Periods Of Inactivity - Elektro Maschinen HDEm 662 Bedienungsanleitung

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 (fig.10A).
3) Prepare a container with the solution of an-
tifreeze.
4) Immerse the tube in the container with the
anti-freeze 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
comes out through the lance.
7)Suck up antifreeze with the detergent intake
system too.
8)Switch off the cleaner and disconnect the electric
power by switching off the omnipolar switch,via
the omnipolar switch or by unplugging the plug
from the socket.
Anti-freeze may cause environmental pol-
lution. Always follow the instructions given
on the pack. (Dispose of carefully.)
CHECKING PUMP OIL LEVEL AND OIL CHAN-
GE.
From time to time check the oil level in the high
pressure 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
subsequently 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 di-
sposal centre.
4) Replace the drain screw and pour fresh oil
in through the filling cap on top (fig. 19A) until
it reaches the level indicated on the sight glass
(fig. 19B).
For water cleaners without oil drain bung,
contact our technical service centre for re-
placement.
Use only SAE 15 W40 oil.
CLEANING THE WATER FILTER
Clean the water intake filter regularly and free it
from any impurities (fig. 20).
CHANGING THE HIGH PRESSURE NOZZLE.
The high pressure nozzle fitted on the lance must
be changed from time to time, as this component
is subject to normal wear during use. Wear may
generally be detected by a drop in the working
pressure of the cleaner. To replace it, consult your
supplier and/or dealer for instructions.
