MAINTENANCE
ATTENTION! It is imperative that the machine be
deenergized by unplugging the plug before all
work and maintenance work. Otherwise there is
a danger of short-circuiting! Wait until the green
operating light has gone out.
Repairs may only be carried out by qualified per-
sonnel who dispose the corresponding training
and experience. The device must be tested by a
skilled electrician after every repair.
The machine is designed so that a minimum of care and main-
tenance is required. However, the following work has to be
carried out and components checked regularly:
9.1
MECHANICAL MAINTENANCE
• Keep the thread on the pump unit clean.
• Check the seals at all the couplings and connecting pieces
for leaks. If appropriate, replace worn seals.
• Check the following for damage before every usage:
- High pressure hose
- Power cable
- Control unit

ELECTRICAL MAINTENANCE
• The electrical drive and its ventilation slots must always be
kept clean and may not be cleaned with water. Danger of
short-circuits.
9.3
LONG PERIODS OF NON-USAGE
If the machine is not used for a longer period, it has to be
cleaned thoroughly and protected against corrosion. Store
the appliance in a dry and frost-free place.
In the event of interruptions / storage, the
pump unit must always be filled with con-
servation agent. Otherwise the stator may
stick to the rotor and damage the pump. In
the event of interruptions of up to 5 days, use
PlastGuard (Art. No. 2399 959, mixing ratio
with water 1:5) and for longer periods of stor-
age use PlastGuard longlasting (Art. No. 2399
960, undiluted).
