•Check all pipes, hoses, quick-release couplings and screw joints regularly for leaks and visible
external damage. Repair damage immediately. Pressurized hydraulic fluid leaks may cause serious
injury, and it may cause fire and damage to the environment.
•If parts need to be removed from the hydraulic system, the hydraulic pressure must be released
according to the instructions in this manual before beginning work.
•Expand and install pressurized hydraulic pipes, tubes, and lines in accordance with professional
standards.
•Make sure that no ports have been switched during re-installation work.
•All parts and the length and quality of hoses meet the requirements of Ref 3 “General rules and
safety requirements for systems and their components”.
2.7 Fire
The course of action in the event of an emergency is determined by the rules and regulations applicable
on the worksite. Every company has its own special rules. So, make sure you are up to date on these
rules.
In any case, the following actions are necessary in the event of a fire:
•Keep calm.
•Report the emergency to the employee responsible for in-house emergency services (IHES).
Tell who you are, where you are located and describe the emergency.
(The IHES employee will notify external emergency services.)
•Warn your colleagues.
•Extinguish the fire if it is still in its early stage, using the extinguishing means available onsite.
•If possible, switch off the electrical power supply.
•Leave the scene of the emergency and report to the rendezvous point.
Caution: Never use water to put out an electrical fire or a fluid fire
2.8 Working with hazardous substances
It is thought that special first aid procedures are required in cases of accidents with chemicals.
But in cases of small quantities, standard measures suffice:
1. rinse thoroughly with water
2. wash with soap
3. provide fresh air
4. remove any contaminated clothing
In common the following rules are applicable:
•Contact with skin:
orinse thoroughly with water
oremove any contaminated clothing
owash the relevant body parts with soap.
•Contact with eyes:
orinse thoroughly with water (10 till 15 minutes) using eye wash fountain
oconsult a doctor.
•Ingestion:
orinse the mouth out with water.
oIf necessary, dilute the substance by drinking water.
oIf a corrosive substance has been ingested, do not induce vomiting. This is to prevent the
substance meeting the sensitive oesophagus again.
oIf the victim is unconscious, never attempt to induce vomiting or have the victim drink
anything.
Using a ‘neutralizing solution’ (such as a base for an acid) can make the situation worse.
In addition to this, it is advisable to consult the safety information (TREMCARD book, safety information
sheets and the catalogue) and report everything that is relevant to the accident to a doctor.

When work has to be done in confined spaces:
•Wear personal protection equipment
•ventilate according to the relevant regulations
•Ask a colleague to remain by the entrance to aid in the event of an emergency.
•You are legally required to be familiar with the potential hazards of the product.
The safety information sheets are intended to provide adequate, correct, and up-to-date information
on all substances used on the worksite.
•Relevant safety information sheets are given in E “Hydraulic fluid safety information”.
During maintenance, you may work with substances fitted with GHS symbols.
These GHS symbols are explained in the next below.

CLP is the Regulation on Classification, Labelling and Packaging of substances and mixtures (EC No
1272/2008). This regulation brings European legislation on the classification, labelling and packaging of
chemical substances into accordance with the GHS (Global Harmonised System for classification and
labelling of chemical substances).The GHS is a United Nations system used to identify chemical
substances and inform users of their hazards using standard symbols and phrases on labels, packaging
and Safety Information Sheets (SIS).

2.9 Assembly and disassembly
•Assembly and disassembly of the System has to be performed by properly trained operators
•Only use certified lifting and hoisting equipment.
Check the validity of these certificates and qualifications.
•Only use lifting and hoisting equipment with suitable capacity for the loads in question.
•Before commissioning, any parts that were disassembled for transport must be re-assembled, re-
installed, checked and approved by qualified personnel.
•Make sure that the instructions in this manual have been followed precisely before
commissioning the System.
•Lift loads as described in the user manual (connection points for lifting hooks) and observe the
professional standards.
Hazard: Any components that are blocked or stuck in any way (and any parts connected to these
components) will be under mechanical tension. If you release these parts, they could change position
suddenly and seriously injure you
2.10 Transport, loading and unloading of the System
•Loading and unloading must be performed by properly trained operators
•Only use lifting and hoisting equipment with suitable capacity for the loads in question.
•For lifting parts of the system, observe the directions given in section 5.1.1 “Hoisting Instructions”.
Lifting gear and accessories such as hawsers, shackles, lugs, slings etc. must comply with the
legal requirements imposed in the country of use as well as to Ref 7 “ASME B20.1-2020”.
•Only use suitable containers with adequate load-bearing capacity for transport purposes.
•Secure the load properly using suitable connection points and twist locks (for the containers). When
using twist locks secure them properly and check that the locking mechanism is working correctly.
•Disconnect all electrical and hydraulic connections when the System has to be moved, even if it is
for only a short distance.
•To avoid damage during transport use timbers, rubber pads and plastic for packaging.
•Containers may be used for transport since they provide rigid protection against and avoid weather
influences. Make sure that all parts are secured against sliding around.
2.11 Dealing with hoses
2.11.1 Common directions
•Make sure the maximum permitted pressure is never exceeded:
oDo not change any safety setting.
•Ensure that the accumulators and by-pass hoses are in good condition.
•Do not drive over or stand on the hoses:
oStanding on and driving over the hoses causes’ damage to the hose fabric, which
causes leaks.

Document number: ED.03793.00.001.ENG rev10 Page 20 of 67
oA sudden increase in pressure caused by squeezing the hose causes serious damage
to other components.
•Do not pull on a hose that is connected:
oIf pulling forces are exerted on a hydraulic coupling the hose and coupling interface will
weaken which may result in the hose bursting out of the coupling.
oAlways lift a hose by the hose itself, whilst supporting the coupling.
oStow hoses in such a way that no forces (gravitational force) are exerted on the
coupling.
•While moving the hoses, prevent the couplings being dragged over the ground:
oPrevent excessive wear on the couplings and hoses by transporting them on pallets, if
possible.
oDuring assembly the hose must be supported by necessary use bend guides to prevent
twisting of the hose.
•Protect the hose sleeve in places where chafing etc. cannot be avoided:
oWear spots can be prevented by sliding protective sleeves over areas where wear is
expected or by covering sharp edges.
•Change worn or damaged hoses immediately:
oIf a hose is pressurized continuously by more than 20% above working pressure it must
be replaced.
•Do not use dirty or corroded couplings.
oThey are less reliable
oThey will cause leaks over time.
oThey pollute the hydraulic system
•Disconnecting hydraulic tubing and hoses shall be done with utmost care.
oThe system is designed in such a way that hydraulic pressure drops to zero when the
system is switched off. Nevertheless, pressure can remain due to
▪The presence of load on the system
▪Raise of temperature
oBut the hydraulic connections have been designed in such a way that either
▪they cannot be uncoupled when they’re under pressure, or
▪they can be uncoupled under pressure of only a few bars, but measures have
been taken that no oil can come out
oAlways use the manometers of the System to verify that the pressure is zero.
2.11.2 Main procedure for connecting hoses
1.
Inspect the couplings.
Clean the coupling if dirty.
Replace the coupling if damaged.
2.
Clean the inner and outer side of the couplings before they are mounted; dirt might get in the
system causing damage.
Use degreaser.
3.
Dry the couplings with paper and visually check them for dirt.
Caution: Do not use any brake cleaner or other detergents; they might affect the
couplings.
4.
Screw the screw-coupling together to the end.
While tightening the couplings, the oil passage is opened.
Hazard: Careless handling of hydraulics can cause serious injuries
