6 - Maintenance
Lubrication
Transmission shaft
The universal joints and ball bearings should be lubricated with
grease. At the points shown
hours of use and the pipes and shafts
Diaphragm pump
Grease the pump after every 50 hours of use or once a month,
using the grease gun found in the crankshaft. The grease goes
along some internal channels in the crankshaft and reaches the
ball bearings, connecting rods, etc.
On both the 321 and the 363 pump models, greasing is done in
the same way.
A lack of grease in the pump could cause it to overheat
and all its inside mobile parts could break.
Filters and fittings
Check the filters after every 50 hours of use. As well as checking whether the filter is clean, make sure the mesh is
in perfect condition. If it is not, the filter will not be effective at all.
Not having filters in good condition leads to numerous unwanted stops during a working day.
Each time you dismantle a fitting to check the condition of the sealing or for any other reason, remember to
lubricate the sealing with oil or grease to avoid it from getting twisted when putting the fitting back in place.
A broken O-ring or sealing in the suction circuit means the pump will suck in air and the circuit will be hit by
very big variations in pressure and the hoses will shake.
