REMOVAL
WARNING
Do not allow used hydraulic fluid or cleaning solvent to come in contact with unpro-
tected skin or eyes. Prolonged skin contact can cause illness or injury. Eye contact can
cause serious injury. Always wear chemical protective gloves and goggles when han-
dling used hydraulic fluid and cleaning solvent. Failure to comply can result in illness,
serious injury, or death.
Hydraulic hoses and lines may be under pressure. Relieve pressure by operating the
appropriate control valve if possible. Loosen fittings on hose lines slowly. Allow oil to
run around threads of fitting, releasing pressure before disconnecting fitting. Releasing
pressurized oil suddenly may cause severe personal injury or death.
1.
Don chemical protective gloves and goggles.
2.
Place a suitable drain pan under the hose to be replaced.
3.
Hold the fixed end of the piping, fitting, or hose (1) with one wrench, while placing a second wrench on the swivel fitting (2).
4.
Use the two wrenches to "crack" the swivel fitting (2) loose.
5.
Permit any residual hydraulic pressure and hydraulic fluid to drain into the drain pan.
6.
After the fluid has stopped leaking from the swivel fitting (2), finish unscrewing the swivel fitting from the fixed end of
the piping, fitting, or hose (1).
7.
Repeat steps 1-6 for the other end of the piping, fitting, or hose.
