Page 12: Starting And Stopping The Engine
Fig. a 4.4) Starting and stopping the engine Always start the machine at a safe distance from the re- fuelling area. Start the engine only when the abrasive cutting disc is mounted. Fig. b Before starting, check that the abrasive cutting disc can rotate freely. - Page 13 Fig. f Wait until the disc has completely stopped before mounting the machine on the support arm. – Restart the engine (Fig. f). The engine can be turned off : • On the machine: release the accelerator and turn the main switch to the right into the STOP position.
- Page 14 The AA-RDS automatic support arm allows the machine to cut rail without operator contact as it picks up the motion from the rail saw and automatically simulates the movement of the ope- rator during cutting; the rail saw is guided to obtain a perfectly perpendicular and straight cut. Furthermore,this arm safely supports the rail saw in a comfortable position to facilitate fi...

- Page 18 - Rotate the blue lever (18) in order to lock it in the external position, to facilitate this operation it is advisable to keep the arm slightly raised from the base by gripping it in position (A) with one hand. - At the same time unlock red lever (17).
- Page 19 IMPORTANT (Ref. to fi gure below): Make sure that at the end of rotation, lever (L) is resting on the bushes (A) so that the spring rod is positioned downwards; otherwise, it will not be possible to support the rail saw and perform the cut. 6.3.1) Rotating the interface group The overturning of the arm from one side of the rail to the other also requires the rotation of the interface group...

- Page 21 WARNING: WARNING: - Always consult your employer’s rules and procedures to cut rails in presence of electrical traction return current. - Never leave the rail saw unattended while cutting. - Make sure that everyone keeps a safe distance away from the cutting zone. - During the cutting operation move to a safe distance and always keep the auxiliary switching device close to hand if any problems occur during cutting.
- Page 22 – With the disc in contact with the rail, completely release the arm. – The rail saw will automatically perform regular alternate movements simulating the cutting action of an operator. During operation always keep a safe distance and always monitor the cutting process in order to readily intervene in case of problems.
- Page 23 If the rail saw stops at the rail head shortly after starting the cut, it means that the cutting force is too high: rotate the adjustment ring a couple of turns towards higher values in order to put more load on the contrast spring. If the rail saw stops at the intersection between the rail web/foot towards the end of the cut, it means that the cutting force is insuffi...
