Prime Empty Sprayer

Prime Empty Sprayer

Prime A and B Fluids

Wear gloves when using flush solvents and/or if the fluid temperature exceeds 110°F (43°C).

NOTE: The equipment is tested with mineral oil at the factory. If necessary, flush out the oil with a compatible solvent before spraying. See Empty and Flush Entire System (new sprayer or end of job), page 27.

Do not install the gun spray tip yet. To avoid splash- ing, use the lowest pressure possible to prime.

1.Condition the materials prior to adding to the hop- pers (J). Ensure that the resin materials are thor- oughly mixed, homogenous, and pourable prior to adding to the hopper. Stir the hardeners back into suspension prior to adding material to hopper.

2.Fill the A and B reservoirs with proper materials. Fill the A side (blue) with major volume of material; fill the B side (green) with minor volume of material (unless 1:1 mix ratio).
