Appendix. Grease contamination:

Causes and measures

■

Causes

Causes for contamination can be divided into two categories.

○

Before the completion of installation

Foreign particles in the tubing or pump tank.

(Manufacturing defects of the assembly parts or
connecting parts and unconformity during construction.)

○

During operation

Foreign particles from outside or generated inside of the
system.

(Condensation of the moisture in the air due to change in
temperature or separation of grease ingredients.)

■

Measures

．

At the time of cartridge exchange, connection mouth

not

stick the foreign particles attention enough.

．

Keep the grease for refilling in the proper place.

If the system is installed and/or grease is stored outdoor,

proper care must be taken since introduction of dust or
rain into the grease would lead to system malfunction.
