Safety - Section 2 OM2025.2 Page 2-24 Warnings and Cautions This Danger plate is attached to all four sus- pensions. The plate contains instructions for releasing internal pressure before disconnecting any hardware. Serious injury can occur if these directions are not followed. A plate on the side of the hydraulic tank furnishes instructions for filling 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 below the hydraulic tank oil level sight gauge. Check level with body down, engine stopped, and key switch “Off”. Add oil per filling instructions, if oil level is below top of sight glass. A warning plate is attached to the hydraulic tank to inform technicians that high pressure hydraulic oil is present during operation. When it is necessary to open the hydraulic system, be sure engine is stopped and key switch is “Off” to bleed down hydraulic pressure. There is always a chance of residual pressure being present. Open fittings slowly to allow all pressure to bleed off before removing any connections.
Any operating fluid, such as hydraulic oil, escaping under pressure can have sufficient force to enter a per- son’s body by penetrating the skin. Serious injury and possibly death may result if proper medical treatment by a physician familiar with this injury is not received immediately .
