Gun Setup

The floor of the spray area: must be electrically conductive and grounded. Do not cover the floor with cardboard or any non-conductive material which would interrupt grounding continuity

All persons entering the spray area: must wear shoes having conductive soles such as leather, or wear personal grounding straps. Do not wear shoes with non-conductive soles such as rubber or plastic. If gloves are necessary, wear the conductive gloves supplied with the gun. If non-Graco gloves are worn, cut off fingers or palm area of gloves to ensure your hand contacts the grounded gun handle.

Flammable liquids in the spray area: must be kept in approved, grounded containers. Do not use plastic containers. Do not store more than the quantity needed for one shift.
