Operation (Pressurized Hopper Gun)
For the best spraying experience, always
follow the Setup and Operation procedures.
This ensures that the material and spray
system are ready to spray resulting in a
successful project.
Texture Spraying
1. Check material nozzle before spraying
to ensure there is not an air blockage.
2. Check to make sure air relief valve moves
freely when button is pushed. Take apart
and clean if necessary. Grease o-rings
and reassemble.
3. Make sure hopper air passageway and
air supply tube are free of debris.
Only use
genuine Graco air supply tube 17V945.
4. Install material nozzle.
5. If using WideTex adapter, install disc (2)
on front of adapter (3) with retaining ring
(1). Install a standard nozzle (4) on front
of gun with the assembly. Pulling trigger
when installing nozzle makes assembly
easier. If desired finish is not achieved,
try a different size standard nozzle. See
Recommended Nozzle & Disc
Selection Charts, page 19.
RUPTURE HAZARD
Over-pressurization can result in hopper
rupture and injury. The air supply tube is
designed to disconnect if hopper is
over-pressurized.
To avoid over-pressurization:
• Inspect and clean gun tip before use.
• Do not clamp air supply tube to barbs.
