10.5.1
OIL CHANGE
Change the oil for the first time after the first 10-20 working hours and after that every 300 working
hours. Also check the membranes when changing the oil. Replace damaged or worn membranes with
new ones. It is recommended to change the membranes every 300 working hours.
10.5.2
MEMBRANE CONTROL FOR PUMP 150/20, 105/20, 65/30
To check the membranes, first of all unscrew the bolts on the covers of the pump and release the
suction and pressure collector. After that, unscrew the bolts on the covers and remove the chambers.
Carefully inspect the upper and lower side of the membranes. Release the oil at the same time.
It is recommended to clean the inside of the pump and its vital parts with diesel oil before
reassembling the pump. Assemble the pump in reverse order. Be careful to correctly insert the valves
(see the catalogue). After that, pour fresh oil into the pump. For pump BM 150/20, oil needs to be
poured in through the oil pot.
While pouring oil into the pump, turn the shaft of the pump several times by hand in order to
press out any excess air which is caught between the piston and the membrane. Pay attention to
the oil level.
Turn on the pump for few minutes at minimum pressure. Pay attention to the functioning of the pump
and add some oil if needed.
10.5.3
INSTRUCTIONS FOR DAMAGED MEMBRANE
If the oil in the oil pot of pump BM 150/20 whitens, immediately stop operating the machine and
replace the damaged membranes. On the opposite, the pump can be heavily damaged. It is also
possible to recognise a damaged membrane by means of the manometer, since its pressure pointer does
not come to a halt.
10.5.4
MAINTENANCE
After every single use, it is recommended to wash out the inside of the pump as well as other parts of
the sprayer with clean water (see chapter 7.11.2), and after season, the pump must be prepared for
winter (see chapter 15.6).
WARNING: All depositing in nature is illegal, therefore, oil must be collected in
appropriate containers at appropriate collection centres!
