Caution:
• Be sure to check the block (front, rear) for melting, thermal deformation, cracking, or discoloration caused by leakage.
If found, be sure to replace it with a new one without delay.
• Be sure to check and clean the block (front, rear) thoroughly (all the way to its inside).
• Never use a cloth carrying any metal powder.
• Unless specifically indicated, do not use a moist cloth. Use lint-free paper to dry wipe, and use alcohol thereafter. Be sure
that the alcohol has completely evaporated before fitting the part back into the machine.
• Be sure to provide scheduled servicing and replace periodically replaced parts at specific intervals.
