Greasing Bearing
The service life of bushings and pivot pins can be extended
considerably, if the machine is greased regularly and in the
correct way.
The greasing of bearings has two main purposes:
• Add grease to the bearing to reduce friction between
pin and bushing.
• Replace old grease which may contain dirt. The
grease in the space inside the outer seal collects dirt
and prevents dirt and also water from penetrating into
the bearing.
Therefore, grease the bearing until new, clean grease is forced
out through the outer seal.
Between 10 and 15 strokes with a normal handheld grease gun
is required to grease one of the bearings for the lifting arms.
Wipe off grease fittings and grease gun before greasing, so that
dirt and sand is not introduced through the grease fittings.
