MAINTENANCE

E.3
E.3.1

Preventive maintenance

Preventive maintenance is limited to filling of lubrication oil, visual inspection and cleaning. Particular
attention should be paid to high-pressure leaks and high-pressure hose. High-pressure leaks should be
repaired straight away as they may increase rapidly if left unattended. The method of repair depends on
where the leaks occur:
a. Pump Seal
A leak pump piston seal will cause a flow of water out of the drain hole on the bottom
side of the pump cylinder.
b. Threads
All threads are BSP standard. The sole exception is the spray nozzle, which is NPT. All
threads are assembled with sealing liquid, and leaks will normally never occur. How-
ever, if leaks should occur the threads must be cleaned and reassembled using either a
sealing liquid or thread tape.
c. High-pressure hose couplings
The high-pressure hose couplings have metal-to-metal seals. To stop a leak, tighten the
nut until the leak stops. If this does not work, open the coupling and inspect the sealing
surfaces.
High pressure cleaning is the best method for cleaning the unit.
If the plant air is contaminated, for instance by rust, an air filter should be fitted. A water filter should
be fitted if the water contains abrasive particles.
