Setup
Flush Before Using
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid
contaminating your fluid with oil, flush the equipment
with a compatible solvent before using the equipment.
See Flushing and Cleaning, page
16.
Follow the Pressure Relief Procedure, page 14.
Select a Spray Tip and Air Cap
The fluid flow and pattern width depend on the size of
the spray tip, the fluid viscosity, and the fluid pressure.
See Spray Tip Selection Charts, page
32. Contact
your Graco distributor for assistance in selecting an
appropriate spray tip for your application.
