PRESSURIZED EQUIPMENT HAZARD
Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause
serious injury.
• Relieve the pressure when you stop spraying/dispensing and before cleaning, checking, or servicing
equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
PRESSURIZED ALUMINUM PARTS HAZARD
