OPERATING AND STARTING GUIDE
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
max. 20 m min. 2.5 mm
max. 30 m min. 4.0 mm
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, se technical specifications.
2. Connect the high pressure hose to the pres-
sure outlet (2.5). Flush the water supply hose
through and connect it to the water inlet
(2.3). The hose must be min. Ø, se technical
specifications.
The water supply pressure must be max. 10
bar during operation.
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).
FUNNCTIONS OF THE DRIVING HANDLE
Besides functioning as holder for pistol and
lance, more holders are carrying for extra
equipment on the driving handle.
The holders can be used according to the
illustrations.
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.

2 DETERGENT APPLICATION
2
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
adjustable nozzle by pulling the cover from
the pistol (please see fig. a. The high pres-
sure 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 and the Turbo
Laser, application of detergents can be car-
ried 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.
STANDARD EQUIPMENT
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 rec-
ommend 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 lance
and nozzle. This is not covered by the guarantee.
LANCES
Your new high pressure cleaner may be equipped
with one or more of the following lances:
SINGLE LANCE
is supplied with a fixed spray nozzle and a lance. It
is operated by means of the pistol grip.
DOUBLE LANCE
is supplied with a fixed spray nozzle and two lances
with the possibility of pressure regulation and
application of detergents. It is operated by means
of the pistol grip and the regulation handle.
SPECTRUM LANCE
is supplied with a high efficiency fixed spray noz-
zle and two lances with the possibility of pressure
regulation and application of detergents. It is oper-
ated by means of the pistol grip and the regulation
handle.
TURBO LASER LANCE
is supplied with a patented nozzle system that
provides an increased cleaning effect together
with two lances with the possibility of pressure
regulation and application of detergents. It is oper-
ated by means of the pistol grip and the regulation
handle.
ROTO JET LANCE
is supplied with a nozzle system that provides an
increased cleaning effect together with two lances
with the possibility of pressure regulation and
application of detergents. It is operated by means
of the pistol grip and the regulation handle.
ADJUSTABLE NOZZLE
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 rinsing).To choose high pressure the head of
the lance is pulled towards the pistol (fig. B).
3. Adjustment of the fan from concentrated (fig. C)
to fan-shaped (fig. D).
