CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic components if
they are manipulated or opened due to pressure in the liquid
end and adjacent parts of the system.
– Disconnect the pump from the mains power supply and
ensure that it cannot be switched on again by unauthor‐
ised persons.
– Depressurise the system before commencing any work
on hydraulic parts.
CAUTION!
Warning of feed chemical spraying around
An unsuitable feed chemical can damage the parts of the
pump contacted by the chemical.
