The following instruction will help in smoother operation of the pump.

 

1. Fill the tank with clean water only. If dust or other foreign particles enter through the water into the valves, it might cause pressure dropping.

 

2. Before starting operation, the pressure release valve should be kept open and water should be allowed to drain for few strokes, then close the valves and build the required pressure. This is to remove air, or else constant pressure cannot be developed.

 

3. Maximum length of the stroke can be used while beginning and should be progressively reduced when the pressure developed.

 

4. If the check valve found disturbed and pump fails to develop pressure, the valve seat should be cleaned or lapped if necessary.

 

5. Suitable lubrication oil should be used to lubricate the plunger and ensure smoother operation.

 

6. While keeping the pump idle, apply, lubricant oil and insert the piston fully in the cylinder so that water content will not remain inside the pump and shall be free of being rusty.
