Servicing hydraulic equipment
Most hydraulic failures are due to oil contamination.
It is very important to filter the oil when filling the oil reservoir.
Only qualified personnel should dismantle hydraulic equipment following the rules below:

Immobilize the vessel to prevent uncontrolled movements.

Before doing any maintenance, make sure that the reverse duct is in the fully down position.

Cleanliness is of the utmost importance. Dirt or foreign material in the hydraulic system can cause
serious damage or incorrect operation. Always work in a clean environment.

Before disconnecting hoses, thoroughly clean the outside of the fittings to prevent dirt from entering the
ports.

When removing hoses, always make sure to plug the ports and pipes.

Label hoses and connectors for ease of reassembly.

Use plenty of oil absorbent cloth to prevent contaminating surrounding areas.

Renew all seals removed during dismantling.

Strictly adhere to all recommendations for oil grade, oil and filter inspections and changes shown in this
manual.

In severe conditions where the oil is likely to become contaminated, replace the oil and oil filter at more
frequent intervals.

Always check the oil level in the reservoir whenever removing oil from the hydraulic system.

Unless otherwise specified, lubricate stainless steel hydraulic fittings with hydraulic oil or general
purpose grease (for example, Accrolube®).

Carry out the maintenance with the valves at room temperature.

Before opening the hydraulic circuit, make sure the system is off and de-pressurised.

Before disconnecting any electrical wiring, make sure that the power is off.

Refill the system with approved oil.

Dispose of waste oil in accordance with current regulations.
Change the oil immediately if contaminated in any way.
Dismantle and clean all components thoroughly and flush the hydraulic lines with Kerosene, Varsol
or Diesel oil.
Deck mounted controls
Visually inspect deck mounted module seals and protective housings on a regular basis to make sure they are
in still good condition.
