Detergent Application; Maintenance; Oil Level; Oil Change - Nilfisk Gerni N/G-6400A Instrucciones De Manejo

Detergent application

Use only detergent which has been
developed specifically for use in high
pressure cleaners. It is economical in use
and is gentle on the cleaning object and
the high pressure cleaner.
1. Place the detergent hose with the
detergent filter in the tank con-
taining detergent. Check that the
detergent covers the filter com-
pletely.

Oil Level

Check the oil level of the pump on the oil
glass frequently. The oil level should be at
the "MAX" indication.
The oil level must only be read with the
high pressure cleaner switched off. (Oil
type - see technical data).
Used oil/water is collected in an oil waste
box (3.2). Empty the waste box as
required, by unscrewing the cap (2.36).

Oil Change

TThe pump oil should be changed after a
maximum of 300 working hours and at
least once a year. If there is water in the
pump oil (the oil turns white) the contami-
nated oil should be changed and new oil
added (oil type: See technical data).

Water Filter

Clean the water filter as required.
Disconnect the water inlet hose and
remove the water filter.

Fuel Filter

If there is water in the fuel filter (2.13)
replace the filter and empty the fuel tank
(2.11) by removing the fuel tank drain
plug and clean the tank.

Turbo Laser

Clean the filter in the Turbo Laser lance
(2.27) regularly. The filter is mounted in
the inlet opening at the throttle control to
prevent particles such as calcium and
sand from entering the Turbo Laser where
they may cause increased wear, leaks or
in serious cases operating malfunctions.
It may be necessary to change the filter. If
so, put a screwdriver or similar tool
through the filter and pull it out. Fit the
new filter with an O-ring and press it into
the opening of the Turbo Laser lance.
Make sure that the filter is placed with the
largest contact face towards the Turbo
Laser head.
When inspecting or replacing parts in the
Turbo Laser spray the metal parts with
"Pronto Universal", "WD 40", "Servisol",
"Caramba" or similar products that are
able to:
a. Counteract moisture
b. Protect against corrosion
c. Lubricate and clean
We also recommend the above men-
tioned treatment if the Turbo lance is not
being used for a long period of time.
2. The desired amount of detergent
(up to 6%) can be set on the
detergent regulator (2.29).
After using detergents, clean water
should be sucked through the pump.
Place the detergent hose in clean water,
and let the machine run for a few minutes.
NOTE! The detergent regulator must be in
pos. "0" when detergent is not being
used as the pump will suck in air.

MAINTENANCE

Water softener

To prevent deposit of calcium blocking
pipes, hoses and nozzles water softener
is added to the water which is poured into
the container (3.1). On the front panel
there is a water softener level gauge (5.1),
which indicates when re-filling is neces-
sary.

Decalcification

Even though the high pressure cleaner is
equipped with a water softener device we
recommend that the machine be regularly
descaled. Descaling is required if you find
a pressure increase of 5 bar or more over
operating pressure.
1. Place the detergent pipe into the
descaling acid.
2. Dismount the lance(2.30) from the
pistol(2.29).
3. Start the cleaner at pos. "1" and
let it run for 1/2 min.
4. Close the pistol (2.29) a few times
so the cleaner is also descaled in
the by-pass system.
5. Stop the cleaner and let the
descaling acid work for 5 min.
6. Restart the cleaner.
If the pressure is not down to the operat-
ing pressure the process is repeated.
After descaling the system must be with
clean water to remove acid residues.
Close the pistol a couple of times so that
the by-pass system of the cleaner is
flushed clean. The cleaner is then ready
for use again.
NOTE! Descaling acid is corrosive; wear
facial protection, protective gloves, etc.

Frost Protection

The best frost protection is to place your
high pressure cleaner in a frostfree envi-
ronment. If this is not possible, the high
pressure cleaner must be frost protected
as follows:
Empty the boiler shell at (4.2) and the
water box via the drain plug. Disconnect
the water inlet hose and pour 5 litres of
antifreeze into the water box (2.23). Start
the high pressure cleaner, activate the
pistol and let the machine run with the
pressure regulation handle in the open
position until antifreeze trickles from the
nozzles (2.1) and (2.2). Activate the pistol
trigger a couple of times to protect the
by-pass and safety valves. If your
machine is equipped with steame device,
turn the steam device on and repeat the
procedure to protect the steam system.
The antifreeze can be collected and used
again.
Cleaning
Always keep your high pressure cleaner
clean. This increases both the life and the
function of the individual machine parts
considerably.

Replacements/disposal

All replaced parts such as water filter, fine
sand filter, Turbo Laser filter as well as
contaminated oil and antifreeze must be
handed in to the local approved authori-
ty/institution for deposit/destruc-tion.
When the high pressure cleaner is no
longer to be used, the detergent as well
as pump and stator oil must be drained
off and delivered in accordance with the
above mentioned instructions. The high
pressure cleaner must likewise be hand-
ed in to the local, approved institution for
destruction.
Any replaced parts from service visits
may be given to the service personnel
who will deliver them to the proper author-
ity.
