1 - You will need
2 - Control and inspections
The state of hoses devices plays a significant role in the safety of the machines.
For the hoses device accessible without consequent disassembling, a visual inspection must be realized all the 250
hours or 1 year :
• 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.
For the non visible hoses without disassembling, a reinforced visual inspection must be realized all the 5000 hours
or 5 years.
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.
• Standard tool kit
• Protective goggles
• Gloves
• Place barriers around the perimeter of the work area
Exclusively use tools and auxiliary average adapted. Always wear necessary safety clothing.
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.
