean fuel storage container and funnel.

IMPORTANT: DO NOT mix oil with gasoline. Always use fresh, automotive grade unleaded gasoline. DO NOT use premium, white, or high-test gasoline. DO NOT use additives, such as carburetor cleaners, deicers, or moisture removing agents.

DO NOT use gasoline blended with methyl alcohol.
