5.Connect the tool to the air supply (but NOT to power) and use the spray gun trigger to send air through the gun to make sure any residual powder from the last operation is cleared away.
6.Remove the powder cup from the spray gun and fill it with up to 2" of powder.
Note: Leaving space in the powder cup allows the powder to circulate into a fine dust when the air is applied.
7.Make sure the gasket is in place inside the mounting cap, then turn the gun upside down and thread the powder cup onto the mounting cap (see Figure 12).

Curing
Curing the powder coating is a process that melts the powder into an even finish that adheres to the workpiece. This is done with a dedicated electric oven that is not used for any other purpose.
Follow the powder coat manufacturer's recom- mendations for curing temperature and length of time to produce good results.
The powder coating will NOT adhere to the workpiece unless it is properly cured in a dedicated electric oven. Follow all recom- mendations made by the power coat manu- facturer for properly curing their product.
