Tune-Up Notes
NOTE:
When performing tune-up procedures described in this article, these notes and precautions must be followed.
Due to late changes and corrections, always refer to Emission Control Label in engine compartment before attempting tune-up. If label specifications are different than specifications presented here, use label specifications.
Adjustment of injectors or internal adjustment of injection pump must be done in a properly equipped injector shop with clean environment.
Prior to checking compression, ensure battery is fully charged to avoid battery run down. Crank engine through at least 6 compression strokes before recording reading.
CAUTION:
DO NOT add oil to cylinders for a wet compression test. The high compression ratio could cause damage to engine or oil could ignite and cause serious bodily harm.
