Lubrication & Oiling Plan - PTO

The amount of grease to be applied is mentioned in grams (g). Test your grease gun to see how many grams it provides, for
example after 5 strokes.

ATTENTION! The correct amount of grease applied at the intervals is important. Too little or too much grease will
shorten the lifetime of the PTO.

The grease points and amount of grease to be applied are shown in the pictures below together with the intervals.
