Operation

WARNING

Never exceed 20 psi (1.4 bar) static air pressure to the cup. Exceeding the maximum working pressure of the cup or any other system component could cause component rupture, which could result in serious injury and property damage.

WARNING

Pressure Relief Procedure

To reduce the risk of serious injury, including splashing in the eyes or on the skin, always follow this procedure after you stop spraying, when checking or servicing any part of the spray system, before disconnecting the gun, air regulator, or pressure cup and when removing a pressure cup for refilling or cleaning.

1.

Turn off the air supply to the gun.

2.

Trigger the gun into a grounded metal waste container to relieve fluid pressure.

3.

Place the cup on a table and slowly release the clamp (A) to bleed-off any residual pressure in the cup. See Fig. 4. Be sure to push the clamp lever fully to the clamped position before turning on the air supply to the gun again.

Setting the Cup Air Pressure

1.

Pull up the cup regulator adjustment knob lock-ring

(L); this allows the knob (K) to turn. See Fig. 4.

2.

Set the cup pressure at zero by turning the adjustment knob (K) fully counterclockwise.

3.

Slowly turn the adjustment knob (K) clockwise to increase the air pressure to the cup.

4.

Push the adjustment knob lock-ring (L) down to lock the cup pressure setting.

Setting the Gun Air Pressure

Set the gun air pressure regulator for the minimum pressure needed to atomize your fluid. See your gun manual for recommended settings.

Fig. 4

Spraying Tips

The regulator is not self relieving so if the regulated air pressure setting is causing excessive fluid flow, follow these steps.

1.

Pull up the cup regulator adjustment knob lock-ring

(L). See Fig. 4.

2.

Turn the adjustment knob (K) counterclockwise.

3.

Trigger the gun into a grounded metal waste container until cup pressure is lowered.

4.

Turn the adjustment knob (K) clockwise until you obtain the desired pressure setting.

5.

Push down the adjustment knob lock-ring (L).

CAUTION

Do not restrict the fluid flow by continuously spraying with the gun’s fluid adjustment knob

(M) turned in (clockwise) as this will cause excessive abrasive wear on the fluid needle and trigger/air valve shaft.

To restrict the fluid flow, lower the cup pressure or use a smaller size needle/nozzle set and air cap combination.

If the cup pressure must be below 1.0 psi (0.07 bar) to achieve the desired fluid flow, a smaller needle/nozzle size is recommended.

Operation

Optional Gun Air Regulator 235–119

NOTE: See Accessories on page 11 for air regulator replacement parts.

1.

Pull up the gun regulator adjustment knob lock-ring

(L); this allows the knob to turn. See Fig. 5.

2.

Set the gun air pressure at zero by turning the regulator adjustment knob (K) fully counterclockwise.

3.

Turn on the air supply to the gun.

4.

Turn the regulator adjustment knob (K) clockwise to increase the air pressure to the gun.

WARNING

Never exceed 100 psi (7 bar) Maximum Working

Air Pressure to the gun. Exceeding the maximum working pressure of the gun or any other system component could cause component rupture, which could result in serious injury and property damage.

5.

Push the adjustment knob lock-ring (L) down to hold the pressure setting.

Maintenance

Disconnect the Gun and Air Regulator from the Cup

1.

Follow the Pressure Relief Procedure Warning on page 4.

2.

To disengage the tube grip, push down on the outer ring of the lid elbow fitting (N), then pull the tubing (3) out of the fitting. See Fig. 6.

3.

Holding a wrench on the gun fluid inlet fitting, disconnect the pressure cup swivel nut fitting (E).

4.

Disconnect the gun air inlet fitting from the regulator.

5.

If any fluid is in the lid elbow fitting (N), flush it with solvent but do not soak it in solvent for an extended period.

6.

If fluid is in the tubing (3) or check valve (13), replace them. See the parts list for your cup assembly to order parts.

E

5.

Clean the gun as instructed in the gun manual.

CAUTION

Do not clean the air regulators in a gun washer as it will damage the regulator diaphragm. Do not use any cleaning method that allows solvent to enter the regulator internally.

Remove the Cup Lid

1.

Push the clamp lever (A) fully to the unclamped position, against the yoke (B). See Fig. 6.

2.

Twist the cup lid (101) counterclockwise to disengage the yoke hook from the cup extended pins

(C).

3.

Remove the cup lid (101).

4.

Clean the cup lid (101) and cup (103).
