To attach connectors to the
hose you will require two
suitable spanners. One to
hold the hose and the other
to firmly attach the connector.
This joint must be tight.
Ensure bleed screw has been tightened
Adopt a comfortable, balanced stance
Keep back straight and flex knees to apply long
steady strokes
During prolonged usage the body of the pump
will become very warm. Stop pumping and
allow pump to cool down before continuing
As the pressure increases the pump will require
more force (this is normal). The maximum
working pressure of the pump is 315 bar
(4568 psi)
Unscrew the bleed screw to release pump
pressure
Fully tighten hose connector
joint using appropriate
spanners.
DO NOT use thread seal
tape or sealing washers.

material should be immediately replaced.
