NOTICE:
• Never mix greases of different consistencies (NLGI 1 or 3 with NLGI 2) or with different thickeners.
For example, never mix a lithium-based grease with a polyurea-based grease. Doing so may result in
decreased performance.
• Remove the bearings and old grease if you need to change the grease type or consistency. Failure to
do so may result in equipment damage or decreased performance.
Use a grease that is suitable for high temperatures when you have frame pumpage temperatures greater
than 350°F (177°C). Ensure that mineral-oil greases have oxidation stabilizers and a consistency of NLGI
3.
