9 FUEL HANDLING PROPER FUEL T aking the following precautions will lessen the risk of injury and property damage: - Use extreme care in handling gasoline. It is extremely ammable and the vapors are explosive. - Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
10 Engine Oil Checking, Adding and Changing Oil Check the engine oil level (B) daily with saw fully lowered and the engine level. See the enclosed Robin manual for more details. Use SAE 10W-30 viscosity detergent automotive type with API service class SE or higher grade oil.
11 As concrete hydrates or cures and begins to set, it develops internal stresses which may cause random cracks. Random cracks cast doubt on the quality and workmanship of the concrete. Contraction joints are cut in concrete to relieve these stresses before they seek their own relief in the form of random crack.
12 “ The timing of concrete operations - especially nishing and jointing - is critical” , states a quote from the foreword of the American Concrete Institute (ACI) 302.1 R-96. It goes on to say that “Failure to address this issue can contribute to unde- sirable characteristics in the wearing surface as cracking.
13 TROUBLESHOOTING ENGINE RUNS ROUGH, BACK FIRES OR CAN NOT REACH FULL SPEED - Check if there is fuel in the tank and it is the correct fuel. Make sure there is no water in the fuel. - Check that the spark plugs are clean and properly gapped. - Check that choke is in the “off” position after engine is warm.
