■1. Safety precautions Be careful about explosion. • Be sure to use paint pump at less than max. fluid operating pressure. Usage at more than max. fluid operating pressure can cause explosion of pump resulting in great danger. • Never bend hose with a radius of less than 50mm. Never put heavy things on it (in order not to damage the hose).
■2. Check the products • Check to make sure the products are as ordered, and they have not been distorted or damaged during transportation.

5-2. Check operation ・Do not idle pump operation. Idle operation can cause pump failure. 5-3. Check operation of diaphragm pump Job 1 Check that ball valve (for air) is closed Job 2 Check that ball valve (for drain) is closed Job 3 Send supply air (0.15〜0.7MPa) to pump Job 4 Tighten handle set of fluid regulator toward “high”...
■6. Preparation for painting 6−1. Cleaning pump ・When you use the product for the first time after purchasing it, clean the inside of pump with cleaning liquid (3〜4 liters). Usage without cleaning can cause painting failure due to rust preventives inside of pump.
■7.Painting job 7−1.Starting job 7−1−1. Painting conditions Job1 Pour paint into 18 liter container (prepare at your side) and put intake hose set and drain hose set into it. Job2 Open ball valve (for drain). Job3 Open ball valve (for air) and operate pump.

10-3-2 assembly Fit tungsten carbide seat to main body so that tungsten carbide ball fits tapered side of the seat. ・ Do not forget to fit packing. Incorrect assembling can cause paint to leak from seated section, resulting in higher actual pressure than pressure shown in pressure gauge. Pay attention to tightening torque when fitting joint to main body.
