2.4 Safety inst ructions
2.4.1 During installation and maintenance
Warning
Never work alone when installing heavy components, even when using securelifting equipment such as lockable block and tackle. Most lifting devicesrequire at least two people, one to see to the lifting device and one to ensurethat the components do not get caught and damaged.
Using other hydraulic oil than specified may cause personal injury andequipment damage.
Always wear protective goggles if there is a risk of splinters, grinding sparks
and splashes from acid or other chemicals. Your eyes are extremely sensitiveand an injury to them can result in you losing your sight.
Caution!
Most chemicals intended for the product (engine and gearbox oils, glycol,gasoline and diesel), or chemicals intended for the workshop (degreasing agent,paints and solvents) are harmful to your health. Read the instructions onpackaging carefully! Always follow protective measures (using a protective mask,goggles, gloves etc.). Make sure that other personnel are not unknowinglyexposed to harmful substances in the air that they breathe for example. Ensurethat ventilation is good. Deal with used and excess chemicals as directed.
Plan in advance so that you have enough room for safe installation and (future)dismantling. Plan the compartments so that all service points are accessible.Coming into contact with rotating components, hot surfaces or sharp edgeswhen servicing and inspecting the rudder system must not be possible.
Prior to welding, check that the electric system of the boat is disconnected.
Ensure that the warning or information decals on the product are always visible.Replace decals that are damaged or painted over.
Take care of the hydraulic oil when replacing parts in the hydraulic system. Anyoil spillage, even a small one, will cause environmental damage. Used filter
elements and worn out hydraulic oil should be disposed safely.
If hydraulic oil disappears from the system and there is a risk that this oil ispolluting the seawater, the system must be immediately shut down andinspected.
Do not use the Rolls-Royce Product Name if local rules do not permit this.
Note!
Use spare parts produced by Rolls-Royce Marine, or by a manufacturerapproved or licensed by them. Use of other than approved spare parts will voidthe warranty and may result in system failure or reduced lifetime.

4 HANDLING AND PRESERVATION
4.1 Delivery checkImmediately upon arrival, the equipment packing must be inspected. If there are any complaints,you must inform Rolls-Royce Marine as soon as possible.
Preservation used on all surfaces - not primed nor painted - is Cortec VCI-369. This is a corrosioninhibitor prepared for temporary coating. The preservation needs only to be removed in contactareas. It can easily be removed using soap and water or similar.
4.2 Storage
Preservation of components is prepared for transport and short storage only. Please check the
expiration date of this preservation on labels following the shipment. This is yellow stick-on labelsas shown below:
Storage days are counted as delivery date to first start-up.
During storage, it is important to protect the equipment against corrosion as well as moisture anddust. At the shipyard, store all goods indoors. Temporary built shelters with good ventilation can beused for some heavy components. All openings and pipes are to be sealed off at all times. Fill thepipes with oil to inhibit rust. Preferably use oil specified by Rolls-Royce Marine.
Caution!
