4.1.1 Introduction
Make preparation as follows before starting engine inspection and service:
1) Fix the engine on a horizontal base.
Be sure to fix the engine securely to prevent injury or damage to parts due to falling during the work.
2) Remove the coolant water hose, fuel oil pipe, wire harness, control wires etc. connecting the
driven machine and engine, and drain coolant water, lubricating oil and fuel.
3) Clean soil, oil, dust, etc. from the engine by washing with solvent, air, steam, etc. Carefully
operate so as to prevent any foreign matter from entering the engine.
Always wear glasses or other protectors when using compressed air or steam to prevent any foreign
matter from getting in the eyes.
[NOTICE]
Any part which is found defective as a result of inspection or any part whose measured value does
not satisfy the standard or limit shall be replaced.
Any part predicted to dissatisfy the standard or limit before the next service as estimated from the
state of use should be replaced even when the measured value then satisfies the standard or limit.
