8.3.5 Ball bearing ring
The grease filling is to avoid friction, and to provide sealing
and protection against corrosion. Therefore, the ring must
be lubricated every 10 operating hours until grease
becomes visible on the outside. Swivel the bucket arm in
steps of 20° while lubricating the ball bearing ring and make
sure to inject grease in each of the four grease nipples
(8-35/arrows). It is absolutely necessary to lubricate the
machine before and after a longer period of inactivity.
DANGER
- Before you start lubricating, insert the bucket arm
support (1-1/arrow), apply the parking brake
(4-10/8) and set the drive direction switch (4-10/3)
to the "0" position.
- During swiveling, no-one may be present in the
swivel area of the bucket arm.
