WARNING: In general it is not recommend to mix greases of different brands. The mixing of different types of thickeners may destroy the
composition and physical properties of the grease. In the event that a different grease is required by the end user, the following steps can
be taken. Using the instructions for lubrication, open grease outlet and purge the system as much as possible of the old or unwanted
grease. Repeat this same operation after 1 week of service. Consult TOSHIBA/HOUSTON Engineering for further recommendations on
grease compatibility.
