ASSEMBLY

 

Attach the hose to the pump and tighten with a wrench. 

Attach the hose to the gun and tighten with a wrench. 

 

OPERATION

 

1  New sprayer / before you start 

 

Your sprayer was factory tested in an oil solution which was left in the pump. 

 

Before using oil-base paint, flush with pump conditioner only. Before using 

 

water-base paint flush with pump conditioner, followed by soapy water, then 

 

a clean water flush. 

2  Changing colours 

 

Flush with a compatible solvent such as pump conditioner or water. 

3  Changing from water-base to oil-base paint 

 

Flush with soapy water, and then pump conditioner. 

 

PRESSURE RELIEF PROCEDURE

 

IMPORTANT! To avoid possible serious body injury, always follow this  

procedure whenever the sprayer is shut off, when checking it, when  

installing, changing or cleaning tips and whenever you stop spraying. 

Engage the gun safety latch. 

Turn the unit off and unplug it from the electrical outlet. 

3

  Disengage the gun safety latch and trigger the gun to relieve residual fluid  

 

pressure. Hold metal part of the gun in contact with grounded metal pail. 

4

  Turn the Priming Valve to the open (priming) position to relieve residual  

 

fluid pressure. 

5

  Re-engage gun safety latch and close Priming Valve. 

If the SPRAY TIP OR 

 

HOSE IS CLOGGED, follow Step 1 through 5 above. Expect paint splashing 

 

into the bucket while relieving pressure during Step 4.

FLUSHING

 

WHEN TO FLUSH 

1

 

Cleanup 

(for further instructions see “cleanup” below) 

2

 

Changing from oil-base to water base paint. 

Flush with pump conditioner, 

 

followed by soapy water, then a clean water flush. 

3  Storage.

 Always relieve pressure (See pressure relief procedure above) prior 

 

to storage or when machine is unattended. 

 

Oil-base paint: 

Flush with pump conditioner. Ensure that there is no pressure 

 

in the unit, then close the priming valve. 

 

Water-base paint: 

Flush with water, and then pump conditioner.  

 

For longer term storage fill with pump conditioner.  

 

Always ensure that there is no pressure in the unit, and close the prime/

 

pressure relief valve for storage. 

4  Start-up after storage

. Before using water-base paint, flush with soapy water 

 

and then with clean water. When using oil-base paint, flush out the pump  

 

conditioner with the material to be sprayed. 

HOW TO FLUSH 

1

  Be sure the gun safety latch is engaged and there is no spray tip in the gun. 

2

  Pour enough clean, compatible solvent into a large, empty metal pail to fill  

 

the pump and hoses. 

3

  Place the suction tube into the pail. 

4

  Turn the Priming Valve to the ‘Open’, priming position. 

5

  Point the gun into the metal pail and hold a metal part of the gun  

 

firmly against the pail. 

To reduce the risk of static sparking which can cause 

 

fire or explosion, always hold a metal part of the gun firmly against the 

 

metal pail when flushing. This also reduces splashing. 

Disengage the gun 

 

safety latch  and squeeze the gun trigger. Turn the ON/OFF Toggle Switch to 

 

the "ON"  position and turn Pressure Control Knob clockwise to increase  

 

pressure just enough to start the pump. 

6

  Close the priming valve. This will allow solvent to be flushed through the 

 

pump, hoses and gun. Allow the unit to operate until clean solvent comes 

 

from the gun. 

7

  Release the trigger and engage the gun safety latch. 

8

  Whenever you shut off the sprayer, follow the 

PRESSURE RELIEF  

 

PROCEDURE.
