sure that the closing panels have been correctly re-
assembled and anchored with the screws provided
before reconnecting the cleaner to the mains.
Failure to do so may cause a risk of electric
shock.
PRECAUTIONS AGAINST FROST
The cleaner must not be exposed to frost.
If the cleaner is left in premises where it is exposed
to frost, when work is over or for storage, antifreeze
must be used to prevent serious damage to the hy-
draulic circuit.
OPERATIONS FOR USING ANTIFREEZE (fig. 17).
1) Turn off the water supply (tap), disconnect the
hose and run the cleaner until it is completely empty.
2) Stop the water cleaner with the ON/OFF switch in
the "O" position.
3) Prepare a container with the solution of antifreeze.
4) Immerse the tube in the container with the anti-fre-
eze solution.
5) Start the water cleaner with the ON/OFF switch in
the "I" position.
6) Start the cleaner and let it run until antifreeze co-
mes out through the lance.
7) Suck up antifreeze with the detergent intake sy-
stem too.
8) Disconnect the water cleaner from the mains
electricity supply via the omnipolar switch or by un-
plugging the plug from the socket.
9) For high pressure cleaners provided with water
tank, the detergent solution prepared as described
in the point 3, must be poured directly into the tank.
Warning
Anti-freeze may cause environmental pollution.
Always follow the instructions given on the pack. (Di-

CHECKING PUMP OIL LEVEL AND OIL CHANGE
From time to time check the oil level in the high pres-
sure pump by means of the sight glass (fig. 18A) or
the dipstick (fig. 18B).
If the oil has a milky appearance, call the technical
service centre immediately.
Change the oil after the first 50 hours' work and sub-
sequently every 500 hours or once a year.
Proceed as follows:
1) Unscrew the drain cap situated under the pump
(fig. 18C).
2) Unscrew the cap with the dipstick (fig. 18).
3) Let all the oil drain off into a container and deliver
it to an authorized oil collection and disposal centre.
4) Replace the drain screw and pour fresh oil in
through the filling cap on top (fig. 19A) until it rea-
ches the level indicated on the sight glass (fig. 19B).
