GENERALITIES

WARNING !

Perform maintenance operations having the engine

stopped and cold. Get the the starting key out from the

panel, put it in your pocket and turn off the power supply.

Read this whole chapter and take all safety precautions

before contemplating any maintenance or repair work.

Make sure you understand how to perform every

operation.

CAUTION !

Clean the engine before any maintenance. Watch for any

oil or fluid drop as it is an evidence of a leak somewhere.

CAUTION !

Do not let oil, fuel or grease deposits build up around

the engine as they may increase the risk of fire in the

engine compartment. Furthermore, these deposits may

hide potential heavy unseen failures.

CONTROL CABLES

The engine rpm and the gearbox shift command may be

controlled by mechanical control cables connected to

the control lever.

Adjust the tightness of the cable as required. If any

defect appears (rust, crack, etc.), the control cable must

be replaced.
