1.1 GENERAL RULES AND CONVENTIONS This ENCLOSURE 02 is an integral part of the product, therfore it MUST be preserved with care for any further reference together with the reference manual of the equipment.




1.2 DESCRIPTION The component described in this “ENCLOSURE 02” is a valve that regulates the oil flow of “PUMP 2” (See hydraulic schemes in the chapter “1” of "TOAL-2" general instructions and maintenance manual). It is mounted on MARTE 24, MARTE BIPOWER, MERCURIO 24, MERCURIO BIPOWER, GIOVE 24, GIOVE BIPOWER and TOAL 2. The flow regulation valves regulates the oil flow to the lever remote hydraulic valves for head, set of disks sliding out and set of disks back in. In case of irregular vibrations and oscillations noticed when the inter-trunk is working, especially during the set of disks back in movement (too high oil flow), or slow movements during the set of disks sliding out or head (poor oil flow), the oil flow to the remote hydraulic valves can be adjusted by acting on the flow regulating valve. See description in "Section 6".
