Risk of accident
from vehicle starting off by itself when engine running. Risk of injury
(bruises and burns) resulting from working on the engine while it is being started or when it is running. Perform an engine test run and check exhaust system for leaktightness |
Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | AS00.00-Z-0005-01A |
