Adjusting the air regulators
WARNING
To reduce the risk of overpressurizing the tank,
which could result in component rupture and cause
serious injury:
Never exceed 50 psi (350 kPa, 3.5 bar) MAXIMUM
AIR INPUT PRESSURE to the tank.
Never operate the pressure tank without the tee
(9e) in place. The tee acts as a restrictor to limit
the air pressure to the tank.
Turn the air regulator knob(s) counterclockwise all the
way to off. Turn on the master air supply. Adjust the air
regulators to the required pressure. Always use the low-
est pressure necessary to obtain the desired results.
Lower pressures help reduce spray tip wear.
Vertical and horizontal reach
Do not operate the spray gun more than 10 ft (3.1 m)
above the paint tank. Longer lengths of air and paint hose
may be used between the pressure tank and the spray
gun for greater horizontal working range.
Cleaning and maintenance
Follow the Pressure Relief Procedure Warning. Loos-
en the wing nuts and remove the cover (H). Loosen the
retaining ring of the spray gun air cap about three turns.
Hold a rag over the air cap and trigger the gun to force the
paint back through the hose and into the tank. Empty the
tank.
Operation
Pour a compatible solvent into the tank.
Be sure the solvent you use is compatible with the
fluid being sprayed and the hose material.
Replace the cover and tighten the wing nuts evenly and
securely. Remove the spray gun air cap. Turn on the air
supply. Trigger the spray gun into a waste container until
clean solvent comes from the gun. Empty the solvent and
wipe the inside of the tank and the equipment with a sol-
vent-dampened rag.
Remove the riser tube (E) and clean it thoroughly.
Keep the safety relief valve (1b) clean and in working or-
der. The relief valve is preset and locked and will release
air pressure automatically if it exceeds 50 psi (3.5 bar).
Check the release pressure of the safety relief
valve (1b) weekly. If this setting has changed or it
paint comes in contact with the valve, remove and
clean the valve thoroughly. If the valve still doesn't
work properly, replace it with a new one.
DO NOT TRY TO RESET THE VALVE.
Keep the bottom of the wing nuts well greased so they will
screw down freely.
See the separate instruction manuals for the care and
maintenance of the spray gun and air regulators.
