6 - ORDINARY MAINTENANCE
6 - 25
• BOOM SLIDING PADS (EXTERNAL)
- Fully extend the telescopic boom
- Carefully clean the boom sliding surface, removing the residual grease
- Using a cotton wad, evenly spread a thin layer of grease (see paragraph
"FUELS AND LUBRICANTS") over the entire boom sliding surface
- Carry out a few boom extension and retraction cycles so as to evenly
distribute the product.
WARNING!
Only the recommended product can be used; a different product could
cause serious damages to the sliding surface of the boom. More frequent
greasing is required when using the machine in particularly demanding
conditions.
By way of example only, the boom of a P40.17 PLUS machine (3
extensions) is shown. Perform the same operations for the telescopic
boom on your machine (1 or 2 extensions depending on the model).
• AIR VENTILATION FILTER
Replace the filter of the cab ventilation system as follows:
- Unscrew fastening screws "V"
- Extract the cab ventilation filter
- Replace the filter with a new one with the same features
- refit the filter, tightening the fastening screws "V"
• HYDRAULIC HOSES
Perform the following checks on the hydraulic hoses:
1) visual check for any oil leaks
2) visual check for any marks on the hydraulic hoses which might be indicative of
future oil leaks (photo 1)
3) visual check for any mechanical scraping or grazing on the external protection of
the hydraulic hoses (photo 2)
Should any of the conditions above occur, replace the defective hose as soon as
possible, so as to prevent the problem from getting worse.
NOTE! Photos 1 and 2 show some examples of problems which might
occur on hydraulic hoses.
