This equipment is used with heated
fluid which can cause equipment
surfaces to become very hot. To avoid
severe burns:
• Do not touch hot fluid or equipment.
• Do not turn on hose heat without
fluid in hoses.
• Allow equipment to cool completely
before touching it.
• Wear gloves if fluid temperature
exceeds 110°F (43°C).
Thermal expansion can cause
overpressurization, resulting in
equipment rupture and serious injury,
including fluid injection. Do not
pressurize system when preheating
hose.
