ImpoRTaNT
Polyurea and lithium-based greases are not compatible.
Mixing the two grease types may lead to premature
failure.
NoTE
Do not over grease bearings. Overfilling can lead to
excessive heat and/or unseating of the seals. Add
grease slowly and under light pressure. Whenever
possible, rotate bearing slowly while lubricating.
lubricate the machine periodically with a lithium-based
grease. Extreme working conditions will require more
frequent greasing.
