Warnings

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.

WARNING

ELECTRIC SHOCK HAZARD

Improper grounding, setup, or usage of the system can cause electric shock.

•Turn off and disconnect power cord before servicing equipment.

•Use only grounded electrical outlets.

•Use only 3-wire extension cords.

•Ensure ground prongs are intact on sprayer and extension cords.

•Do not expose to rain. Store indoors.

SKIN INJECTION HAZARD

High-pressure fluid from dispense valve, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

•Do not point dispense valve at anyone or at any part of the body.

•Do not put your hand over the end of the dispense nozzle.

•Do not stop or deflect leaks with your hand, body, glove, or rag.

•Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.

•Read MSDS’s to know the specific hazards of the fluids you are using.

•Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

•Always wear impervious gloves when spraying or cleaning equipment.

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:

•Use and clean equipment only in well ventilated area.

•Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

•Keep work area free of debris, including solvent, rags and gasoline.

•Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

•Ground equipment, personnel, object being sprayed, and conductive objects in work area. See Grounding instructions.

•Use only Graco grounded hoses.

•Check gun resistance daily.

•If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.

•Do not flush with gun electrostatics on. Do not turn on electrostatics until all solvent is removed from system.

•Keep a working fire extinguisher in the work area.

Machine Calibration

Before the machine will accurately dispense, it must be calibrated.

Be careful not to pinch fingers when manually moving the machine drive block.

Piston Position Calibration (C1)

This step should be executed the 1st time the machine is setup, and may not need to be re-executed unless the position sensor, an electronic component or a piston has been replaced.

From the Run Screen press then press . The following screen will be displayed.

Priming and Calibration

10.The machine pistons should extend slowly until they encounter the cylinder entrance and a number between 2000 to 2400 should appear for ‘H’.

11.If the pistons do not move, manually move the piston by pulling on the machine drive block, until mechanical resistance is encountered at the cylinder entrance.

12.Press to accept the number or to keep the current number.

13.Adjust the Air Pressure Regulator back to a reasonable value for proper machine operation.

14.Press twice to return to the Run screen.

Phasing (C2)

To enable the machine to dispense the correct ratio of material from the A and B tanks and to mix properly, both materials will need to enter the static mixer at the same time. Phasing shots will need to be executed to visually verify that the 2 materials are exiting the dispense valve at the same time.

Remove any static mixer attached to the dispense valve, and replace it with a ratio check nozzle. Place a waste container under the valve to capture any dispensed material.

From the Run screen, press , then press , and then press once. The following will screen will be displayed.

1.Select the location where the piston will reverse (from the extend to retract motion) by pressing or keys. Pressing will decrease the phasing shot. Pressing will increase the phasing shot. A “+” value indicates that the piston will reverse beyond the cylinder entrance. A “-“ value indicates the piston will reverse prior to reaching the cylinder entrance.

2.Press (green) or the footswitch.

3.During the shot execution, visually monitor the 2 materials exiting the ratio check nozzle. If the timing of the 2 materials exiting the nozzle cannot be properly observed, press or accordingly, then repeat step 2.

4.If the A side material exits the ratio nozzle before the B side material (“”), turn the B piston Phase Adjustment Screw/ Locking nut and shaft counterclockwise to move the B piston forward, as indicated on the ICON. Slight adjustments in the piston shaft will be significant. Adjustments of a quarter turn are typical.

5.If the B side material exits the ratio nozzle before the A side material (“”), turn the A piston Phase Adjustment Screw/ Locking nut and shaft counterclockwise to move the A piston forward, as indicated on the ICON.

6.Repeat step 2 until both materials exit the ratio check nozzle at the same time (“”).

7.Press twice to return to the Run screen.

Open Dispense Valve (ODV) Setting (C3)

The next step in the calibration process is to determine the proper position to open the Dispense Valve (DV) during the shot.

Advancing or increasing the opening position (in millimeters) will build more pressure in the material hoses prior to the dispense valve opening. If the Dispense Valve opens too late in the shot, a surge of material can occur or the piston could stall. If the Dispense Valve opens to early in the shot, material “drooling” at the beginning of the dispense cycle could occur.

From the Run screen, press , then press , and then press 2 times. The following screen will be displayed.

3.Press to accept the value or to retain the previous value. The default value from the factory is – 1.0 mm.

4.Press twice to return to the Run screen.

Machine Calibration Shots (C4)

Read all manufacturer’s warning and material MSDS to know the specific hazards of the material used.

Calibration shots are necessary to program the machine to properly dispense the correct amount of

material. Several short CAL shots (“”) and several long CAL shots (“”) are required.

Remove the ratio check nozzle, install the static mixer intended to be used, and adjust the air pressure to the level intended for use during normal operation.

The air pressure must be set to operating conditions for this step. Significant changes in air pressure could adversely affect shot accuracy.

4.Repeat the previous 2 steps until the static mixer is filled with material. Verify the material dispensed from the mixer is mixed properly.

5.Place a container on a scale and tare (zero) it.

6.Place the tared container below the static mixer, and press (green) or the footswitch.

7.Press to erase existing average weight data.

8.Place the container with the dispensed material on the tared scale.
