Operating - GEISMAR STUMEC MTZ 350S Manual

1.4.6 Operating

• The rail-cutting machine must only be used by a single authorised
operator.
• The rail-cutting machine must ALWAYS BE USED WITH ITS OWN
GUIDING VICE. This must be fixed on the rail in the right position for
the cutting operation.
• If works are being carried out on a double-track, pay special attention to
any traffic running on the track still in use. In any case, the rail-cutting
machine must only be used in compliance with railway authority
instructions applying to its place of operation.
• This machine has been designed and built solely for cutting railway
rails. Any other use different from those described in this manual will
be considered "non-compliant" and will release the constructor from
any liability whatsoever, this being totally borne by the user.
"Compliant use" implies observation of all the recommendations
inherent to the use and maintenance of the machine described in this
manual. All instructions recommended and described for preventing any
occupational accidents must also be followed, whilst taking account of
all general regulations in force in terms of safety, occupational medicine
and legislation, at the same time.
• Before starting the machine, check that the disc and belt guards are in
good condition and that they are correctly fixed in place. Never modify
them.
• Install a new guard every time an abrasive disc breaks up or when the
guard appears to be in poor condition.
• Never use ether or any similar product to help start the engine.
• Do not operate the machine using the forced acceleration device. This
should only be used when starting up.
• Never leave a rail-cutting machine by itself when the engine is idling.
Stop the engine as soon as the machine is no longer in use. Before
putting the machine down, wait until the disc has completely stopped
turning.
1.4
• The engine must ALWAYS be stopped before carrying out any repair or
maintenance operation. If the engine has to be run (for setting the
carburettor or checking maximum no-load speed), make sure that the
work area is correctly ventilated.
• Never use a rail-cutting machine with a faulty exhaust system (risk of
fire and damage to hearing).
• Make sure that there is no-one present in the machine's area of action.
As particles may be thrown over long distances, sufficient space must
be left between the axis of the rail-cutting machine and any persons
close-by. If this is not possible, try to direct the spark flow in a direction
where there is no danger (either directly or by rebound). Otherwise,
install a fireproof screen for catching any sparks.
• During cutting, projection of incandescent sparks
creates a risk of fire. If necessary, place a screen in
position for intercepting the flow of sparks before they
can reach any inflammable matter (danger of brush
fires in summer).
• As soon as the engine starts running, it gives off toxic
exhaust gasses. These gasses may be odourless and
invisible. Never use the machine in confined or poorly
ventilated spaces. When working in ditches, dips in
the ground or enclosed areas, always make sure that
there is adequate ventilation. Danger of intoxication.
• Perfect idling speed adjustment is particularly important for preventing
the disc from turning when the accelerator trigger is released (please see
§5.1.4 "Carburettor" if any adjustment is required). NB: Even when the
accelerator trigger has been released, the disc will continue to rotate for
a short moment.
• If compressed air is used for cleaning, protective and a mask or glasses
must be worn. Air pressure must be under 2 bars at the outlet nozzle.
