- the chainsaw further comprises a pair of safety handles, namely an upper handle 88 and a lower handle 89.
- each handle is located either above or below the casing, at a certain distance from the upper or lower surface thereof, and is carried by a rod 91 which extends in a plane parallel to the plane of the disc, projecting above and below the casing and ends with a foot-shaped end 92.
- Each handle 88, 89 extends perpendicularly to its support rod and to the plane of the disc, near the foot of the stem.
- a guard 93 is associated with each handle.
- On a lateral side of the casing is fixed a cover 96 which covers an air filter 97 through which, by an internal electric fan, a flow of engine cooling air is drawn in, which passes through the engine and is discharged to the front disc side.
- the suction opening is on the operator side.

- an LED display is provided on the casing, which gives the operator information on the amount of remaining energy available in the battery, compared to the amount of energy required to make a complete cut, following an analysis made by the machine board which lights the LEDs according to the result.
- An example green LED means that the cut can be started and there is enough energy to finish it. The lighting of a yellow LED, for example, indicates that a last complete cut is still possible.
- the display also has a "filter clogging" LED which indicates to the operator that he has reached a cutting number which requires the replacement of the air filter.
- a very advantageous feature of the chainsaw according to the invention lies in the fact that it makes it possible to cut a rail by turning it over, without the operator having to dismantle the machine from the axis of the vice, as illustrated by FIGS. 3A to 3D.

- the operator started the cutting by actuating the safety handle 88 and the rotation control lever 87 when it grasps the handle 86. If cutting is not possible at one time, the operator takes the disc out of the cutting edge, stops the rotation of the disc by releasing the control lever and reverses the machine without dismantling the vice pin 22, passing it from the position of FIG. 3B, on one side of the rail, to the position according to FIG. 3C on the other side of the rail.
- the operator actuates the other safety handle 89 which is now the upper handle and the control lever 87 which he rotates in the opposite direction with respect to the first phase so that the disc can rotate now in reverse.
- FIG. 12 shows the particular configuration of the components of the device for transmitting the rotary movement from the motor axis to the axis of the disc.
- This transmission is carried out using an endless transmission belt 101, which transmits the rotational movement of a roller 103 integral in rotation with the axis of the motor to a roller 105 integral in rotation with the disc.
- a roller 103 integral in rotation with the axis of the motor
- a roller 105 integral in rotation with the disc.
- this strand is deflected by a roller 108.
- the belt 101 is advantageously an elastic belt, striated lengthwise, which does not require tension adjustment or maintenance.
- the invention provides for the use of a roller 109, which is supported by a lever 1 1 1 pivotally mounted around an axis 113 and capable of being fixed in position by a screw 1 15.
- Figure 14 illustrates the different modes of cutting a rail.
- the image on the left shows the type of cut consisting in cutting the entire rail without having to turn the machine over. To make this type of cut, the machine must be equipped with a new disc.
- the other two images illustrate a two-phase cut when the wear of the disc has reached a certain degree and its diameter has decreased so that a total cut is no longer possible.
- the operator working on a first side, first cuts the entire head and the web of the rail, as well as a part of the shoe, the hatched part remaining uncut.
- the system according to the invention can be used with other machine tools such as a vibrator shown at the top of Figure 1 and denoted 2, a rail drill 3 shown in the middle and the impact wrench 4 shown below.
- a vibrator shown at the top of Figure 1 and denoted 2
- a rail drill 3 shown in the middle
- the impact wrench 4 shown below.
- the battery discharge cable is connected to the connector indicated by the reference 121.
- the vibrator is started and stopped by actuation or release of the handle 123.
- the electric motor is cooled by an air flow generated by an electric fan and which passes through the engine.
- an air filter 125 is provided, the removable cover of which has been removed in the figure.
- the engine, filtration and electrical box assembly is covered by a plastic cover (not shown).
- An LED screen 127 is present to indicate the approximate remaining working time.
- the battery discharge cable is connected to the connector indicated at 131.
- each machine tool is equipped with a specific machine card 77 which is specific to it.
- the machine card of the connected machine establishes a dialogue with the BMS card, via the CAN BUS to allow identification of the machine using an identification code which the machine card sends to the BMS card.
- the BMS card which has the function of controlling the switching card, authorizes the closing of the discharge path passing from the battery, through the switching card, the connector card, the multi-wire cable, the machine card and the engine controller to the engine.
- the specific operation of each machine is managed by the machine card, which has the operating program and therefore sends commands to the engine controller to control it.
- the machine is then ready to be used if the start-up conditions are met, that is to say if the operator has actuated the control members, in the case of the chainsaw the control handle and the lever. safety corresponding to the desired direction of rotation of the cutting disc.
