DSY-6 electric test pump 
 Test pump | electric test pump | pressure controlled test pump | mini electric test pump 
 1, methods of operation 
 (1) Loosen the red pressure adjustment knob, plug the power cord turn on the motor to see whether there is suction machine, and then shut down the pipe will be shown by the connection. 
 (2) open the motor, to be out of the water pipes from the back, the Tighten the relief valve, and then screw down the pressure adjusting knob slowly until the pressure gauge readings on the pressure required to achieve your required date, then tighten locked tight film, shutdown. 
 (3) Check the reading on the gauge at this time whether the readings do not fall down if the container is that the pressure measured performance is good, otherwise a leak inside the container that the place exists. 
 (4) after completion of work should loosen the pressure relief valve and pressure adjustment knob, then remove the various types of pipe in order to make the machine and then open the motor idling about half a minute, drain the remaining water damage inside. 
 (5) Wax clean the surface with a cotton cloth to the machine, into the cool and dry place, for the next use. 
 3 Notes 
 (1) The machine adopts the open-type motor, in a long time to work, the motor housing surface temperature up to 60-70. C, which is normal. 
 (2) there should be a host and the distance between the water tank to prevent water damage caused by spilled into the motor and burned out the motor leakage phenomenon. 
 (3) The unit used by the working fluid must be non-corrosive to copper and rubber, non-crystalline, not freezing, the liquid must be clear and free of impurities. 
 (4) non-air machine to prevent long-term operation reduced service life.
