INJECTION HAZARD
The system pressure must be manually relieved to pre-
vent the system from starting or spraying accidentally. 
Fluid under high pressure can be injected through the 
skin and cause serious injury. To reduce the risk of an 
injury from injection, splashing fluid, or moving parts, 
follow the Pressure Relief Procedure whenever you:

•

are instructed to relieve the pressure

•

stop spraying

•

check or service any of the system equipment

•

install or clean the spray tip

FIRE AND EXPLOSION HAZARD
When Flushing system, always connect grounding 
cord.
