Operating Instructions

 

First Check

  • Check all fittings and connections in the pump system, hose, and gun to ensure that they are tight.
  • Check to ensure that there is a spray tip in the gun and that the tip is the correct size for the coating you are to spray. (There are various tips available, for each type of coating or configuration.)
  • Make Sure the power source is securely grounded and match the motor rating of your sprayer.
  • New spray: Oil is used by the factory for testing and protection. It is necessary to flush the unit before spraying. Clean the pump with warm soapy water, Make sure the hydraulic oil in the pump is clean and sufficient in volume then begin the following procedure:
  1. Remove the spray tip from the gun.
  2. Put the input hose and pressure relief tube into the bucket with some water.
  3. Turn on the motor and push the pressure valve upright. In a few seconds, water will begin to flow up through the tube and flow out from the outlet valve, tighten the outlet valve diesel, then tighten the pressure valve diesel.
  4. When the pressure reaches up to around 207 bar, check if there is any leakage on the outlet hose, if it’s a leak, please check. Don’t stop or deflect leaks with your hand, body, glove or rag.
  5. If it doesn’t leak, open the spray gun and have a test spray. Clean the oil from the pump, it's rinsed with oil during production. Use soapy water, and then use clean water when the sprayer is clean.
  6. Turn off the power, continue to spray until the water stops.
  7. Unlock the trigger lock. Put the pressure valve upright, until there is no soapy water in the pump.

Grounding and Electric Requirements

 

  • This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current.
  • This product is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances. Improper installation of the grounding plug can result in a risk of electric shock.
  • If repair or replacement of the cord or plug is necessary, do not connect the green grounding wire to either flat blade terminal. The wire with insulation having a green outer surface with or without yellow stripes is the grounding wire and must be connected to the grounding pin. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if you are in doubt as to whether the product is properly grounded.
  • Do not modify the plug provided. If the plug will not fit the outlet, have the proper outlet installed by a qualified electrician.

The sprayer cord includes a grounding wire with an appropriate grounding contact.

 

 

Power Requirements:

230~240Vac， 50±1Hz，10A， circuit with a grounding receptacle.

 

Spray gun: ground through connection to a properly grounded fluid hose and pump.

Fluid supply container: follow local code.
Solvent and Oil-based fluids: Use only conductive metal pails placed on a grounded surface such as concrete. Do not place the pail on a nonconductive surface such as paper or cardboard, which interrupts grounding continuity.
Grounding the metal pail: Connect a ground wire to the pail by clamping one end to the pail and another end to ground, such as a water pipe!
To maintain grounding continuity when flushing or relieving pressure: Hold the metal part of the spray gun firmly to the side of a grounded metal pail and then trigger the gun.

 

 

Electrical bonding

 

 

A hose, hose assembly, and spray gun assembly shall be constructed to provide electrical bonding to dissipate static electricity from the tip of the Spray gun through the spray gun assembly and the couplings at the ends of the hose to the pump assembly. The spray gun assembly shall also provide an external means to dissipate static electricity during the cleaning process when spraying into a metal container.

 

Construction

Black hose is constructed of an extruded, seamless thermoplastic inner tube, chemically bonded to multi-layers of high tensile synthetic resistant polyurethane cover. A static drain element of flexible, electrically conductive material is located between the braid layers.

 

Compatible Paints

Water-soluble paints with no risk of combustion, such as:

  • Phenol Aldehyde paint series
  • Alkyd paint series
  • Epoxy Resin paint series
  • Oxidized Rubber paint series
  • Latex paint series, etc.

The paint should be stored in a dark and dry place.

 

Troubleshooting

 

Problem

What To Check

What To Do

Basic Fluid Pressure

Pressure control knob setting. The motor will not run if set at minimum (fully counter-clockwise).

Slowly increase pressure setting to see if the motor starts

Spray tip or fluid filter may be clogged.

Relieve the pressure, then clear clog or clean gun filter

Basic Mechanical

Pump frozen or hardened paint.

Thaw sprayer if water or water-based paint has frozen in the sprayer. Place sprayer in a warm area to thaw. Do not start sprayer until thawed completely. If paint hardened in the sprayer, replace pump packing.

Displacement pump connecting rod pin. Pin must be completely pushed into the connecting rod and retaining spring must be firmly in the groove or pump pin.

Push the pin into place and secure with spring retainer.

Motor. Remove drive housing assembly.

Replace motor if fan won’t turn.

Low Output

Worn spray tip.

This occurs when:

1) The working pressure is lower than 1500psi
2) The tip is obviously worn out / worn wider
3) The sprayer has sprayed more than 500L of paint

Relieve the pressure, replace the tip

Verify pump does not continue to stroke when the gun trigger is released.

Service pump.

Prime valve leaking.

Relieve the pressure, Then repair the prime valve.

Suction tube connections

Tighten any loose connections. Check o-ring on suction tube.

Electric supply with a voltmeter.

The meter must read 230-240 Vac or 110V. Low voltages reduce sprayer performance.

Reset building circuit breaker; replace building fuse. Repair electrical outlet or try another outlet.

Extension cord size and length.

Replace with a correct, grounded extension cord.

Leads from the motor to the circuit board for damaged or loose wire connectors. Inspect wiring insulation and terminals for signs of overheating.

Be sure male terminal pins are centred and firmly connected to female terminals. Replace any loose terminals or damaged wiring. Securely reconnect terminals.

Worn motor brushes which must be greater than 1/4 in. (6mm).

 

 

Replace brushes.

Motor brushes binding in brush holders.

Clean brush holders. Remove carbon dust by using compressed air to blow out brush dust.

Low stall pressure. Turn pressure control knob fully clockwise.

Replace the pressure control assembly.

Motor armature for shorts by using an armature tester (growler) or perform a spin test.

Replace motor
