Page 30: Coupling Hydraulic Hoses To Avant Loader
Coupling hydraulic hoses to Avant loader On Avant loaders the hydraulic hoses are connected using the multi connector system. Keep all fittings as clean as possible; use the protective caps on both the attachment and the loader. Dirt, ice, etc. may make using the fittings significantly more difficult. Never leave the hoses hanging on the ground;... - Page 31 To disconnect the multiconnector system: Before disconnecting put the attachment down on a solid and even surface. Before disconnecting the fittings, lower the attachment to safe position on solid and level surface. Turn the control lever of the auxiliary hydraulics to its neutral position. When uncoupling the attachment, always disconnect the hydraulic couplings before unlocking the quick coupling plate, to prevent hose damage and any oil spills.

Page 35: Material Handling
Material handling Do not over fill the Bucket as this will reduce the performance of the screening process and can damage your Avant compact screening system. There is too much material in your Avant compact screening system if you are unable to see the top shaft when material has been loaded. - Page 36 Material handling The Avant compact screening system’s efficient screening process is created by the star rotors, rotating the pre screened material in the bucket, allowing fines to flow through the star rotors leaving the oversize material in the bucket. Less material in the bucket = more production Once the screening process is completed, the oversize material is tipped out and the process is repeated.
