Warnings And Cautions - Section 22 OM2200 Page 22-4 This danger plate is attached to all four suspensions. The plate contains instructions for releasing internal pres- sure before disconnecting any hardware. Serious injury can occur if these directions are not fol- lowed. A plate on the side of the hydraulic tank furnishes instruc- tions for filling the hydraulic tank. Keep the system open to the atmosphere only as long as absolutely necessary to lessen chances of system con- tamination. Service the tank with clean Type C-4 hydraulic oil. All oil being put into the hydraulic tank should be fil- tered 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 sys- tem, 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 person's body by penetrating the skin. Seri- ous injury and possibly death may result if proper medical treatment by a physician familiar with this injury is not received immediately. ht h ht
