To avoid all risks of accident or injury, it is essential to wear:
-Sturdy, non-flammable clothing that is suitably close-fitting
-Strong, non-slip gloves
-Safety shoes
-Protective eyewear
-Safety helmet
-All other equipment necessary on the site or when using the machine
In the case of use of ear defenders, the safety instructions in force on the site must be complied with at all times.
Make sure that the machine vibrations do not lead to a loss of sensitivity in the hands. Adapt the working periods to the level of vibration caused by
the machine, which is shown within the framework of normal use.
Do not work with the machine if you are not sure that you can control it correctly. Do not start working with the machine until you are sure that you
can do so in full safety, for yourself (good conditions of visibility and lighting) and for other people (work calmly and carefully). Take care to ensure
you have a firm, stable footing; all unstable working positions must be prohibited.
The user must be in a physical and mental condition enabling work to be carried out without danger.
The work area must be free of all obstacles. The work area (and the surrounding areas) must be free of all flammable substances.
If anything does not seem clear to you, whether it concerns the machine or the work to be carried out, ask a qualified person for information. Do not
base your work on assumptions.
For underground use (tunnel or gallery), or in a closed area, make sure there is sufficient ventilation or extraction to avoid the risks generated by
inhaling exhaust gases or by their build-up.
This equipment must not be used in an explosive atmosphere.
Avoid working positions in which exhaust gases could come into contact with parts of the body, whether protected or not.
In a general way, take all necessary precautions to prevent flammable products from coming into contact with fire hazards.
The operator must ensure that no one else is within the working area. In particular, it is necessary to make sure that in the direction in which the
machine is travelling, no one can be hit. If someone is nonetheless in the path of the machine, the operator must stop and warn the person of his
passage.
When the machine is installed on the track, it must be handled only by the number of operators strictly necessary for its normal use.
As the overall size of the machines does not enable extinguishers to be carried on them, we strongly recommend placing extinguishers of an
appropriate type to deal with the fire hazards close to the machine.
The user must comply with all the regulatory environmental instructions applicable to the machine in use.

1.3 SECT_Gb_00005_110202 1.3

- ANY HANDLING WORK
- ANY WORK TO CHANGE TOOLS OR SOCKETS
- ANY WORK INVOLVING FUEL OR OIL ( FILLING , TOPPING UP , CHECKING LEVELS , ETC .)
- ANY REPAIR , MAINTENANCE OR CLEANING WORK

1.3 SECT_Gb_00006_110202 1.3
•Using and handling fuel and oil
It is essential to stop the engine and set the control to the stop position before carrying out any work involving fuel (filling up, checking
the level, draining, etc.).
Always keep suitable extinguishers ready for use in all areas where fuel is handled (storage, filling up, etc.).
Always store fuel and oil in separate cans specially designed for the purpose and bearing the labels required by regulations. They must be stored in a
safe place, well away from all types of fire hazard.
Each time a machine is started up, and while it is running, make sure that there are no fuel leaks from any part of the machine. If a leak is suspected,
stop the engine immediately and do not restart the machine until the leak has been repaired.
Never carry out any work on a fuel tank or handle fuel to fill a tank, or for any other reason, in an area where there could be a fire hazard (such as a
burning cigarette, a blowtorch, sparks, etc.) or substances that are incandescent or at a high temperature (such as welding spatters, slag, clinker, etc.).
All such work must always be carried out outdoors or in a well-ventilated area.
Always turn all mobile phones off while filling a tank with fuel or handling fuel.
Carefully tighten the fuel filler cap each time, and check that no fuel leaks from it.
Always remove a filler cap slowly, to enable any internal pressure to be released without spraying any fuel out. Take special care if the surrounding
temperature is high.
When putting fuel in a machine that has heated up, never fill the tank completely. Do not put in more than three-quarters of the tank capacity.
If fuel starts to boil in the tank when putting fuel in a machine that has heated up, screw the cap on again immediately and leave the machine to cool
down.
Make sure the fuel used is suitable for the type of engine on the machine. See the user manual for the engine.
Do not inhale fuel vapour.
If it is necessary to drain the fuel tank, pour the fuel into a container designed for the purpose and bearing the labels required by regulations. Always
close them tightly, even if they only contain a small quantity. Never use a glass container.
Never use fuel for cleaning work. Use only non-flammable, non-toxic products that are harmless for the user, the equipment and environment.
If fuel has been spilt near the filling area for any reason, clean it up immediately. Clean straightaway any spillage of fuel on the skin. Make sure no
fuel has been spilt on your clothes; otherwise, change clothes immediately. Remove all rags or other materials used to wipe fuel, and store them in a
safe place well away from all sources of heat or combustion. Move the machine well clear of any spilt fuel before starting it up (at least 6 metres
away), and do not move any closer to the area while the engine is running.
I N CERTAIN CASES HANDLING OIL CAN GIVE RISE TO THE SAME TYPE OF RISKS AS HANDLING FUEL . I T IS THEN ESSENTIAL TO TAKE THE
SAME PRECAUTIONS WITH OIL AS THOSE SET OUT ABOVE FOR FUEL .

1.3 SECT_Gb_00007_120724 1.3
•Tools to be used on the machine
Use only the types of tools intended for normal use of the machine.
Measure the speed of all rotating tools at regular intervals.
Never use tools at speeds greater than the maximum speed for which they have been designed and approved.
Never use damaged tools or tools that have reached their maximum level of wear.
•The engine on the machine
Never touch the hot parts of the engine, and especially the exhaust pipe. If it is necessary to work on the engine, wait until it has cooled down.
Check the engine rotation speed at regular intervals, and especially after fitting tools or reassembling the machine. Adjust if necessary.
Never exceed the speed shown in the technical specifications.
After starting with the choke, remember to return the choke to the normal running position.
Never wind the starter rope around your hand, and never release it suddenly.
If the machine does not operate correctly after the engine has been started, stop the engine and inform the head of maintenance.
For petrol engines, use only spark plugs whose tops are as shown in drawing 1 opposite. If the plug is fitted with a
screw top, make sure the top is fully tightened. After fitting the spark plug, make sure that the plug cap is in good
condition and that it stays firmly on the plug. Carefully check the fastening system to make sure that no sparks can
be formed.
•Using trolleys (If applicable)
A machine designed to work on a trolley must not be used without the trolley. The trolley is thus an integral part of the machine. The machine and
the trolley must not be used separately.
Trolleys whose use is dedicated to a machine must never be used to transport equipment or personnel, or attached to a vehicle.
Before fitting the machine on its trolley, it must be placed correctly on the track to ensure that it can run freely. If it is on a sloping section of
track, make sure the trolley is kept immobile while the machine is being put on the track or taken off it.
Attention, the trolley takes up the full width of the track and can cause injuries to the legs if it hits someone.

2000N and the lifting rings Ref. ⑤(x4) (if supplied) located at the four corners of the machine (between the chassis and the lifting arms).
The “MC3” frog and switch point grinder can also be put into position by hand using the 4 lifting arms Ref. ⑥located on either side of the machine. The
positioning operation can be carried out by two persons. Nevertheless, if access to the work area proves to be difficult, provide for a sufficient number of
persons so that transport operations can be carried out under satisfactory safety conditions.
Once the machine has been positioned on the rails, it must be immobilized to prevent it
from moving by itself and hitting and injuring anybody. If the machine is fitted with a
roller brake (See Chap.6 “Optional equipment”), check that the brake is on. Otherwise
chock the machine if necessary.
ALL MACHINE-MOVING OPERATIONS ON AND OFF THE RAILS MUST BE CARRIED OUT WITH THE ENGINE SWITCHED OFF
