MAINTENANCE - Fig. 38 to 40
English
Fig. 38 – CLEANING OF THE PRIMARY FILTER at the inlet of the HP cleaner
Check on a regular basis the state of the water filter placed in the quick coupling of the
pump inlet: A simple sand grain can result in valve breakdown (symptoms: pressure loss and
vibration in the HP hose) or By-pass breakdown.
Fig. 39 & 40 – Axial Pump
The cleaner-unclogger is equipped with an axial pump whose 3 pistons are activated by an
oblique disk system: A flask contains the oil which enables the lubrication of the moving parts
by splash lubrication (no loss, contrary to an automobile!).
The factory set oil level does not need to be changed often.
The oil, in time, will lose its lubricating power and be saturated with small metal particles
(created by the friction of the parts), and it will be necessary to have it changed after 2 years, or
1 and a half years if you make intensive use of your cleaner (over 100 hrs /year).
