1b. Obstruction in the hose. A blockage in the hose
can be determined by inserting the hose into any
wall inlet and, while power unit is running, check
each additional inlet for normal suction by holding
the palm of your hand over the open inlet. If normal
suction is felt at all other inlets, insert the hose
into a second inlet. If the blockage still exists it is
located in the hose. However, if the blockage
does not occur when the hose is changed, the
blockage is probably located in the tubing
system leading to the original inlet.

valve at power unit. Turn unit on. This
will reverse normal air flow through the
hose and dislodge any clogs.

unit running, place the palm of your hand
over the opposite end of the hose. When

seconds and then quickly remove your
hand. This procedure repeated several
times should clear the obstruction. If the
blockage is not cleared, contact your
nearest Service Center.
