7. Replacing the power cable

Danger!
If the power cable for this equipment is damaged,
it must be replaced by the manufacturer or its
after-sales service or similarly trained personnel
to avoid danger.
8. Cleaning, maintenance and
ordering of spare parts
The equipment is almost completely maintenance
free. In order to ensure a long service life, howe-
ver, we recommend that you regularly check and
care for the product.
Danger!
The equipment must be disconnected from the

8.1 Servicing
•
If the equipment becomes clogged, connect
the discharge line to the water line and dis-
connect the suction hose. Open the water
line. Switch on the equipment several times
for approx. two seconds. This should resolve
the majority of clog-related problems.
•
Inside the pressure tank is an expandable
water sack and an air compartment whose
maximum pressure should lie at approx. 1.5
bar. Pumping water into the water sack cau-
ses the sack to expand so that the pressure in
the air compartment rises to switch-off level. If
the air pressure is too low, you should raise it.
To do so, unscrew the plastic lid from the tank
and top up the pressure to the correct level
using a tyre pump with meter at the valve.
Important: Be sure to completely empty
the water bag first using the water drain
screw (3).
•
Replacing the mains cable: Important:
Disconnect the equipment from the power
supply! A defective mains cable may only be
