Information
CAUTION
Model 980 non–bleeder style spray guns are for
use with Graco GTS T urbine Systems. Do not use
with previous models of Graco or Croix turbines.
Use will dramatically shorten turbine life.
NOTE: Model 980 HVLP spray guns dif fer from tradi-
tional non–bleeder guns by the constant low velocity
airflow designed to prevent restriction and plugging of
aircap orifices.
Connect Fluid and Air Supply
1. Connect gun air supply hose (A) between turbine
air outlet (B) and gun air inlet (C). DO NOT use
wrench to tighten connections; hand–tighten only .
See Fig. 1.
2. If using spray gun cup (D), connect cup to gun
fluid inlet (E).
3. If using accessory remote pressure pots (F),
connect fluid supply hose (G) between remote
pressure pot fluid outlet (H) and gun fluid inlet (E).
Connect pressure pot air hose (J) between pres -
sure pot air regulator inlet (K) and the cart com -
pressor air outlet (L).
NOTES:

The HVLP Cart/Compressor provides the air supply
for remote pressure pot.

fluid sets. T o install other fluid sets, perform the follow -
ing steps. See Fig. 2.
1. Remove air cap retaining ring (28). Discard pack -
aging (not shown). Remove detente plate and
spring (26).
2.
Remove fluid regulator assembly (18, 19, 20) and
spring (21) from back of gun.
3. Fully insert needle assembly (14) into back of fluid
manifold (6).
4. Perform needle adjustment procedure steps 2 thru
5 of Adjusting Needle on page 16.
5. Perform needle packings adjustment procedure
steps 4 thru 8 of Adjusting Needle Packings on
page 16.
Prepare 980 Cup Gun for Pressure Feed
1. Remove air pressure tube (31) from air stem (34).
See parts drawing on page 20.
2. Hold fluid inlet fitting (7) with wrench and remove
cup assembly (32).
3. Remove air stem (34) from gun body (1).
4. Apply medium strength threadlocker to set
screw (30) and assemble to gun body .
Prepare Fluid
1. Always strain fluid before spraying; this includes
color, reducer , and hardeners.
2. Use slower drying reducer or thinner to compen -
sate for faster drying time from warm turbine air .
Do not over reduce.
Paint Reduction – Automotive Type Finishes
Reduce and catalyze all paint to manufacturer ’ s speci -
fications. Compensate for faster turbine drying time by
using reducer one-step slower than conventional air
spray.
