Disconnect Spark Plug Leads; Drain Oil From Crankcase And Remove Oil Filter; Remove Muffler; Remove Cylinder Shrouds And Blower Housing - Kohler Command PRO EFI Series Service Manual

Disassembly/Inspection and Service
Clean all parts thoroughly as 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 manufacturer's instructions and
safety precautions carefully.
Make sure all traces of cleaner are removed before
engine is reassembled and placed into operation. Even
small amounts of these cleaners can quickly break down
lubricating properties of engine oil.
NOTE: This disassembly sequence removes some
components in subassemblies to enable
technician to perform internal engine servicing.
Do not disconnect every EFI and electronic
governor component.

Do not fi ll fuel tank while engine is hot or
running.
Gasoline is extremely fl ammable and its vapors can
explode if ignited. Store gasoline only in approved
containers, in well ventilated, unoccupied buildings,
away from sparks or fl ames. Spilled fuel could ignite
