WARNING
•
Avoid high-pressure fluids. Escaping fluid can penetrate the
skin causing serious injury. Relieve pressure before
disconnecting hydraulic lines. Tighten all connections before
applying pressure. Keep hands and body away from pin
holes and nozzles which eject fluids under high pressure.
•
If any fluid is injected into the skin, it must be surgically
removed within a few hours by a doctor familiar with this
type of injury or gangrene may result.

Keep hydraulic coupler tips and connectors clean. Allowing dust,
dirt, water, or foreign material to enter the system is the major
cause of hydraulic system damage. Do
NOT
attempt to service
hydraulic systems in the field. Precision fits require a perfectly
clean connection during overhaul.
