DESCRIPTION
29
Your new high pressure cleaner is constructed as shown in the
functional diagram and drawing No. 2. The machine consists of
an electric motor (2.1), which drives the high pressure pump
(2.2).
Through the water filter (2.4) the pump sucks the water from the
water inlet (2.3) into the cylinder head. The pump pressurises the
water and forces it out through the pressure outlet (2.5), into the
high pressure hose (2.6), to the pistol (2.7), and out through the
Turbo Laser nozzle (2.8).
The pressure of the high pressure cleaner can be read on the
pressure gauge (230A/250A/270A) (2.10). If the water pressure
exceeds the normal working pressure, the built-in safety valve
(2.12) will open the by-pass and thereby prevent damage to the
high pressure cleaner.
When the pistol trigger is released, the motor will stop.
Detergent is added through the detergent hose from an external
tank. Adjustment of the concentration continues on the dosing
valve (2.15).
NB! When the high pressure cleaner is supplied with hot water
above 30°C, the pump must not suck water from a tank or the like,
but should be fed with pressure. At temperatures between 30 and
40°C, this pressure should be min.1 bar - between 40 and 60°C:
min. 3 bar.

OPERATING AND
STARTING GUIDE
High pressure hose
Your new high pressure cleaner is equipped with a heavy duty
high pressure hose. Do not attempt to pull at the high pressure
hose when moving the high pressure cleaner. Be careful not to
run over or in any other way damage the high pressure hose. The
warranty does not cover broken hoses or hoses which have been
run over.
Fine sand filter
If you use water containing floating sand, we recommend that you
mount a fine sand filter. The filter element is changed according to
need. If a fine sand filter is not mounted, the fine sand may get in
the valves of the pump and cause damages on the safety valve,
cylinder head and possibly the Turbo Laser. This is not covered
by the guarantee.
Adjustable nozzle (N/G-230A/240A/250A)
The nozzle has three important functions:
1. Operation at low pressure (with fluid detergent).
To choose low pressure the head of the lance is pushed
away from the pistol (fig. a).
2. Operation at high pressure (for powerful wash and rins-
ing).
To choose high pressure the head of the lance is pulled
towards the pistol (fig. b).
3. Adjustment of the fan from concentrated (c) to fanshaped (d).
Turbo Laser (N/G-250) (N/G-230A 100/110V)
The high pressure cleaner is also equipped with a Turbo Laser
lance for highly improved cleaning efficiency (see technical data).
SPECTRUM (N/G-270)
The high pressure cleaner is provided with a lance with a high
efficient high pressure
SPECTRUM nozzle which performs a
cleaning efficiency higher than traditional flat jet nozzles. Furthermore, the N/G-270 is provided with a handle for pressure regulation and for application of detergents.
Starting
If you require the high pressure cleaner to work with an action
radius larger than its standard, you should lengthen the high pressure hose and not the electric cable. If you still wish to extend the
electric cable the dimensions should be as follows:
Length of cable cross-sectional area
max. 12 m min. 1.5 mm
2
max. 20 m min. 2.5 mm
2
max. 30 m min. 4.0 mm
2
The high pressure cleaner must be situated as far away from the
cleaning site as possible.
1. Connect the electric cable. Note the rated voltage and
amperage of the high pressure cleaner :
Model 230 240 250 270
1x100V, 50/60Hz 14A
1x110V, 50Hz 13A
1x230/240V, 50Hz 10A 9,5 13/12A
1x230/240V, 60Hz 13/12A
3x230V, 50Hz 10.5A
3x400/415V, 50Hz 6A
2. Connect the high pressure hose to the pressure outlet
(2.5). Flush the water supply hose through and connect it
to the water inlet (2.3). The hose must be min. 1/2”(N/G270: min. 3/4”).
The water supply pressure must be max. 10 bar during
operation.
Make sure the dosing valve (2.15) is in position “0”
(closed).
Turn on the water.
3.. Start the machine and let water run through the pistol.
Activate the pistol a few times and check that no air is
present in the system (when the water flow is steady and
not knocking). Then mount the lance on the pistol.
4 Activate the pistol (2.7) and let the high pressure cleaner
run till stable pressure is obtained (complete bleeding).
Now the high pressure cleaner is ready for use and by
means of the adjustable nozzle the raditation angle can
be adjusted (please see fig. c+d, page 8).
On the
SPECTRUM lance (N/G-270) and the Turbo Laser,
the pressure is regulated on the handle to the double
lance.

OPERATING AND
STARTING GUIDE
Stopping
To stop the high pressure cleaner, turn the selector switch (2.17)
to pos.”0”. Switch off the power for the high pressure cleaner at
the main switch and turn off the water supply.
Always lock the pistol with the safety device on the handle when
you put down the lance. This will prevent any unauthorised personnel from immediately using the high pressure cleaner.
Detergent application
Use only high pressure 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 containing high pressure detergent. Check that the
detergent covers the filter completely.
2. Open the head of the lance (2.9) on the nozzle by pulling
the cover from the pistol (please see fig. a, page 8). The
high pressure cleaner will automatically suck detergent
until the head of the lance is pushed back to the starting
point. The concentration can be adjusted on the dosing
valve (2.15).
On the
SPECTRUM lance (N/G-270) and the Turbo Laser,
application of detergents can be carried out by turning
the regulation handle.
NOTE! After use of detergents, clean water should be sucked
through the pump. Place the detergent filter in clean water, and let
the machine run for a few minutes.
31
MAINTENANCE
To obtain the optimum return and the longest possible life for your
high pressure cleaner, it is important to maintain the machine. We
recommend that you follow the following directions and refer to
the check list on the next page.
Oil change
Normally, it is not necessary to check the oil level of the pump
again. If it is, however, wished to be more careful with the pump,
oil replacement can proceed as follows:
- dismount the body
- unscrew the oil plug of the pump
- drain the oil by placing the machine horizontally
- add oil in level with the lower edge of the oil filling hole
(for oil type and quantity please see the technical data).
Water filter
Clean the water filter (2.4) as needed. Dismount the hose
screwed connection and remove the water filter.
Turbo Laser
Clean the filter in the Turbo Laser lance regularly. The filter is
mounted in the inlet opening 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. Mount 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.
Frost protection
The best frost protection is to place your high pressure cleaner in
a frost free environment. If this is not possible, the high pressure
cleaner must be frost protected as follows:
Dip the water inlet hose in a container holding 5 litres of
antifreeze/water mix. Start the machine by turning the switch
(2.17) to pos. “I”, activate the pistol and let the machine run at low
pressure until anti-freeze comes out of the nozzle (2.8). Release
the pistol trigger a couple of times to frost protect the by-pass and
safety valves. The anti-freeze can be collected and used again.
Cleaning
Always keep your high pressure cleaner clean. This increases the
life and function of the individual parts considerably.
Disassembly/disposal
All replaced parts such as water filter, fine sand filter, Turbo Laser
filter as well as contaminated oil and anti-freeze must be handed
in to the local approved authority/institution for deposit/destruction.
When the high pressure cleaner is no longer to be used, the
detergent as well as pump oil must be drained off and delivered
in accordance with the above mentioned instructions. The high
pressure cleaner must likewise be handed 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 authority.
