5.5 Hydraulics
Understand the safety precautions when working around hydraulic systems, and use hydraulic schematics to troubleshoot
and diagnose performance issues.
5.5.1 Hydraulic Hoses and Lines
Figure 5.3: Hydraulic Pressure Hazard
Check hydraulic hoses and lines daily for signs of leaks.
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.
Figure 5.4: Safety Equipment
IMPORTANT:
Keep hydraulic coupler tips and connectors clean. Dust, dirt,
water, and foreign material are the major causes of hydraulic
system damage.
DO NOT attempt to service hydraulic system in
the field. Precision fits require WHITE ROOM CARE during
overhaul.
