Handling
Petrol version: at the operator’s discretion, the petrol engine can be started directly from the remote control, or the machine can be connected to the 220V single-phase mains using an extension cable.
Lithium version: the machine is switched on from the remote control and is ready to go. By pushing two levers on the remote control, the tracks are started and the machine begins to move in the desired direction.
To improve the stability of the machine when driving on heavy surfaces, the tracks can be widened simply by acting on the remote control. In case of excessive inclination of the chassis while driving, the machine stops automatically and signals the anomaly of use on the remote control. The self-propelled chassis has two travel speeds: “Slow” for maneuvering operations and “Fast” for long movements without obstacles.
Stabilization and self-levelling
Once you have reached the place where you intend to operate, stop driving and start the descent of the outriggers, until automatic levelling has taken place. At the end of the process the tracks will be lifted off the ground.
Opening
It begins with the lifting of the main boom up to a minimum height of 2.80 m, proceeding with the opening of the aerial part until the desired laying position is reached.
Ready to pump
Proceed with the connection of the pipes coming from the concrete pump by means of a rubber hose Ø 100 (4″) directly to the collector pipe of the Gerris 800. The pumping of the concrete is started and it can be laid where necessary by moving the distribution boom.
Small movements during pumping
Gerris 800 performs small movements without the need to close the distribution boom.
