The hydraulic system is under pressure, and the
oil may be hot!
• Always allow the machine to cool completely
before performing service.
• Always relieve pressure in the hydraulic
system before performing service.
• Always use appropriate safety equipment and
clothing to protect exposed skin and eyes
from high-pressure oil.
• Tighten all connections to proper
specifications before applying pressure.
• Never use bare hands to check for leaks! Oil
under pressure can penetrate the skin and
can cause gangrene within a few hours if not
properly removed. Use a piece of cardboard
to check for leaks.
Failure to follow appropriate safety precautions
may result in death or serious injury.
