Fuel spray prevention caps (1) - (16) and fuel spray prevention cover (17) are protective parts installed to prevent
fire caused by fuel leaking and spraying out on to high temperature parts of the engine. Check visually that there
are no missing caps or loose bolts, and feel with your finger to check that the rubber has not hardened. If there is
any problem, the problem part must be replaced. In such a case, please contact your Komatsu distributor.
