6. Do not change engine governor settings.
7. Do not put hands near rotating parts for any
reason.
8. If the power vacuum should start to vibrate
abnormally, stop the engine and check immedi
ately for the cause. Vibration is generally a
warning of trouble.
9. Before cleaning, repairing or inspecting, make
certain all moving parts have come to a complete
