• Do not operate equipment with protective guards or covers removed.
• Pressurized equipment can start without warning. Before checking, moving, or servicing

equipment, follow the Pressure Relief Procedure and disconnect all power sources.

TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin,

inhaled, or swallowed.
• Read MSDSs to know the specific hazards of the fluids you are using.
