Safety - Section 2 OM2017.2 Page 2-22 Warnings and Cautions A DANGER plate and a WARNING plate are attached to the hydraulic brake accumulators mounted on deck at rear of cab. The danger plate provides instructions on how to relieve hydraulic pressure prior to loosening or disconnecting any hydraulic lines or components while accumulators are under pressure. These plates are also located on the cabinet behind cab. The warn- ing plate is also located on the inside of the box cover. An instruction plate is applied to the side of the hydrau- lic tank. This plate furnishes instructions for filling of the hydraulic tank.
Keep the system open to the atmosphere only as long as absolutely necessary to lessen chances of system contamination. Service the tank with clean Type C-4 hydraulic oil. All oil being put into the hydraulic tank should be filtered through 3 micron filters. A CAUTION decal is attached under the hydraulic tank oil level sight gauge. With body down, engine stopped, and oil level below top of sight glass, add oil per filling instructions.
