If the power unit starts, but there is no suction through the hose
when connecting to the inlet valve mounted on the power unit,
the blockage is in the hose. To clear the hose obstruction, insert
a blunt instrument into the hose (a garden hose or similar) to
loosen the obstacle.
Seepage2,g.12and13
Youcanalsoattempttoreversethesuctionthroughthehoseto
