STARTING
a) Follow the pump Manual instructions.
b) The pump must turn at a rotation speed between 400 - 550 rpm.
c) To prime pump quickly, keep the suction circuit at “0” pressure or near to “0”. Repeat this operation each
time the pump is emptied.
d) Bring the pump to the rated pressure according to the type of work to be carried out by regulating the
pressure of the control. The pressure must not exceed the maximum pressure of the pump.
e) Monitor the oil level during the first few hours of operation and add oil (when pump is idle) if necessary.
MAINTENANCE
Wash the pump after use by running clean water through it for a few minutes.
ATTENTION: before staring the pump, make sure that taps not in use are in
the “closed” position (fig. 4).
ATTENTION: Make sure that the moving parts of the pump are properly pro-
tected and are not accessible to other persons not authorized.
NOTICE: if the machine is used at a very low temperature, make sure there
is no ice inside the pump and manifolds, turning the eccentric shaft of the
pump by hand, after disconnecting it from the tractor.
NOTICE: Avoid exposing pump to freezing temperatures. If this is unavoid-
able run antifreeze through pump for several minutes then purge system of
any antifreeze before use.
Preliminary Maintenance
A) Check oil level, when pump is idle and placed horizontally, it must be at the mark indicated on the oil site
glass (fig. 1) or be visible on the oil level plug (fig. 2), depending on type of pump. Top off with SAE 30W non-
detergent oil if necessary.
