• Remove the suction hose and the rubber hose
(
J7
)
and take
away the bucket of water
(
J6
)
.
• Now point the spray gun
(
J4
)
into the container
(
J5
)
and
press the trigger to recover any cleaning liquid left.
• As the pump idles, press the
“
OFF”
(0)
switch
(J2)
to stop
the tooling.
• In case of long storage, we recommend you to suck and
to leave light mineral oil inside the pumping group and the
flexible hose
.
CHECK ON THE PACKING NUT
The gaskets do not need adjusting. The ring nut is only used to
fit and remove gaskets and for topping up the oil.
ROUTINE MAINTENANCE
• Use the lubricant
(
K1
)
provided
(ref. 16340)
to make it easier
to slide the piston inside the seal pack and to substitute the
air with oil.

Oil ring
Follow the washing procedure before using again
the equipment.
If the equipment is to be stopped for a lengthy
period of time, carry out the cleaning operations
described previously, according to the type of
product used. In case of short stoppages, suck
in some water and leave the pump unit in the
bucket (J6) for a few minutes.
K
At the start of each working day check that the
ring nut is full of hydraulic oil (Ref. 16340). This
oil makes it easier for the piston to slide and
prevents any material that escapes via the seal
gasket drying when the equipment is stopped.
