Clearing Blockages
Blockages in the hose can cleared by taking the hose
off the machine. Squeeze the retaining ring (3) and
remove hose.
If there is no visible blockage, place wrong end of
hose in connecting tube (24), hold it upright with one
hand, block the top with other hand and switch
machine on. If necessary, rapidly lift your hand on
and off the end of the hose.
Never use anything sharp to clear the hose.
Check for a blockage in the swivel neck of the power
head and under the yellow trap-door (45) on the
bottom of the power head. Ensure that the passage
between these two openings in the power head is
clear.
