4.2 Point to Note on Scheduled Servicing
Notes:
Make thorough checks to be sure that the block (front, rear) is free of melting, thermal deformation, cracking, or yellowing caused by leakage. If a fault is found, replace the part immediately.
Make checks and clean as far as the inside of the block (front, rear).
Do not use a cloth or the like carrying metal powder.
Do not use a wet/moist cloth unless specifically indicated. Use lint-free paper to dry wipe, and then use alcohol. After using alcohol, check to make sure that the part has dried completely.
Provide scheduled servicing and replacement at the specified intervals.
