and add correct amount of engine oil to bring oil level to
a normal safe level. Use oil as recommended in Figure 6

Handle fuel safely. Motor fuels are highly
flammable and can be dangerous if
mishandled. DO NOT smoke while

running. DO NOT attempt to start the engine until the
fuel residue has been completely wiped up and the
area surrounding the engine is dry.
