Appendix. Grease Contamination: Causes and Measures
6.1
Causes
Causes for contamination can be divided into two categories.
（
1
）
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.)
（
2
）
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.)
6.2
Measures
（
1
）
Clean the tank and remove the foreign particles.
（

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.
