BOOM SLIDING BLOCKS
Lubrication
(g.80/D)
The boom sliding blocks must be kept lubricated to avoid
wear and keep movements smooth.
Completely extend the boom and inspect its surface. If
the layer of lubricant is thin or with impurities (sand, dust,
sawdust, etc.) act as follows:
- While the boom is completely extended horizontally, remo-
ve the layer of lubricant from the extensions with a cloth.
- Use a brush to apply a layer of lubricant of the approved
type on the four sides of the telescopic boom.
- Activate the boom several times to distribute the lubri-
cant evenly.
- Remove any excess lubricant.
- CAUTION -
During the visual inspection and while applying the
lubricant, the machine must be switched off and the key
removed from the cab to avoid accidental manoeuvres.
- CAUTION:
If the machine is used in extreme conditions or in very dusty
environments, lubricate more often.
- CAUTION:
Only use the lubricants indicated in the DIECI tables. Different
lubricants can cause serious damage to the sliding surfaces.
Sliding block wear
Consult the summary table at the start of this chapter to nd
out how often this must be done.
Worn sliding blocks can cause oscillations and bac-
klash between one extension and another with a conse-
quent loss of precision and danger of dropping the load.
The more extreme the working conditions, the greater the
wear. Any maintenance work carried out on the boom sliding
blocks must be carried out by an authorised service centre.
