6 - 26
• BOOM SLIDING PADS (EXTERNAL)
-
Fully extract the telescopic boom
- Carefully clean the boom sliding surface, taking away the residual grease
- With the help of a cotton wad, evenly spread a thin layer of grease (see
chapter "FUELS AND LUBRICANTS) on the entire boom sliding surface
- Carry out a few boom extraction and retraction cycles, so as to evenly
distribute the product.
WARNING!
It is possible to use only the recommended product; a different product
could cause serious damages to the sliding surface of the boom. When using the machine in particularly demanding
conditions it is necessary to grease more frequently.
• AIR VENTILATION FILTER
Replace the cab ventilation system filter as follows:
-
Unscrew fastening screws "V"
- Extract the cab ventilation filter
- Replace the filter with a new one with the same features
- Mount back the filter tightening fastening screws "V".
• HYDRAULIC PIPES/HOSES
Perform the following checks on the hydraulic pipes/hoses:
1) visual check for any oil leakage
2) visual check for any marks on the hydraulic pipes/hoses which might be
indicative of future oil leakage (picture 1)
3) visual check for any mechanical scraping or graze on the external protection
of the hydraulic pipes/hoses (picture 2)
Should any of the conditions above be met, replace the faulty pipe/hose as soon
as possible, so as to prevent the problem from getting worse.
NOTE! Pictures 1 and 2 show some examples of problems which
might occur on hydraulic pipes/hoses.
