
The telescopes of the boom are guided by gliders. In order to have a
possibly low wear and slippage resistance a lubrication of the gliding
surfaces becomes necessary in intervals according to the maintenance
list (or depending on the use also earlier
)
.
Extend the telescope for lubrication (greasing) as far as possible and
grease the gliding surfaces („G“) slightly, e.g. by means of a radiator
paint brush.
Note
Do not grease too much to avoid an accumulation of
grease inside the booms.

Regrease extension ropes according to inspection list. Therefore re-
move inspection apertures („I
1
“ to „I
3
“) at the corresponding boom head
(left and right). You can additionally also demount the scraper (brushes)
at boom head. As long as there is a sufficient grease film on the rope, a
regreasing is unnecessary. The lubricant should be liquid at the begin-
ning, to ensure that it can penetrate into the rope between the rope
strands and wires. During greasing procedure extend or retract the tele-
scope. Do not overgrease the ropes.
Attention!
Do not grease the polyester slide bearings of the rope
pulleys in the boom system or do not wet them with
oil!

Grease retraction chains according to maintenance list. There must be
no dirt at the outside of the chain. For an effective lubrication a sufficient
quantity of lubricant must be brought into the chain links or joints during
each lubrication procedure.
