FIRE OR EXPLOSION HAZARD

Static

electricity is created by the flow of fluid through the pump
and hose. If every part of the spray equipment is not properly
grounded, sparking may occur, and the system may become
hazardous. Sparking may also occur when plugging in or un­plugging a power supply cord or using a gasoline engine.
Sparks can ignite fumes from solvents and the fluid being
sprayed, dust particles and other flammable substances,
whether you are spraying indoors or outdoors, and can cause
a fire or explosion and serious bodily injury and property
damage.

If you experience any static sparking or even a slight shock

using this equipment, STOP SPRA
Check the entire system for proper grounding. Do not use the

peuvent également se produire à l’occasion du branchement ou
du débranchement du cordón d’alimentation. Les étincelles sont
suffisantes pour allumer les vapeurs de solvants et le fluide
