Hoses inspection - Replacement
1 - You will need
• Standard tool kit
• Protective goggles
• Gloves
Exclusively use tools and auxiliary average adapted. Always wear necessary safety clothing.
2 - Control and inspections
The state of hoses devices plays a significant role in the safety of the machines.
Section D - Inspection and maintenance schedule :
• Check the absence of leakage to the junctions of the hoses.
• Check that all the hoses are correctly tightened.
• Check the absence of tear and crack of the external hoses.
• Check that the shielding of the hose is not apparent.
• Check the absence of chemical aggression of the membrane of the hose.
If anomalies are noted, it is necessary to replace the elements by respecting the following recommendations.
3 - Hoses Disassembling
For safety reasons, respect imperatively the following conditions of disassembling :
• Fold the machine on a flat and released ground :
• The machine is not in slope.
• The boom is horizontal.
• Put the turret (if equipped) in the axis.
• Carry out a beaconing of the sector (maximum risk zone = machine height).
• Locate the hoses and their connections points to guarantee the good performance of the machine after intervention.
• Locate the hoses course to facilitate the reassembly.
To recover oil, use an oils container in order not to pollute the environment.
Unscrew the flexible device slowly in order to make fall residual water pressure.
It is imperative to secure and maintain cylinders when removing hoses cylinders. An analysis of the
hydraulic system is imperative.
After disassembling :
• Close the hose openings and the hydraulic components to avoid the pollution of the hydraulic system.
• Check the cleanliness of the hoses and the hydraulic components :
• Absence of plastic, rubber or metal shaving.
• If necessary, purge and clean the circuit (tank included).
