h Chapter 7.8.3 Maintenance and inspection plan
Defective lubrication nipples may result in bearing damage. Replace damaged lubrication nip-
ples immediately and check to ensure grease is passing through them. Following mainte-
nance work, manually lubricate a lubricating point until grease escapes.
Danger of injury due to falling
• Before greasing the machine, apply the outriggers and lower the loading equipment (boom
in horizontal position).
• The grab must be lubricated separately as described in the operating instructions supplied
with the grab.
In an emergency: Administer first aid, seek treatment from a doctor
