C. MachinePreparation Procedures 1. Movethe machine to a firm, level testing area. 2. Operatethe attachmentcontrols until the machineis in the HydraulicOil Checkposition. SeeFigure 2.1. 3. Allowthe hydraulicoil to reacha temperature of 45°Cto 55°C(113°Fto 131°F). 4. Turn engine"OFF". 5. Releasehydraulictank pressureby removing capfrom pressurerelief valve anddepressing relief valvestem.SeeFigure2.2.
¯ BE EXTREMELY CAUTIOUSWHILE RELEASING HYDRAULICTANK PRESSUREOR REMOVING LINES ANDFITTINGS, VAPORS ANDOIL MAYBE EXTREMELY HOT. ¯ WEARAPPROVED SAFETYCLOTHES, SHOES, GLOVESAND HARDHAT WHENPERFORMING ANY MAINTENANCEOR TEST PROCEDURES. 6.
