o ) IMPORTANT FUEL SYSTEM SAFETY WARNING AND ANNOUNCEMENT OF FREE, REPLACEMENT GASOLINE CAP A CAUTION! The following information pertains to personal salety. Be sure to read and follow these instructions. PROBLEM - Gasoline vapors can build up pressure in your gasoline tank. All gasoline fuels are more volalile today than ever before. They vaporize and build up pressure in your gasoline tank more easily than in the past. Winter grade gasoline is especially subject to va· porizalion and pressure build·up when used on hot Spring or Fall days. If you have a tractor wh ich is out of tun(' or not properly maintained. it Ciln run honer and increase vaporization. DANGER - Fire and personal injury. If the fuel cap is removed when the gasoline lank is hoi and vapor pressure has, under cenain circum· stances. built up in the tank, this sudden release of pressure could force gasoline out of the tank. If the gas cap is not fully secured and tightened, it could come off the tank. and again, gasoline could es· cape. This sudden eruption of gasoline exposes ttU:l operator to, and may cover him with. liqUid fu~t and va~ors and IS a ctear fife hazard if a source of ignition is present. A running engine is a sourc!! of ignition. as arC' Clg3retteS. open flames. sparks or a poorfy maullmned exhaust syst!!m. An immediate fire could occur . The operator or anyone In the ama couleJ be hurned and suffer serious illJUry or evc~ n d( !ilth. PRECAUTIONS - Observe the following steps for safe operation: - Always tighten gas caps securely. - Never. under any circumstances. take the gas cap off a hot or running tractor. - Never hold over Winter gasoline for 'USE> In thl' Spring. Remove any eqUlpmenJ unnecessary for warm weather operations. such as com ion covers. heilt housers. or radiator covers. -- Maintain equipment properly and pay partlcul~r aMention to electrical. exhaust. fuel. and coolIng systems. Repair or replace frayed electrical wires: leaky exhaust manifolds. gaskets. pIpes and muffters: damaged carburetors. sedlmen: bowls and fuel lines. Be sure radiators are clean inside and out. Ctean off any accumulation of trash. oil or grease. - Make sure that fuel cap vent holes are not plugged. gaskets are in good condition. and that cap tangs are firmly riveted. Repair worn. bent. or deformed filler necks and damaged heat shields or shield insulation. If your tractor is not equipped with a heat shield or insulation. install such equi~ment on applicable models. -- Be aten to any unusual sights and sounds dur- ing operution. If you suspecl overheating or pressure build-up in the fuel system. do not touch the cap. Turn oH the engine and allow the trar:tor to cool before you toucllthe cap.
