Fitting the pump hose
1.
Clean the (new) pump hose on the outside and
fully lubricate it with Bredel Genuine Hose
Lubricant.
CAUTION
When the pressing shoes are worn the
compression force of the hose decreases.
If the compression force is too low, this
results in a loss of capacity by the backflow
of the liquid to be pumped.
Backflow results in a reduction of the life of
the pump hose.
