1.4 Special safety instructions

1.4.1 Possible risks incurred when using an "MTZ" type rail-cutting machine

The main risks to users and other persons in the vicinity, liable to be caused by using 'MTZ" type rail-cutting machines are :
Fires caused by handling fuel
Fires caused by sparks touching inflammable material.
Abrasive discs disintegrating due to use under non-compliant conditions (shocks, poor work conditions, faulty or unsuitable discs, etc.).
Injuries caused by flying sparks (specially protect eyes) or even broken discs being projected.
Severe burns caused by contact between a part of the body and the disc when in rotation.
Inhalation of grinding particles.
The disc jamming and the machine jerking upwards
If the disc jams during the cutting operation, this may make the disc disintegrate and the machine jerk upwards.
If the front of the disc jams (especially in the top quarter), the whole rail-cutting machine may be projected upwards and backwards in
an extremely violent rotating movement towards the operator, which can be lethal
To avoid the disc jamming:
1) Always hold the machine with two hand when it is running, one hand firmly holding the rear handle to keep the machine under control at all times, the
other on the front tubular –shaped handle. Put your thumbs around the other side of the handle to hold it properly.
2) Carry out the cutting operation without stopping (if possible). Only continue a cut that has already been started, on condition that the guiding vice has
not been moved and that the SAME machine is used with the same disc. Be extremely carefully when continuing a cut that has already been started.
3) Take all necessary precautions for avoiding the cut sections of rail coming together and jamming the disc during the cutting operation.
4)
Always cut at full power.
Tilting the machine
When cutting, it is formally FORBIDDEN to tilt the machine over 45°
(See diagram opposite).
Above this angle, the operator is no longer capable of holding the
machine correctly and sufficiently firmly. This may result in the machine
jumping out of the slot being cut and jerking up violently towards the
operator. If this occurs, the rotating disc may hit the operator and cause
serious, even mortal injury.
