5.5 LUBRICATION
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.
NOTE
Polyurea and lithium-based greases are not
compatible. Mixing the two grease types may lead to
premature failure.

engagement handle and both models have grease zerks
located at the base of the discharge tube. Lubricate the
machine periodically with a lithium-based grease. Extreme
working conditions will require more frequent greasing.
