2

Turn off turbine sprayer.

3

Remote Pressure Pot:

 Turn 

out 

pressure relief 

knob (113) one turn. Wait until pressure is 
completely relieved before removing cover. Close 
knob.

Spray Gun Cup:
Note: 

Elevate spray gun and pull trigger. This will 

allow fluid in hose to drain back into remote 
pressure pot.

a. Unlatch cup cover; loosen or remove cup from 
cover to relieve pressure.

b. Clean spray gun and cup as instructed in

Accessory Remote Pressure Pot

1

Follow Pressure Relief Procedure, page 9.

2

Remove pressure pot cover and fill. Secure cover.

Note:

 Lightly coat cover threads with petroleum jelly.

Note: 

Always spray with the least amount of pot pres-

sure required to provide the desired spray pattern and 
rate of application, typically 10 psi. Spraying at pot pres-
sures higher than necessary wastes paint and can result 
in an orange peel finish.

Fill Cup or Remote Pressure Pot

Spray Gun Cup

Fill cup 3/4 full to keep air pressure tube clean. Install 
cover. Latch the under-cup cover (H) to secure it to cup. 
Fig. 4. The overcup (J) has threads to secure it in place 
on the cup.

WARNING

The accessory remote pressure pot remains 
pressurized until pressure is manually relieved. 
To reduce the risk of serious injury from pressur-
ized fluid or accidental spray from gun, always 

relieve pressure

 in the pressure pot before loos-

ening or removing the cover. Also, 

relieve pres-

sure

 if the fluid nozzle clogs; and before 

cleaning, checking or servicing equipment.

CAUTION

If the 2-quart remote pressure pot is accidentally 
tipped over or held at too great of an angle, fluid may 
leak into air regulator and cause damage. Take pre-
cautions to avoid this. If fluid does get into regulator, 
clean immediately.

CAUTION

Only hand-tighten pressure pot cover. Excessive tight-
ening may damage cover gasket.

WARNING

The spray gun cup is pressurized by the gun’s air 
supply. To reduce the risk of serious injury from 
pressurized fluid or accidental spray from gun, 
always turn off the air supply to the gun before 
removing the spray gun cup.
