1 Safety
1.1 Important information
If the equipment is used improperly, the high-pressure jet from the nozzle can be dangerous
and result in serious injury and damage. The water jet must never be aimed at people,
animals, active electrical equipment or at the high-pressure cleaner itself.
Before use, the high-pressure hoses, the high-pressure spray gun and the pump must all,
without fail, be inspected for possible damage. Hose lines must not be pinched, fed over sharp
edges, driven over by vehicles, tugged or bent. The rotary nozzle must not be operated if any
of the components mentioned above are damaged.
Any person engaged in operating, servicing, inspecting or assembling the equipment must be
appropriately qualified to carry out those tasks. The company operating the equipment must
produce precise instructions covering areas of responsibility, competence and how employees
are supervised.
Training and instruction must be given to any employees who do not have the necessary skills
and knowledge. If necessary, the manufacturer or supplier can provide this training on behalf
of the company operating the machine or pump. The company operating the equipment must
also ensure that their employees fully understand the contents of these operating instructions.
In addition to the safety instructions mentioned in these operating instructions, the
relevant statutory accident prevention and safety regulations must be observed and
adhered to!
1.2 Significant risks
Risk from the possible escape of liquid under high pressure
The water jet from high-pressure water jet equipment nozzles poses a risk due to its cutting
effect and its ability to penetrate objects, and because the high-pressure water jet nozzle and
hose may change direction or wander. Serious or even fatal injuries may be caused.
Hazardous substances may be released and it is also possible that parts of any object being
cleaned by the water jet may become loose.
Risk posed by handheld spray fixtures
Handheld spray fixtures pose a particular mechanical risk due to the recoil forces from the
water jet.
Risk posed by noise
Exposure to noise poses a risk. Exposure to noise can lead to loss of hearing, tinnitus or
physiological problems.
Noise can increase the risk of accidents because it may not be possible to hear alarms or
faults developing in the equipment.
Risk posed by vibrations
Pulsating vibrations from the pressure unit in handheld spray equipment poses a risk.

1.3 Danger from failure to follow the instructions
There are potential risks to individuals and the environment if the rules for using the equipment
set out in these operating instructions and in the safety instructions in particular are not
followed.
Please take note of Section 1.2, 'Significant Risks'.
1.4 Clothing and protective equipment
So as to operate the rotary nozzle safely, it is recommended that appropriate protective
equipment is worn, e.g. shoes with soles which provide a good grip, protective helmets,
hearing protection, goggles, visors, waterproof protection suits including protective gloves and
boots, high-pressure protective gaiters and aprons; high-pressure hose burst protection should
also be used.
1.5 Physical aptitude
Anyone working with the rotary nozzle must be well-rested, fit and in good health. Anyone
who, for health reasons, may not carry out strenuous tasks, should consult their doctor about
whether it is possible for them to work using the rotary nozzle.
No work should be carried out using the rotary nozzle after taking medication which has the
effect of slowing reactions or after consuming alcohol or taking drugs.
1.6 Proper use
The rotary nozzle is designed for use on manually-controlled high-pressure spray guns.
Particular attention should be paid to the instructions about operating the equipment for the
first time (Point 2) as regards the design of the nozzles (Point 3.2) and the permissible recoil
forces (see Point 3.3 below).
In addition, the relevant accident prevention regulations and any work instructions, operating
and safety instructions issued by the company owning the equipment should also be followed.
Possible applications for the equipment are listed below:
Refurbishing concrete and removing material
Cleaning surfaces
Deburring and cleaning castings
Removing layers of coating such as paint, etc.
Cleaning oil and gas platforms
Cleaning containers, metal gratings, construction machinery, etc.

2 Operating for the first time
2.1 Inserting and removing nozzles
1. Before fitting the nozzles, the high-pressure water jet equipment must be switched off.
2. If the nozzles have protective caps, these must first be removed before the nozzles are
fitted.
3. Apply metal lubricating paste to the screw connection threads on the nozzles.
4. Hold the nozzle head with an open-ended wrench (32mm wrench size) and screw the
nozzles in with an Allen key (5mm wrench size).
