Solution
The unit is not on a level surface. Place the unit on a level surface. If this
is impossible, the Auto-Vent must be on
the higher side of the unit.
The initial pot pressure is not set
correctly.
Conrm that the auto-vent valve is
working and set initial pot pressure 30
psi (2.0 bar, 0.20 MPa) above the blast
pressure.
The Auto-Vent is malfunctioning. Perform auto-vent clean-
ing procedure (see
Cleaning the Auto-Vent Valve, page 31).
A strong hose recoil occurs
frequently when the blast
control switch is engaged.
The diaphragm needs to be
ushed.
Perform the diaphragm
ush procedure (see
Flushing the Diaphragm Valve, page 29).
If ushing does not solve the problem, see
Repairing the Diaphragm Valve, page 30.
