1. Introduction

The OERTZEN high pressure cleaner is one of the most durable and reliable
machines on the market. Its balanced ratio of water quantity and operating
pressure allows to carry out all cleaning and disinfection work. It conforms to
the National and European Safety Regulations. The CE label guarantees
fulfilment of all relevant National and European Safety Regulations (EN).

Important Notes
This operation manual should thoroughly and completely be studied and

considered prior to start-up of the unit.
We point out that we cannot be held responsible for any damages and/or

malfunctions which may be caused by disregarding this instruction
manual.

This manual is subject to technical alterations which are necessary to
improve the machine.

This manual to be made available to the operating personnel.

According to the rules and regulations for liquid blasters, item 6, as well as
VBG 87 (working with liquid blasters) the machine to be inspected yearly by
qualified personnel, in order to guarantee safe operation.

Inspection results to be recorded in writing and to be made available to the
authorities on request. OERTZEN service engineers are qualified according to
RFL and carry out all inspections at moderate prices.

This warning symbol appears in the operating manual at all
operating safety instructions dealing with dangers for per­sonal entirety and life (DIN 4844).

This warning symbol appears in the operating manual at all
operating and safety instructions dealing with the fulfilm ent
of rules, regulations and instructions for the proper opera-
tion and to avoid damages or destroying of the machine.

All rights reserved. Any use in other than legally authorised cases requires the
prior written approval of ARNDT H. von OERTZEN ( GmbH&Co).

2. Safety Instructions
This operation manual should thoroughly and completely be studied and

considered prior to initial start-up of the unit. When strictly following the
instruct io ns, no dan ge r shoul d oc cur .

This machine must only be operated by qualified personnel who are fully
familiar with the operation and possible dangers. The operating instructions
laid down in the “Regulations for liquid blasters (ZH 1/406)” as well as
“Working with liquid blasters” (BGV D 15) strictly to be followed.

The machine is not suitable for unattended operation. Protective clothing to be
worn.

The water stream emerging from the spray pistol at high speed has a rather
dangerous cutting effect. So, never direct the water stream onto persons or
animals, nor direct it onto electric units. When starting the machine, be aware
of torque and recoil. Take care of stable foothold.

The max. pressure stated on the nameplate must not be exceeded. The safety
valve opens as soon as the max. operating pressure is exceeded by 10 %.
The safety/control valve is workshop adjusted and sealed. The adjustment
must not be changed.

Indoor operation of oil-heated high pressure cleaners is not permitted in case
proper ventilation and exhaust evacuation is not guaranteed. Exhaust gas is
harmful!

Unsuitable or defective high pressure hoses very often cause accidents during
operation of high pressure cleaners. Therefore, check the hoses for damages
before any start-up. Defective hoses immediately to be replaced by original
OERTZEN equipment. Using other materials than original OERTZEN equip­ment (union respectively hose marked with “OERTZEN”) or using materials
which have not expressively been approved by OERTZEN in writing voids all
warranties and product liability.

Worn out and/or defective high pressure hoses must never be repaired and
reused, but replaced immediately.

Spray pistols with delayed closing mechanism must not be used, due to risk of
injuries.

Lever in open position must not be blocked or fixed in any other way.
When using spray lance of less than 750 mm length particular dangers to be

considered.

5

The unit must not be placed or operated in areas jeopardised by fire or
explosions. During working at fuel stations the “Technical Rules for flammable
Liquids” (TfbF) to be considered.

Consumables to be handled thoroughly. Technical safety regulations and
environmental rules to be followed. Machine not to be started in case power
cable, plugs, switches, etc. are defective.

Extension cables to have a diameter according to VDE regulations. Extension
cables on reels to be reeled off completely, in order to avoid overheating of the
cable reel.

Machine not to be started in case power cable, plugs, switches, etc. are
defective.

When opening the machine in case of malfunction or emergency, the unit to be
switched off by means of the ON/OFF switch and to be disconnected from the
electrical network.

Electric energy can cause severe injuries. Electrical components thoroughly
and frequently to be checked for damages and malfunctions, in order to avoid
any cause for accidents. All repair work to be carried out by qualified
personnel. Disconnect the unit from the electrical network during all
repair/maintenance work. (ZH 1/95).

Make sure that the unit cannot move. In case the unit is equipped with a brake;
it should be activated during working in steep areas.

During loading suitable lifting eyes to be foreseen. Balanced load to be
ensured.

Repair work within the high pressure section of the machine (pump, hoses,
piping) only to be carried out by qualified engineers.

The exhaust evacuation area is hot! Do not touch!
After work the spray pistol to be protected against accidental/unauthorised use

by means of the safety lever.

According to safety rules (BlmSchV) the oil-heated high pressure cleaner
to be inspected within 4 weeks after delivery. Exhaust gas measurements
to be taken and to be repeated yearly.

3. Design, Operation, Illustrations

The hot water high pressure cleaner comprises an inline plunger high pressure
pump with safety shut-down system a high capacity oil heating system with
stainless steel heat exchanger.

The high pressure pump is directly flanged to the electric motor. It sucks the
feed water from a level controlled water tank and directs it via the safety/
control unit into a heating coil where it is heated up to operating temperature.
Between high pressure pump and heating coil a safety/control valve is installed
which opens as soon as max. operating temperature is exceeded by more
than 10 % and returns the water which is not taken by the nozzle into the
suction line of the pump.

By activating the heating system, the fuel pump sucks fuel from the storage
tank via a filter system and injected into the burner chamber. The required
oxygen is pressed into the burner chamber by a blower system. The mixture is
atomized and ignited by the ignition electrodes which are continuously
powered by the high voltage transformer. The heating flame totally burns
without touching the heat exchanger shells. During this procedure infra-red
rays are generated which, in common with hot exhaust fumes, economically
heat up the water to the working temperature which is adjusted at the
thermostat.
The working pressure can continuously be adjusted by means of the adjusting
handle at the double lance.

If required, suitable detergent can be injected into the water stream from the
storage tank, via filter and non-return valve and applied onto the cleaning
object.

In order to protect the machine against formation of mineral deposits, an anti­scaling system is installed which continuously feeds an anti-scalant liquid into
the water storage tank.

The machine is equipped with a safety shut-down system. When closing the
spray pistol the machine keeps on running for approx. 15 seconds in
circulation mode and afterwards switches into stand-by mode. In prallel, a
safety-/control unit interrupts the fuel supply so that the burner is deactivated.
When releasing the spray pistol again, the machine is restarted, pressure
generated and burner activated, so that the cleaning task can be continued
without delay.
