Hydraulic Hoses and Lines
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.

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
