7.3.3.2 - Replacing damaged of hoses
Replace hoses in the following circumstances :
• Tears in the outer casing.
• Cracks in the outer casing.
• Apparent shielding.
• Visible leak in the hose.
• Damage to the outer casing caused by chemical reaction from a foreign source.
N.B.
-:-Slowly undo the hose end fitting to allow the residual hydraulic pressure to dissipate.
Tightening torque table
To protect personal safety, observe the following conditions when disassembling or reassembling
components :
• Stow and park the machine on level cleared ground(The machine should not be tilted. The boom at
horizontal position).
• Stow the machine completely.
• Place barriers around the perimeter of the work area (risk area = maximum height of the machine).
• Locate the faulty hose/s and their end connection points, to ensure proper machine operation after
intervention.
• Identify and memorise the hose path of the hose to be replaced.
Use an oil collection pan to avoid polluting the environment.
• After hose removal, plug the the hose ends and components the ports from which the hose was removed,
to avoid polluting the hydraulic system.
• Check the cleanliness of the hoses and hydraulic components (no metal cutting, rubber, plastic, …).
• If necessary, drain and clean the whole system (tank included).
• Tighten to the torque indicated when reassembling.

has/have been replaced, a few times.
• Check the oil level in the hydraulic oil tank.
• Check the pressure.
