Diaphragm pump
Grease the pump every 50 working hours or once a month, through the
grease nipple situated on the crankshaft axle. The grease goes along the
grooves in the crankshaft to reach the crankcase where it is distributed
around bearings, conrods, etc.
Greasing is carried out in the same way on both pump models 363 and
463.
Pump model 364 and 464 have external central grease nipples
μ
ATTENTION! Insufficient greasing of the pump could cause it
to overheat and break the moving parts inside.
Filters and fittings
Revise the filters every 50 working hours. Apart from ensuring that they are clean, make sure that the mesh is in good
condition. Otherwise, the effectness of the filter will be nil.
Whenever dismantling any filter or hose pipe, take care not to pinch the o-rings fitted to them. When replacing the pipe
fitting, smear the o-ring with oil or grease so that it falls easily into place in its groove.
μ
ATTENTION! If the filter is not in good condition, it could cause numerous undesired stoppages during the working
day, extending the working time required.
μ
ATTENTION! Each time you remove a fitting to check the condition of its o-ring or for any other reason, remember to
lubricate the seal with oil or grease to prevent it from being pinched or breaking when reassembling the fitting in its
housing

ATTENTION! Insufficient greasing of the pump could cause it to overheat and break the mobile parts inside.
