USER MANUAL
The pump has been tested before getting out from the line of production and
therefore it is ready to work. Before starting to work, it is anyhow advisable to
check the oil level and all the fi ttings, as well as if the bolts which hold it to the
sprayer are all tight.
The oil lever need to be verifi ed daily, or more frequently if the sprayer would
be working in heavy conditions.
The oil reservoir has never to be completely full. The oil level has to be about at
the middle of the glass.
The oil to be used is of the type anti-foam SAE 2O W 4O.
The oil of the pump needs to be replaced at the end of every season or at least
every 500 hours of work.
Some pumps are provided with an accumulator to control the pressure, in or-
der to avoid vibrations and pulsation.
The pressure of the accumulator has to be checked periodically with a gauge.
The correct pressure setting of the accumulator is shown on the manual of the
pump and, as reference it has to be the 10% of the pressure used for working.
For any more information about the pump, read and understand the manual of
the pump.

see parts list for your model ), with manifold removed, valves can readily be
