1. After starting the engine, pull down the vacuum pump handle. (As Pic 6)
■
2. Check the water comes out from the drainage pipe or not, the pressure gauge point to the positive range.
■
3. Return the vacuum pump handle to original position
NOTICE:
* No water come out after 30seconds; check the relevant items on “Fault handling table”
* Water should not be lower than 9m, otherwise the pump could not suction.

open the outlet valve. Please re-operate the vacuum pump. If suction hose accumulate air, open the outlet
valve; run the vacuum pump every 3-5seconds, till the water flow fluently.
* Inspect the height of the water frequently when spraying. The hose filter should be 30cm below the water. If
there is much sediment in the water, use dense mats or meshes to keep it away.
■
4. Open the outlet valve. (As Pic 7)
* Notify the nozzle operator before open the outlet valve.
* The outlet could be rotated about 90 degrees, stop the engine and open the valve when rotating
