The spray gun conductor
pole may be electrically
charged. Always discon-
nect the system from power
and ground the conductor
pole to the system ground-
ing clip before making con-
tact with conductor pole to
reduce the risk of electric
shock or dust explosion
from electrostatic sparks.
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).

Powder Cups
During operation, air circulates inside the pow-
der cup to produce a fine dust, which is then fed
through the spray gun and onto the workpiece.
To fill and attach the powder cup:
1. DISCONNECT TOOL FROM POWER!
2. Put on eye, lung, and skin protective gear.
3. Make sure the powder cup, gasket, and
mounting cap components (see Figure 11)
are dry and clean of any powder or debris.

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.
