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.

Use a piece of cardboard or paper to search for leaks.
IMPORTANT:
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.

Hydraulic Cylinders
The hydraulic cylinders do not require routine maintenance or service. Occasionally visually inspect cylinders for signs of
leaks or damage. If repairs are required, remove them and have them serviced by your MacDon Dealer.
