PLANNED MAINTENANCE
General test (to be carried on using the equipment accessories of the machine): pressure, temperature, electric absorption, regu-
lation of the detergent flow. Times of maintenance and replacement of the components are calculated in multiples of 250 hours,
so that interventions become standard and you have a programmed maintenance of the pressure washer. If we fill a schedule with
the components that need maintenance or replacement in order of the usage (250, 500, 750, 1000 hours), the result you will get is
a plan of programmed work, as follows in the enclosure.
