5.0 Operation

5.1 Starting-up

procedure

1. Check the oil level in the oil glass. The level

should be maintained between the MIN. and
MAX. marks. This applies also for the oil level in
the oil-mist lubricator (pos. 5).

2. Run water through the inlet hose before connec-

ting, in order to remove possible impurities in the
hose. Connect the hose.

3. Connect the quick coupling (a) of the high pres-

sure hose to the outlet socket.

4. Check the input end of the spray lance (b) for

possible impurities. Pull forward the grey trigger
(c) of the spray handle. Connect the input end of
the spray lance to the quick coupling. Release
the grey trigger.

5. Press the trigger of the spray handle (d) and

allow the water to run, until the system has
been completely vented. For self-priming it is
recommended to open the regulating valve (e)
during the venting.

6. Release the trigger of the spray handle (d) and

turn on the air supply. The pump will now be in
idle motion.

7. For cleaning at high pressure press home the

trigger of the spray handle after having closed
the regulating valve.

8. For cleaning at low pressure open the regula-

ting valve. When cleaning at low pressure the
chemical injector will allow supply of detergents
according to the scale of the injector situated at
the water outlet.

Operation

5.2 Stopping

1. Turn off the air supply.
2. Turn off the water supply.
3. Press home the trigger of the spray handle to

relieve the pressure of the cleaner.

4. Do not disconnect the high pressure hose, until

the cleaner has cooled down and stopped.

6.0 Frost proofi ng

Operation and storage in frosty weather (below
0°C).

Never leave the cleaner unless it has been emptied
of water, not even for a short period. Empty the
cleaner in the following way:

1. Disconnect and empty both the water supply and

the high pressure hoses.

2. Start the pump and allow it to run until it is

empty.

If the cleaner is not stored in a frost-proof place
between operations, it should be protected from
frost in the following way:

1. Disconnect the lance.
2. Start the machine and allow it to run without

water.

3. Place the suction hose into a container of anti-

freeze.

4. Draw in the antifreeze from the container by

activating the spray handle. Having placed the
spray handle above the an ti freeze funnel, open
and close it a few times, so that the antifreeze
can circulate.

5. Remove the inlet hose from the container. Acti-

vate the spray handle and allow the rest of the
antifreeze to run back into the container.

NB! The antifreeze will be diluted with water and

will after some time lose its effect.

IMPORTANT:
To avoid damage always ensure that the cleaner,
the hoses and the spray lance are unfrozen before
restarting. Place the cleaner and the accessories in
a warm place for some time before starting up.
