7.3.3.1 - Oil replacement
Replace oil after each major intervention, and each time an anomaly has been detected.
Take an oil sample each year, check the viscosity, ensure there are no foreign bodies and
change if necessary. Systematically change the oil in the hydraulic circuit every 2 years.
• Only use oils that that match the technical characteristics that correspond to HAULOTTE®
recommendations ( Section B 1 - Lubrication diagram - List of ingredients) or contact
HAULOTTE Services®.
• Do not mix two oils with different characteristics : If necessary, drain and clean the whole system.
• Check the cleanliness of the oil filter cartridge (no metal shavings, rubber, plastic, …) : If necessary,
drain and clean the whole system.
• Respect the following step during filling :
• The machine must be completely stowed (For machines fitted with : Stabilisers raised).
• Fill the tank.
• 1 : Perform a complete cycle (fully extend and retract) of each cylinder.
• 2 : Fill the tank if necessary(Never above of the maximum level).
• Repeat the step ( 1 ) and ( 2 ) for each cylinder on the machine.
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.
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.
