Attention
Before any intervention, it is imperative to follow the
decompression procedure and the safety instructions.
During a long duration shutdown, stop the pump when
the piston is in the down position.
Pump
Make sure that the pump is clean and in good condition to increase
equipment working life.
Make sure that the suction strainer is clean and in good condition.
Regularly clean it and change it if necessary.
Flush the pump as often as necessary, specially when spraying
pigment-filled material.
Attention
Whatever the case, when stopping the pump, always
leave it filled with fluid.
For a short duration shutdown, if the flushing has not been
carried out, leave the pump filled with fluid.
For a long duration shutdown, after flushing the fluid,
leave the pump filled with solvent.
