Safely
!
WARNING
Exposure to chemical products could result in
serious injury. Handle chemical products with
care. Refer to the chemical manufacturer's
Material Safety Data Sheet (MSDS) for information
regarding health hazards, safe handling, and
emergency response procedures.
Routine service often requires the use of various
chemical products, including lubricants and cleaning
solutions. Many of these chemicals are flammable and
can pose health risks if not handled properly.
• Never mix chemicals. Mixing chemicals can produce
toxic or explosive results.
• Follow the manufacture's recommendations for safe
usage and handling of the product.
• Various materials may pose a health hazard if used
incorrectly. A Material Safety Data Sheet (MSDS)
contains important information regarding proper
handling and health hazards, as well as emergency
response procedures. Contact the chemical
manufacturer to obtain an MSDS for the chemical

Service Hydraulic System Safely

!
WARNING
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.
Always dispose of used hydraulic oil properly. (See
"Dispose of Waste Materials Safely" on page 1-10.)
