OPERATION (PRESSURIZED HOPPER GUN)
Step 1: Check material nozzle before spraying to ensure there is not an air blockage. Step 2: Check to make
sure air relief valve moves freely when button is pushed. Step 3: Make sure hopper air passageway and
air supply tube are free of debris. Only use genuine Graco air supply tube 17V945.
Step 4: Install material nozzle. Step 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.
Step 6: Fill hopper with prepared texture material. Step 7: Fasten lid. Step 8: Pull up on material flow regulator
knob to unlock. Completely close the air flow valve by turning the knob clockwise; turn the material flow
regulator to the lowest setting counterclockwise. Step 9: Turn air compressor power switch ON.
Step 10: Adjust air flow valve and material flow regulator on hopper gun for desired texture. Push down on
the material flow regulator to lock settings.
water immediately. Step 11: To achieve uniform spray pattern, adjust air flow valve, needle travel and material
flow regulator. If you do not achieve the desired pattern, change nozzles, or adjust material thickness.
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-pressurized:
Inspect and clean gun tip before use. Do not clamp air supply tube to barbs.
NOTICE:
If material gets in needle or gun air passages, flush with
