Disassembly
WARNING: Accidental Starts!
Disabling engine. Accidental starting can cause severe injury or death. Before working on the engine or equipment,
’œŠ‹•Žȱ‘ŽȱŽ—’—ŽȱŠœȱ˜••˜ œDZȱŗǼȱ’œŒ˜——ŽŒȱ‘Žȱœ™Š›”ȱ™•žȱ•ŽŠǻœǼǯȱŘǼȱ’œŒ˜——ŽŒȱ—ŽŠ’ŸŽȱǻȬǼȱ‹ŠĴŽ›¢ȱŒŠ‹•Žȱ›˜–ȱ‹ŠĴŽ›¢ǯ
Clean all parts thoroughly as the engine is
disassembled. Only clean parts can be accurately
inspected and gauged for wear or damage. There
are many commercially available cleaners that will
quickly remove grease, oil and grime from engine
parts. When such a cleaner is used, follow the
manufacturer’s instructions and safety precautions
carefully.
Make sure all traces of the cleaner are removed before
the engine is reassembled and placed into operation.
Even small amounts of these cleaners can quickly
break down the lubricating properties of engine oil.
